[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-3As shown, a waterproofing engineering water-stopping structure proposed in one embodiment of the utility model includes a foundation pit, wherein the foundation pit is composed of a foundation pit bottom wall 1 and a foundation pit side 2, a water-blocking block 3 is inserted into the inside of the foundation pit side 2, a plurality of rows of bite piles 4 are inserted into the inside of the foundation pit side 2, positioning columns 5 are inserted in the gaps between the bite piles 4, the positioning columns 5 are in contact with a concrete wall 6, and a reinforcing rib 7 is arranged inside the concrete wall 6; foundation pit: is the basic space for underground engineering construction, composed of a foundation pit bottom wall 1 and a foundation pit side 2.

[0025] Water blocking block 3: A single block is triangular in shape and is made of corrosion-resistant stainless steel. Multiple water blocking blocks 3 are inserted into the side edge 2 of the foundation pit to prevent or reduce groundwater from the side wall of the foundation pit from flowing into the foundation pit and enhance the water-stopping effect. Stainless steel is used to prevent corrosion from groundwater and other substances, thereby extending its service life.

[0026] Interlocking piles 4: There are at least three rows, which are interlocked and positioned. The length decreases from left to right. This design can better adapt to the shape and stress of the foundation pit and improve the stability of the structure. The main function of the interlocking piles 4 is to act as a retaining wall. Through the mutual engagement between the piles, the support capacity of the soil is enhanced to prevent soil collapse and groundwater infiltration.

[0027] Positioning column 5: inserted in the gap between the bite piles 4 and in contact with the concrete wall 6. It helps to fix and position the concrete wall 6, ensuring that the position of the wall is accurate and stable.

[0028] Concrete wall 6: It is an important part of the waterproofing project. The reinforcement ribs 7 arranged inside it are woven into a grid shape, which can improve the strength and crack resistance of the wall, enhance the overall stability of the wall, and better resist the pressure from the soil and groundwater.

[0029] This waterproofing engineering water-stopping structure forms an effective waterproofing system through the synergistic effect of various parts to ensure that the underground project is not affected by groundwater leakage during construction and use, and to ensure the safety and normal operation of the project. Specifically, the water-blocking block 3 and the bite pile 4 jointly prevent groundwater from flowing into the foundation pit, while the concrete wall 6 and its internal reinforcement 7 further enhance the waterproofing and support effect, and the positioning column 5 helps to maintain the stability of the wall.

[0030] In actual projects, the water-stop structure needs to be reasonably designed and constructed according to specific geological conditions, project requirements, construction environment and other factors to achieve the ideal waterproof effect. At the same time, the selection of anti-corrosion materials and appropriate pile types, wall structures, etc. are also the key to ensure the long-term and effective operation of the water-stop structure. In addition, relevant building specifications and standards must be followed to ensure project quality.

[0031] Principle steps: According to the design requirements and construction specifications, the foundation pit bottom wall 1 and the foundation pit side 2 are formed.

[0032] Install the water blocking blocks 3, insert the triangular anti-corrosion stainless steel water blocking blocks 3 one by one into the side 2 of the foundation pit, and install several of them continuously to form the first water blocking line to reduce the infiltration of groundwater from the side 2 of the foundation pit.

[0033] The interlocking piles 4 are driven in, and the interlocking piles 4 of decreasing length are driven in sequence from left to right according to the designed number of rows and the way of mutual engagement. Through the close engagement between the piles, a continuous retaining and water-stopping structure is formed.

[0034] Insert the positioning column 5 into the gap between the interlocking piles 4 to ensure that it is in close contact with the subsequently poured concrete wall 6, so as to play a role of positioning and supporting.

[0035] Casting concrete wall 6, a template is set on one side of the positioning column 5, and concrete is cast to form the wall.

[0036] Arrange the reinforcing ribs 7. During the process of pouring the concrete wall, arrange the reinforcing ribs 7 woven into a grid inside the concrete to enhance the strength and stability of the wall.

[0037] After the inspection and acceptance of the construction, the entire water-stop structure is inspected, including the installation and construction quality of the water-blocking blocks 3, the snap piles 4, the positioning columns 5, the concrete walls and the reinforcing ribs 7, to ensure that they meet the design requirements and waterproof standards.

[0038] It should be noted that during the actual construction process, the construction steps and processes should be appropriately adjusted and optimized according to the specific engineering conditions, geological conditions and construction technical requirements to ensure the construction quality and waterproof effect of the water-stop structure.

[0039] like Figure 2 As shown, in some embodiments, the single shape of the water blocking block 3 is a triangle, and a plurality of water blocking blocks 3 are continuously inserted into the side edge 2 of the foundation pit; the triangle is stable, can better withstand the pressure from the soil and groundwater around the foundation pit, and is not easy to deform.

[0040] like Figure 2 As shown, in some embodiments, the water blocking block 3 is made of corrosion-resistant stainless steel material and is embedded in the side 2 of the foundation pit; the use of corrosion-resistant stainless steel material is to ensure that the water blocking block 3 will not be corroded in an environment of long-term contact with groundwater and soil, thereby maintaining its good water-blocking performance and structural stability.

[0041] By inserting the water-blocking block 3, the water-blocking block 3 can be closely combined with the foundation pit side 2, reducing the gap and enhancing the water-blocking effect. This installation method can effectively fix the water-blocking block 3, so that it is not easy to shift or fall off when it is subjected to the pressure of groundwater and the surrounding soil.

[0042] like Figure 3 As shown, in some embodiments, the interlocking piles 4 have at least three rows, which are interlocked and positioned with each other, thereby enhancing the overall stability: multiple rows of piles are interlocked with each other, so that the piles can share the pressure from the surrounding soil and groundwater, thereby improving the stability of the entire support structure.

[0043] Improve water-stopping effect: Tight meshing can reduce the gap between piles and effectively prevent groundwater infiltration.

[0044] Better adaptability to complex geological conditions: In the case of complex geological conditions, multiple rows of intermeshing piles 4 can better cope with the characteristics and changes of different soil layers.

[0045] like Figure 3 As shown, in some embodiments, the bite piles 4 decrease in length from left to right; adapting to the shape and stress characteristics of the foundation pit: the shape and stress conditions of the foundation pit may not be uniform, and the bite piles 4 that decrease in length from left to right can better adapt to the stress differences at different positions, making the stress of the entire support structure more reasonable and improving stability.

[0046] Optimize material usage and cost: By reasonably adjusting the length of the pile, the material usage can be reduced and the project cost can be reduced while meeting the support and water-stopping requirements.

[0047] Facilitate construction operations: During the construction process, piles with decreasing lengths may be easier to operate the pile driver and drive in the piles, thus improving construction efficiency.

[0048] like Figure 3 As shown, in some embodiments, the reinforcing ribs 7 are woven into a grid shape; evenly distribute stress: the grid-like arrangement allows the reinforcing ribs 7 to evenly share and transfer stress in the concrete wall, thereby enhancing the tensile and shear resistance of the wall in all directions and improving the overall strength and stability of the wall.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
