Abstract
The utility model relates to a safety device used in the construction of a tunnel, in particular to a suspended safety isolator used in the construction of a tunnel shaft, which aims to solve the problems that the blasting operation during the secondary well completion construction of a conventional tunnel shaft affects the tunnel lining operation conducted at the same time, the safety of the operators is difficulty to guarantee, the falling objects in the tunnel lining operation cause danger to safety of the tunneling operators at the lower layer. The suspended safety isolator used in the construction of the tunnel shaft comprises a support steel beam arranged inside a reserved wall seat and an isolation network located below the support steel beam. Fixed pulleys are arranged at the lower side of the support steel beam and the upper side of the isolation network, and a winch is fixed at the upper side of the isolation network. A steel wire rope which is connected with the winch and the support steel beam and goes round the fixed pulleys is connected between the winch and the support steel beam. The suspended safety isolator is reasonable and reliable in structural design, and the original reverse asynchronous operations of tunneling and lining are changed to be homonymous synchronous construction, so the work efficiency is greatly improved, the construction period is shortened. Meanwhile, the suspended safety isolator is safe, has remarkable benefits of saving energy and protecting the environment and has the advantages that the suspended safety isolator is easy to realize, convenient to control and is low in cost.
Description
Technical field
The utility model relates to constructing tunnel and uses safety device, is specially a kind of tunnel shaft construction and uses the suspension safety insulating device.
Background technology
Speedway is grown up after the tunnel is open to traffic; Can be detained a large amount of harmful vehicle exhausts in the hole; Need to adopt venting practice to eliminate; Open vertical discharge flue---vertical shaft earthward at the middle part, tunnel, shaft section area is separated into smoke evacuation and air intake two parts, airshaft is to use more ventilation form at present.
Positive well method is adopted in the vertical shaft construction mostly, and the driving that promptly certainly faces down is Zheng Dong to the tunnel, carries out the reinforced concrete lining layer of pit shaft more from bottom to top.There are problems such as work efficiency is low, long in time limit, energy consumption is high, security risk height in positive well method.
Problem to positive well method construction existence; Developed secondary Cheng Jingfa; Promptly the downward preboring deslagging hole at the vertical shaft center forms vertical deslagging passage, will promote muck removal originally and change horizontal muck removal mode in the positive hole into; Make the reverse substep operation of original driving and lining cutting become synchronization job in the same way, the purpose that reaches the reduction of erection time, cuts down the consumption of energy, reduces security risk, practices thrift construction cost.
In secondary Cheng Jingfa, driving is constructed with lining cutting synchronously, and close together can be brought certain influence to the workman of top lining cutting operation when explosion is implemented in the bottom, and constructor's safety is difficult to ensure.
Summary of the invention
Lining cutting operation, the constructor's safety that the explosion influence was carried out synchronously when the utility model adopted secondary Cheng Jingfa construction in order to solve the existing tunnel vertical shaft is difficult to ensure and the problem that thing jeopardizes lower floor's driving personal security is weighed down in two lining constructions, provides a kind of tunnel shaft construction to use the suspension safety insulating device.
The utility model is to adopt following technical scheme to realize: the suspension safety insulating device is used in the tunnel shaft construction; Comprise and be arranged on support girder steel of reserving in the wall seat and the isolation rack that is positioned at support girder steel below; Support the girder steel downside and be provided with fixed pulley with isolation rack upside; And isolate the rack upside and be fixed with hoist engine, be provided with the wire rope that is connected and walks around fixed pulley with both between hoist engine and the support girder steel.
Slungshot through isolation rack protection explosion causes utilizes hoist engine and fixed pulley pulling wire rope simultaneously, and then drives the up-down of isolation rack, rises to certain altitude so that in time will isolate rack before the explosion.
During operation, after one section lining cutting is accomplished, should place the quick-fried scope of operation of brill with isolating rack decline earlier, with the folding interim firm supporting of supporting leg; Utilize well head ground lifting means to cooperate and remove the support girder steel; And move down at the reservation wall seat place of low one deck and reinstall the support girder steel; Rearrange fixed pulley group wire rope; Accomplish to isolate the in place again of rack, overcome that the explosion influence was carried out synchronously when the existing tunnel vertical shaft adopted secondary Cheng Jingfa construction lining cutting operation, constructor's safety are difficult to ensure and the problem that things jeopardize lower floor's driving personal security is weighed down in two lining constructions.
The isolation rack is made up of isolation skeleton and the gauze wire cloth that is fixed on isolation skeleton upper and lower surfaces, and the edge that isolates rack has protective door, is fixed with cat ladder on the isolation rack below the protective door.
The structure design of isolating rack stops blasting flyrock, and reaches the purpose of security protection by the energy that the elasticity of gauze wire cloth absorbs slungshot, for boring quick-fried work plane good ventilation, daylighting condition is provided simultaneously; The convenient construction personnel that are provided with of protective door and cat ladder are current.
The utility model reasonable in design is reliable; Make the reverse asynchronous construction of original excavation operation and lining cutting be improved in the same way construction synchronously; Work efficiency, reduction of erection time have greatly been improved; The benefit of subsidiary simultaneously significant safety, energy-saving and environmental protection has and is easy to realize, is convenient to control and advantage that cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-reserves the wall seat, and 2-supports girder steel, and 3-isolates rack, 4-fixed pulley, 5-hoist engine, 6-wire rope, 7-protective door, 8-cat ladder.
The specific embodiment
The suspension safety insulating device is used in the tunnel shaft construction; Comprise and be arranged on support girder steel of reserving in the wall seat 12 and the isolation rack 3 that is positioned at support girder steel 2 belows; Support girder steel 2 downsides and be provided with fixed pulley 4 with isolation rack 3 upsides; And isolate rack 3 upsides and be fixed with hoist engine 5, be provided with the wire rope 6 that is connected and walks around fixed pulley 4 with both between hoist engine 5 and the support girder steel 2.Isolation rack 3 is made up of isolation skeleton and the gauze wire cloth that is fixed on isolation skeleton upper and lower surfaces, and the edge that isolates rack 3 has protective door 7, is fixed with cat ladder 8 on the isolation rack 3 of protective door 7 belows.
In the practical implementation process, supporting girder steel 2 is to be supported by the groined type girder steel, provides support counter-force by reserving wall seat 1, because of the length of groined type girder steel less than the vertical shaft diameter, only need that level is traversing can conveniently remove to the vertical shaft diametrical position; Isolating rack 3 is made by vertical, horizontal steel I-beam and two-layer up and down protective screening.
