Description

Dredging and draining system for station hall layers

Technical Field

The invention belongs to the technical field of a dredging system of a station hall layer of dredging systems, and particularly relates to a dredging system of a station hall layer of stations.

Background

With the acceleration of urbanization pace, urban population, regional planning and urban ecological environment face huge pressure, the development and utilization of urban underground space become a lot of concerned hotspots, and the development of a large-traffic fast public transportation system taking underground railways as the backbone is an important way to solve urban congestion. In recent years, urban rail transit engineering construction in China is developed vigorously.

The underground station is buried and underground and is soaked in underground water all the year round. Due to construction and annual service, concrete structures often crack, resulting in the leakage of groundwater into stations. Meanwhile, part of cleaning water in the station also remains on the station hall layer, the cleaning water accumulates day by day and month, more and more water is accumulated in the station hall, and if the cleaning water is not drained in time, the accumulated water soaks the cables and equipment in the pavement layer, so that adverse effects are generated on the cables. When the ponding is too much, can permeate medium plate construction joint or from the drippage of well hole edge to the platform layer of standing, influence the operation.

In the prior art, only the wall-separating wall is arranged, but the wall-separating wall is higher than the structural surface of the middle plate, and the floor drain is often blocked, so that the water accumulation of the middle plate is serious. The problems existing at present mainly include:

1. only set up from the wall ditch, and from the wall ditch water repellent back, the bottom surface is higher than medium plate structural plane, and the groundwater of side wall seepage can stretch to the medium plate if can't be got rid of smoothly, leads to medium plate ponding aggravation.

2. The middle plate has no drainage measure, accumulated water can only drip to the platform layer through a construction joint or a hole, and no targeted drainage measure is needed.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide kinds of station hall drainage systems capable of effectively draining water, which can achieve a good drainage effect.

In order to achieve the purpose, the invention is realized according to the following technical scheme:

kinds of station room layer dredge system, including along the station room side wall arrange from the wall ditch, with from the vertical drain pipe of wall ditch intercommunication, its characterized in that, dredge system still includes vertical drainage system, vertical drainage french drain, horizontal drainage french drain, vertical drainage french drain with horizontal drainage french drain is crisscross to be set up in the medium plate of station room, and vertical drainage french drain with horizontal drainage french drain communicates each other at the staggered point, vertical drainage system with it communicates with each other from the wall ditch.

Preferably, a plastic drainage blind ditch is arranged in the wall separating ditch along the length direction of the wall separating ditch, non-woven fabrics are wrapped outside the plastic drainage blind ditch to form a longitudinal drainage channel, and two ends of the transverse drainage blind ditch are communicated with the plastic drainage blind ditch.

Preferably, the longitudinal drainage blind ditch and the transverse drainage blind ditch are both plastic blind ditches.

Preferably, the wall separating ditch is made of concrete and is formed by pouring synchronously with the middle plate in the station hall.

Preferably, the vertical drain pipe is made of PVC or steel.

Preferably, the outer surface of the longitudinal drainage blind ditch and the outer surface of the transverse drainage blind ditch are both wrapped with non-woven fabrics

Compared with the prior art, the invention has the beneficial effects that:

1. in the utility model, as the drainage system of the water leakage inside the station hall formed by the longitudinal drainage blind ditch and the transverse drainage blind ditch is arranged in the middle plate, the cable and the equipment on the pavement layer are prevented from being soaked by the accumulated water of the middle plate, and the normal use of the equipment is prevented from being influenced;

2. the utility model discloses in, from setting up drainage blind pipe and drain pipe in the wall ditch, prevent that medium plate ponding water trickling from to the platform layer of standing, influencing the passenger.

3. The utility model discloses in, the blind pipe of plastic material is vertically set up along it from the inside edge of wall ditch of this application, advances steps and has prevented the infiltration to its outer surface parcel has the non-woven fabrics, can prevent the blind pipe damage.

Drawings

Embodiments of the present invention are described in further detail with reference to the drawings, in which:

fig. 1 is a schematic overall structure diagram of the station hall floor drainage system of the invention.

Fig. 2 is a partial cross-sectional view of the evacuation system of the lobby floor of the present invention.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

As shown in fig. 1 and 2, the drainage system of the present invention includes an off-wall trench ④ arranged along the side wall of the living room, a vertical drainage pipe ③ communicating with the off-wall trench ④, and a vertical and horizontal drainage system.

The longitudinal and transverse drainage system comprises a plurality of drainage blind ditches ① arranged in a middle plate ⑨, each drainage blind ditch ① comprises longitudinal drainage blind ditches and transverse drainage ditches which are arranged in a criss-cross mode, the longitudinal drainage blind ditches and the transverse drainage blind ditches are arranged in the middle plate of the station hall in a staggered mode, the longitudinal drainage blind ditches and the transverse drainage blind ditches are communicated with each other at staggered positions of the longitudinal drainage blind ditches and the transverse drainage blind ditches, the longitudinal drainage blind ditches and the transverse drainage blind ditches are plastic blind ditches, and non-woven fabrics are wrapped on the outer surfaces of the longitudinal drainage blind ditches and the outer surfaces of the transverse drainage blind ditches.

The plastic drainage blind ditch ② is arranged in the wall-separating ditch along the length direction of the wall-separating ditch, the plastic drainage blind ditch ② is wrapped with non-woven fabrics, the longitudinal drainage channel is arranged, the two ends of the transverse drainage blind ditch are communicated with the plastic drainage blind ditch, the inner wall of the wall-separating ditch ④ is also provided with a waterproof plastering layer
