Description

Technical Field

[0001] This application relates to the field of building foundation pit engineering technology, and in particular to a recyclable prefabricated water-stop curtain system. Background Technology

[0002] Because groundwater can easily seep into the foundation pit during excavation and construction, affecting the construction, it is necessary to isolate the groundwater outside the foundation pit area. The traditional construction method is to install water-stop piles during the foundation pit support process. Water-stop piles usually come in the form of cement mixing piles and high-pressure jet grouting piles. After the water-stop piles are installed and meet the strength requirements, the foundation pit construction can continue.

[0003] However, the above methods have certain requirements on the soil quality of the construction site. If the construction site is a sandy soil, the water-stop pile is not easy to form. Moreover, water-stop piles are prone to leakage problems in the later stage, and it is difficult to plug the leaks. Therefore, this application proposes a new technical solution. Summary of the Invention

[0004] To improve the quality of water-stopping and ease of construction, this application provides a recyclable prefabricated water-stopping curtain system.

[0005] This application provides a recyclable prefabricated waterproof curtain system, which adopts the following technical solution:

[0006] A recyclable prefabricated waterstop curtain system includes multiple waterstop plates. Each waterstop plate includes two frames, multiple ribs, and multiple waterproof membranes. The multiple ribs are distributed along the length of the frames and connect the two frames. The waterproof membranes are installed between the cavities of the frames and the ribs. The side walls of the frames are provided with snap-fit ​​structures for connecting the multiple waterstop plates. The snap-fit ​​structures include buckles and snap-fit ​​connectors. The buckles and snap-fit ​​connectors are respectively fixed to the side walls of the two frames away from the ribs. The buckles snap into the snap-fit ​​connectors of adjacent waterstop plates.

[0007] The bottom of the waterstop plate is provided with a cutter head structure, the bottom of the cutter head structure is set with a slope, the thickness of the cutter head structure is greater than that of the rib plate, and a pile driver is slidably connected between the two frame plates, the bottom of the pile driver abutting against the cutter head structure.

[0008] Optionally, it also includes a guiding mechanism for assisting in the installation of the waterstop plate and a positioning mechanism for connecting the guiding mechanism and guiding it to change the construction area. The guiding mechanism includes a guiding plate, a connecting rod, and a moving trolley for changing the construction area. The two ends of the connecting rod are respectively installed on the guiding plate and the moving trolley and connect the guiding plate and the moving trolley. The waterstop plate passes through the space between the guiding plate and the moving trolley. The moving trolley is slidably connected to the positioning mechanism.

[0009] Optionally, the positioning mechanism includes positioning posts and steel cables. There are at least two positioning posts, each installed at one end of a certain edge of the pit. At least the lower half of each positioning post has a helical blade, the outer diameter of which is equal to the diameter of the upper half of the positioning post. A support block is threaded onto the outer side of the upper half of the positioning post. An I-beam wheel is rotatably connected to the side wall of the support block, with the rotation surfaces of the I-beam wheel and the support block perpendicular to the ground. A slot is provided at the top of the positioning post. After the I-beam wheel is rotatably installed onto the top of the support block, a rod is inserted through the center of the I-beam wheel, extending out of the wheel and into the slot. The steel cable wraps around the middle section of the I-beam wheel, with a fixing buckle at one end. At least one I-beam wheel is equipped with a pull ring for connecting the fixing buckle.

[0010] Optionally, the mobile trolley includes a connecting seat and a base distributed vertically, with multiple springs and multiple telescopic rods vertically installed between the connecting seat and the base, and the steel cable passing through the top of the connecting seat.

[0011] Optionally, a locking plate is provided between the guide plate and the adjacent waterstop plate. The guide plate has a slot for inserting the locking plate. One end of the locking plate is inserted into the slot, and the other end extends towards the side wall of the pit and then bends downward. The end of the locking plate abuts against the side wall of the adjacent waterstop plate away from the guide plate. The side wall of the slot is provided with a locking assembly for fixing the locking plate.

[0012] Optionally, the locking assembly includes an abutment plate and a corrugated pipe fixed between the abutment plate and the side wall of the slot. The side wall of the slot is provided with a water filling groove, and a water pump is connected to the water filling groove through a water pipe.

[0013] Optionally, the bottom of the slot is provided with a water filling button for controlling the water pump to fill water. When the water filling button is not triggered, it protrudes from the bottom of the slot and is electrically connected to the water pump.

[0014] The abutment plate is embedded with a pressure sensor with the detection end of the pressure sensor facing the inside of the slot. The pressure sensor is electrically connected to a controller, which is also electrically connected to a water pump. The controller is configured to control the water pump to stop filling water if the feedback value received from the pressure sensor is greater than P. Here, P is a preset pressure value fed back by the pressure sensor when the abutment plate is sufficiently locked.

[0015] Optionally, the pile driver has multiple ranging holes, and these holes are distributed in at most half of the total length of the pile driver. The multiple ranging holes are distributed along the length of the pile driver, and their spacing decreases from the middle to the end. A laser ranging sensor is embedded in the side wall of the base facing the pile driver, and the detection end of the laser ranging sensor faces the pile driver. The laser ranging sensor is electrically connected to the controller, and the controller is wirelessly connected to the display unit of the pile driving equipment used to drive the pile driver.

[0026] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0027] This application discloses a recyclable prefabricated waterproof curtain system.

[0028] Reference Figure 1 and Figure 2 The recyclable prefabricated waterstop curtain system includes multiple waterstop plates 1. Each waterstop plate 1 includes two frames 11, multiple ribs 12, and multiple waterproof membranes 13. The frames 11 are elongated when viewed from above. The multiple ribs 12 are distributed along the length of the frames 11 and connect the two frames 11. That is, the two frames 11 are placed in parallel, and the multiple ribs 12 are distributed in parallel between the two frames 11. The two ends of the ribs 12 are respectively connected to the two frames 11, and the ribs 12 and the frames 11 are vertically connected.

[0029] Multiple ribs 12 and frame 11 enclose multiple cavities, and a waterproof membrane 13 is installed in the cavity. The waterproof membrane 13 may be bonded to the sidewalls of the ribs 12 and frame 11.

[0030] Reference Figure 2 and Figure 3 The sidewall of the frame 11 is provided with a snap-fit ​​structure for connecting multiple waterstop plates 1. The snap-fit ​​structure includes a buckle 14 and a snap-fit ​​connector 15. The buckle 14 and the snap-fit ​​connector 15 are respectively fixed to the sidewall of the two frames 11 away from the rib plate 12, so as to facilitate the connection of two adjacent frames 11 through the buckle 14 and the snap-fit ​​connector 15. The shape of the buckle 14 and the snap-fit ​​connector 15 includes, but is not limited to, the snap-fit ​​connector 15 being circular when viewed from above, the buckle 14 being C-shaped, or the snap-fit ​​connector 15 being triangular when viewed from above, with the buckle 14 fitting into the triangular shape. This application takes the circular snap-fit ​​connector 15 and the C-shaped buckle 14 as examples.

[0031] The bottom of the waterstop plate 1 is provided with a cutter head structure 16. The bottom of the cutter head structure 16 is set at an angle, that is, when viewed from the side, the upper half of the cutter head structure 16 is rectangular and the lower half is triangular, which facilitates the insertion of the cutter head into the soil. The thickness of at least the upper half of the cutter head structure 16 is greater than that of the rib plate 12. A pile driver 4 is slidably connected between the two frame plates 11. The bottom of the pile driver 4 abuts against the top of the cutter head structure 16. The pile driver 4 can be I-shaped when viewed from above. One horizontal section is longer than the other section, which is used to slide between the two frame plates 11. The part of this section near both ends extends vertically with protrusions to abut against the bottom cutter head structure 16. When the frame plate 11 needs to be hammered into the soil after the pile driver 4 is inserted, the protrusions connect to the vertical part of the I-shaped structure to increase the force-bearing area and further push the frame plate 11 into the soil.

[0032] In this embodiment, the above-mentioned device is used as follows:

[0033] In this embodiment, a pile driver is used for construction, and a vibratory hammer is installed on the pile driver. The vibratory hammer and the pile driver 4 are pre-connected.

[0034] First, the pile driver 4 and multiple waterstop plates 1 are transported to the construction site. Multiple waterstop plates 1 transported to the site are unloaded around the foundation pit using a truck crane or tower crane. One of the waterstop plates 1 is placed on the construction platform. With the help of the staff, the pile driver 4 is inserted into the waterstop plate 1, so that the bottom of the pile driver 4 abuts against the top of the cutter head structure 16.

[0035] Subsequently, the pile driver is controlled to raise its boom, and the connected waterstop plate 1 and pile driver 4 are aligned with the construction area. The vibratory hammer is then opened, the waterstop plate 1 is lowered and hammered, and the waterstop plate 1 is gradually pressed into the soil.

[0036] Then, after the waterstop plate 1 is pressed down to the preset height position, the staff controls the pile driver to pull up the pile driver 4;

[0037] Finally, move to the next construction area and repeat the above steps to connect the waterstop 1 in sequence, eventually forming a continuous waterstop curtain.

[0038] With the above-described configuration, multiple waterstop plates 1 are connected by snap-fit ​​fasteners 14 and snap-fit ​​connectors 15, simplifying the installation process. The blade structure 16 at the bottom of the waterstop plate 1 minimizes the impact on installation, even in sandy or other soil conditions. The installation of the waterproof membrane 13 on the waterstop plate 1 enhances the waterproofing of the water-stop curtain to a certain extent, and facilitates easier sealing in case of future leaks. In summary, the waterstop plate 1 offers greater ease of use, improves waterproofing performance, reduces the difficulty of subsequent leak sealing, and further enhances construction quality.

[0039] In another embodiment of this application: the frame 11 may be integrally formed with a folded plate facing to the side, wherein one end of the folded plate is bent towards the middle of the two frames 11 to form a bent section (i.e., an L-shaped folded plate). The gap between the bent section of the folded plate and the frame 11 or the rib plate 12 is used for the insertion of the pile driver 4, and because of the formed bent section, it can just catch the edge of the pile driver 4, further limiting the position of the pile driver 4. The bottom of the pile driver 4 may be set at an angle to facilitate pressing down to break the soil.

[0040] In another embodiment of this application:

[0041] In addition to using a pile driver for installation, this application can also use a crane to install the waterstop plate 1 by hoisting. However, with conventional hoisting methods, the waterstop plate 1 sways during the lowering process. Moreover, because it is a medium-to-large-sized equipment that is hoisted from a distance, it is difficult to accurately ensure that the position does not shift when the waterstop plate 1 is fully lowered into the foundation pit.

[0042] Alternatively, the pile driver 4 can be lowered into the foundation pit first, moved in front of the waterstop plate 1, and then moved towards the waterstop plate 1 and land on the cutter head structure 16, reducing the installation difficulty of the pile driver 4. In this case, during the subsequent hammering process, it is difficult to ensure that the pile driver 4 is always stuck on the waterstop plate 1 (in the first embodiment), and the pile driver 4 may bounce out. Therefore, this application also makes the following optimization settings:

[0043] Reference Figure 4 and Figure 5 This application also includes a guiding mechanism 2 for assisting in the installation of the waterstop plate 1 and a positioning mechanism 3 for connecting the guiding mechanism 2. The guiding mechanism 2 includes a guiding plate 21, a moving trolley 22 and a connecting rod 23. The two ends of the connecting rod 23 are respectively installed on the guiding plate 21 and the moving trolley 22, and connect the guiding plate 21 and the moving trolley 22. The connection between the connecting rod 23 and the guiding plate 21 and the moving trolley 22 can be fixed by bolts and nuts, which facilitates disassembly and installation.

[0044] A gap is left between the guide plate 21 and the moving trolley 22, which allows the waterstop plate 1 and the pile driver 4 to pass through. The moving trolley 22 is slidably connected to the positioning mechanism 3. After a set of waterstop plates 1 and pile drivers 4 are installed, the moving trolley 22 can move the guide plate 21 to the next construction section in a synchronized manner.

[0045] Reference Figure 1 and Figure 6The positioning mechanism 3 includes positioning posts 35 and steel cables (not shown in the figure). There are at least two positioning posts 35, and the two positioning posts 35 are respectively installed at the two ends of one edge of the foundation pit. The upper half of the positioning post 35 is provided with a spiral blade 31. When the positioning post 35 is rotated, the spiral blade 31 is used to assist the positioning post 35 in drilling into the soil for fixation. The outer side of the upper half of the positioning post 35 is threadedly connected to a support block 32. The support block 32 can be cylindrical, and a through hole is opened in the middle for the entire positioning post 35 to pass through. Furthermore, in order to reduce the weight of the support block 32, the support block 32 can be hollow.

[0046] When the positioning column 35 is not rotated into the soil, the initial position of the support block 32 is located in the lower half of the positioning column 35 (i.e., close to the ground). After the positioning column 35 is straightened, the support block 32 is always located on the ground and close to the ground by rotating the positioning column 35 into the soil, which makes it easy to hold the positioning column 35 during construction. Considering that displacement may occur when rotating the positioning column 35, in order to facilitate fixation and construction, the bottom of the support block 32 can be integrally formed with an extension plate for workers to step on and fix, which improves the convenience of construction.

[0047] According to the above configuration, the positioning post 35 is threadedly connected to both the soil and the support block 32, further locking the positioning post 35 in place. The bottom of the positioning post 35 can be tapered, which further facilitates its penetration into the soil.

[0048] The support block 32 has a side wall hinged with an I-beam wheel 33, and the rotation surfaces of the support block 32 and the I-beam wheel 33 are perpendicular to the ground. The I-beam wheel 33 can rotate 90° and the side wall of the rotated I-beam wheel 33 is close to the ground. This arrangement makes it easier to hold the positioning column 35 and reduce the tipping caused by the excessive weight of the I-beam wheel 33 and the positioning column 35.

[0049] Reference Figure 6 When the positioning column 35 is in the initial state, the I-beam wheel 33 is rotated away from the top of the positioning column 35. At this time, the positioning column 35 is rotated to gradually drill into the soil. After the positioning column 35 is fixed, the I-beam wheel 33 is rotated to the top of the support block 32.

[0050] The positioning post 35 has a slot at its top, which can be rectangular. The top of the slot can also have a cross groove to facilitate the rotation of the positioning post 35 using tools. A square slot is formed in the center of the cross groove. After the I-beam wheel 33 rotates to the top of the support block 32, a rod 34 is inserted into the center of the I-beam wheel 33. The rod 34 can be cuboid and, when viewed from above, is a rectangle that fits into the slot. The end of the rod 34 extends out of the I-beam wheel 33 and inserts into the slot. Through the cooperation of the rod 34 and the slot, the I-beam wheel 33 can be locked to the top of the support block.

[0051] To facilitate installation and alignment, a cylinder can be inserted through the center of the I-beam wheel 33. The cylinder has a hole in the middle and openings at both ends. The hole in the middle of the cylinder can be a rectangle that fits the insertion rod 34, allowing the insertion rod 34 to be inserted. One end of the cylinder extends out of the I-beam wheel 33 for workers to hold and assist in applying force when rotating the I-beam wheel 33. The other end of the cylinder extends outward with a circular pocket plate. The upper surface of the pocket plate abuts against the lower surface of the I-beam wheel 33 to limit or fix the I-beam wheel 33.

[0052] One end of the steel cable is fixed to the I-beam 33 and the steel cable is wrapped around the middle section of the I-beam 33 for storage. The other end of the steel cable is provided with a fixing buckle for fixing the steel cable. At least one I-beam 33 is integrally formed or welded with a pull ring for connecting the fixing buckle. The fixing buckle can hook the pull ring and close the open end after the fixing buckle hooks the pull ring.

[0053] In another embodiment of this application:

[0054] Since the ground at construction sites is mostly uneven, when the mobile trolley 22 is placed and moved on the ground, its upper surface is prone to tilting due to the unevenness of the ground. This could cause the guide plate 21 and the mobile trolley 22 to tilt or break the connecting rod 23 that connects them. Therefore, the following settings are made:

[0055] Reference Figure 5 The mobile trolley 22 includes a connecting seat 221 and a base 222 arranged vertically. Multiple springs 223 and multiple telescopic rods 224 are vertically installed between the connecting seat 221 and the base 222. The ends of the springs 223 and the telescopic rods 224 are welded to the side walls of the base 222 and the connecting seat 221, respectively, close to each other. The springs 223 may be located near the edge of the mobile trolley 22, and the telescopic rods 224 may be located in the middle of the mobile trolley 22. The telescopic rods 224 can be used to limit the mobile trolley 22 to only extend and retract vertically, preventing it from swaying to the left or right. The aforementioned steel cable passes through the top of the connecting seat 221 and is fixed to another positioning post 35. Alternatively, multiple rings for the steel cable to pass through may be welded to the top of the connecting seat 221.

[0056] Through the above settings, the extension and retraction functions of spring 223 and telescopic rod 224 play a certain role in adjusting the balance of the upper surface of the moving trolley 22, so that it is as parallel as possible; among them, after the steel cable is fixed to another positioning post 35, it should be as taut as possible. When the moving trolley 22 moves under the steel cable, the taut steel cable can also play a certain pressing role on the upper surface of the moving trolley 22, so that the surface is kept as parallel as possible.

[0057] Reference Figure 4 and Figure 7A locking plate 24 connects the guide plate 21 and the adjacent waterstop plate 1. The guide plate 21 has a slot for inserting the locking plate 24. One end of the locking plate 24 is inserted into the slot of the guide plate 21, and the other end extends towards the waterstop plate 1 and then bends downward. That is, the locking plate 24 can be divided into two parallel vertical plates and a horizontal plate connecting the ends of the two vertical plates. One of the vertical plates of the locking plate 24 is inserted into the slot, and the other end is fastened to the side of the adjacent waterstop plate 1 away from the guide plate 21. In order to facilitate fastening the adjacent waterstop plate 1, the top of the waterstop plate 1 can slightly protrude from the pit (e.g., about 10 centimeters from the top of the pit).

[0058] The side wall of the slot is provided with a locking component for fixing the locking plate 24. By setting the locking component, the shaking of the locking plate 24 after it is inserted into the slot can be effectively reduced, and the probability of the locking plate 24 falling out of the slot when the waterstop plate 1 and the pile driver 4 are hit can be reduced.

[0059] According to the above configuration, the locking plate 24 fastens the guide plate 21 and the adjacent waterstop plate 1, effectively relieving the shaking caused by the vibration of the pile driver 4 after being hammered. In addition, multiple waterstop plates 1 are interlocked with each other. At this time, the locking plate 24 is fastened to the adjacent waterstop plate 1, which can borrow force from the adjacent waterstop plate 1, thereby making the guide plate 21 more stable and less prone to shaking due to hammering vibration. At the same time, the more waterstop plates 1 are connected, the greater the force borrowed, and the more stable the guide plate 21 can be.

[0060] Reference Figure 7 The locking assembly includes an abutment plate 25 and a corrugated tube 26 fixed between the abutment plate 25 and the side wall of the slot. A water-filling groove is provided in the side wall of the slot. One end of the corrugated tube 26 is bonded to the side wall of the slot and covered by the water-filling groove. The other end of the corrugated tube 26 is bonded to the abutment plate 25. The adhesive used for bonding should be a water-proof sealant.

[0061] The guide plate 21 has at least one installation groove for laying water supply pipes. The water filling tank is connected to a water pump and has at least one water inlet and one water outlet for water inlet and outlet. The water inlet and the water outlet are respectively connected to the water outlet end and the water pumping end through water pipes. With the above settings, the water filling degree in the water filling tank can be controlled by the water pumping and water delivery, that is, the degree to which the abutment plate 25 abuts against the locking plate 24, thereby locking the locking plate 24 and reducing the probability of it being dislodged from the slot due to shaking.

[0062] Reference Figure 7 The bottom of the slot is equipped with a water filling button 27 for controlling the water pump to fill. When the water filling button 27 is in the non-triggered state, it protrudes from the bottom of the slot. The water filling button 27 is electrically connected to the water pump. When the water filling button 27 is pressed down, the water pump starts to deliver water.

[0063] The abutment plate 25 is embedded with a pressure sensor, and the detection end of the pressure sensor faces the inside of the slot. The pressure sensor is used to detect the pressure of the abutment plate 25 against the locking plate 24, and to determine whether the water volume is sufficient by the pressure.

[0064] The pressure sensor is electrically connected to a controller, which is also electrically connected to the water pump. The controller is configured as follows:

[0065] If the feedback value received from the pressure sensor is greater than P, the water pump will be controlled to stop filling water. Here, P is the preset pressure value fed back by the pressure sensor when the locking plate 25 is sufficiently tightened, which is preset by the staff according to the specific situation.

[0066] With the above settings, when the locking plate 24 is inserted, the water filling button 27 is pressed down, and the water pump starts to perform water supply. The controller analyzes the pressure data feedback from the pressure sensor and determines the appropriate control to stop the water filling operation. This makes it more convenient to use. With the assistance of the pressure sensor, the locking force can be controlled more precisely, so that the pressure is sufficient to lock the locking plate 24.

[0067] In another embodiment of this application:

[0068] Reference Figure 4 The pile driver 4 has multiple distance measuring holes 41 along its length. These holes are distributed in at most half of the total length of the pile driver 4, meaning that the distance measuring holes 41 are located in one half of the pile driver 4, while no distance measuring holes 41 are provided in the other half. The spacing between the distance measuring holes 41 decreases from the middle to the ends. That is, the spacing between several distance measuring holes 41 near the middle of the pile driver 4 is larger, while the spacing between several distance measuring holes 41 near the ends of the pile driver 4 is smaller, showing a trend of gradually increasing density of the distance measuring holes 41.

[0069] A laser rangefinder sensor is embedded in the side wall of the base 222 near the pile driver 4. The detection end of the laser rangefinder sensor faces the pile driver 4. The laser rangefinder sensor is electrically connected to the controller. The controller is wirelessly connected to the display unit of the pile driving equipment used to drive the pile driver 4, such as the display built into the operator's cab of the crane mentioned above.

[0070] With the above settings, the relevant personnel of the hammer-driven pile driver 4 can observe the data of the laser rangefinder sensor and its transmission frequency transmitted back on the display. For example, if the data transmitted back by the laser rangefinder sensor are 0.8m and 0.4m respectively, and the frequency of switching to 0.4m gradually increases (that is, the time interval of transmitting 0.4m distance data gradually decreases), it indicates that the waterstop plate 1 is close to being inserted, and the hammering height or hammering force can be reduced.

[0071] By using relevant data to estimate whether the waterstop plate 1 has penetrated deeply into the soil, if the waterstop plate 1 is nearly fully inserted, the lifting height or force of the next hammer blow can be controlled to reduce, effectively preventing damage to structures such as the guide plate 21 and connecting rod 23 due to excessive hammering force, which would cause the height of the pile driver 4 to decrease as the waterstop plate 1 is inserted. Furthermore, when the pile driver 4 is pulled out, there will be a relatively long period where the data returned by the laser rangefinder is equal (small errors, such as 0.1cm, are negligible). This indicates that the pile driver 4 has been successfully pulled out, and preparations can be made for the next stage of work.

[0072] How to use:

[0073] The preparatory work (such as transporting multiple waterstop plates 1 to the construction site) is the same as in the first embodiment described above. Then, two positioning columns 35 are installed at both ends of one edge of the foundation pit. The steel cable of one of the positioning columns 35 is pulled out, passes through the ring on the top of the moving trolley 22, and is fixed to the other positioning column 35.

[0074] Secondly, the mobile trolley 22 is moved to the edge of the foundation pit where the waterstop plate 1 needs to be installed in the current work area. The waterstop plate 1 and the pile driver 4 are then placed into the foundation pit and spliced ​​through the gap between the mobile trolley 22 and the guide plate 21. It is understood that the distance between the two connecting rods 23 on the mobile trolley 22 in this application is greater than the width of the waterstop plate 1. That is, each time the mobile trolley 22 is partially located on the back of the already installed waterstop plate 1, so that when the new waterstop plate 1 passes through the above-mentioned gap, it can be spliced ​​and combined with the already installed waterstop plate 1.

[0075] Finally, the locking plate 24 is snapped into the slot and fastened to the adjacent waterstop plate 1. The pile driver 4 is hammered using relevant equipment. The data information transmitted back by the laser rangefinder is observed to analyze whether the height needs to be adjusted for the next hammering.
