Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for civil engineering construction, specifically to a civil engineering construction auxiliary equipment with a supporting function. Background Technology

[0002] Civil engineering is a general term for the science and technology of constructing various land engineering facilities. It refers not only to the materials and equipment used and the technical activities such as surveying, design, construction, maintenance, and repair, but also to the objects of engineering construction, namely, various engineering facilities built on or under the ground, on land, that directly or indirectly serve human life, production, military, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, and protective engineering, etc. Civil engineering refers to the various technical work and the completed engineering entities of buildings, structures, and related supporting facilities for the construction, reconstruction, or expansion of various projects, excluding building construction, including surveying, planning, design, construction, installation, and maintenance.

[0003] Trenching is a fundamental and frequently used process in civil engineering construction. It is mainly used to excavate various underground trenches, walls, or ground channels to meet the needs of pipeline laying, foundation construction, and structural reservation. The purpose, specifications, and construction methods of trenching vary greatly depending on the construction scenario.

[0004] When trenches are dug, construction workers need to enter the trench to work. The soil on both sides of the trench is unstable and prone to collapse. Support equipment is needed to support the soil on both sides during construction. However, due to the simple structure of the current support equipment, it is not able to handle emergency situations when it rains. Rainwater accumulation and erosion inside the trench can cause cavities to appear at the bottom of the support equipment. Without support at the bottom, the support will go from being evenly supported to being suspended on one side. The support will tilt towards the side with the cavity. If the water continues to erode and the cavity expands, the support will collapse directly. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a civil engineering construction auxiliary device with a supporting function, solving the problems of current support equipment having a simple structure, being unable to handle emergency situations in rainy weather, and the accumulation of water and erosion inside the trench during rainy weather causing voids at the bottom of the support equipment, which will tilt towards the voids due to the lack of support at the bottom.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a civil engineering construction auxiliary equipment with a supporting function, comprising two side support frames for supporting the soil of the inner wall of the trench, and a plurality of supporting rods are provided between the two side support frames;

[0007] The side support frame has a filling cavity inside. Multiple support connecting blocks are installed on the inner wall of the filling cavity of the side support frame. At least one inner reinforcing support plate is fixedly installed on the side of the multiple support connecting blocks. The side of the side support frame is provided with a filling hopper. A sealing and waterproofing plate is detachably installed on the filling hopper. Two limiting guide plates are fixedly installed inside the side support frame. The sealing and waterproofing plate is slidably disposed between the two limiting guide plates. The inner wall of the filling hopper is provided with a feeding inclined guide plate to avoid filling accumulation. The side support frame is provided with an automatic opening and closing mechanism to drive the sealing and waterproofing plate to move.

[0008] The bottom of the side support frame is equipped with an automatic filling mechanism, which is used to automatically fill the soil lost at the bottom of the trench.

[0009] By adopting the above technical solution, and by setting up side support frames, support rods, internal reinforcing support plates, filling hoppers, sealing and waterproofing plates, limiting guide plates, feeding inclined guide plates and automatic opening and closing mechanisms, the side support frames and support rods can support the soil on the inner wall of the trench, thereby achieving soil support and preventing accidents such as soil collapse during construction work, thus ensuring the safety of construction workers.

[0010] The internal reinforced support plate provides further support and protection. Utilizing the filler hopper and sealing waterproof plate, the filler hopper is connected to the internal cavity of the side support frame. By filling the cavity of the side support frame with different fillers, graded strength support can be achieved, which can adapt to the strength requirements of different soil layers and different trench depths in trench support. It can also solve the problems of fixed strength of traditional rigid support plates and easy mismatch with soil stress.

[0011] The compressive strength and deformation modulus of the cavity filler are used to adjust the overall support strength of the support plate. The inner reinforced support plate also plays a role in sharing the soil pressure. The automatic opening and closing mechanism can control the automatic opening and closing of the sealing and waterproofing plate, which facilitates the filling work of construction personnel.

[0012] Preferably, the automatic opening and closing mechanism includes an L-shaped movable plate and a protective bracket. The movable plate is slidably disposed within the cavity of the side support frame, and the lateral portion of the movable plate is slidably mounted on the outer surface of the inner reinforcing support plate. An adsorption magnetic block one is fixedly installed on the inner wall of the protective bracket, and an opening is provided on the movable plate to cooperate with the adsorption magnetic block one. An adsorption magnetic block two to cooperate with the adsorption magnetic block one is fixedly installed on the side of the sealing waterproof plate.

[0013] Preferably, a wedge block one is fixedly installed on the top of the movable plate, and a plurality of guide sliding blocks are fixedly installed on the top of the sealing and waterproofing plate. The plurality of guide sliding blocks are slidably disposed in the sliding groove opened on the upper limiting guide plate, and a wedge block two that cooperates with the wedge block one is fixedly installed on the top of the guide sliding block.

[0014] Preferably, a plurality of reset elastic elements are installed on the top of the wedge block, and the top ends of the plurality of reset elastic elements are all fixedly installed on the inner wall of the protective bracket.

[0015] Preferably, the automatic filling mechanism includes a bottom extension bracket and a connecting block slidably disposed on the side support frame and the bottom extension bracket. The top of the connecting block is in contact with the bottom of the inner reinforcing support plate. Several partition plates are fixedly installed inside the bottom extension bracket. The connecting block is divided into multiple plates corresponding to several contact plates. Multiple filling ports are opened at the bottom of the side support frame and the top of the bottom extension bracket. The multiple plates are slidably disposed inside the filling ports. A driving component for driving the connecting block up and down is provided inside the bottom extension bracket.

[0016] Preferably, the drive assembly includes a limiting guide rod slidably disposed on the partition plate frame, a sliding support plate is fixedly installed on the top of the limiting guide rod, a connecting block is fixedly installed on the top of the sliding support plate, and the top of the connecting block slides through the side support frame and fits against the bottom of the inner reinforcing support plate.

[0017] Preferably, the bottom of the limiting guide rod is fixedly installed with a contact plate for contacting the soil at the bottom of the trench, and the bottom extension bracket has a groove for the contact plate to be inserted into.

[0018] Preferably, a plurality of reset elastic elements II are fixedly installed on the top of the partition plate frame, and the top ends of the plurality of reset elastic elements II are all fixedly installed on the lower surface of the sliding support plate.

[0019] Preferably, the support rod includes a plurality of inner support rods threadedly detachably mounted on one of the side supports, and a plurality of support adjusting cylinders threadedly detachably mounted on the other side support, wherein the inner support rods are slidably mounted inside the support adjusting cylinders.

[0020] Preferably, a plurality of drainage guide pipes are installed on the bottom extension bracket, and the drainage guide pipes are located above the soil at the bottom of the trench.

[0021] Working principle:

[0022] In use, by installing and replacing support inner rods and support adjustment cylinders of different specifications and lengths, the support inner rods are inserted into the support adjustment cylinders to support the two side support frames. At the same time, the spacing between the two side support frames can be adjusted to support trenches of different widths.

[0023] During placement, the two side support frames are lifted by hoisting equipment, moved to the trench position, and placed inside the trench so that the two side support frames come into contact with the soil on both sides of the trench to support the trench.

[0024] After placement, filler material can be added into the side support frame through the filler hopper. By filling the cavity of the side support frame with different filler materials, graded strength support can be achieved to meet the strength requirements of different soil layers and different trench depths in trench support.

[0025] When filling the cavity of the side support frame, the L-shaped moving plate will move downward under the influence of the weight of the filling. When the moving plate moves to the bottom, it will drive the two wedge blocks to move horizontally in sync. The movement of the first wedge block will drive the sealing and waterproofing plate to move, automatically sealing the filling hopper.

[0026] When construction cannot avoid rainy days, some sand and cement soil can be filled at the bottom of the side support frame. When water accumulates, the drainage pipe can be used to drain the water from the bottom of the trench.

[0027] Due to the influence of rainwater erosion on the soil at the bottom of the trench, if the soil at the bottom of the trench is lost and cavities appear, the bottom of the limiting guide rod will slide downwards due to lack of support. At the same time, during the downward movement of the limiting guide rod, it will drive the connecting block to move downwards in sync through the sliding support plate, so that the connecting block will disengage from the filling port. At this time, the filling material inside the side support frame will automatically flow out from the filling port to complete the filling work.

[0028] This invention provides a civil engineering construction auxiliary device with supporting function. It has the following beneficial effects:

[0029] 1. This invention, by setting up a side support frame, support rods, an inner reinforcing support plate, a filler hopper, a sealing and waterproofing plate, a limiting guide plate, a discharge inclined guide plate, and an automatic opening and closing mechanism, utilizes the side support frame and support rods to support the soil on the inner wall of the trench, achieving soil support and preventing accidents such as soil wall collapse during construction work, thus ensuring the safety of construction personnel. The inner reinforcing support plate provides further support and protection. The filler hopper and sealing and waterproofing plate, along with the side support frame and support rods, provide further support and protection. The internal cavities of the support frame are interconnected. By filling the cavities of the side support frame with different fillers, graded strength support can be achieved, adapting to the strength requirements of different soil layers and trench depths in trench support. It can also solve the problems of fixed strength of traditional rigid support plates and mismatch with soil stress. The compressive strength and deformation modulus of the cavity filler are used to adjust the overall support strength of the support plate. The internal reinforcing support plate also plays a role in sharing soil pressure. The automatic opening and closing mechanism can control the automatic opening and closing of the sealing waterproof plate, which is convenient for construction personnel to carry out filling work.

[0030] 2. This invention, by setting up an adsorption magnetic block one, an adsorption magnetic block two, and a movable plate, ensures that when the inside of the side support frame is completely open, the movable plate will be located at the top of the cavity inside the side support frame. At this time, the opening on the movable plate will be exactly at the position of the adsorption magnetic block one. Under the action of the adsorption magnetic block one, the adsorption magnetic block two will be adsorbed, causing the adsorption magnetic block two to move the sealing waterproof plate closer to the adsorption magnetic block one. The sealing waterproof plate will move away from the position of the filler hopper, thus releasing the sealing work on the filler hopper and facilitating the workers to carry out the filler work.

[0031] 3. By setting up wedge block one, wedge block two and guide sliding block, when filling the cavity of the side support frame, the L-shaped moving plate will move downward under the influence of the weight of the filling. When the moving plate moves to the bottom, it will drive wedge block two to move horizontally in sync with the downward movement of wedge block one. The movement of wedge block one drives the sealing and waterproofing plate to move, thus automatically realizing the sealing of the filling hopper.

[0032] 4. This invention, by setting a limiting guide rod, a sliding support plate, a connecting block, and a driving component, utilizes the driving component to move the connecting block up and down, thereby adjusting the height of the connecting block. When construction cannot avoid rainy days, some sand and cement soil can be filled at the bottom of the side support frame. Due to the erosion of the soil at the bottom of the trench by rainwater, there will be some loss. The bottom of the limiting guide rod will slide downwards due to lack of support. At the same time, during the downward movement of the limiting guide rod, the sliding support plate will drive the connecting block downwards synchronously, causing the connecting block to detach from the filling port. At this time, the filling material inside the side support frame will automatically flow out from the filling port and fill the void at the bottom of the side support frame. The void is backfilled with sand and cement soil to prevent the bottom of the support from being suspended. At the same time, the sand and gravel can block the water flow from eroding the bottom of the trench, avoiding problems such as support tilting and collapse.

[0033] 5. This invention, by setting up an inner support rod and a support adjustment cylinder, and by installing and replacing inner support rods and support adjustment cylinders of different specifications and lengths, inserts the inner support rod into the support adjustment cylinder to achieve support for the two side support frames. At the same time, it can also adjust the spacing between the two side support frames, enabling support for trenches of different widths and improving the scope of application.

[0045] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0046] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a civil engineering construction auxiliary device with a supporting function, including two side support frames 1 for supporting the soil inside the trench, and a plurality of supporting rods 2 between the two side support frames 1.

[0047] The side support frame 1 has a filling cavity inside. Multiple support connecting blocks 10 are installed on the inner wall of the filling cavity of the side support frame 1. At least one inner reinforcing support plate 8 is fixedly installed on the side of the multiple support connecting blocks 10. The side of the side support frame 1 is provided with a filling hopper 4. A sealing waterproof plate 5 is detachably installed on the filling hopper 4. Two limiting guide plates 707 are fixedly installed inside the side support frame 1. The sealing waterproof plate 5 is slidably disposed between the two limiting guide plates 707. The inner wall of the filling hopper 4 is provided with a feeding inclined guide plate 6 to avoid filling accumulation. The side support frame 1 is provided with an automatic opening and closing mechanism 7 to drive the sealing waterproof plate 5 to move.

[0048] The bottom of the side support frame 1 is equipped with an automatic filling mechanism 9, which is used to automatically fill the soil lost at the bottom of the trench.

[0049] By setting up a side support frame 1, support rods 2, inner reinforcing support plate 8, filler hopper 4, sealing and waterproofing plate 5, limiting guide plate 707, discharge inclined guide plate 6, and automatic opening and closing mechanism 7, the side support frame 1 and support rods 2 can support the soil on the inner wall of the trench, thus protecting the soil and preventing accidents such as soil collapse during construction work, ensuring the safety of construction workers. The inner reinforcing support plate 8 provides further support and protection. The filler hopper 4 and sealing and waterproofing plate 5... It is connected to the internal cavity of the side support frame 1. By filling the cavity of the side support frame 1 with different fillers, graded strength support can be achieved, which can be adapted to the strength requirements of different soil layers and different trench depths in trench support. It can also solve the problem of fixed strength of traditional rigid support plates and easy mismatch with soil stress. The compressive strength and deformation modulus of the cavity filler can be used to adjust the overall support strength of the support plate. The inner reinforcing support plate 8 also plays the role of sharing soil pressure. The automatic opening and closing mechanism 7 can control the automatic opening and closing of the sealing waterproof plate 5, which is convenient for construction personnel to carry out filling work.

[0050] For details, please refer to the appendix. Figure 3 Appendix Figure 6 -Appendix Figure 8 The automatic opening and closing mechanism 7 includes an L-shaped movable plate 703 and a protective bracket 701. The movable plate 703 is slidably disposed in the cavity of the side support frame 1, and the lateral part of the movable plate 703 is slidably installed on the outer surface of the inner reinforcing support plate 8. An adsorption magnetic block 708 is fixedly installed on the inner wall of the protective bracket 701, and an opening is provided on the movable plate 703 to cooperate with the adsorption magnetic block 708. An adsorption magnetic block 709 to cooperate with the adsorption magnetic block 708 is fixedly installed on the side of the sealing waterproof plate 5.

[0051] By setting up magnetic adsorption block 1 708, magnetic adsorption block 2 709, and moving plate 703, when the inside of the side support frame 1 is completely open, the moving plate 703 will be located at the top of the cavity inside the side support frame 1. At this time, the opening on the moving plate 703 will be exactly at the position of magnetic adsorption block 1 708. Under the action of magnetic adsorption block 1 708, magnetic adsorption block 2 709 will be adsorbed, causing magnetic adsorption block 2 709 to move the sealing waterproof plate 5 closer to magnetic adsorption block 1 708. The sealing waterproof plate 5 will move away from the position of the filling hopper 4, releasing the sealing work on the filling hopper 4, making it easier for the staff to carry out the filling work.

[0052] For details, please refer to the appendix. Figure 7 and attached Figure 8The top of the movable plate 703 is fixedly installed with a wedge block 704, and the top of the sealing waterproof plate 5 is fixedly installed with multiple guide sliding blocks 706. The multiple guide sliding blocks 706 are slidably arranged in the sliding groove opened on the upper limiting guide plate 707, and the top of the guide sliding block 706 is fixedly installed with a wedge block 705 that cooperates with the wedge block 704.

[0053] By setting wedge block 1 704, wedge block 2 705 and guide sliding block 706, when filling the cavity of the side support frame 1, the L-shaped moving plate 703 will move downward under the influence of the weight of the filling. When the moving plate 703 moves to the bottom, it will drive wedge block 2 705 to move downward in sync, causing wedge block 1 704 to move laterally. The movement of wedge block 1 704 drives the sealing and waterproofing plate 5 to move, automatically realizing the sealing work of the filling hopper 4.

[0054] For details, please refer to the appendix. Figure 7 Several reset elastic elements 702 are installed on the top of the wedge block 704, and the top ends of the several reset elastic elements 702 are fixedly installed on the inner wall of the protective bracket 701.

[0055] By setting a reset elastic element 702, the reset elastic element 702 supports and resets the wedge block 705 and the moving plate 703. When there is no filling inside the side support frame 1, the moving plate 703 can always be kept in the uppermost position, thereby ensuring that the sealing waterproof plate 5 and the filling hopper 4 can remain open. During the filling process, it supports the moving plate 703 and prevents the moving plate 703 from moving directly to the bottom, which would cause insufficient filling. The reset elastic element 702 can be an adjustable elastic element, such as an adjustable helical spring assembly.

[0056] For details, please refer to the appendix. Figure 3 -Appendix Figure 5The automatic filling mechanism 9 includes a bottom extension bracket 907 and a connecting block 901 slidably disposed on the side support frame 1 and the bottom extension bracket 907. The top of the connecting block 901 is in contact with the bottom of the inner reinforcing support plate 8. Several partition plates 906 are fixedly installed inside the bottom extension bracket 907. The connecting block 901 is divided into multiple plates corresponding to several contact plates 905. Multiple filling ports are opened at the bottom of the side support frame 1 and the top of the bottom extension bracket 907. Multiple plates are slidably disposed inside the filling ports. The bottom extension bracket 907 is provided with a driving assembly for driving the connecting block 901 up and down. The driving assembly includes a limiting guide rod 904 slidably disposed on the partition plate 906. A sliding support plate 902 is fixedly installed on the top of the limiting guide rod 904. The connecting block 901 is fixedly installed on the top of the sliding support plate 902. The top of the connecting block 901 slides through the side support frame 1 and is in contact with the bottom of the inner reinforcing support plate 8.

[0057] By setting up a limiting guide rod 904, a sliding support plate 902, a connecting block 901, and a driving component, the driving component can drive the connecting block 901 to move up and down, thereby adjusting the height of the connecting block 901. When construction cannot avoid rainy days, some sand and cement soil can be filled at the bottom of the side support frame 1. Due to the impact of rainwater erosion, the soil at the bottom of the trench may be washed away. The limiting guide rod 904 will slide downwards due to lack of support at the bottom. At the same time, during the downward movement of the limiting guide rod 904, it will drive the connecting block 901 downwards synchronously through the sliding support plate 902, causing the connecting block 901 to detach from the filling port. At this time, the filling material inside the side support frame 1 will automatically flow out from the filling port and fill the void at the bottom of the side support frame 1. The void is backfilled with sand and cement soil to prevent the bottom of the support from being suspended. At the same time, the sand and gravel can block the water flow from eroding the bottom of the trench, avoiding problems such as support tilting and collapse.

[0058] For details, please refer to the appendix. Figure 4 Appendix Figure 5 Appendix Figure 9 and attached Figure 10 The bottom of the limiting guide rod 904 is fixedly installed with a contact plate 905 for contacting the soil at the bottom of the trench, and the bottom of the bottom extension bracket 907 is provided with a groove for the contact plate 905 to be inserted. The top of the partition plate frame 906 is fixedly installed with several reset elastic elements 903, and the tops of the several reset elastic elements 903 are all fixedly installed on the lower surface of the sliding support plate 902.

[0059] By setting up a contact plate 905 and a reset elastic element 903, the contact plate 905 can expand the contact area with the soil at the bottom of the trench, avoiding the problem that the limiting guide rod 904 will sink into the depth when some soil is soft during normal use. Specifically, the reset elastic element 903 is used to apply downward force to the sliding support plate 902 and the limiting guide rod 904. The downward movement of the limiting guide rod 904 can drive the contact plate 905 to move downward synchronously, so that it can move downward quickly when the bottom soil is lost, thus realizing the filling work.

[0060] Please see the appendix Figure 1 The support rod 2 includes several inner support rods 201 that are threadedly detachably installed on one of the side support frames 1, and several support adjusting cylinders 202 that are threadedly detachably installed on the other side support frame 1. The inner support rods 201 are slidably installed inside the support adjusting cylinders 202.

[0061] By setting up the inner support rod 201 and the support adjustment cylinder 202, and by installing and replacing the inner support rod 201 and the support adjustment cylinder 202 with different specifications and lengths, the inner support rod 201 is inserted into the support adjustment cylinder 202 to support the two side support frames 1. At the same time, the distance between the two side support frames 1 can be adjusted to support the trenches of different widths, thereby improving the applicability.

[0062] For details, please refer to the appendix. Figure 1 Several drainage pipes 3 are installed on the bottom extension bracket 907, and the drainage pipes 3 are located above the soil at the bottom of the trench.

[0063] By setting up drainage pipe 3, the accumulated water at the bottom of the ditch can be discharged. At the same time, a cavity is reserved between drainage pipe 3 and the soil at the bottom of the ditch, so that a small amount of water can be retained at the bottom of the ditch. This prevents the dynamic water pressure from further eroding the bottom during the pumping process, thus preventing the cavity from continuing to expand.

[0064] Working principle:

[0065] In use, by installing and replacing the inner support rods 201 and the support adjusting cylinders 202 of different specifications and lengths, the inner support rods 201 are inserted into the support adjusting cylinders 202 to support the two side support frames 1. At the same time, the distance between the two side support frames 1 can be adjusted to support and protect trenches of different widths.

[0066] During placement, the two side support frames 1 are lifted by hoisting equipment, moved to the trench position, and placed inside the trench so that the two side support frames 1 come into contact with the soil on both sides of the trench to support the trench.

[0067] After placement, filler material can be added into the side support frame 1 through the filler hopper 4. By filling the cavity of the side support frame 1 with different filler materials, graded strength support can be achieved to meet the strength requirements of different soil layers and different trench depths in trench support.

[0068] When filling the cavity of the side support frame 1, the L-shaped moving plate 703 will move downward under the influence of the weight of the filling. When the moving plate 703 moves to the bottom, it will drive the second wedge block 705 to move downward in sync, and drive the first wedge block 704 to move laterally. The movement of the first wedge block 704 will drive the sealing and waterproofing plate 5 to move, and automatically realize the sealing work of the filling hopper 4.

[0069] When construction cannot avoid rainy days, some sand and cement soil can be filled at the bottom of the side support frame 1. When water accumulates, the drainage pipe 3 can be used to drain the water at the bottom of the trench.

[0070] Due to the influence of rainwater erosion on the soil at the bottom of the trench, if the soil at the bottom of the trench is lost and cavities appear, the bottom of the limiting guide rod 904 will slide downwards due to lack of support. At the same time, during the downward movement of the limiting guide rod 904, it will drive the connecting block 901 downwards through the sliding support plate 902, so that the connecting block 901 will disengage from the filling port. At this time, the filling material inside the side support frame 1 will automatically flow out from the filling port to complete the filling work.

[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
