Problems solved by technology

[0003] Existing designs mostly focus on the overall pouring of the underground structure and pier columns. The overall design is prone to cracking of the underground structure under the action of dynamic loads, vibrations and other factors generated by train operation. Under long-term action, water leakage or even Structural Safety Issues
For the separate design of underground structures and pier columns, if the protruding ground treatment cannot be done, the general consideration is to carry out waterproof treatment underground; the durability of waterproof materials is limited, and water leakage will easily occur after a long time. High operation and maintenance costs affect the experience of using underground space

Embodiment 1

[0029] Such as figure 1 As shown, Embodiment 1 of the present invention provides an underground structure and piers separated node waterproof system, which includes an underground structure 1 and piers 2, the underground structure 1 is provided with a through hole, and the pier 2 is pierced through the through hole. A gap 3 is provided between the outer wall of the pier column 2 and the inner wall of the through hole; the gap 3 is filled with a flexible caulking material 4, the bottom of the gap 3 is provided with a drainage device 7, and the bottom of the drainage groove 701 communicates with the drain pipe 702; An outwardly protruding ear plate 201 is provided on the outer wall of the pier 2 , and a flexible sealing material 5 is provided between the bottom of the ear plate 201 and the top of the flexible caulking material 4 .

[0030] In the area where the pier column 2 passes through the underground structure 1, a through hole is opened in the structure, and gaps are reser...

Embodiment 2

[0044] Such as image 3 As shown, Embodiment 2 of the present invention provides another embodiment of the drainage and drainage device 7 of the underground structure and pier-column separated node waterproof system. The inner walls on both sides of the drainage groove 701 are respectively in the same On the horizontal line, both sides of the drainage groove 701 are provided with stainless steel plates 704, and the stainless steel plates 704 start to bend downward at the inner wall of the gap 3 and extend into the drainage groove 701; After being folded and extending along the horizontal direction, it is fixed to the pier column 2 by bolts 14, and a rubber gasket 10 is provided between the top edge of the drainage groove 701 and the pier column 2, and the stainless steel plate 704 is fixed on the pier column 2 by shooting nails 13. Bolts 14 pass through the top edge of the drainage groove 701, the rubber gasket 10 and the stainless steel plate 704 to fix the bottom of the pier...

Abstract

The invention belongs to the technical field of underground structure water prevention and particularly relates to an underground structure and pier stud separating type node water prevention system which comprises an underground structure and a pier stud. The underground structure is provided with a through hole. The pier stud is arranged in the through hole in a penetrating manner. A gap is arranged between the outer wall of the pier stud and the inner wall of the through hole. The gap is filled with a flexible gap filling material. The bottom of the gap is provided with a water draining device. A lug plate protruding outwards is arranged on the outer wall of the pier stud. A flexible sealing material is arranged between the bottom of the lug plate and the top of the flexible seam filling material. According to the underground structure and pier stud separating type node water prevention system, the gap between the underground structure and the pier stud drains possible leaked waterin an organized manner, the water draining device is arranged on the bottom of the gap, the situation that water is leaked from a separating node between the pier stud and the underground structure irregularly, and use experience of underground space is influenced.

Description

technical field [0001] The invention belongs to the technical field of waterproofing of underground structures, and in particular relates to a joint waterproofing system for underground structures and pier columns, which is suitable for comprehensive transportation hub projects of station buildings, house construction projects, bridges and underground structure projects, and the like. Background technique [0002] The comprehensive transportation hub project with the integrated design of the national railway station building and the subway is becoming more and more common. In this mode, the station building columns, main line bridge piers and ramp bridge piers may all fall within the scope of the subway station structure, which is different from the subway structure. joint construction. The main line bridge structure must meet the requirements of trains passing through stations at normal speeds per hour, and the load is relatively large and dynamic. In order to avoid adverse...
