Integrally movable support formwork in underground utility tunnel construction, and construction method thereof

Abstract

The invention discloses an integrally movable support formwork in underground utility tunnel construction, and a construction method thereof. The integrally movable support formwork comprises an inner-side framework and an outer-side framework, wherein the inner-side framework is formed by splicing a top plate framework, two groups of inner wall frameworks and an inner-side support. According to the integrally movable support formwork disclosed by the invention, the inner-side framework is hoisted into a pit after being spliced outside the field, so that cumbersome erection work for a formwork support is avoided, and the inner-side framework and the outer-side framework are both movably located through a travelling frame, and then are subjected to the subsequent mold closing and reinforcement, so that the construction period is shortened, and the construction cost is lowered; and the inner-side framework is supported and reinforced through the inner-side support, so that the integral stability of an inner-side framework structure is ensured.

Description

technical field [0001] The invention relates to the field of construction of an underground comprehensive pipe gallery, in particular to an integral mobile support formwork and a construction method used in the construction of an underground comprehensive pipe gallery. Background technique [0002] With the development of economy, the expansion of urban scale and the continuous improvement of modernization, the urban underground pipe network is becoming larger and denser, and its types are becoming more and more diverse. Compared with the rapid development of the urban underground pipeline network, the management of the urban underground pipeline is lagging behind. It can no longer meet the growing demand of the pipeline network business, and restricts the development of the city to a large extent. At present, Guangxi, Shandong, Sichuan and many other places have launched underground pipe gallery construction projects, and the construction of underground pipe gallery in my c...

Problems solved by technology

[0003] At present, in the construction of underground pipe corridors, the main structure is mostly constructed with square wood and formwork with a steel pipe support system. However, ordinary formwork support has many construction procedures, long installation and dismantling time, high rental cost of steel pipe support, and wooden formwork turnover. It is difficult to guarantee the construction quality in the future
