Abstract
The invention provides a subway station anti-flooding tunnel which comprises a subway station foundation pit, a subway opening boss and a drainage system, wherein the subway station foundation pit is of an inverted trapezoidal structure, a plurality of diversion trenches are formed in two side walls of the inverted trapezoidal structure, and the diversion trenches on the same side are converged to a water storage pit; the two sides of the bottom of the inverted trapezoidal structure are provided with catchment channels which are communicated with the outside through water pumps; and a flow guide channel is arranged at the periphery of the lug boss of the subway entrance and is communicated with a sewer. Avoid in the rainwater gets into the tunnel, dredge the water conservancy diversion to outside water, the infiltration water is collected and is discharged, and the water that gets into collects and takes away, guarantees the safety of tunnel main body equipment.
Description
Technical Field
The invention relates to a tunnel structure, in particular to a subway flood-proof tunnel.
Background
The subway is usually arranged at a deeper underground position, rainwater must be isolated and protected, and damage caused by flooding of electrical equipment in the subway is avoided.
In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a subway flood-proof tunnel which is scientific in design, good in persuasion, clear in hierarchy and capable of preventing multiple stages.
In order to achieve the purpose, the invention adopts the technical scheme that: a subway station foundation pit is of an inverted trapezoid structure, a plurality of diversion grooves are formed in two side walls of the inverted trapezoid structure, and the diversion grooves on the same side are collected to a water storage pit; the two sides of the bottom of the inverted trapezoidal structure are provided with catchment channels which are communicated with the outside through water pumps; and a flow guide channel is arranged at the periphery of the lug boss of the subway entrance and is communicated with a sewer.
On the basis, the diversion trench is arranged corresponding to the parts of the station inlet channel and the station outlet channel.
Basically, the position of the water storage pit is positioned below the bottom of the inverted trapezoidal structure.
Basically, the delivery port of the pipeline that the suction pump is connected is the expansion end, and this expansion end department sets up level sensor, solenoid valve, singlechip and wireless module, the singlechip is relevant level sensor the solenoid valve with the start-stop switch of suction pump closes so that level sensor senses when the water level is too high the suction pump closes the solenoid valve sends alarm information for control center through wireless module simultaneously.
Compared with the prior art, the invention has outstanding substantive characteristics and obvious progress, and particularly, the invention arranges the diversion channel at the periphery of the external subway entrance boss, and the diversion channel is communicated with the sewer to divert most of rainwater away and prevent the rainwater from entering the subway entrance; a small amount of rainwater enters the subway entrance, a diversion trench is arranged on the side part of the inverted trapezoidal structure and collects the rainwater to a water storage pit, and the water storage pit is positioned at a deeper position, so that an emergency measure for avoiding water non-discharge caused by sewer congestion is taken; once the rainwater quantity is too big, set up catchment canal at the bottom of the trapezoidal structure of falling, catchment canal can build the form of underground river, and the rainwater collects to catchment canal, and subway key equipment is between two catchment canals, and inside water passes through the pump and reaches ground, as the last barrier in the subway, multistage protection, multistage dredging has solved most ponding problems that the subway faces basically.
Drawings
Fig. 1 is a schematic structural diagram of a subway flood-proof tunnel.
In the figure: 1. a foundation pit; 2. a subway entrance boss; 3. a flow guide channel; 4. a sewer; 5. a diversion trench; 6. a water storage pit; 7. a catchment channel.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
As shown in fig. 1, a subway station foundation pit 1, subway mouth boss 2 and drainage system, subway station foundation pit 1 is the trapezoidal structure that falls, water conservancy diversion passageway 3 is seted up to the periphery of subway mouth boss 2, water conservancy diversion passageway 3 intercommunication sewer 4, as the first barrier of outside, a large amount of rainwater that store up flows into sewer 4 through water conservancy diversion passageway 3.
A plurality of diversion trenches 5 are formed in two side walls of the inverted trapezoidal structure, the diversion trenches 5 are arranged corresponding to parts of the station inlet channel and the station outlet channel, the diversion trenches 5 on the same side are converged to a water storage pit 6, and the position of the water storage pit 6 is located below the bottom of the inverted trapezoidal structure. As a secondary barrier for the tunnel, the amount of water that can normally enter is minimal and is collected by the gutters into the impoundment basins 6, avoiding rain water to continue to enter the tunnel.
The bottom both sides of falling trapezium structure set up catchment canal 7, catchment canal 7 communicates the external world through suction pump (not drawn in the picture), and catchment canal is 7 and is the third protective screen, and when current twice protective screen was not enough to keep out the rainwater, it was huge to prove the rainfall volume, consequently, collects the rainwater to catchment canal after, in time takes out, avoids catchment canal to overflow.
The delivery port of pipeline that the suction pump is connected is the expansion end, and this expansion end department sets up level sensor, solenoid valve, singlechip and wireless module, the singlechip is relevant level sensor the solenoid valve with the suction pump open and stop the switch so that level sensor senses the shutdown when the water level is too high the suction pump is closed the solenoid valve sends alarm information for control center through wireless module simultaneously.
The purpose that the setting is the activity lies in, during the flood, the rivers direction is uncertain usually, and the delivery port of activity is more nimble, when outside rainwater accumulates too much, leads to drawing water and has pressure even when the rainwater flows backward, through level sensor response, closes the solenoid valve, closes the suction pump, sends out the police dispatch newspaper, informs relevant responsible personnel to adjust the position of delivery port expansion end as early as possible.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
