Formwork jumbo for full face construction of pipe gallery and construction method thereof

Abstract

The present invention relates to the technical field of engineering construction, and more particularly, to a formwork jumbo for full face construction of a pipe gallery and a construction method thereof. The formwork jumbo comprises a longitudinal beam, a formwork part, a formwork supporting device and hydraulic mechanisms. The formwork part comprises a top form, side forms and a bottom form. Each of two sides of the longitudinal beam is connected to one side of a distributive girder through one hydraulic mechanism. The other side of each distributive girder is connected to one side form. The top and the bottom of each of the side forms are connected to the top form and the bottom form, respectively. The middle section of the top form and the middle section of the upper portion of each side form are connected by a hydraulic mechanism, and so are the middle section of the bottom form and the middle section of the lower portion of each side form. The formwork jumbo is applicable to a full face pipe gallery construction technique. One-step formation through pouring of concrete is achieved, and the steps of construction joint treatment, stay bolt set-up and formwork removal in traditional formwork construction are omitted. The problem of water penetration through a construction joint is fundamentally solved. The formwork jumbo is more practical, more convenient, and prone to standardized management, and has enormous technical and economical benefits.

Description

[technical field] [0001] The invention relates to the technical field of engineering construction, in particular to a formwork trolley used for full-section construction of a pipe gallery and a construction method using the formwork trolley. [Background technique] [0002] In recent years, the construction of urban comprehensive pipe corridors has sprung up on a large scale. The cast-in-place construction of pipe corridors mainly adopts conventional loose formwork such as wood formwork, steel formwork, plastic formwork, and aluminum formwork. It requires a large number of formwork supports and other materials, which requires a lot of labor and low construction efficiency. , and there are many joints in the formwork, the appearance quality of the concrete is poor, and a large number of wall-penetrating tie rods are required for formwork support and fixation, which increases the hidden danger of underground structure leakage. There are also simple trolleys or self-propelled hy...
