Abstract
A cross-river section subway tunnel flood prevention emergency gate is provided; in a cross-river section subway tunnel application process, the river water may backflow to the subway tunnel because of construction design defects or force majeure factors, thus causing the river water to randomly flow in the through subway tunnel, and causing immeasurable disasters. Two ends of the cross-river section subway tunnel are provided with the flood prevention emergency gates; when the water level in the flood prevention emergency gate installation positions on two ends of the cross-river section subway tunnel exceeds certain value, the flood prevention emergency gate can automatically isolate the subway tunnel so as to stop river water from backflowing into the tunnel.
Description
Art
The present invention relates to rivers section subway tunnel flood control emergency closure, wore owing to the most a lot of subway tunnels have under river bed, the Congjiang
Situation about crossing, crosses rivers section subway tunnel and in use may encounter because of the design and construction factor such as defect or act of god
Cause the water inside rivers to pour in down a chimney into subway tunnel, but subway tunnel is mutually communicated again, so priming charge may pass through
Through tunnel flowing causes immeasurable disaster.This is crossed rivers section subway tunnel flood control emergency closure Main Function and is to work as river
Emergency closure of controlling flood when water in river pours into subway tunnel can start partition subway tunnel immediately and stop the water in subway tunnel to continue
Flow with stop disaster continue expand, the invention belongs to subway tunnel field.
Background technology
Along with the quickening of urbanization process, the available space of China's urban ground is fewer and feweri, and road traffic is more and more crowded,
In order to solve an above difficult problem, the most effectively utilize and create the underground space have become as current urban modernization build important topic.
Show, by the end of the year in 2012, Beijing, Shanghai, south according to the reply of each province and city Committee of Development and Reform and each province and city subway group company website
Capital, Guangzhou, Chongqing, Tianjin, Hangzhou, Wuhan, Chengdu, Xi'an, Shenyang, Changsha, Nanchang, Nanning, Dalian, Ningbo
Building etc. domestic more than 20 cities or preparing to build and new rail line in planning, circuit overall length more than 5000 kilometers,
Expecting the year two thousand fifty Chinese city rail line overall length will be more than 10000 kilometer, and a lot of subway tunnel has from rivers
Under situation about passing, therefore carry out due to the design and construction factor such as defect or act of god cause the water inside rivers pour in down a chimney into
Emergency during subway tunnel seems and is highly desirable to.
Summary of the invention
In order to overcome rivers section subway tunnel in use owing to the design and construction factor such as defect or act of god causes rivers
The water of the inside pours in down a chimney into subway tunnel, thus causes river random flowing inside through subway tunnel to cause immeasurable
The problem of disaster.The present invention provides and crosses rivers section two ends installation flood control emergency closure at subway tunnel, when crossing rivers at subway tunnel
The water level of flood control emergency closure position is installed when exceeding certain value in section two ends, flood control emergency closure automatically start partition subway tunnel with
The water in rivers is stoped to continue to pour in down a chimney.
The technical solution adopted for the present invention to solve the technical problems is: this is crossed rivers section subway tunnel flood control emergency closure and is arranged on
Subway tunnel crosses rivers section two ends, installs a water level exciting switch, when water level reaches certain early warning on flood control emergency closure limit
Emergency closure of controlling flood after value starts partition subway tunnel automatically to stop the water in rivers to continue to pour in down a chimney.
The invention has the beneficial effects as follows: when crossing rivers section subway tunnel due to the design and construction factor such as defect or act of god initiation
When river pours in down a chimney into subway tunnel, the river section of the mistake subway tunnel emergency closure excessively of the present invention can start Guan Bi, effectively automatically
Stop disaster continue expand, alleviate accident occur time personnel and property loss.
Accompanying drawing explanation
Fig. 1 was rivers section subway tunnel flood control emergency closure detail drawing.
Fig. 2 is rail and gate contact site detailed treatment detail drawing in Fig. 1.
Claims (2)
1. crossing a rivers section subway tunnel flood control emergency closure, its characteristic is, has served as flood control emergency closure when rivers section subway tunnel generation river pours in down a chimney and can automatically start Guan Bi, to stop expanding of disaster.
Rivers section subway tunnel flood control emergency closure of crossing the most according to claim 1 was arranged on the both sides of rivers section subway tunnel, a water level exciting switch is installed on flood control emergency closure limit, when the water level crossing installation flood control emergency closure position, rivers section two ends at subway tunnel exceedes certain value, exciter starts, and flood control emergency closure automatically starts partition subway tunnel and continues to pour in down a chimney with the water in prevention rivers.
