Problems solved by technology

The present invention improves the above-mentioned problems, that is, the technical problem to be solved by the present invention is that when the power transmission line iron tower is operated on-site, the conventional marine construction method that adopts ship construction in environments such as tides, tidal flats, and marine affairs will be easily affected by the ebb and flow of the tide. Ships are easy to run aground, the construction cost is high, and the effective construction time of the tower foundation is limited, which seriously affects the project quality and construction period

Abstract

The invention provides a method for realizing offshore mudflat tower foundation construction on the basis of a trestle method. The method comprises steps as follows: steel trestles are constructed sequentially, then tower foundation construction platforms are arranged, and then the steel trestles are dismounted. According to the method, the steel trestles are erected between a sea wall and a towerposition, an auxiliary steel trestle construction operation platform is erected at the tower foundation, the influence caused by field operation environments such as tides, mudflats, maritime affairsand the like can be effectively solved, then the engineering construction quality as well as completion and production as scheduled can be effectively guaranteed, longitudinal steel pipes are connected through transverse connecting rods or inclined rods, upper structures of the steel trestles are connected through transverse connecting rods or inclined rods, the structure is a whole, and the stability of the structure is enhanced. The steel trestles are simple in structure; the molded structure is relatively easy to mount and dismount, so that the construction period is greatly shortened; thetower foundation is good in overall stability and high in the carrying capacity, and construction machinery can pass through or operate on the tower foundation conveniently; the labor intensity is low, the work efficiency is high, the cost is relatively low, the tower foundation is environment-friendly and energy-saving, the safety risk is low, and no application precedent exists in offshore mudflat tower foundation construction for domestic transmission line engineering.

Description

technical field The invention relates to a method for realizing the foundation construction of coastal flats based on the trestle bridge method. Background technique The entire route of the transmission line project needs to design multiple iron towers. Sometimes the foundation of the iron towers is located on the tidal flats outside the sea embankment. When the tide is high, the water depth is high, and when the tide is low, the base of the tower is exposed. It is extremely difficult. The conventional offshore construction method of using floating boats to set up auxiliary platforms or ships is easily affected by the ebb and flow of tides, ships are easy to run aground, and the construction cost is high. The effective construction time of the tower base is limited, which seriously affects the quality of the project and construction period. Contents of the invention The present invention improves the above-mentioned problems, that is, the technical problem to be solved b...
