The invention has the advantages of effectively solving the problem of additionally erecting a die by manpower, ensuring the construction quality of the secondary lining, saving the die erecting time of the secondary lining, greatly improving the effect of the secondary lining construction and achieving remarkable effect of shortening the construction period of the whole tunnel building engineering.

Description

A kind of Tunnel Second Lining pouring procedure that has the tunnel lining trolley of plug-type end mould and finish
Technical field
The invention belongs to the technical field of tunnel construction process lining trolley, be specifically related to a kind of Tunnel Second Lining pouring procedure that has the tunnel lining trolley of plug-type end mould and finish.
Background technology
Increase along with expanding economy and population, the deficiency of traffic resource becomes restraining factors, current and expected future significant period of time, the construction of traffic aspect all will be concentrated one's energy to carry out in the China even the whole world, wherein the tunnel is one of of paramount importance approach of present transport solution, is all construction in too busy to get away tunnel of construction of urban traffic construction or Line for Passenger Transportation instantly, high-speed railway.In the tunnel construction process, mainly be divided into following four processing steps at present: (1) excavation, (2) initial stage temporary lining, (3) inverted arch is built, and (4) secondary lining is built.Wherein secondary lining is determining the quality of whole tunnel construction as its construction quality of final lining cutting, and the length of its construction period is also determining the cycle of whole tunnel construction engineering.
The casting method of secondary lining is mainly at present: utilize hydraulic lining trolley to form the hoop template, the lining trolley front end is general will build the lining cutting overlap joint certain-length formation closed end of finishing with a last Pin, the follower head of lining trolley is an open type, the assembly unit that needs the constructor to carry out independent template voluntarily forms the follower head blind end, after all termination sealings, injected hole by lining trolley, slip casting in enclosure space, after treating that concrete reaches certain intensity, building of next Pin lining cutting carried out in the beginning demoulding and reach.This method is the existing method that generally adopts substantially, also is the most advanced lining construction method.But this job practices drawback is obvious: (1) follower head needs manually to carry out with the assembly unit of wood chipboard block-by-block, thus this method closure very poor in the process of building the spillage excreting water phenomenon serious, have a strong impact on the lining construction quality; (2) because the follower head template needs the block-by-block assembly unit, often need for a long time, consuming time serious, seriously delay the duration.
Summary of the invention
The present invention provides a kind of Tunnel Second Lining pouring procedure that has the tunnel lining trolley of plug-type end mould and finish in order to solve the problems referred to above that the existing tunnel Second Lining Construction exists.In the process that Tunnel Second Lining is built, lining trolley carries the follower head template that can stretch, advances the follower head template according to the section size of backbreaking, and makes template compress geotextiles and waterproof lamellar, directly build then, with automation, the mechanization that reaches the termination formwork erection.Guarantee construction quality, shorten the construction period, make lining trolley more convenient rationally simultaneously.
The present invention adopts following technical scheme to realize:
The tunnel lining trolley that has plug-type end mould, comprise lining trolley, be welded with some adjacent guiding steel frameworks on the circumferencial direction of lining trolley follower head periphery successively, the interior setting of each guiding steel framework is its its fixing faces end head plugging steel form relatively that slides also relatively.
Faces end head plugging steel form upper side is provided with waveform along toothing, is equipped with the hold-down bolt perpendicular to the faces end head plugging steel form on the upper ledge face of guiding steel framework, and the upper ledge face bottom of guiding steel framework is provided with reverse non-return device.Oppositely non-return device comprises the check steel plate that is articulated in guiding steel framework upper ledge face bottom, hinged handle lower end, the lower end of check steel plate, and the handle upper end passes the upper ledge face of guiding steel framework.Be provided with rubber weather strip around the faces end head plugging steel form.
A kind of Tunnel Second Lining pouring procedure, it adopts the above-mentioned tunnel lining trolley that has plug-type end mould to finish, its step is as follows: after lining trolley puts in place, pushing faces end head plugging steel form to faces end head plugging steel form continuously compresses tunnel surrounding and canvas cloth, tighten hold-down bolt then, and making reverse non-return device be fastened in waveform along toothing, concreting in the secondary lining space of the sealing that faces end head plugging steel form and lining trolley panel form forms Tunnel Second Lining.
The present invention has following beneficial effect: the present invention utilizes plug-type follower head template to form to have the new-type lining trolley of termination sealing template, efficiently solve a current difficult problem that still adopts artificial extra formwork erection, effectively guaranteed the construction quality of secondary lining, saved the formwork erection time of secondary lining, improved the effect of Second Lining Construction greatly, there has been remarkable effect the duration that shortens whole tunnel construction engineering.This method adopts simple plug-type termination template, the tunnel cross-section unfixed construction actual conditions of size of backbreaking there is great compliance, termination template among the present invention can reuse cheap with chassis, simple to operate, the benefit effect is obvious, particularly outstanding, of far-reaching significance in current extensive its economic benefit of bored tunnel construction field and social benefit, high promotional value is arranged.
