Abstract
The invention relates to assembly of well covers, in particular to a method for assembling an escape well cover in a tunnel. The method comprises that: an opening is reserved on a tunnel structure first, and a bottom frame of the escape well cover in the tunnel is then fixedly connected to the opening; an upper cover is connected to the bottom frame; a power-assisted air pump is connected between the upper cover and the bottom frame; and one end of the power-assisted air pump is connected with the upper cover, and the other end of the power-assisted air pump is connected with the bottom frame. The method has the advantages that the escape well cover in the tunnel is controlled on the spot, has a simple structure and strong bearing property due to increase of the stability of the well cover, uses small force, is flexible and convenient to use, has the abilities of self-locking, creepage resistance and seepage resistance, and not only can be used on an escape scuttle in the tunnel but also can be used on an access hole.
Description
Technical field
The present invention relates to well lid class is installed, particularly relate to a kind of mounting method that is applicable to escape manhole in tunnel.
Background technology
Upper and lower pipeline and road surface manhole all will have stronger bearing capacity in urban construction, major part is the cast iron manufacturing, as folding paper well lid, anti-stealing manhole cover etc., present manual power-assisted well lid does not have shaped article at home, external product adopts stainless steel to make well lid and underframe, cost is high and do not have a large scale specification product, in existing various pipes and the road surface manhole, but the well lid that power-assisted is opened is rarely found, generally be to adopt electrical equipment or the large-scale well lid of hydraulic-driven, but system complex, it is high to safeguard that debugging requires, cost is higher, is difficult for promoting the use of.Therefore when running into emergency such as fire by escape way, when evacuate the emergency exit, occur well lid easily and be difficult for opening or do not open or phenomenon such as difficult sealing, can cause damage to personal property.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of mounting method of escape manhole in tunnel is provided, this method mainly comprises the fixing installation that reaches between loam cake and the underframe of reserved opening in underframe and the former tunnel, so that satisfy in the tunnel, require this escape manhole can be simultaneously by artificial safe, reliable, convenient opening to bearing, the steadiness requirement of well lid.
The object of the invention realizes being finished by following technical scheme:
A kind of mounting method of escape manhole in tunnel, comprise tunnel structure, it is characterized in that being that this method at first reserves opening on tunnel structure, afterwards at the underframe of the fixedly connected escape manhole in tunnel of opening part, be connected with loam cake on the underframe, between loam cake and underframe, connect the power-assisted air pump, one end of power-assisted air pump is connected with loam cake, and the other end is connected on the underframe.
Above-mentioned is fixedly connected, is to adopt expansion bolt or chemical anchor bolts that the lane plate structure in underframe and former tunnel is connected and fixed.Or underframe is embedded in advance in the lane plate structure in tunnel.
Cover on described lockset is installed, described lockset is provided with the unlatching handle in the upper and lower both sides of loam cake.
Advantage of the present invention is, field control, simple in structure, the steadiness that has increased well lid makes its bearing strong, use flexible, convenient, firmly little, have self-locking, anti-jump and certain percolation-proof ability, the well lid after the installation not only can be used for escaping exit place in the tunnel, also can be used for overhauling simultaneously current mouthful of place.
Description of drawings
Accompanying drawing 1 is the loam cake Unclosing structure schematic diagram of the present invention after installing;
Accompanying drawing 2 is mounted configuration schematic diagram of the present invention;
Accompanying drawing 3 is loam cake of the present invention bottom surface structural representation.
The specific embodiment
Feature of the present invention and other correlated characteristics are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-3, always representing respectively in the accompanying drawing: loam cake 1, underframe 2, power-assisted air pump 3, lockset 4, handle 5, dead bolt 6 with reference to label 1-6.
Embodiment one: the present embodiment mounting method is: at first reserve opening on the lane plate structure in tunnel, adopt expansion bolt or chemical anchor bolts that well lid underframe 2 is fixedly attached to tunnel structure at opening part afterwards.
Embodiment two: the difference of present embodiment and embodiment one is that underframe 2 is embedded in the lane plate structure in tunnel in advance.
The escape manhole that adopts the inventive method to install, have from all openable lockset 4 of upper and lower (track layer and passway for escaping), the combination of well lid and lockset makes well lid have anti-jump measure, prevent that loam cake is subjected to wheel load that the generation of spring or unexpected unlatching situation takes place, pressure wheel is crossed does not have the spring noise, does not influence the driving comfort.Open loam cake in the use, the power-assisted air pump can automatically be opened, and escape manhole can be by single light unlatching, and opening force is less than 15kg, and the well lid opening angle is greater than 90 degree, can prevent the well lid closure that glides rapidly after the unlatching.
Above-mentioned escape manhole load-bearing property is good, can satisfy the highway-I level load requirement among the JTG D60-2004 " highway bridge and culvert universal design standard ".Adopt the material of ductile iron, the agent structure wear-and corrosion-resistant as well lid and underframe.Well lid adopts and is fire proofing, reaches fire protection requirement.Well lid adopts the rubber strip sealing, has certain air-tightness and watertightness performance.
Claims (3)
1. the mounting method of an escape manhole in tunnel, comprise tunnel structure, it is characterized in that being that this method at first reserves opening on the lane plate structure in tunnel, afterwards at the underframe of the fixedly connected escape manhole in tunnel of opening part, be connected with loam cake on the underframe, between loam cake and underframe, connect the power-assisted air pump, one end of power-assisted air pump is connected with loam cake, the other end is connected on the underframe, covers on described lockset is installed, and described lockset is on loam cake, following both sides are provided with the unlatching handle, lockset is installed in and covers, utilize the rack-and-pinion transmission, 2 dead bolts of interlock control reach the function with underframe locking, lockset comprises rack and pinion drive, dead bolt and two unlatching handles are wherein opened handle and are connected the control dead bolt by rack and pinion drive.
