Background
The environment-friendly society is a new human society development form characterized by environment friendliness, is a concrete expression form of sustainable development society, is a society of harmony between people and nature, and is necessarily a society of basic harmony between people. The goal of building an environmentally friendly society has been commonly accepted by the masses. At present, ecological environment protection is an important measure for building environment-friendly society in China. The building construction is one of the important factors for polluting the environment, so how to reduce the emission in the construction process and reduce the influence of the construction on the environment is a key problem to be solved at present.
In bridge construction in areas with high environmental protection requirements, even if the current most environmental-friendly assembly type construction mode is adopted, the destructive influence on the environment can be caused when equipment enters a field, the field is flat, foundation construction and temporary construction are carried out.
In the existing construction method with high environmental protection requirements for the bridge, the erection of the beam section can realize construction without falling to the ground through the techniques of hanging baskets, bridge erecting machines and the like, so that the influence on the surrounding environment is reduced to the greatest extent. But mechanical equipment ground operation is still commonly adopted for pile foundation or bearing platform construction of bridge structures, pile driving construction is carried out, and bearing platform pouring is carried out. In the process of equipment ground operation, the vehicles and equipment enter and exit the site continuously, so that the natural environment of the area beyond the construction red line is greatly influenced.
In the field of known technology, the construction technology of the bridge structure which has no influence on the periphery is limited at present. In the patents with publication numbers CN10150923012, CN10158107312, CN10295334311, CN10412065912, CN10583954812, CN10590862912, CN201010860Y, CN201873946U, CN202000263U, CN202416191U, CN202482775U, CN204174537U, etc., the so-called down-travel mobile construction equipment is construction equipment for a girder structure, such as a bridge girder erection machine, a cradle, etc., and no mention is made of construction equipment for other parts of the bridge structure except the girder structure.
The pile integrated structure disclosed in the patent publication numbers CN201620644167 and CN201610467070 is a pile-striding type non-falling construction steel platform structure, and although the technical problem of pile foundation non-falling construction is solved to a certain extent, the structure disclosed in the patent is limited to the construction of precast concrete pipe piles, and the construction of a filling pile structure which is most widely applied to the current bridge cannot be performed; meanwhile, the steel platform in the patent needs to be moved to continuously disassemble and assemble the pile cap structure, large hoisting equipment is needed to be matched, autonomous movement cannot be carried out, and technical advantages are lacking in construction speed.
At present, a main platform used as a lower structure is mainly supported by steel pipe piles, and a bailey piece is erected on the surface of the trestle, so that a construction platform can be provided for bridge lower structure construction, but the construction platform cannot be moved, is difficult to turn over, needs to be provided with other construction equipment, and can also have a certain influence on the surrounding environment during construction of the trestle structure.
