Abstract
The invention discloses a construction method for integrally pouring inverted arch concrete by matching a trestle with a top formwork, which belongs to the construction method for pouring inverted arches concrete of tunnels and relates to the manufacture and utilization of top formworks and trestles. The construction method for integrally pouring inverted arch concrete by matching the trestle with the top formwork includes the steps of (1) manufacturing a top formwork structure; (2) manufacturing a trestle structure; (3) preparing: measurement locating, formwork locating, concreting and trestle displacing and positioning. The construction method for integrally pouring inverted arch concrete by matching the trestle with the top formwork is easy, capable of guaranteeing the concrete to be shaped as designed during the inverted arch concrete pouring process, and effectively guaranteeing the tunnel to be normally open to traffic during the inverted arch construction process.
Description
Technical field
The invention belongs to tunnel invert concrete pouring construction method, relate to the making and the use of backform and trestle, be specifically related to trestle and cooperate backform monobloc cast inverted arch concrete construction method.
Background technology
In the tunnel invert concrete pouring construction process, because of mostly inverted arch concrete shape is arc, and concrete slump is bigger, does not adhere to specification if the concrete profile of the very difficult control of backform is not installed.Simultaneously, for guaranteeing normally to be open to traffic in the inverted arch construction period hole, need above inverted arch, set up the inverted arch trestle.
So concrete can't be necessary to design special-purpose backform of a kind of tunnel invert concreting and trestle by the problem of design shape moulding in the tunnel invert concrete pouring construction process in order to solve.
Summary of the invention
The present invention is in order to solve the deficiency that above-mentioned prior art exists, and provides a kind of trestle to cooperate backform monobloc cast inverted arch concrete construction method.
The present invention realizes through following technical scheme:
Trestle cooperates backform monobloc cast inverted arch concrete construction method, may further comprise the steps:
(1) making of backform structure: use i iron to be welded into the backform main frame; Be connected through limit moulding oil top, bed die oil top, the backform structure oil top of going up and down between backform main frame and each template; The backform tail end is equipped with backform structure road wheel; Connect through rotating shaft between the wherein said template, described limit moulding oil top, bed die oil top, backform structure are gone up and down the oil top through being arranged on the flexible oily top of the backform control cabinet control between backform main frame and the template;
(2) making of trestle structure: be welded into the trestle girder with i iron; Trestle girder top welding trestle steel plate; The two ends of trestle girder connect the trestle ramp through the rotating shaft of trestle ramp, and the trestle supporting leg is installed, and the end of trestle girder is installed liftable trestle road wheel;
(3) preparation: after treating that the inverted arch concrete of having built reaches initial set, utilize the oil top to pack up two side templates, rise intermediate die plate again, the cleaning template is also brushed release agent;
Measurement and positioning: measure inverted arch center line and absolute altitude according to design; Treat that the inverted arch concrete reaches 90% o'clock of design strength; Fall backform structure road wheel, utilize plant equipment that the formwork structure leading portion is sling, drag formwork structure and be forwarded to the position of waiting to build inverted arch; Lay railway sleepers or the lumps of wood, pack up backform structure road wheel;
Template Location: according to measurement result intermediate die plate is dropped to design height, fix support screw, then that two side templates are in place, fix support screw;
Concreting: connect pumping concrete behind the pumping concrete pipe, mouth is pressed into concrete to the order of pumping concrete from the inverted arch both sides again for the pumping of concrete charging aperture on the middle template earlier is pressed into concrete, adopts the form vibrator that is installed on the template to vibrate;
Trestle displacement and in place: remove two plate inverted arch holes quarrel down,, treat to move the inverted arch trestle after a plate backfill concrete reaches design strength with quarrel body pile trestle front-end platform; Ramp, trestle two ends is dug folding, utilize the plant equipment trestle rear end of slinging, put down the trestle road wheel; The trestle girder front end of slinging drags before the trestle girder proceeds to quarrel body platform, lays railway sleepers or the lumps of wood; Put down trestle girder front end, front side trestle supporting leg is dropped on the sleeper, the trestle main beam rear end of slinging; Put down the trestle girder after packing up road wheel, at last the rotation of ramp, two ends is set level.
The inventive method is simple, can guarantee that concrete effectively guarantees normally to be open to traffic in the inverted arch construction period hole by the design shape moulding in the tunnel invert concrete pouring construction process.
