Formwork transfer trolley for construction of shed tunnel lining arched part and construction method

Abstract

The invention relates to a formwork transfer trolley for construction of a shed tunnel lining arched part and a construction method. The formwork transfer trolley for construction of the shed tunnel lining arched part comprises a pouring formwork, a supporting truss, a mobile flat car and a track assembly, wherein the pouring formwork is fixedly connected to the working face of the supporting truss, and the supporting truss is mounted on the mobile flat car; when in a walking state, the mobile flat car is fixedly mounted on the track assembly on the ground and walks, a jack is mounted betweenthe mobile flat car and the ground during formwork mounting and concrete pouring and connected with a hydraulic station through a hydraulic pipeline, and a supporting seat is arranged between the mobile flat car and the ground. The formwork of the half-arch column type shed tunnel lining arched part can be wholly mounted and dismounted and wholly hoisted and moved, so that repeated formwork assembling and splitting work can be omitted, a tedious process of constructing scaffold protection can be greatly removed, the formwork can be entirely transferred to the next construction section, the processes of dismounting and mounting are omitted, construction efficiency is greatly improved, and construction period is shortened; and the formwork transfer trolley has the characteristics of high construction safety coefficient, rapidness, convenience, standardization and the like.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a mold-moving trolley and a construction method for construction of a shed tunnel lining arch, which are suitable for concrete construction of a shed tunnel lining arch. Background technique [0002] In recent years, my country's highway infrastructure has developed rapidly, a large number of highways are under construction or planned to be constructed, and high-grade highways have been promoted from plain areas to mountainous areas on a large scale. In highway construction, more and more road sections will be dug deep. In these road sections, for some areas with unstable slopes and steep slopes, general slope protection is difficult to achieve economical and long-term protection effects. It also has the advantages of simple construction technology, simple structure, and short construction period. Therefore, semi-arch column sheds with relatively stable structures ...

AI Technical Summary

Problems solved by technology

The labor intensity of this construction method is high, the construction efficiency is very low, and the progress is slow.

In order to meet the requirements of construction progress and construction period objectives, it is often necessary to increase the number of formwork, increase the number of operators and operating points to achieve it, which greatly increases the amount of brackets and formwork, and greatly increases the construction cost.

Moreover, the formwork has been repeatedly installed and disassembled piece by piece, the formwork is easily deformed, the deformation is large, and the joints of the plates are gradually deformed, so that the surface of the wall of the shed cave lining arch after pouring will be uneven after the formwork is removed, and the joints will leak. Cellular voids, resulting in poor appearance

Moreover, even if the honeycomb cavity is treated twice, the waterproof ability and structural durability of the shed cavity lining arch at this position will be greatly weakened.

Moreover, the integrity of the steel pipe support structure is poor, the bearing capacity is limited, and the construction safety risk is high when used in a heavy-loaded structure, and it is difficult to control
