Description

Technical Field

[0001] The present invention belongs to the technical field of engineering pile foundation detection. More specifically, the present invention relates to an assembled ballast water tank dedicated to an engineering pile foundation detection ballast platform. Background Art

[0002] With the continuous increase of large-scale and high-rise buildings, the foundation form of using pile foundations in foundation engineering also increases accordingly. At present, most of the methods used for the ballast detection test of pile foundations in the construction engineering field are the ballast method, the anchor pile method and the ground anchor method. These methods all use hydraulic jacks to apply loads on the pile tops of test piles, and the reaction force of the jacks is balanced by the piled weights on the reaction frames in the ballast method; the ballast method must solve the problems of the source, stacking and transportation of hundreds of tons or even thousands of tons of loads. The large-volume concrete blocks required by the ballast method lack effective enclosure protection, and often there are phenomena such as the concrete blocks slipping and the entire ballast body collapsing during the detection test, resulting in production safety accidents such as casualties of on-site detection staff. At the same time, all ballast detection methods have problems such as the installation and disassembly of each component and the long time in the process of detecting and testing.

[0003] The anchor pile method must set multiple anchor piles and reaction girders. Multiple anchor piles not only require expensive costs, long maintenance time and high costs, but are also easily restricted by tonnage and site conditions and cannot perform random spot checks; during the test process of the anchor pile method, when the applied pressure is too large, it may cause the welded joints of the main reinforcement bars of the anchor piles to crack or be pulled off, which will directly cause the collapse of the reaction frame combined with the steel beam and the anchor piles. This will not only damage related detection instruments such as jacks and displacement sensors, but also pose a hidden danger to the safety of test personnel.

[0004] The Chinese patent with the application number 2018218707487 is the applicant's prior application, which discloses an assembled ballast box for an engineering pile foundation detection ballast platform. It can be assembled and disassembled on site, reduce the costs during transportation and hoisting, facilitate the hoisting and assembly of the ballast body, improve the safety factor during disassembly and detection tests, and greatly improve work efficiency. However, there are still technical problems such as many on-site installation components, difficult and time-consuming on-site assembly and combination, high hoisting costs and long hoisting time. Summary of the Invention

[0005] An object of the present invention is to solve at least the above defects and provide at least the advantages described later.

[0006] Another object of the present invention is to provide a prefabricated ballast water tank dedicated to the ballast platform for engineering pile foundation detection. Two or more prefabricated ballast water tanks are tightly fastened to each other vertically to form a ballast body, reducing the on-site assembly procedures and difficulties between the ballast water tanks, thus reducing the labor intensity, ensuring the overall structural strength of the ballast water tank and reducing the risk of collapse. During use, two or more ballast bodies are stacked and connected to each other vertically, horizontally, and then water is added to jointly form a combined ballast body with a larger weight for static load detection tests on the pile foundation. Since the box body and the water body are separated, users only need to transport and hoist the box body, and they can move this prefabricated ballast water tank arbitrarily, while being convenient for transportation, hoisting and storage, greatly improving work efficiency and economic efficiency.

[0007] To achieve these objects and other advantages of the present invention, the present invention provides a prefabricated ballast water tank dedicated to the ballast platform for engineering pile foundation detection, comprising:

[0008] Upper rotating support arm: It is made of hard material. The outer shape of the upper rotating support arm can be selected as cylindrical, square columnar, or plate-shaped. The bottom end of the upper rotating support arm is fixedly connected to each end corner of the assembled ballast water tank body through the rotating shaft. The bottom end of the upper rotating support arm is fixedly connected to the top end of the rotating shaft member facing the far end. The top end of the upper rotating support arm rotates in a circle with the rotating shaft member as the center. The top end of the upper rotating support arm is provided with a concave or convex part, and the concave or convex part is tightly nested and movably connected to the concave or convex part provided at the top end of the lower rotating support arm through the rotating shaft member; when entering the working state, use a crane to lift the assembled ballast water tank above an assembled ballast water tank. As the distance between the upper and lower assembled ballast water tanks continues to increase and separate, the upper rotating support arm and the lower rotating support arm will also continuously rotate and expand on their own. When the upper rotating support arm and the lower rotating support arm are rotated and lifted to a vertical state, then install the bolt, so that the upper rotating support arm and the lower rotating support arm in a vertical state cannot continue to rotate and maintain a vertical and stable working state; when ending the working state, remove the bolt, and the upper rotating support arm and the lower rotating support arm connected up and down on the ballast body can return to the rotatable state. Use a crane to continuously lower the assembled ballast water tank above an assembled ballast water tank. The upper rotating support arm and the lower rotating support arm can rotate and lower continuously by virtue of the weight of the assembled ballast water tank above them. As the distance between the upper and lower assembled ballast water tanks continues to decrease and close, the upper rotating support arm and the lower rotating support arm are rotated and closed and then retracted into the storage box on each assembled ballast water tank and are in a storage state. After the upper and lower two assembled ballast water tanks are completely lowered, the bottom surface of the upper assembled ballast water tank and the top surface of the lower assembled ballast water tank are in contact with each other, which can reduce the stacking volume and facilitate the transfer of the engineering pile foundation to continue ballast testing or withdraw from the engineering pile foundation testing site.

[0009] Lower Rotating Support Arm: It is made of hard material. The outer shape of the lower rotating support arm can be selected as cylindrical, square columnar, or plate-shaped. The bottom end of the lower rotating support arm is firmly connected to each end corner of the assembled ballast water tank body through the rotating shaft. The bottom end of the lower rotating support arm is firmly connected to the top end of the opposite distal end and the rotating shaft member. The top end of the lower rotating support arm rotates in a circle with the rotating shaft member as the center. The top end of the lower rotating support arm is provided with a concave or convex part, and the concave or convex part is tightly nested and movably connected to the concave or convex part provided at the top end of the upper rotating support arm through the rotating shaft member. When entering the working state, use a crane to lift the assembled ballast water tank above an assembled ballast water tank. As the distance between the upper and lower assembled ballast water tanks continues to increase and separate, the lower rotating support arm and the upper rotating support arm will also continuously rotate and expand on their own. When the lower rotating support arm and the upper rotating support arm are rotated and lifted to a vertical state, then install the bolt pin so that the lower rotating support arm and the upper rotating support arm in a vertical state cannot continue to rotate and remain in a vertical and stable working state. When ending the working state, remove the bolt pin, and the lower rotating support arm and the upper rotating support arm connected up and down on the ballast body can return to the rotatable state. Use a crane to continuously lower the assembled ballast water tank above an assembled ballast water tank. The lower rotating support arm and the upper rotating support arm can rotate and lower continuously by means of the weight of the assembled ballast water tank above them. As the distance between the upper and lower assembled ballast water tanks continues to decrease and close, the lower rotating support arm and the upper rotating support arm are rotated and closed and then retracted into the storage box on each assembled ballast water tank. After the upper and lower two assembled ballast water tanks are completely lowered, the bottom surface of the upper assembled ballast water tank and the top surface of the lower assembled ballast water tank are in contact with each other, which can reduce the stacking volume and facilitate the transfer of the engineering pile foundation to continue ballast testing or withdraw from the engineering pile foundation testing site.

The bottom of the end water bag guardrail and one or more lower hinges are fastened and movably connected to the panel of the end support plate. The top of the end water bag guardrail is fastened to the water bag lifting ring. When the end water bag guardrail is rotated and lifted by the lower hinges, the end of the water bag is lifted and stretched. When the end water bag guardrail is rotated and lifted to a vertical position, the interior of the water bag is lifted and stretched. The bottom of the end water bag guardrail is fastened to one or more lower hinges. The lower hinges rotate and support the end water bag guardrail. After the end water bag guardrail is rotated and lifted to a vertical position, it is at the same height as the side water bag guardrail.

The bottom ends of the upper rotating support arm and the lower rotating support arm are respectively fixedly connected to the respective corner parts of the assembled ballast water tank through the rotating shafts. When the rotating shaft components of two or more upper and lower assembled ballast water tanks respectively tightly nest and fixedly connect the concave or convex parts at the respective top ends of the upper rotating support arm and the lower rotating support arm, two or more mutually upper and lower assembled ballast water tanks can be connected to form a group of mutually stable connected ballast bodies.

[0020] Plug: It is made of hard material. The shape of the plug is a long strip cylindrical or square column shape. After the upper rotating support arm and the lower rotating support arm on multiple assembled ballast water tanks that are vertically movably connected to each other rotate around the rotating shaft member to a vertical state, the plug is installed in the plug hole, which can prevent the continuous rotation of the upper rotating support arm and the lower rotating support arm, so that the upper rotating support column and the lower rotating support column in a vertical state maintain a stable state perpendicular to each other up and down, enabling each assembled ballast water tank that is vertically movably connected to each other to form a stable ballast body after being lifted up and down. After the detection work is completed, the plug is removed from the plug hole, so that the upper rotating support arm and the lower rotating support arm on each assembled ballast water tank up and down can return to a rotatable state. Finally, the upper rotating support column and the lower rotating support column on each assembled ballast water tank are rotated and folded and retracted into each storage box.

The bottom end of the lifting device is fixedly set at the bottom end of the end panel. The top end of the tank lifting device is fastened to the bottom end of another assembled ballast water tank on the upper part. After the tank lifting devices of two or more assembled ballast water tanks on a group of ballast bodies are respectively connected to the bottom of their respective upper assembled ballast water tanks, a group can be formed. A stable ballast body. When the lifting device enters the working state, the lifting device on each lower assembled ballast water tank lifts the upper assembled ballast water tank to the rotation space height required for the upright support column. When the upright support column is rotated and upright to a vertical state, the support column fasteners are used to tightly nest and fasten the top of the upright support column and the bottom of the assembled ballast water tank to strengthen the overall safety factor of the upright support columns on each upper and lower assembled ballast water tanks of this group of ballast bodies after they are in a mutually vertical upright state and fastened together. After the work is completed, first drain the water in the water bags on the upper and lower assembled ballast water tanks, and then use a crane to slightly lift this group of ballast bodies from the bottom to the second assembled ballast water tank, so that the support column fasteners at the top of the upright support column and the bottom of the assembled ballast water tank are tightly nested and fastened to each other. The mutual force gripping state during the working state is relaxed, and after taking out the support column fasteners, the upright support column can be restored to the rotation state, and then the upright support column is rotated and stored in the storage box, and then the lifting device is lowered to make the height of the top surface of the lifting device consistent with the horizontal height of the end face guardrail, and then the end face water bag guardrail and the The side water bag guardrails, after the upper and lower assembled ballast water tanks of a group of ballast vehicles are completely lowered, the bottom surface of the upper assembled ballast water tank and the top surface of the lower assembled ballast water tank are in contact with each other, which can reduce the stacking and transportation volume of a group of ballast vehicles and facilitate the transportation and storage of each group of ballast vehicles; start the lifting devices on each assembled ballast water tank on this group of ballast vehicles from bottom to top, lower the upright support columns, the end water bag guardrails and the side water bag guardrails and the lifting devices respectively, and then lower each assembled ballast water tank, the bottom surface of each upper assembled ballast water tank and the top surface of the lower assembled ballast water tank are in contact with each other, and the ballasting work of this group of ballast vehicles is ended.

The height level of the top of the side water bag guardrail is consistent; then use the water pipe water supply method to inject any natural or tap water on the construction site into the water bag through the water bag water filling port, and seal the water bag water filling port after filling with water to form a relatively closed water load carrier. At this time, the end water bag guardrail surrounds the end face of the water bag, the side water bag guardrail surrounds the side of the water bag, and the water bag load-bearing plate supports the bottom surface of the water bag, which can further increase the safety factor of the water bag after filling with water. After the inspection work is completed, the water in the water bag is discharged through the drain port set at the bottom of the water bag, the water bag lifting ring on the top of the side water bag guardrail is removed, and the fastening connection between the top of the water bag and the side guardrail of the water bag is released. First, rotate and lower the end water bag guardrail. At this time, the water bag will be stored at the bottom of the end water bag guardrail, and then rotate and lower the side water bag guardrail.

[0026] Upper hinge: It is made of hard material. The upper hinge is a hinged rotating movable component. One to multiple upper hinges are fastened on the vertical vertical surface of the side support plate. The upper hinge is fastened and movably connected to the bottom end of the side water bag guardrail. The top ends of the bottom ends of the side water bag guardrails facing each other rotate in a circle with the upper hinge as the center. The upper hinge can support the entire weight of the side water bag guardrails. When entering the working state, the side water bag guardrails are first rotated and erected to a vertical upright state through the upper hinge, and then the end water bag guardrails are rotated and erected.

[0027] Lower hinge: It is made of hard material, and the upper hinge is a hinged rotating movable component. One to multiple lower hinges are fastened and arranged on the vertical vertical surface of the end support plate. The lower hinge is fastened and movably connected to the bottom end of the end water bag guardrail. The top ends of the bottom ends of the end water bag guardrails facing each other rotate in a circle with the lower hinge as the center. The lower hinge also supports the entire weight of the end water bag guardrail. When entering the working state, the side water bag guardrail is first rotated and erected to a vertical upright state through the upper hinge, and then the end water bag guardrail is rotated and erected.

[0028] Tank fasteners: They are made of hard material and are arranged on the tank end panels and the tank side panels. When two or more groups of ballast bodies are combined with each other up and down, left and right to form a comprehensive ballast body, the tank fasteners on each group of assembled ballast water tanks can be tightly fastened to each other up and down, left and right, thereby enhancing the overall safety factor of the two or more groups of ballast bodies after they are stacked together.

[0029] The first working mode of the assembled ballast water tank specially used for the ballast platform of engineering pile foundation inspection is: one or more assembled ballast water tanks form a group of ballast bodies. When entering the working state, the upright support columns at the end of the assembled ballast water tank at the top of this group of ballast bodies are first rotated from a horizontal state to a vertical state, and then the side water bag guardrails are rotated to a vertical state, and then the end water bag guardrails are rotated to a vertical state. When the end water bag guardrails are rotated upright, they support the end edges of the water bags, and then the multiple water bag lifting rings and the top ends of the side water bag guardrails are fastened together. At this time, the water bags on this assembled ballast water tank have been fully expanded, so that the water bags enter a working state waiting to be added to the water body.

[0030] Use a crane to lift the top assembled ballast water tank of this group of load carriers. When the first assembled ballast water tank from the top to the bottom is lifted by the crane, the upper rotating support arm connected to the bottom end of this assembled ballast water tank and the lower rotating support arm connected to the upper end of the second assembled ballast water tank from the top to the bottom will slowly rotate to a vertical upright state as the crane continues to lift. Then, the latch is installed in the latch hole, so that the upper rotating support arm and the lower rotating support arm in a vertical state can no longer rotate, thereby Maintaining a vertical and stable state, the side water bag guardrail on the second assembled ballast water tank from the top is rotated to an upright vertical state, and then the end water bag guardrail is rotated to an upright vertical state. The end water bag guardrail supports the upper end of the water bag when it is rotated upright, and multiple water bag lifting rings are used to fasten the upper side end of the water bag and the top of the side water bag guardrail. At this time, the water bag on this assembled ballast water tank has been fully expanded, so that the water bag enters a working state waiting to be added to the water body.

[0031] Continue to use the crane to lift the second assembled ballast water tank from top to bottom. When the second assembled ballast water tank from top to bottom is lifted by the crane, the upper rotating support arm connected to the bottom end of the second assembled ballast water tank and the lower rotating support arm at the upper end of the third assembled ballast water tank from top to bottom will slowly rotate to a vertical upright state as the crane continues to lift. Then, the latch is installed in the latch hole, so that the upper rotating support arm and the lower rotating support arm in a vertical state can no longer be rotated. Rotate to maintain a vertical and stable state, rotate the side water bag guardrail on the third assembled ballast water tank from the top to the bottom to an upright vertical state, and then rotate the end water bag guardrail to an upright vertical state. The end water bag guardrail supports the end of the water bag when it is rotated upright, and then fasten the multiple water bag lifting rings and the top of the side water bag guardrail to each other. At this time, the water bag on this assembled ballast water tank has been fully expanded, so that the water bag enters a working state waiting to be added to the water body.

[0032] Use a crane to lift this group of load-bearing bodies, which are connected to each other up and down, in sequence from top to bottom. After this group of ballast bodies enters the working state, use an external water pipe to add water to the water body through the water filling port on each water bag. After each water bag is filled with water, the water filling port is closed. The assembled ballast water tank uses the weight of the added water and its own weight to form a heavier comprehensive ballast body for static load detection test of the pile foundation.

[0033] After the inspection is completed, the water in each water bag on each assembled ballast water tank on this group of load-bearing vehicles will be discharged outwards first, and then the connection between each water bag lifting ring and the top of the side water bag guardrail will be released, and then each end water bag guardrail will be rotated and lowered. At this time, each water bag will be stored under the end water bag guardrail, and then the side water bag guardrail will be rotated and lowered.

[0034] Continue to use the crane to slightly lift the second assembled ballast water tank from the bottom up of this group of ballast carriers, so that the mutual force-gripping state of the upper rotating support arm, the lower rotating support arm, the pin and the rotating shaft member during the working state is relaxed, and then take out the pin from the pin hole. After taking out the pin from the pin hole, the upper rotating support arm and the lower rotating support arm can be restored to the rotatable state. Use the crane to slowly lower the second assembled ballast water tank from the bottom up. The upper rotating support arm and the lower rotating support arm on the first assembled ballast water tank from the bottom up and the second assembled ballast water tank from the bottom up will continue to rotate and close into the storage box as the crane continues to slowly lower. At this time, the upper surface of the box body of the first assembled ballast water tank from the bottom up and the bottom surface of the box body of the second assembled ballast water tank from the bottom up are in a state of being in contact with each other.

[0035] Then continue to use the crane to slightly lift the third assembled ballast water tank from the bottom up of this group of ballast carriers, so that the mutual force-gripping state of the upper rotating support arm, the lower rotating support arm, the pin and the rotating shaft member during the working state is relaxed to facilitate taking out the pin from the pin hole. After taking out the pin from the pin hole, the upper rotating support arm and the lower rotating support arm can be restored to the rotatable state. Then use the crane to slowly lower the third assembled ballast water tank from the bottom up. The upper rotating support arm and the lower rotating support arm on the third assembled ballast water tank from the bottom up and the second assembled ballast water tank from the bottom up will continue to rotate and close into the storage box as the crane continues to slowly lower. At this time, the upper surface of the box body of the second assembled ballast water tank from the bottom up and the bottom surface of the box body of the third assembled ballast water tank from the bottom up are in a state of being in contact with each other.

[0036] Use the crane to lower each of the assembled ballast water tanks that are vertically connected to each other on this group of ballast carriers in sequence, and then use the crane to lift one or more groups of assembled ballast water tanks off the engineering pile foundation ballast detection platform to complete the entire engineering pile foundation ballast detection work.

[0037] The second working mode of the assembled ballast water tank specially used for the ballast platform for engineering pile foundation inspection is: one or more assembled ballast water tanks form a group of ballast bodies. When entering the working state, first rotate the upright support columns at the end of the assembled ballast water tank at the top of this group of ballast bodies from a horizontal state to a vertical state, then rotate the side water bag guardrail to a vertical state, and then rotate the end water bag guardrail to a vertical state. The end water bag guardrail supports the end of the water bag when it is rotated upright, and then fasten the multiple water bag lifting rings and the top of the side water bag guardrail. At this time, the water bag on this assembled ballast water tank has been fully expanded, so that the water bag enters a working state waiting to be added to the water body.

[0038] Then start the lifting device on the second assembled ballast water tank from top to bottom. At this time, the two or more lifting devices on this assembled ballast water tank will slowly lift the box body of the other assembled ballast water tank above. When the lifting device lifts the upper assembled ballast water tank to a space range that allows the upright support column to rotate and stand upright, the upright support column can be rotated and stood upright to a vertical state. The top of the upright support column is provided with the support column fastener. The support column fastener at the top of the upright support column and the support column fastener at the bottom of the upright support column are tightly connected and nested with each other using fasteners, and then the lifting device is lowered. The upright support columns of each assembled ballast water tank above and below a group of ballast bodies are lifted by After rotating upright to a vertical state, the upper and lower parts can be combined to form a group of stable ballast bodies, and the side water bag guardrails on the second assembled ballast water tank from top to bottom are rotated to a vertical state, and then the end water bag guardrails are rotated to a vertical state. When the end water bag guardrails are rotated upright, they support the water bag so that it enters a working state waiting for water to be added. At this time, the support column fasteners at the top of each upright support column and the support column fasteners at the bottom of each upright support column are tightly connected and nested with each other, and then the lifting device on the second assembled ballast water tank from top to bottom is lowered. At this time, each of the upright supports on the second assembled ballast water tank from top to bottom will be able to independently support the entire weight of the first assembled ballast water tank from top to bottom.

[0039] Then start the lifting device on the third assembled ballast water tank from top to bottom. At this time, the two or more lifting devices on this assembled ballast water tank will slowly lift the box body of the other assembled ballast water tank above it. When the lifting device lifts the upper assembled ballast water tank to a space range that allows the upright support columns to be rotated and upright, two or more upright support columns can be rotated and upright to a vertical state. The top of the upright support column is provided with the support column fastener, and the support column fastener at the top of the upright support column and the support column fastener at the bottom of the upright support column are used to tightly connect and nest with each other. The upright support columns of each assembled ballast water tank above and below a group of ballast bodies are rotated and upright to a vertical state. After they are in the upright state and tightly connected, nested and fixed, they can be combined up and down to form a group of stable ballast bodies. The side water bag guardrail on the third assembled ballast water tank from top to bottom is rotated to a vertical state, and then the end water bag guardrail is rotated to a vertical state. When the end water bag guardrail is rotated upright, it supports the water bag so that it enters the working state waiting for water to be added. At this time, the support column fasteners at the top of each upright support column and the support column fasteners at the bottom of the upright support column are tightly connected, nested and fixed with each other, and then the lifting device on the third assembled ballast water tank from top to bottom is lowered. At this time, each of the upright supports on the third assembled ballast water tank from top to bottom will be able to independently support the entire weight of the second assembled ballast water tank from top to bottom.

[0040] Use a crane to lift this group of two or more assembled ballast water tanks connected to each other from top to bottom in sequence to put them into working condition, and then use an external water pipe to add water to the water body through the water filling port on each water bag. After each water bag is filled with water, the water filling port is closed. The weight of the added water and the weight of the water bag itself can be combined to form a heavier comprehensive ballast body for static load detection test of the pile foundation.

[0041] After the inspection work is completed, the water in each water bag on each assembled ballast water tank on this group of load-bearing vehicles will be discharged outwards first, and then the connection between each water bag lifting ring and the top of the side water bag guardrail will be released, and then the end water bag guardrails will be rotated and lowered. At this time, the water bag will be stored at the bottom of the end water bag guardrail, and then the side water bag guardrail will be rotated and lowered.

[0042] Then start the lifting device on the first prefabricated ballast water tank from bottom to top. The lifting device will slowly lift the second prefabricated ballast water tank body from bottom to top, so that the mutual force-gripping state between the support column fastener at the top of the vertical support column on the first prefabricated ballast water tank from bottom to top and the support column fastener at the bottom of the vertical support column on the second prefabricated ballast water tank body from bottom to top is relaxed to facilitate the removal of the support column fastener. After removing the support column fastener, the vertical support column can be restored to a rotatable state. Continuously and slowly rotate the vertical support column on the first prefabricated ballast water tank from bottom to top to a horizontal state until it is retracted into the storage box. Then lower the two or more lifting devices on this prefabricated ballast water tank. The height of the lifting device after lowering is the same as the horizontal height of the storage box. At this time, the upper surface of the box body of the first prefabricated ballast water tank from bottom to top and the bottom surface of the box body of the second prefabricated ballast water tank from bottom to top are in a state of being in contact with each other.

[0043] Then start the lifting device on the second prefabricated ballast water tank from bottom to top. The lifting device will slowly lift the third prefabricated ballast water tank body from bottom to top, so that the mutual force-gripping state between the support column fastener at the top of the vertical support column on the second prefabricated ballast water tank from bottom to top and the support column fastener at the bottom of the vertical support column on the third prefabricated ballast water tank body from bottom to top is relaxed to facilitate the removal of the support column fastener. After removing the support column fastener, the vertical support column can be restored to a rotatable state. Continuously and slowly rotate the vertical support column on the second prefabricated ballast water tank from bottom to top to a horizontal state until it is retracted into the storage box. Then lower the lifting device on this prefabricated ballast water tank. The height of the lifting device after lowering is the same as the horizontal height of the storage box. At this time, the upper surface of the box body of the second prefabricated ballast water tank from bottom to top and the bottom surface of the box body of the third prefabricated ballast water tank from bottom to top are in a state of being in contact with each other.

[0044] Lower the upper and lower prefabricated ballast water tanks on this group of ballast bodies from bottom to top in turn until all the prefabricated ballast water tanks on this group of ballast bodies are lowered. At this time, the upper surfaces and bottom surfaces of the box bodies of the prefabricated ballast water tanks on this group of ballast bodies are in a state of being in contact with each other, reducing the mutual stacking volume of the prefabricated ballast water tanks on this group of ballast bodies, facilitating the work of the crane. Then use the crane to lower the prefabricated ballast water tanks on this group of ballast bodies in turn, and then use the crane to lift one or more groups of prefabricated ballast water tanks off the engineering pile foundation ballast detection platform to complete the entire engineering pile foundation ballast detection work.

[0045] The present invention has at least the following beneficial effects:

[0046] The present invention tightly fastens two or more assembled ballast water tanks to each other vertically to form a ballast body, reducing the on-site assembly procedures and difficulty between the ballast water tanks, thus reducing the labor intensity, ensuring the overall structural strength of the ballast water tank and reducing the collapse risk. When in use, two or more groups of ballast bodies are stacked and connected to each other vertically, horizontally, and then water is added to jointly form a combined ballast body with a larger weight for static load testing of pile foundations. Since the box body and water are separated, users only need to transport and lift the box body, and can move this assembled ballast water tank arbitrarily, which is convenient for transportation, lifting, and storage, greatly improving work efficiency and economic efficiency.

[0047] The structure of the present invention is scientifically designed, easy to assemble and disassemble at the testing site, simple and convenient to operate, can replace the commonly used large concrete blocks at present, can significantly improve the work efficiency and safety of pile foundation static load testing, can greatly improve the work intensity during pile foundation static load testing, improve the safety requirements during the pile foundation static load testing process, and significantly reduce the cost expenditure of each component material during transportation and hoisting.

In the figure, only the folding and rotating support arm at one end is shown to facilitate the explanation of its working method. A group of ballast bodies is composed of more than one assembled ballast water tanks connected to each other up and down.

[0068] Figures 1 to 3 The present invention shows an embodiment of an assembled ballast water tank specifically used for a ballast platform for pile foundation inspection, comprising:

[0069] Several layers of ballast water tanks and support arm mechanisms supported between or on the ballast water tanks;

[0070] The ballast water tank has space for loading water, and the support arm mechanism is composed of several rotating support arms. Based on the rotational connection between the rotating support arms or between the rotating support arms and the ballast water tank, the support arm mechanism supports the ballast water tank when it rotates into an upright state, and the ballast water tank overlaps when the support arm mechanism rotates into a folded or lying state.

[0071] Specifically, refer to Figure 1, the illustrated structure is provided with three layers of ballast water tanks. The water is preferably arranged in the space of the ballast water tank in the form of a water bag water tank, etc. The support arm mechanisms of the uppermost layer of ballast water tanks are located at the four corners of the ballast water tank, and each support arm mechanism is configured as a single rotating support arm. The rotating support arm is connected to the box end face railing 4 through a rotating shaft to achieve rotation. At this time, the rotating support arm stands upright to form an upright support column 1. The rotating support arm can be laid down or folded into the storage box 5, and the storage box 5 is composed of the box end face railing 4 and the end face support plate 35.

[0072] Between the uppermost layer of ballast water tank and the middle layer of ballast water tank (or above the middle layer of ballast water tank), and between the middle layer of ballast water tank and the lowermost layer of ballast water tank (or above the lowermost layer of ballast water tank), a structure in which the upper rotating support arm 32 and the lower rotating support arm 33 are rotatably connected (that is, composed of two rotating support arms) is provided. The bottom end of the upper rotating support arm 32 is connected to the box end face railing 4 through a rotating shaft 9 to achieve rotation, and the lower rotating support arm 33 is also connected to the lower box end face railing 4 through the rotating shaft 9 to achieve rotation. The upper rotating support arm 32 and the lower rotating support arm 33 are rotatably connected through a rotating shaft member 34 and are equipped with a bolt to maintain the upright state of the upper and lower rotating support arms. When the number of rotating support arms is greater than two, the structure setting is similar to that of the above-mentioned upper rotating support arm 32 and lower rotating support arm 33, and those skilled in the art can understand and implement it with reference to the above description.

[0073] Reference Figure 2 , the illustrated structure is provided with three layers of ballast water tanks, and Figure 1 differently, the support arm mechanism of each layer of ballast water tank is configured as a single rotating support arm. Figure 2 In the shown state, the rotating support arms all stand upright to form upright support columns 1, and the corresponding rotational connection manner of the rotating support arms is Figure 1 similar to the shown structure, and can be understood with reference to the above Figure 1 description.

[0074] Reference Figure 3 , the illustrated structure is a one-layer ballast water tank structure, and the support arm mechanism of the ballast water tank is configured as a single rotating support arm. At this time, the rotating support arm stands upright to form an upright support column 1.

[0075] Whether it is Figure 1 or Figure 2 the shown structure, after the rotating support arm rotates into the storage box, each layer of ballast water tank can be stacked and tightened to reduce the volume.

[0076] Furthermore, in another embodiment, as Figures 2 to 5As shown, a support column fastener 2 is internally or externally fitted to the rotary support arm. When the support arm mechanism is in an upright state, the support column fastener joins or bridges several rotary support arms into a stable upright support column 1, or joins or bridges the upright support columns 1 of the upper and lower ballast tanks together. As required, the support column fastener 2 can be set as a pin structure, rod structure, sheet structure, tubular shape, etc.

[0077] For specific reference Figure 2 for understanding, Figure 2 In the figure, the support column fastener 2 is installed at the center of the upright support column 1. While ensuring the structural strength of the upright support column, it is also convenient for plug-in cooperation. After the support column fastener 2 is inserted into the upright support column 1, it can prevent the upright support column 1 from rotating. When the upright support column 1 is composed of two or more rotary support arms, it can prevent the rotary support arms from rotating and folding, and thus can maintain the upright state of the upright support column 1.

[0078] The support column fastener 2 can also be fitted outside the upright support column 1. Just like bone fracture bridging and repair, a protective structure is lapped on the upright support column 1 to prevent the upright support column 1 from rotating or breaking.

[0079] Furthermore, in another embodiment, as Figures 2 to 5 shown, when the support column fastener 2 is fitted inside the rotary support arm, a fitting hole is provided inside the rotary support arm. The support column fastener 2 accesses the fitting holes of two adjacent rotary support arms to complete joining or bridging; specifically, the fitting hole can penetrate the entire rotary support arm, and at this time the support column fastener 2 can be entirely inserted into the fitting hole to join two rotary support arms; the fitting hole can also be only provided at both ends of the rotary support arm, and both ends of the support column fastener 2 are respectively inserted into the fitting holes of two adjacent rotary support arms. These designs can all fasten the upright support column 1 to prevent the upright support column 1 from lodging, deflecting, and breaking.

[0080] When the support column fastener 2 is fitted outside the rotary support arm, a fitting groove is provided or not provided on the outer wall of the rotary support arm. The support column fastener 2 is embedded or not embedded in the fitting groove to join or bridge two adjacent rotary support arms. Specifically, when no fitting groove is provided, the support column fastener 2 can be directly lapped outside the rotary support arm.

[0081] Furthermore, in another embodiment, the construction method of the storage box 5 refers to Figures 1 to 7, the railing plates (i.e., the side railing plate 3 and the end railing plate 4 of the box body) provided at the end face of the ballast water tank enclose the end of the ballast water tank into a storage box 5 with an upward opening, and the support arm mechanism is incorporated into the storage box 5 when folded or laid down. More specifically, the storage box 5 is actually formed by enclosing the side railing plate 3 or the end railing plate 4 of the box body and the inner support plates (including the side support plate 6 and the end support plate 35). According to needs, the storage box can be set for different purposes, such as storing the rotary support arm, forming a buffer cavity, serving as a toolbox, etc.

[0082] Further, in another embodiment, referring to Figure 2 , a support column booster rod 15 is connected between the storage box 5 and the support arm mechanism, and the support arm mechanism can be supported or laid down through the support column booster rod 15.

[0083] Further, in another embodiment, as Figure 1 and 8 shown, when the support arm mechanism is composed of two rotary support arms, the top end of the upper rotary support arm 32 is rotatably connected to the upper layer ballast water tank through a rotating shaft 9, the top end of the lower rotary support arm 33 is rotatably connected to the lower layer ballast water tank through a rotating shaft 9, the upper rotary support arm 32 and the lower rotary support arm 33 are rotatably connected through a rotating shaft member 34 and are respectively provided with pin holes 31. When the upper rotary support arm and the lower rotary support arm rotate to the upright state, the two pin holes correspond to each other, and the pin holes 31 cooperate with the pins 30 to keep the upper rotary support arm 32 and the lower rotary support arm 33 upright.

[0084] Further, in another embodiment, referring to Figures 2 to 8 , the space for loading water in the ballast water tank is at least enclosed by four water bag railing plates (including two end face water bag railing plates 21 and two side water bag railing plates 22). The water bag railing plates are set as a structure that can be flipped. When the water bag railing plates are upright, they form the space for loading water. When flipped to the horizontal, the water bag railing plates are flipped into the space for loading water to complete stacking (refer to Figures 3 to 5 to see the stacking state of the water bag railing plates);

[0085] As Figure 4 shown, a rod-plate fastener 23 provided between the support arm mechanism and the water bag railing plate forms a fixation for the water bag railing plate to maintain the upright state of the water bag railing plate;

[0086] To support the flipping of the water bag railing plates, a support plate (including the side support plate 6 and the end support plate 35) is provided under each water bag railing plate. The water bag railing plate and the support plate are hinged through hinges (including the upper hinge 13 and the lower hinge 14) to realize the flip of the water bag railing plate; the number of hinges is set according to needs.

[0087] As Figure 5 , 6As shown in Figures 6 and 7, the bottom of the space for loading water is configured as a water bag load-bearing plate 19. A water bag 10 or a water tank, etc. is placed inside the space for loading water, and water can be filled through the water bag water filling port 20 to become a load counterweight.

[0088] As Figure 3 and 4 shown, the water bag 10 is fixed or not fixed to the inner wall of the ballast water tank; when it is set to be fixed, water bag hanging rings 11 and water bag fasteners 12 are provided on the inner wall of the water bag railing. The water bag hanging rings 11 are connected to the water bag 10, and the water bag fasteners 12 fasten the water bag from above, or the water bag hanging rings 11 are connected to the water bag fasteners 12, and the water bag fasteners are connected to the water bag railing, so that the water bag 10 is pulled and fixed.

[0089] Furthermore, in another embodiment, as Figure 2 shown, a lifting device 16 or a lifting tool 17 or a combination of both is provided at the side end of the ballast water tank to assist the support arm mechanism to stand upright;

[0090] The lifting device 16 is an electric telescopic rod, a threaded screw rod, a pneumatic telescopic rod, a hydraulic telescopic rod, etc. The lifting device 16 supports the ballast water tank to be lifted or stacked;

[0091] When the lifting device 16 is set as a hydraulic telescopic rod, the hydraulic chamber or compression chamber of the hydraulic telescopic rod is connected to the water bag 10 through a valve body. When the hydraulic telescopic rod works, the hydraulic chamber is injected with a hydraulic medium to make the hydraulic telescopic rod extend, and part of the hydraulic medium such as water can enter the water bag through the valve body, so that the water bag continuously flushes and expands to support the upper ballast water tank. The valve body can be a pressure relief valve, a constant pressure valve, etc. The hydraulic pump of the hydraulic telescopic rod pumps water into the water bag. Part of the water provides the telescopic support of the hydraulic telescopic rod, and part of the water enters the water bag.

[0092] The lifting tool 17 is a straight rod, a straight cylinder or a straight plate, and is vertically fitted at the side end of the multi-layer ballast water tank. For example, it is vertically inserted into the storage box or outside the storage box, and is in sliding fit with each layer of the ballast water tank (such as through a cylinder, a chute, etc.). Under the limiting action of the lifting tool, each layer of the ballast water tank can only be vertically lifted and lowered along the lifting tool, avoiding the position deviation of each layer of the ballast water tank during lifting and lowering, which may cause the upright support column 1 to be misaligned. In addition, when the lifting tool 17 is set as a straight cylinder, the lifting device (electric telescopic rod or hydraulic telescopic rod) can be directly sleeved inside, so that the lifting device can vertically expand and contract. The combination of the two is easier to ensure the vertical lifting and lowering of the ballast water tank to complete the lifting and stacking of the ballast water tank.

[0093] Furthermore, in another embodiment, refer to Figures 1 to 7, a receiving space is formed between the support plate (including the side support plate 6 and the end face support plate 35) and the side rail (such as the side box rail 3) and the end face rail (such as the end face box rail 4) arranged around the ballast water tank; the receiving space is used for the folding or toppling support arm mechanism to form a storage box 5 (refer to Figure 3 ), or for storing tools to form a tool storage box 36 (refer to Figure 7 ), or for not storing anything to form a buffer cavity (refer to Figure 7 ). The upper end face of the buffer space is closed by a panel 8, and both side edges of the panel 8 support the support plate and the rail respectively. Box fasteners 18 are provided on the side rails (including the side box rail 3 and the end face box rail 4) to fix or reinforce the tight connection of each assembled ballast water tank in the vertical and horizontal directions.

[0094] The first method for engineering pile foundation detection using the assembled ballast water tank includes:

[0095] Form a set of ballast bodies with one or more of the assembled ballast water tanks;

[0096] When the support arm mechanism is composed of two or more rotating support arms, first stand up the support arm mechanism of the uppermost ballast water tank in a set of ballast bodies to support the water loading space, then lift the uppermost ballast water tank, so that the support arm mechanisms of the lower layers of ballast water tanks stand up in turn, tighten the support arm mechanisms after standing up in turn, and finally add water to the water bag to increase the weight of the ballast body;

[0097] Finally, several sets of ballast bodies form a comprehensive ballast body to conduct a static load test on the pile foundation.

[0098] The second method for engineering pile foundation detection using the assembled ballast water tank includes:

[0099] Form a set of ballast bodies with one or more of the assembled ballast water tanks;

[0100] When the support arm mechanism is composed of two or more rotating support arms, lift each ballast water tank layer of a set of ballast bodies from top to bottom in turn, so that the support arm mechanisms of each layer of ballast water tanks stand up in turn, tighten the support arm mechanisms after standing up in turn, and finally add water to the water bag to increase the weight of the ballast body;

[0101] Finally, several sets of ballast bodies form a comprehensive ballast body to conduct a static load test on the pile foundation.

[0102] The third method for engineering pile foundation detection using the assembled ballast water tank includes:

[0103] Form a set of ballast bodies with one or more of the assembled ballast water tanks;

[0104] The lifting device is used to sequentially prop up the support arm mechanism of each layer of ballast tank from bottom to top until it is upright, and water is simultaneously added to the water bag of the corresponding layer of ballast tank; the upper bag is equipped with a supporting mechanism, and the water bag is expanded to make the supporting mechanism rise above the railing to form support for the upper ballast water tank and assist the support arm mechanism to stand upright;

[0105] Finally, several groups of ballast bodies are combined to form a comprehensive ballast body to carry out static load detection tests on the pile foundation.

[0106] The implementation process of the assembled ballast water tank specially used for the ballast platform of engineering pile foundation inspection in this case is as follows:

[0107] The assembled ballast water tanks are pre-produced and processed in the factory, and then two or more assembled ballast water tanks are selected to be connected to a group of ballast bodies at the top and bottom, and then arrive at the pile foundation inspection site. According to the load requirements of the pile foundation ballast inspection, a crane is used to lift one or more groups of ballast bodies to the ballast inspection platform. After each group of ballast bodies enters the working state, the water obtained at the construction site is injected into each of the water bags using an external water pipe supply method. After each water bag is filled with water, the water filling port is closed. The weight of the added water and the weight of the tank itself can be combined to form a heavier comprehensive ballast body for static load inspection test of the pile foundation.

[0108] After the inspection work is completed, the water in the water bags on each assembled ballast water tank on each group of ballast bodies is first discharged outward, and then the connection between each water bag lifting ring or the water bag fastener and the top of the side water bag guardrail is released, and then each end water bag guardrail is rotated and lowered. At this time, each water bag will shrink and be stored under the end water bag guardrail, and then each side water bag guardrail is rotated and lowered.

[0109] 1. If you choose to use a lifting device to lift each assembled ballast water tank, the specific steps include: one or more assembled ballast water tanks form a group of ballast bodies. When entering the working state, first rotate the upright support columns at the end of the uppermost assembled ballast water tank of this group of ballast bodies from a horizontal state to a vertical state, then rotate the side water bag guardrails to a vertical state, and then rotate the end water bag guardrails to a vertical state. When the end water bag guardrails are rotated upright, they support the ends of the water bags. Then, multiple water bag lifting rings are fastened to the tops of the side water bag guardrails. At this time, the water bags on this assembled ballast water tank have been fully expanded, so that the water bags enter a working state waiting to be added to the water body.

[0110] Then start the lifting device on the second assembled ballast water tank from top to bottom. At this time, the two or more lifting devices on this assembled ballast water tank will slowly lift the box body of the other assembled ballast water tank above. When the lifting device lifts the upper assembled ballast water tank to the space range that allows the upright support column to rotate and stand upright, the upright support column can be rotated and stood upright to a vertical state. The top of the upright support column is provided with the support column fastener. The support column fastener at the top of the upright support column and the support column fastener at the bottom of the upright support column are tightly connected and nested with each other using fasteners, and then the lifting device is lowered. A group of upright support columns of each assembled ballast water tank above and below the ballast body are lifted. After being rotated upright to a vertical state, they can be combined up and down to form a group of stable ballast bodies, and the side water bag guardrail on the second assembled ballast water tank from top to bottom is rotated to a vertical state, and then the end water bag guardrail is rotated to a vertical state. When the end water bag guardrail is rotated upright, it supports the water bag so that it enters a working state waiting for water to be added. At this time, the support column fasteners at the top of each upright support column and the support column fasteners at the bottom of the upright support column are tightly connected and nested with each other, and then the lifting device on the second assembled ballast water tank from top to bottom is lowered. At this time, each of the upright supports on the second assembled ballast water tank from top to bottom will be able to independently support the entire weight of the first assembled ballast water tank from top to bottom.

[0111] Then start the lifting device on the third assembled ballast water tank from top to bottom. At this time, the two or more lifting devices on this assembled ballast water tank will slowly lift the box body of the other assembled ballast water tank on the top. When the lifting device lifts the upper assembled ballast water tank to a space range that allows the upright support columns to be rotated and upright, two or more upright support columns can be rotated and upright to a vertical state. The top of the upright support column is provided with the support column fastener, and the support column fastener at the top of the upright support column and the support column fastener at the bottom of the upright support column are used to tightly connect and nest with each other. The upright support columns of each assembled ballast water tank above and below a group of ballast bodies are rotated and upright to After being in a vertical state and tightly connected, nested and fixed, they can be combined up and down to form a group of stable ballast bodies. The side water bag guardrail on the third assembled ballast water tank from top to bottom is rotated to a vertical state, and then the end water bag guardrail is rotated to a vertical state. When the end water bag guardrail is rotated upright, it supports the water bag so that it enters a working state waiting for water to be added. At this time, the support column fasteners at the top of each upright support column and the support column fasteners at the bottom of the upright support column are tightly connected, nested and fixed to each other, and then the lifting device on the third assembled ballast water tank from top to bottom is lowered. At this time, each of the upright supports on the third assembled ballast water tank from top to bottom will be able to independently support the entire weight of the second assembled ballast water tank from top to bottom.

[0112] Use a crane to lift this group of two or more assembled ballast water tanks connected to each other from top to bottom in sequence to put them into working condition, and then use an external water pipe to add water to the water body through the water filling port on each water bag. After each water bag is filled with water, the water filling port is closed. The weight of the added water and the weight of the water bag itself can be combined to form a heavier comprehensive ballast body for static load detection test of the pile foundation.

[0113] After the inspection work is completed, the water in each water bag on each assembled ballast water tank on this group of load-bearing vehicles is first discharged outward, and then the connection between the water bag lifting ring and the top of the side water bag guardrail is released, and then the end water bag guardrails are rotated and lowered. At this time, each water bag will be stored under the end water bag guardrail, and then the side water bag guardrails are rotated and lowered again.

[0114] First, start the lifting device on the first prefabricated ballast water tank from bottom to top. The lifting device will slowly lift the second prefabricated ballast water tank body from bottom to top, so that the mutual force-gripping state between the support column fastener at the top of the vertical support column on the first prefabricated ballast water tank from bottom to top and the support column fastener at the bottom of the vertical support column on the second prefabricated ballast water tank body from bottom to top is relaxed, facilitating the removal of the support column fastener. After removing the support column fastener, the vertical support column can be restored to a rotatable state. Continuously and slowly rotate the vertical support column on the first prefabricated ballast water tank from bottom to top to the horizontal state until it is retracted into the storage box. Then, lower the two or more lifting devices on this prefabricated ballast water tank. The height of the lifting device after lowering is the same as the height of the storage box. At this time, the upper surface of the box body of the first prefabricated ballast water tank from bottom to top and the bottom surface of the box body of the second prefabricated ballast water tank from bottom to top are in a state of mutual abutment.

[0115] Then, start the lifting device on the second prefabricated ballast water tank from bottom to top. The lifting device will slowly lift the third prefabricated ballast water tank body from bottom to top, so that the mutual force-gripping state between the support column fastener at the top of the vertical support column on the second prefabricated ballast water tank from bottom to top and the support column fastener at the bottom of the vertical support column on the third prefabricated ballast water tank body from bottom to top is relaxed, facilitating the removal of the support column fastener. After removing the support column fastener, the vertical support column can be restored to a rotatable state. Continuously and slowly rotate the vertical support column on the second prefabricated ballast water tank from bottom to top to the horizontal state until it is retracted into the storage box. Then, lower the lifting device on this prefabricated ballast water tank. The height of the lifting device after lowering is the same as the height of the storage box. At this time, the upper surface of the box body of the second prefabricated ballast water tank from bottom to top and the bottom surface of the box body of the third prefabricated ballast water tank from bottom to top are in a state of mutual abutment.

[0116] Lower the upper and lower prefabricated ballast water tanks on this group of ballast bodies from bottom to top in sequence until all the prefabricated ballast water tanks on this group of ballast bodies are lowered. At this time, the upper surfaces and bottom surfaces of the box bodies of the prefabricated ballast water tanks on this group of ballast bodies are in a state of mutual abutment, reducing the mutual stacking volume of the prefabricated ballast water tanks on this group of ballast bodies and facilitating the crane operation.

[0117] Use the crane to lower the prefabricated ballast water tanks on this group of ballast bodies in sequence, and then use the crane to lift one or more groups of prefabricated ballast water tanks off the engineering pile foundation ballast detection platform to complete the entire engineering pile foundation ballast detection work.

[0118] Another implementation process of the assembled ballast water tank specially used for the ballast platform of engineering pile foundation inspection in this case is as follows:

[0119] If you choose to use a rotating support arm to lift each assembled ballast water tank, the specific steps include: one or more assembled ballast water tanks form a group of ballast bodies. When entering the working state, first rotate the each upright support column at the end of the assembled ballast water tank at the top of this group of ballast bodies from a horizontal state to a vertical state, then rotate the side water bag guardrail to a vertical state, and then rotate the end water bag guardrail to a vertical state. The end water bag guardrail supports the end edge of the water bag when it is rotated upright, and then fasten the multiple water bag lifting rings and the top of the side water bag guardrail. At this time, the water bag on this assembled ballast water tank has been fully expanded, so that the water bag enters a working state waiting to be added to the water body.

[0120] Use a crane to lift the top assembled ballast water tank of this group of load carriers. When the first assembled ballast water tank from the top to the bottom is lifted by the crane, the upper rotating support arm connected to the bottom end of the first assembled ballast water tank and the lower rotating support arm connected to the upper end of the second assembled ballast water tank from the top to the bottom will slowly rotate to a vertical upright state as the crane continues to lift. Then, the latch is installed in the latch hole, so that the upper rotating support arm and the lower rotating support arm in a vertical state can no longer rotate, thereby Maintaining a vertical and stable state, the side water bag guardrail on the second assembled ballast water tank from the top is rotated to an upright vertical state, and then the end water bag guardrail is rotated to an upright vertical state. The end water bag guardrail supports the upper end of the water bag when it is rotated upright, and multiple water bag lifting rings are used to fasten the upper side end of the water bag and the top of the side water bag guardrail. At this time, the water bag on this assembled ballast water tank has been fully expanded, so that the water bag enters a working state waiting to be added to the water body.

[0121] Continue to use the crane to lift the second assembled ballast water tank from top to bottom. When the second assembled ballast water tank from top to bottom is lifted by the crane, the upper rotating support arm connected to the bottom end of the second assembled ballast water tank and the lower rotating support arm at the upper end of the third assembled ballast water tank from top to bottom will slowly rotate to a vertical upright state as the crane continues to lift. Then, the latch is installed in the latch hole, so that the upper rotating support arm and the lower rotating support arm in a vertical state can no longer be rotated. Rotate to maintain a vertical and stable state, rotate the side water bag guardrail on the third assembled ballast water tank from the top to the bottom to an upright vertical state, and then rotate the end water bag guardrail to an upright vertical state. The end water bag guardrail supports the end of the water bag when it is rotated upright, and then fasten the multiple water bag lifting rings and the top of the side water bag guardrail to each other. At this time, the water bag on this assembled ballast water tank has been fully expanded, so that the water bag enters a working state waiting to be added to the water body.

[0122] Use a crane to lift this group of load-bearing bodies, which are connected to each other up and down, in sequence from top to bottom. After this group of ballast bodies enters the working state, use an external water pipe to add water to the water body through the water filling port on each water bag. After each water bag is filled with water, the water filling port is closed. The assembled ballast water tank uses the weight of the added water and its own weight to form a heavier comprehensive ballast body for static load detection test of the pile foundation.

[0123] After the inspection is completed, the water in each water bag on each assembled ballast water tank on this group of load-bearing vehicles will be discharged outwards first, and then the connection between each water bag lifting ring and the top of the side water bag guardrail will be released, and then each end water bag guardrail will be rotated and lowered. At this time, each water bag will be stored under the end water bag guardrail, and then the side water bag guardrail will be rotated and lowered.

[0124] Continue to use the crane to slightly lift this group of ballast bodies from the bottom to the second assembled ballast water tank, so that the upper rotating support arm, the lower rotating support arm, the latch and the rotating shaft component are relaxed in the mutual force and tight grip state in the working state, and then remove the latch from the latch hole. After the latch is removed from the latch hole, the upper rotating support arm and the lower rotating support arm can be restored to the rotating state, and the crane is used to slowly lower the second assembled ballast water tank from the bottom to the top. The upper rotating support arm and the lower rotating support arm on the first assembled ballast water tank from the bottom to the top and the second assembled ballast water tank from the bottom to the top will continue to rotate and close by themselves as the crane continues to slowly lower. The storage box will be stored in the storage box. At this time, the upper surface of the box body of the first assembled ballast water tank from the bottom to the top and the bottom surface of the box body of the second assembled ballast water tank from the bottom to the top are in contact with each other.

[0125] Continue to use the crane to slightly lift the third assembled ballast water tank from the bottom up of this group of ballast carriers, so that the mutual force-gripping state of the upper rotating support arm, the lower rotating support arm, the pin and the rotating shaft member during the working state is relaxed to facilitate the removal of the pin from the pin hole. After removing the pin from the pin hole, the upper rotating support arm and the lower rotating support arm can be restored to the rotatable state. Then use the crane to slowly lower the third assembled ballast water tank from the bottom up. The upper rotating support arm and the lower rotating support arm on the third assembled ballast water tank from the bottom up and the second assembled ballast water tank from the bottom up will continue to rotate and close into the storage box with the continuous slow lowering action of the crane. At this time, the upper surface of the box body of the second assembled ballast water tank from the bottom up and the bottom surface of the box body of the third assembled ballast water tank from the bottom up are in a state of being in contact with each other.

[0126] Use the crane to lower each of the assembled ballast water tanks that are vertically connected up and down in this group of ballast carriers in sequence, and then use the crane to lift one or more groups of assembled ballast water tanks off the engineering pile foundation ballast detection platform to complete the entire engineering pile foundation ballast detection work.

[0127] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved.
