Description

Technical Field

[0001] This invention relates to the field of sheet pile technology, specifically a sheet pile support sheet for building foundation pit construction. Background Technology

[0002] Sheet pile support is a common method for foundation pit construction, used to protect the stability and safety of the foundation pit. Using sheet pile support in building foundation pit construction can improve construction efficiency, reduce safety hazards during earthwork excavation, and ensure the stability and safety of the foundation pit. Sheet piles can quickly form the foundation pit retaining structure, reducing earthwork excavation time and construction cycle. The construction equipment is simple, operation is easy, and it can be put into use quickly. It can effectively prevent water and soil leakage inside and outside the foundation pit, keeping the foundation pit dry and stable. Furthermore, sheet pile materials can be reused multiple times, reducing construction costs and resource waste. Sheet pile support is suitable for various geological conditions and environments, and can adapt to different construction requirements and changes.

[0003] A Chinese patent with publication number CN211312542U discloses a steel sheet pile foundation pit support structure, including a main plate and side plates. Each side plate has a connecting hole, and a reinforcing member is installed between the two connecting holes. The reinforcing member includes a first limiting block and a second limiting block, which are respectively attached to the side of the two side plates furthest away from each other. A first rod is installed on the side of the first limiting block near the connecting hole, and a second rod is installed on the side of the second limiting block near the connecting hole. A tensioning member is installed between the first and second rods. After the first and second rods pass through the connecting holes, they are connected by the tensioning member, and the first and second limiting blocks abut against the sides of the two side plates furthest away from each other. By using the connecting holes, reinforcing member, and tensioning member, the first and second rods are passed through the connecting holes and tightened by the tensioning member, thus ensuring that the first and second limiting blocks abut against the side plates, which helps prevent the two side plates from moving away from each other during the use of the steel sheet pile.

[0004] The steel sheet pile foundation pit support structure described above is mainly designed to prevent the two sides of the steel sheet pile from moving away from each other during use. However, it does not take into account the issue of timely monitoring of foundation pit deformation. If the steel sheet pile deforms severely, it may cause instability in the foundation of the building, thereby affecting the safety of the entire building. Furthermore, if the deformation is not detected in time, it may affect the construction progress and plan, and increase construction costs and time.

[0005] Therefore, the present invention provides a steel sheet pile support steel plate for building foundation pit construction. Summary of the Invention

[0006] The purpose of this invention is to provide a steel sheet pile support steel plate for building foundation pit construction, so as to solve the technical problem mentioned in the background art that it is inconvenient to monitor the deformation of the foundation pit.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a steel sheet pile support steel plate for building foundation pit construction, comprising a steel plate body, wherein two sets of clamping plates are fixedly installed on the steel plate body, and the length of the clamping plates is equal to the length of the steel plate body;

[0008] A strip frame is fixedly installed inside the steel plate body. A reinforcing component is installed inside the strip frame. A mounting plate is installed on the strip frame. Warning lights are sequentially installed on the mounting plate. Square frames corresponding to the warning lights are sequentially installed on the mounting plate.

[0009] The square frame is equipped with a drive assembly inside, and a mounting base is fixedly installed inside the square frame. A conductive groove is embedded inside the mounting base, and the conductive groove is electrically connected to the warning light.

[0010] Preferably, the steel plate body is provided with holes in sequence, and the strip frame is provided with threaded holes corresponding to the holes. Bolts are used to connect the strip frame to the steel plate body through the holes and the threaded holes.

[0011] Preferably, angle steel is fixedly connected to both ends of the strip frame, and the angle steel is triangular in shape.

[0012] Preferably, the reinforcing component includes a frame, a first support plate, and a second support plate. The frame is sequentially arranged inside the strip frame, and the first and second support plates are staggered inside the frame. The first and second support plates are fixedly connected to the inner wall of the frame, and the first support plate passes through the interior of the second support plate.

[0013] Preferably, the frame is symmetrically provided with positioning blocks, each with a through hole. Bolts are used to connect the positioning blocks to the pre-set threaded grooves inside the strip frame through the through holes to fix the position of the frame.

[0014] Preferably, a positioning plate is connected to the frame. The positioning plate is used to connect adjacent frames. Positioning bolts are sequentially inserted on the positioning plate, and one end of the positioning bolt is connected to a pre-set threaded groove inside the strip frame to improve the stability of the frame installation.

[0015] Preferably, a battery assembly is sequentially installed inside the bar frame, and the battery assembly provides power for the warning light to operate.

[0016] Preferably, the driving component includes a square plate, an insulating plate, and a conductive block. The square plate extends through the interior of the square frame. The insulating plate is fixedly connected to one end of the square plate. The conductive block is fixedly mounted on the insulating plate, and the battery assembly is electrically connected to the conductive block. The conductive block is located directly below the conductive groove. A load-bearing block is fixedly connected to the bottom end of the square plate. A pressure plate is provided on the second support plate, and the pressure plate is located directly below the load-bearing block.

[0017] Preferably, the square frame is symmetrically provided with guide rods, and the guide rods penetrate the interior of the insulating plate. A return spring is arranged around the guide rod, and one end of the return spring is fixedly connected to the insulating plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention facilitates the monitoring of deformation points in the steel sheet pile support plates used in foundation pit construction by installing warning lights, thereby improving safety. When the soil at the edge of the foundation pit deforms, it will squeeze the steel sheet body. When the steel sheet body deforms, it will cause the reinforcing component to deform. When the reinforcing component deforms, the pressure plate will move through the second support plate. When the pressure plate moves, it will push the square plate to move through the load-bearing block. The movement of the square plate will drive the insulating plate and the conductive block to move synchronously. After the conductive block moves and contacts the conductive groove, the current inside the battery component will flow into the interior of the warning light, causing the warning light to light up. Then, the construction personnel can quickly determine the deformation point of the foundation pit by observing the working status of the warning light, which will facilitate the implementation of remedial measures to avoid accidents and improve safety.

[0020] 2. This invention improves the strength of the sheet pile support steel plates used in building foundation pit construction by installing a frame, thus supporting the foundation pit. Support plates one and two are staggered inside the frame, supporting the frame itself. Simultaneously, the frame is fixedly connected to the internal structure of the strip frame, supporting the internal structure and increasing its strength. Furthermore, the strip frame strengthens the steel plate itself, thereby improving the strength of the sheet pile support steel plates used in building foundation pit construction. This effectively prevents the steel plate from being deformed by compression, improving the stability of the foundation pit support. Attached Figure Description

[0032] Please see Figure 1 , Figure 3... Figure 4 , Figure 6 and Figure 7 An embodiment of the present invention provides a sheet pile support steel plate for building foundation pit construction, comprising a steel plate body 1, two sets of clamping plates 2 fixedly installed on the steel plate body 1, the length of the clamping plates 2 being equal to the length of the steel plate body 1, a strip frame 4 fixedly installed inside the steel plate body 1, a reinforcing component installed inside the strip frame 4, an mounting plate 16 installed on the strip frame 4, warning lights 17 sequentially installed on the mounting plate 16, and square frames 18 corresponding to the warning lights 17 sequentially installed on the mounting plate 16, a driving component installed inside the square frames 18, and a fixed component inside the square frames 18. A mounting base 23 is provided, and a conductive groove 24 is embedded inside the mounting base 23. The conductive groove 24 is electrically connected to the warning light 17. The driving assembly includes a square plate 19, an insulating plate 21, and a conductive block 22. The square plate 19 penetrates the interior of the square frame 18. The insulating plate 21 is fixedly connected to one end of the square plate 19. The conductive block 22 is fixedly mounted on the insulating plate 21, and the battery assembly 14 is electrically connected to the conductive block 22. The conductive block 22 is located directly below the conductive groove 24. A load-bearing block 20 is fixedly connected to the bottom end of the square plate 19. A pressure plate 15 is provided on the second support plate 11. The pressure plate 15 is located directly below the load-bearing block 20. When using sheet piles for foundation pit construction to support the foundation pit, the sheet pile body 1 is inserted into the ground sequentially using a pile driving device. The clamping plate 2 can connect two adjacent sets of sheet pile bodies 1. Inserting the sheet pile body 1 into the interior of the foundation pit can effectively prevent soil erosion or collapse at the edge of the foundation pit. The reinforcing component can improve the strength of the sheet pile body 1. When the soil at the edge of the foundation pit deforms, it will squeeze the sheet pile body 1. When the sheet pile body 1 deforms, it will cause the reinforcing component to deform. When the component deforms, the pressure plate 15 will move. When the pressure plate 15 moves, it will push the square plate 19 to move through the load-bearing block 20. The movement of the square plate 19 will drive the insulating plate 21 and the conductive block 22 to move synchronously. After the conductive block 22 moves and contacts the conductive groove 24, the current inside the battery assembly 14 will flow into the interior of the warning light 17, causing the warning light 17 to light up. Then, by observing the working status of the warning light 17, the construction personnel can quickly determine the deformation of the foundation pit, which will facilitate the implementation of remedial measures for the deformation of the foundation pit, avoid accidents, and improve safety.

[0033] Please see Figure 7In one embodiment of the present invention, a square frame 18 is symmetrically provided with guide rods 26, which penetrate the interior of the insulating plate 21. A return spring 27 is arranged around the guide rod 26, and one end of the return spring 27 is fixedly connected to the insulating plate 21. When the insulating plate 21 moves, the guide rod 26 guides the insulating plate 21 to a vertical sliding position. The return spring 27 applies pressure to the outer wall of the insulating plate 21, thereby limiting the position of the square plate 19 and preventing the square plate 19 from shaking.

[0034] Please see Figure 2 and Figure 3 In one embodiment of the present invention: holes 3 are sequentially provided on the steel plate body 1, and threaded holes 5 corresponding to the holes 3 are provided on the strip frame 4. Bolts are used to connect the holes 3 and the threaded holes 5 to fix the strip frame 4 on the steel plate body 1. Angle steel 6 is fixedly connected to both ends of the strip frame 4, and the angle steel 6 is triangular in shape. When the steel sheet pile support steel plate for building foundation pit construction is inserted into the foundation pit for maintenance, the angle steel 6 facilitates the entry of the strip frame 4 into the support location, and avoids the resistance exerted by the strip frame 4 when the steel sheet pile support steel plate for building foundation pit construction is inserted into the foundation pit, which would make it difficult for the steel plate body 1 to enter the soil.

[0035] Please see Figure 5 An embodiment of the present invention provides: the reinforcing component includes a frame 7, a first support plate 10, and a second support plate 11. The frame 7 is sequentially arranged inside the strip frame 4. The first support plate 10 and the second support plate 11 are staggered inside the frame 7 and are fixedly connected to the inner wall of the frame 7. The first support plate 10 penetrates the interior of the second support plate 11. The staggered arrangement of the first support plate 10 and the second support plate 11 inside the frame 7 provides support for the frame 7. At the same time, the frame 7 is fixedly connected to the interior of the strip frame 4, providing support for the interior of the strip frame 4, thereby improving the strength of the strip frame 4. Simultaneously, the strength of the steel plate body 1 is strengthened by the strip frame 4, thereby achieving the purpose of improving the steel sheet pile support steel plate used in building foundation pit construction and effectively preventing the steel plate body 1 from being deformed by compression.

[0036] Please see Figure 5 In one embodiment of the present invention, positioning blocks 8 are symmetrically arranged on the frame 7, and each positioning block 8 has a through hole 9. Bolts are used to connect the frame 7 to a pre-set threaded groove inside the strip frame 4 through the through holes 9, thereby fixing the position of the frame 7. The positioning blocks 8 are fixedly connected to the outer wall of the frame 7, and the position of the frame 7 can be fixed by the positioning blocks 8.

[0037] Please see Figure 4 and Figure 5In one embodiment of the present invention: a positioning plate 12 is connected to the frame 7, the positioning plate 12 is used to connect adjacent frames 7, positioning bolts 13 are sequentially passed through the positioning plate 12, and one end of the positioning bolt 13 is connected to a pre-set threaded groove inside the strip frame 4 to improve the stability of the frame 7 installation. A battery assembly 14 is sequentially installed inside the strip frame 4, the battery assembly 14 provides power for the warning light 17 to work, the positioning plate 12 improves the tightness of the connection between the frame 7 and the strip frame 4, and the battery assembly 14 is fixedly installed inside the strip frame 4.

[0038] Working principle: First, when using sheet piles for foundation pit construction to support the foundation pit, the sheet pile body 1 is inserted into the ground sequentially using pile driving equipment. Clamping plates 2 connect adjacent sets of sheet pile bodies 1. Inserting the sheet pile body 1 into the foundation pit effectively prevents soil erosion or collapse at the pit's edge. Reinforcing components increase the strength of the sheet pile body 1. Support plates 10 and 11 are staggered inside the frame 7, supporting the frame 7. Simultaneously, the frame 7 is fixedly connected to the strip frame 4, supporting the strip frame 4 and increasing its strength. The strip frame 4 further strengthens the sheet pile body 1, thus achieving the purpose of improving the sheet pile support for foundation pit construction and effectively preventing... The steel plate body 1 deforms under pressure. When the soil at the edge of the foundation pit deforms, it will compress the steel plate body 1. When the steel plate body 1 deforms, it will cause the reinforcing component to deform. When the reinforcing component deforms, it will cause the pressure plate 15 to move through the second support plate 11. When the pressure plate 15 moves, it will push the square plate 19 to move through the load-bearing block 20. The movement of the square plate 19 will drive the insulating plate 21 and the conductive block 22 to move synchronously. After the conductive block 22 moves and contacts the conductive groove 24, the current inside the battery component 14 will flow into the interior of the warning light 17, causing the warning light 17 to light up. Then, by observing the working status of the warning light 17, the construction personnel can quickly determine the deformation of the foundation pit, and then take remedial measures for the deformation of the foundation pit, avoid accidents, and improve safety.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
