Description

Technical Field

[0001] This invention relates to the field of foundation pit civil engineering technology, and more specifically, to a moisture-proof facility for foundation pit civil engineering construction to prevent deformation. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings. Waterproofing and drainage work should be carried out. For shallow excavations, slope protection can be used to stabilize the soil slope. The slope should be determined according to relevant construction regulations. For deeper excavations or those near buildings, excavation pit wall support methods, shotcrete wall protection methods, and even large excavation pits can use methods such as underground continuous walls and interlocking column-type bored piles to prevent the outer soil layer from collapsing. For excavations that have no impact on nearby buildings, well point method can be used to lower the groundwater level, and open excavation with slope protection can be adopted. In cold regions, natural cold air freezing method can be used for excavation, etc.

[0003] The construction of coastal foundation pit projects presents significant challenges, the most crucial being the prevention of backflow of tides. Inadequate protection can lead to seawater intrusion, necessitating pumping and reinforcement, which in turn impacts construction progress. However, existing foundation pit civil engineering tide-proofing facilities are often overly complex in design and prone to deformation under water pressure, exhibiting poor compressive strength. This makes them inconvenient to use, costly, and unusable for repeated applications.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Please see Figure 1-7According to an embodiment of the present invention, a moisture-proof facility for foundation pit construction includes a moisture-proof outer frame 1. An upper waterproof plate 2 is detachably installed on the moisture-proof outer frame 1. A water pump 3 is installed on the top of the upper waterproof plate 2, and one end of the water pump 3 is connected to an external drainage pipe 4. The moisture-proof outer frame 1, in conjunction with the other components, provides moisture protection for the foundation pit. The water pump 3 on the upper waterproof plate 2 is used to extract water seeping into the foundation pit and discharge it through the external drainage pipe 4. The moisture-proof outer frame 1 consists of four outer moisture-proof side plates 5, which are detachably connected by a snap-fit ​​structure 6. The moisture-proof outer frame 1 is composed of four outer moisture-proof side plates 5, and the snap-fit ​​structure 6 allows for easy disassembly and assembly of the moisture-proof outer frame 1, facilitating multiple uses. Each outer moisture-proof side plate 5 has an outer anti-impact structure 7 on its outer wall. The function of the stamping structure 7 is to reduce the water pressure when it is applied to the moisture-proof outer frame 1, thus preventing deformation of the moisture-proof outer frame 1. The inner sides of the outer moisture-proof side panels 5 are each equipped with an inner diagonal brace structure 8. Each inner diagonal brace structure 8 has a connecting block 9 at both ends. Adjacent connecting blocks 9 are detachably connected by a connecting rod 11 via a mounting shaft 10. The inner diagonal brace structure 8 supports the moisture-proof outer frame 1 and provides pressure relief and buffering when subjected to water pressure. This, in conjunction with the outer anti-impact structure 7, increases the stability of the moisture-proof outer frame 1. The connecting blocks 9, in conjunction with the connecting rods 11, connect the four inner diagonal brace structures 8, further enhancing overall stability. The device of this application has a simple structure, is easy to assemble and disassemble, can be reused multiple times, and has high overall structural strength and stability. It can reduce the pressure exerted by water on the moisture-proof outer frame 1, thereby preventing deformation.

[0030] In one embodiment, please refer to the appendix to the specification.

Elastic sealing gaskets 18 are symmetrically arranged within the snap-fit ​​grooves 17. Connecting side plates 19 are symmetrically arranged on the strip snap-fit ​​plate 16, with three sets of mounting holes 20. A rotating threaded rod 21 is threaded through the strip snap-fit ​​plate 16. A rotating handle 23 is symmetrically arranged at the top of the rotating threaded rod 21, and a threaded positioning pin 22 is provided at the bottom of the rotating threaded rod 21. The two snap-fit ​​grooves 17 facilitate the installation of the outer moisture-proof side plate 5. The elastic sealing gaskets 18 prevent water seepage. The connecting side plates 19, in conjunction with the mounting holes 20, are bolted to the outer moisture-proof side plate 5. When fixing the strip snap-fit ​​plate 16, the rotating threaded rod 21 can be rotated to rotate the threaded positioning pin 22 into the ground, thus enabling installation.

[0032] In one embodiment, please refer to the appendix to the specification. Figure 1 and Figure 5 As shown, the outer anti-impact structure 7 includes snap-fit ​​plates 24 that match the snap-fit ​​grooves 17 and are installed at both ends of the outer moisture-proof side plate 5. Reinforcing side plates 25 are symmetrically arranged on the outer side of the outer moisture-proof side plate 5.

A corrugated plate 27 is provided on the lower arc-shaped support plate 26, and a support plate 28 is connected to the top of the reinforcing side plate 25. The reinforcing side plates 25, in conjunction with the lower arc-shaped support plate 26, block water flow, and the corrugated plate 27 reduces the pressure of the water flow on the outer moisture-proof side plate 5, preventing deformation.

[0033] In one embodiment, please refer to the appendix to the specification. Figure 6 and 7As shown, the inner diagonal bracing structure 8 includes a supporting horizontal plate 29 connected to the inner wall of the outer moisture-proof side plate 5. Mounting plates 30 are symmetrically arranged on both sides of the supporting horizontal plate 29. An inner supporting diagonal rod 32 is connected to the bottom of the supporting horizontal plate 29 via a pressure-resistant reset structure 31. A lower horizontal plate 33 is installed at the bottom of the inner supporting diagonal rod 32. A lower insertion plate 34 is provided at the bottom of the lower horizontal plate 33. Side blocking plates 35 are symmetrically arranged on the lower insertion plate 34. The pressure-resistant reset structure 31 includes components located on the supporting horizontal plate 29. 9. The bottom has a mounting groove 36, in which a guide cylinder 37 is fixedly installed. A guide sleeve 38 is movably fitted on the guide cylinder 37. The bottom of the guide sleeve 38 is connected to the inner support inclined rod 32. Both ends of the guide sleeve 38 are connected to a movable support plate 40 through a connecting rod 39. The movable support plate 40 is movably fitted on the guide cylinder 37. A compression spring 41 fitted on the guide cylinder 37 is connected to the side of the movable support plate 40 away from the guide sleeve 38. The supporting horizontal plate 29 is used to connect to the inner wall of the outer moisture-proof side plate 5. The inner supporting diagonal rod 32 works with the lower horizontal plate 33 to fix the bottom end. The lower insertion plate 34 works with the side blocking plate 35 to increase the resistance to the ground after being inserted into the ground, preventing displacement. The pressure-resistant reset structure 31 is used to transfer the pressure of the water flow to the supporting horizontal plate 29 when it is applied to the outer moisture-proof side plate 5, causing the supporting horizontal plate 29 to move backward. The guide sleeve 38 set on the guide cylinder 37 works with the movable support plate 40 and the compression spring 41 to ensure the position of the guide sleeve 38, thereby achieving the connection stability of the inner supporting diagonal rod 32.

[0034] In practical applications, the moisture-proof outer frame 1, in conjunction with the existing moisture-proof outer frame 2, can prevent moisture from seeping into the foundation pit. A water pump 3 mounted on the upper waterproofing plate 2 is used to extract water seeping into the foundation pit and discharge it through the external drainage pipe 4. The moisture-proof outer frame 1 is composed of four external moisture-proof side panels 5, which are connected by a snap-fit ​​structure 6, allowing for easy disassembly and reassembly of the moisture-proof outer frame 1 for repeated use. The external anti-impact structure 7 reduces water pressure when it hits the moisture-proof outer frame 1, preventing deformation. The inner diagonal bracing structure 8 supports the moisture-proof outer frame 1. When it is subjected to water pressure, it can relieve pressure and buffer. It works in conjunction with the outer anti-impact structure 7 to increase the stability of the moisture-proof outer frame 1. The connecting block 9, in conjunction with the connecting rod 11, connects the four inner diagonal bracing structures 8 to increase the overall stability. The device of this application has a simple structure, is very convenient to assemble and disassemble, can be used multiple times, and has high overall structural strength and good stability. It can reduce the pressure of water flow on the moisture-proof outer frame 1, thereby preventing deformation.

[0035] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
