All-hydraulic tunnel inverted arch trestle-type moving die frame

Abstract

The invention relates to an all-hydraulic tunnel inverted arch trestle-type moving die frame which comprises a main bridge, a front ramp bridge and a rear ramp bridge. The main bridge is provided with multiple span travelling devices from front to rear; the span travelling device comprises a pair of height regulating mechanisms and a pair of travelling mechanisms; the external side of the main bridge is at least provided with a pair of vertical die locating mechanisms, a pair of vertical die stripping mechanisms and a pair of vertical arc templates; and the bottom of the main bridge is provided with a gutter template device. According to the invention, the all-hydraulic tunnel inverted arch trestle-type moving die frame can rapidly and safely span the excavated surface of the inverted arch through the span travelling devices so that the work efficiency is increased; the vertical die locating mechanisms realize the rapid locating of the vertical arc templates so as to ensure no shift of the vertical arc templates when concrete is poured; the vertical die stripping mechanisms realize the stripping and collecting of vertical dies so that the manual transport time is reduced and the space is saved; and the gutter template device increases the utilization rate of the gutter template and the construction standardization. The all-hydraulic tunnel inverted arch trestle-type moving dieframe realizes the one-time construction of inverted arch lining, inverted arch filling and central gutter separation without disturbing the working procedures at the same time.

Description

technical field [0001] The invention relates to a fully hydraulic tunnel inverted arch trestle type mobile formwork, which includes a main bridge, a front slope bridge and a rear slope bridge. A plurality of crossing walking devices are arranged on the main bridge from front to back, and the crossing walking devices include a pair of height adjustment mechanism, a pair of walking mechanisms; the outside of the main bridge is provided with at least a pair of vertical formwork positioning mechanisms, a pair of vertical formwork removal mechanisms, and a pair of arc-shaped vertical formwork; the bottom of the main bridge is provided with a gutter formwork device. Background technique [0002] In traditional tunnel inverted arch construction, vertical formwork is required when pouring concrete on the low side wall. The traditional method of erecting formwork for low side walls uses arc-shaped formwork or combined steel formwork. These traditional methods have the following defec...

AI Technical Summary

Problems solved by technology

The traditional method of erecting formwork for low side walls uses arc-shaped formwork or combined steel formwork. These traditional methods have the following defects: a large number of steel bars, steel pipes, iron wires, etc. are required to assemble and reinforce the formwork when erecting the formwork, and most of these materials are in the pouring process. If it is left in the concrete, the consumption of auxiliary materials is large and the construction cost is high; the on-site assembly of the formwork piece by piece is time-consuming, labor-intensive, and the effect is extremely slow and the labor cost is high; It is effectively guaranteed that the frequency of mold running and explosion is relatively high

However, the mobile formwork of the inverted arch has the disadvantages of difficulty in walking, and the positioning and removal of the shaped mold is labor-intensive and time-consuming, and it cannot realize the one-time construction of the inverted arch lining, inverted arch filling, and central water ditch.
