An environment-friendly construction method for downward self-propelled steel trestle bridge structure

Abstract

The invention provides an environment-friendly downward self-propelled steel trestle structure construction method. The environment-friendly downward self-propelled steel trestle structure construction method specifically comprises the following steps that the height of vegetation on a construction line is measured; the construction of first two bridge piers is completed, and lifting equipment isinstalled; a main longitudinal beam is assembled; the main longitudinal beam is lifted, and brackets and a slip device are installed, and the main longitudinal beam is lowered to the slip device; an adjustable supporting system and a slip device are installed, a main longitudinal beam is lengthened, and a transverse connecting beam is installed; a movable crane and a mobile transporting trolley are assembled, an adjustable supporting system and a slip device are installed, a main longitudinal beam is lengthened, and a transverse connecting beam is installed; a construction workbench is erected, drilling machines are arranged for pile foundation construction; a bridge pier structure is constructed; an adjustable support system and a slip device are installed, and a main longitudinal beam isslipped; and an adjustable support system and a slip device are installed, and a main longitudinal beam is slipped. According to the environment-friendly downward self-propelled steel trestle structure construction method, the influence on the environment is reduced, the ground construction on a trestle structure is realized, and the safety of the structure is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an environment-friendly construction method for a downward self-propelled steel trestle structure. Background technique [0002] An environment-friendly society is a new form of human social development characterized by environmental friendliness. It is a concrete manifestation of a sustainable development society. The goal of building an environment-friendly society has been recognized by the general public. At this stage, doing a good job in ecological environment protection is an important measure for my country to build an environment-friendly society. And building construction is one of the important factors that pollute the environment. Therefore, how to reduce the emissions during the construction process and reduce the impact of construction on the environment is the key problem that needs to be solved at present. [0003] Bridge construction in areas with h...

[0006] The patents with the publication numbers CN201620644167 and CN201610467070 disclose a pile-column integrated structure cross-pile non-ground construction steel platform structure. It is limited to the construction of prefabricated concrete pipe piles, and the cast-in-situ pile structure, which is currently the most widely used bridge, cannot be constructed; at the same time, the movement of the steel platform in this patent requires continuous disassembly and assembly of the pile cap structure, and requires the cooperation of large hoisting equipment, so it cannot be moved independently , lack of technical advantages in construction speed

[0007] At present, the main platform for the construction of the substructure—the trestle structure is mainly supported by steel pipe piles, and the surface of the trestle is built with Bailey sheets. Although it can provide a construction platform for the construction of the substructure of the bridge, its structure cannot be moved and turnover is difficult, so it needs to be configured Other construction equipment, and the construction of the trestle structure will also have a certain impact on the surrounding environment
