Abstract
The utility model discloses an integrated moving framework for an inverted arch of a tunnel. The integrated moving framework comprises an end head supporting frame and a side edge arched framework; the end head supporting frame comprises a tunnel bottom truss an at to two ends of the tunnel bottom truss; the side edge arched framework comprises a short side wall arched frame and an arc-shaped arch bottom framework which is hinged to the lower end of the short side wall arched frame; and the short side wall arched frame is fixedly connected to the side edge arched framework fixing frames through connecting rods. According to the integrated moving framework for the inverted arch of the tunnel, the inverted arch and a side wall are poured firstly; after the concrete poured in the inverted arch and the side wall reaches initial set, the arc-shaped arch bottom framework is turned to a vertical position, and then the concrete used for filling the inverted arch and the side wall can be poured, therefore, the time interval of pouring the inverted arch and the side wall is greatly reduced, and the pouring efficiency is high; simultaneously, the position of the short side wall arched frame can be conveniently adjusted by adjusting the length of the connecting rods, so that the short side wall arched frame can be conveniently and quickly positioned and fixed, and as a result, the construction efficiency can be further improved.
Description
Technical field
The utility model relates to a kind of tunnel invert and short side wall concrete formwork for placing, particularly a kind of tunnel monolithic inverted arch mobile formwork.
Background technology
Along with national in recent years the input energetically, particularly high-speed railway of infrastructure construction, the large tracts of land of passenger dedicated railway line construction are carried out.Limited by geologic condition, tunnel proportion in mountain route increases gradually.Conventional construction method is that the inverted arch framing is built, and builds the inverted arch fill concrete again after the final set of inverted arch concrete, and short abutment wall is cast separately also.For improving the application life and the structural safety in tunnel, at present inverted arch and short abutment wall adopt the monolithic one-time-concreting more during constructing tunnel, in tunnel monolithic inverted arch and the construction of short abutment wall, exist Template Location difficulty, inverted arch and the requirement of inverted arch fill concrete separately build blanking time long, build problems such as efficient is low.For guaranteeing that inverted arch and short abutment wall satisfy the construction quality requirement, it is quick, accurate, firm, easy to use to make a kind of location, can effectively raise labour efficiency, reduce the template of workman's operation intensity, and what just show is particularly important.
The utility model content
In view of this, the purpose of this utility model provides a kind of tunnel monolithic inverted arch mobile formwork, and Template Location difficulty, inverted arch and inverted arch fill concrete require separately to build length blanking time, build problems such as efficient is low in the construction to solve.
The utility model tunnel monolithic inverted arch mobile formwork, comprise termination bracing frame and side arch mould bases, described termination bracing frame comprises the tunnel bottom truss and is fixed on the side arch mould fixed mount at tunnel bottom truss two ends, described side arch mould bases comprises short abutment wall arched frame and is hinged on the arc arch bed die frame of short abutment wall arched frame low side that described short abutment wall arched frame is fixedly connected on the side arch mould fixed mount by connecting rod.
Further, described tunnel bottom truss comprises crossbeam, is fixed on the arc beam and the brace summer that is connected crossbeam and arc beam of crossbeam below;
Further, described side arch mould fixed mount comprises vertical beam that is fixed on the crossbeam end face and the raker beam that is connected vertical beam upper end and crossbeam;
Further, the adjustable length of described connecting rod, and the two ends of connecting rod are hinged on respectively on short abutment wall arched frame and the side arch mould fixed mount;
Further, described connecting rod is made up of sleeve pipe and two screw rods that are arranged at the sleeve pipe two ends.
The beneficial effects of the utility model: the utility model tunnel monolithic inverted arch mobile formwork, termination bracing frame and side arch mould bases link into an integrated entity, building inverted arch and abutment wall, after treating inverted arch and side wall concrete initial set, arc is encircleed the bed die frame turn to vertical position, can build inverted arch and abutment wall fill concrete, make shorten greatly both blanking times of building, build the efficient height; Can regulate the position of short abutment wall arched frame simultaneously by the length of regulating connecting rod easily, make that the location of short abutment wall arched frame and convenient fixing are quick, can further improve efficiency of construction.
