Abstract
The invention discloses an emergency airtight door used for connecting passage construction. The structure of the emergency airtight door comprises a door frame and a door body arranged in the door frame. The key improvement of the emergency airtight door lies in that: the door frame is arranged on a fan-shaped support body which is pre-arranged on a shield tunnel segment; upper and lower two sides of the door body are provided with pulleys which are matched with slide rails arranged on the upper and lower two sides of the door frame for sliding; and a servo mechanism used for controlling the movement of the door body is arranged between the door frame and the door body. The emergency airtight door has the advantages that: the emergency airtight door is arranged on the inner wall of the shield tunnel segment of a built tunnel corresponding to an excavation position of the connecting passage, and can separate the connecting passage from the built tunnel under emergency conditions such as collapse and the like so as to prevent a great deal of silt rushed into the built tunnel from endangering the safety of construction equipment and constructors; meanwhile, all the silt in the early collapse stays in the connecting passage, has the supporting function, and prevents continuously generating large-area collapse so as not to influence the safety of surface buildings; therefore, the economic loss of construction enterprises is reduced furthest.
Description
Technical field
The present invention relates to a kind of door of specific use, particularly the emergent hermatic door that uses in the construction of a kind of service channel.
Background technology
According to the requirement of subway design specifications; Whenever to build a service channel at least between the uplink of every subway and the downlink at a distance from 600 meters; It is in the metro operation process that service channel mainly acts on; Article two, fire or traffic accident if chance happens suddenly between the running tunnel can be played the effect of emergency evacuation passenger, assurance passenger safety.
Service channel (reality also is a cross dimensions and all very little tunnel of length) generally is after line running tunnel construction in the left and right sides finishes, just to begin to construct to the opposite side tunnel from a side tunnel; The service channel construction is a major hazard source in the subway construction process; Can not be effectively when emergencies such as many service channels take place to cave in the service channel in excavation and supporting process are arranged both at home and abroad with service channel and cut off at built tunnel; Thereby cause a large amount of silts to pour at built tunnel; The inner native balance of service channel is destroyed the large tracts of land landslide that is produced; Directly cause great safe mass accidents such as land subsidence, building destruction, established tunnel are buried, shield machine is submerged, constructor's injures and deaths, bring heavy economic losses to construction enterprises.
Can effectively block during situation such as, landslide permeable with service channel with between built tunnel in order to occur at service channel; Emergent hermatic door, is installed service channel on importing and exporting; And existing emergent hermatic door mostly is a plane structure, imports and exports difficult installation at service channel, even install successfully; Do not have sealing function yet, can not tackle the problem at its root.
Summary of the invention
Technical problem to be solved by this invention provides the emergent hermatic door that uses in a kind of service channel construction; When solving emergencies such as occurring landslide in the service channel construction with service channel and problem at the built tunnel partition; Protect safety effectively, reduce economic loss at built tunnel, constructor, construction equipment and above ground structure.
For realizing that the technical scheme that above-mentioned purpose adopts is: the emergent hermatic door that uses in the service channel construction; Comprise doorframe in its structure, be installed in the door body in the doorframe; Its key improvements is: doorframe is installed on the fan-shaped supporter that is arranged in advance on the tunneling shield section of jurisdiction; The pulley that the door body is provided with on the both sides up and down be arranged on doorframe up and down the slide rail on the both sides cooperates slip, be provided for controlling the servo control mechanism that a body moves between a doorframe and the body; The arc limit diameter of above-mentioned fan-shaped supporter is consistent with the tunneling shield section of jurisdiction; Fan-shaped supporter chord length equals the doorframe distance between the both sides up and down; Fan-shaped supporter is fixedly connected by means of the expansion bolt that is fixed on shield duct piece upper edge circumferential array; Comprise in the structure of fan-shaped supporter that steel being set in the middle of the fan-shaped steel plate of two block-shaped identical equidirectional settings, two fan-shaped steel plates supports, is arranged on the band steel on the fan-shaped steel plate arc limit; The length of band steel equals the arc length on fan-shaped steel plate arc limit, and the width of band steel equals two distances between the fan-shaped steel plate, is being provided on the band steel that fan-shaped supporter is installed in the installing hole on the shield duct piece.
Prime mover of above-mentioned servo control mechanism be installed on the doorframe vertical edges can be positive and negative the drive motors that rotates of both direction; Between drive motors and the door body lead-screw drive mechanism is set; A limit switch is respectively installed at the top of two vertical edges about doorframe; The management circuit that is used to control drive motors in door body top the right and left and the limit switch correspondence position installation limit switch contactor, limit switch and servo control mechanism is connected.
Prime mover of above-mentioned servo control mechanism is the drive motors that can positive and negative both direction rotates that is installed in body bottom; The pulley coaxle of the output shaft of drive motors bottom being arranged on a body is connected; A limit switch is respectively installed at two vertical edges tops about doorframe; The management circuit that is used to control drive motors in door body top the right and left and the limit switch correspondence position installation limit switch contactor, limit switch and servo control mechanism is connected.
Above-mentioned fan-shaped supporter has three, and its adjacent distance between any two equals a distance of body right ends, and limit, the doorframe left and right sides is connected with two fan-shaped supporters in the outside, and both sides are connected with three fan-shaped supporters respectively up and down.
Above-mentioned door body and the corresponding one side in doorframe four limits and middle fan-shaped supporter are provided with weather strip with the corresponding side of door body.
Adopt the beneficial effect that technique scheme produced to be: corresponding service channel excavation position is provided with emergent hermatic door on the shield duct piece inwall of established tunnel; During emergencies such as appearance landslide; Emergent hermatic door capable of using cuts off service channel and established tunnel; The safety of avoiding a large amount of silts to pour in established tunnel and destroying established tunnel, jeopardize construction equipment and constructor, the silt of initial stage landslide all rests on and can play a supporting role in the service channel simultaneously, can in service channel, keep the soil layer pressure balance; The safety of avoiding continuing to produce the large tracts of land landslide and influencing above ground structure, thus the economic loss of construction enterprises reduced to the full extent.
