Abstract
The invention discloses a waterproof board structure, which comprises a plurality of waterproof boards paved on the primary supporting surface of a tunnel or the surface of a foundation pit, wherein the plurality of waterproof boards are arranged in parallel, one end of any one waterproof board in the length direction is lapped and fixed on the upper end surface of one end of the adjacent waterproof board in the length direction at one side to form a stepped structure, and the other end of the waterproof board in the length direction is lapped and fixed on the lower end surface of one end of the adjacent waterproof board in the length direction at the other side to form a stepped structure; the long edge of the waterproof board is laid in the tunnel direction of the tunnel primary support surface or the horizontal direction of the surface of the foundation pit, and the short edge of the waterproof board is laid in the vertical direction of the tunnel primary support surface or the vertical direction of the surface of the foundation pit. Compared with the prior art, the waterproof plate structure can enable the upstream surface to be in a step shape, solves the water leakage situation at the splicing position of the waterproof plate, and can well guide water above the tunnel out.
Description
Technical Field
The invention relates to the technical field of water prevention and drainage, in particular to a waterproof board structure.
Background
Along with the economic development in recent years, the urban construction of China also develops abnormally and rapidly. From high-rise and super high-rise buildings to urban rail transit construction, related underground engineering is increasing, and a large number of deep foundation pit engineering and tunnel engineering in water-rich areas are developed. The water prevention and drainage of foundation pits, tunnels and the like become the important difficulty of water prevention and drainage nowadays, and the laying of waterproof boards is one of the important steps.
The waterproof and tunnel-waterproof part of the foundation pit is paved with a waterproof board, the surface of the waterproof board is polished and filled, and the long edge of the waterproof board is along the vertical direction of the surface of the tunnel primary support or the vertical direction of the foundation pit. The splicing parts of the waterproof boards are connected in a welding mode.
However, a large number of engineering examples show that the laying of the waterproof boards does not lead water above the tunnel out well, and the water cannot be led out well at the splicing position of the waterproof boards, so that materials are wasted, and excessive time is spent.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides a waterproof board structure.
In order to achieve the purpose, the invention is implemented according to the following technical scheme:
a waterproof board structure comprises a plurality of waterproof boards paved on the primary supporting surface of a tunnel or the surface of a foundation pit, wherein the plurality of waterproof boards are arranged in parallel, one end of any one waterproof board in the length direction is lapped and fixed on the upper end face of one end of the waterproof board adjacent to one side in the length direction to form a step-shaped structure, and the other end of the waterproof board in the length direction is lapped and fixed on the lower end face of one end of the waterproof board adjacent to the other side in the length direction to form a step-shaped structure; the long edge of the waterproof board is laid in the tunnel direction of the tunnel primary support surface or the horizontal direction of the surface of the foundation pit, and the short edge of the waterproof board is laid in the vertical direction of the tunnel primary support surface or the vertical direction of the surface of the foundation pit.
Preferably, the length of the faying surface between adjacent flashing is 80 mm.
Preferably, the adjacent waterproof boards are fixedly connected through the shooting nails.
Compared with the prior art, the waterproof plate structure can enable the upstream surface to be in a step shape, solves the water leakage situation at the splicing position of the waterproof plate, and can well guide water above the tunnel out.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. The specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The embodiment provides a waterproof board structure, and the waterproof board structure is specifically described in detail by taking the waterproof board structure laid on the surface of a foundation pit as an example. As shown in fig. 1 and 2, the waterproof board structure comprises a plurality of waterproof boards adhered on cement waterproof mortar 1 on the surface of a foundation pit, the waterproof boards are arranged in parallel, wherein one end of any one waterproof board in the length direction is lapped and fixed on the upper end surface of one end of the adjacent waterproof board in the length direction at one side to form a step-shaped structure, the other end of the waterproof board in the length direction is lapped and fixed on the lower end surface of one end of the adjacent waterproof board in the length direction at the other side to form a step-shaped structure, the length of the lapping surface is generally 80mm, in order to explain the embodiment more easily, fig. 1 only schematically shows the connection relationship between the first layer of waterproof board 2 and the second layer of waterproof board 3, the right end of the first layer of waterproof board 2 in the length direction is fixed to the lower end face of one end of the second layer of waterproof board 3 in the length direction in a lap joint manner to form a stepped structure, and the lower end faces of the first layer of waterproof board 2 and the second layer of waterproof board 3 are both adhered to the cement waterproof mortar 1 on the surface of the foundation pit; the overlapping surfaces of the first layer of waterproof board 2 and the second layer of waterproof board 3 are fixedly connected through a shooting nail 4; the long sides of the first layer of waterproof board 2 and the second layer of waterproof board 3 are laid along the horizontal direction of the surface of the foundation pit, and the short sides of the first layer of waterproof board 2 and the second layer of waterproof board 3 are laid along the vertical direction of the surface of the foundation pit.
The waterproof principle of the waterproof plate structure of the invention is as follows: the waterproof board structure can make the upstream face be cascaded, solves the condition of leaking of waterproof board concatenation department, and the water drainage with the tunnel top that moreover can be fine flows out.
The technical solution of the present invention is not limited to the limitations of the above specific embodiments, and all technical modifications made according to the technical solution of the present invention fall within the protection scope of the present invention.
