Construction method for integrally translating box culvert full framing

Abstract

The invention discloses a construction method for integrally translating a box culvert full framing. The method specifically comprises the following steps: erecting the full framing at a cast-in-placebox culvert section part to be constructed; fixedly installing a box culvert formwork on the full framing, and carrying out steel bar binding and concrete construction of box culvert sections; carrying out maintenance of box culvert segment concrete is conducted to guarantee that the structural concrete strength meets the design and specification requirements; withdrawing the inner side mold backshore, and enabling the side mold plate to be naturally loosened; lifting the full framing and the box culvert template by using a jack, adjusting a bottom support, and moving the full framing to thenext box culvert construction section by using a traction device through pulling a traction frame; and dismounting a roller set and guide limiting rollers, and carrying out fixed supporting and subsequent box culvert segment construction onthe box culvert formwork. The construction method has the beneficial effects that the tool equipment is novel, the construction period is shortened, the formwork assembling quality is easy to control, and economy and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for the overall translation of the box culvert full support. Background technique [0002] The integral cast-in-place method of the full-wall bracket is a relatively common construction method in engineering construction and is widely used. In recent years, with the rapid development of my country's infrastructure construction, more and more projects have been designed according to the construction design of the full hall support, which has greatly promoted the application process of the full hall support, and the construction technology of the full hall support has also been continuously improved. [0003] The current construction technology of mantang support is also developing towards the direction of large tonnage and large span. The support steel pipe has been greatly improved in terms of material selection, pipe diameter increase, pipe...

Problems solved by technology

[0003] The current construction technology of mantang support is also developing towards the direction of large tonnage and large span. The support steel pipe has been greatly improved in terms of material selection, pipe diameter increase, pipe wall thickening, and connection method refinement; but for the support Most of the construction still adopts the construction cycle of erecting and dismantling, breaking parts into wholes and breaking them into parts, an
