Description

Subway secretly digs station and prevents drainage structure

Technical Field

The utility model relates to a tunnel drainage engineering field specifically is a subway secretly digs station and prevents drainage structure.

Background

In recent years, some cities develop rapidly, the population increases explosively, the ground traffic pressure of the cities is increased rapidly, and most cities begin to build subway rail traffic to relieve the ground traffic pressure, but the problems of traffic jam are caused by greenbelt migration, underground pipelines are rearranged, a basement stratum is deeper and the construction, so that the subway construction needs to basically place the main structure of a subway station in a hard rock stratum and adopt a subsurface excavation method for construction.

The construction of the underground excavation method needs to consider the water seepage problem of a tunnel structure, but underground water in a rock stratum is generally bedrock fracture water, although the water quantity is not large, the water head is higher, the existing method mostly adopts a full-package waterproof mode, namely a secondary lining and an inverted arch structure, and the seepage is easily caused at construction joints and deformation joints when the underground excavation method bears high water pressure for a long time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a subway secretly digs station and prevents drainage structure to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a subway secretly digs station drainage structures, is including installing in the concrete layer of rock base layer, be provided with the infiltration hole on the concrete layer, install the breakwater on the concrete layer, its characterized in that, the infiltration hole on the concrete layer is deepened the inside of rock base layer, infiltration hole evenly distributed is at the well downside of concrete layer, evenly install connecting bolt on the concrete layer, the breakwater passes through connecting bolt and links to each other with the breakwater, breakwater and base sealing connection, the pedestal mounting is on main tributary dagger and vice support column.

Concrete layer laminating rock-based layer, with the firm contact of rock-based layer, and play effective support and fixed action, the infiltration hole is arranged in leading a small amount of infiltration in the rock-based layer, because the rock structure of rock-based layer makes the infiltration volume less, and the infiltration is easy to be collected toward crack and breach department under the extrusion of rock, the infiltration hole only need in the ground layer the downside evenly lay can, can effectively water conservancy diversion whole concrete layer's infiltration.

Further, connecting bolt is stud, stud one end links to each other with concrete layer, the stud other end is equipped with connecting thread, stud one end links to each other with the breakwater, connecting bolt's middle part is provided with the flange.

Specifically, one end of the stud bolt is of a screw structure, the stud bolt is installed in a mode of knocking and nailing into a concrete layer, and the other end of the stud bolt is provided with connecting threads, so that the stud bolt is convenient to install a water baffle in combination with a nut.

Furthermore, the flange is connected with the water baffle through a nut, a first gasket is arranged between the flange and the water baffle, and a second gasket is arranged between the nut and the water baffle.

Specifically, first gasket and second gasket are used for plugging up the bolt hole of cooperation connecting bolt on the baffle, further avoid the possibility of infiltration.

Furthermore, a drain pipe is arranged below the base and connected with a city pipe network.

Specifically, the drain pipe can in time discharge into city pipe network with the water of base below, avoids overstock volume too much to lead to the infiltration backward flow, and the general management water in the station also can be regarded as to the infiltration simultaneously.

Optionally, a waterproof layer is arranged on the inner side of the water baffle.

The waterproof layer can cover the water baffle plate while further preventing water, and simultaneously covers the connecting bolt and the nut, so that the inner wall is more attractive.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a drain pipe of infiltration hole, connecting bolt, breakwater and base below on the concrete layer realizes the subway and secretly digs the waterproof and drainage water of station, has effectively solved the infiltration problem between rock-based layer and the concrete layer.
