Problems solved by technology

Due to the large amount of riprap and the long transportation distance, and the gabion cannot be preserved on the inclined rock face, it needs to be surrounded by piling underwater, and the cost is huge; there is a caisson manufacturing site, and the caisson manufacturing cost is very high

Embodiment 1

[0012] The steel pipe pile platform in water is composed of support piles, flat joints, scissors braces, top beams, longitudinal beams and platform top pavement. Among them, the platform surface is made of small steel or steel bars and wooden boards, which are laid on the top transverse and longitudinal beams; the top transverse and longitudinal beams are supported on steel pipe piles as the main load-bearing beam; Connection, the scissor brace is connected obliquely to ensure the overall stability and torsion resistance of the platform.

[0013] 1. Chisel flat steel pipe pile foundation

[0014] Connect two small construction transport ships with section steel, reserve drilling positions between the hulls, and set up temporary floating platforms in the water. The floating platform composed of construction ships is preliminarily anchored at the platform position. The surveyors accurately stake out the platform pile positions, determine the position of the steel pipe piles on ...

Abstract

The invention relates to a method for putting up a steel pipe pile platform of an abrupt slope bare rock, and belongs to the technical field of bridge engineering construction. The method comprises the following steps of: planishing an abrupt slope at platform piles by using a churn drilling, so that the platform steel pipe piles are arranged; pre-embedding three positioning piles along the shoreside; connecting each of three platform steel pipe piles by using structural steel to form space triangular grids; connecting the platform steel pipe piles and the positioning piles by using the structural steel serving as a force transferring bar piece to form space triangular grids; arranging an underwater hinge joint diagonal bracing to enhance the rigidity and stability of the underwater platform steel pipe piles; and finally putting up the integral platform. The method has the advantages that compared with other conventional construction modes of caisson cofferdam or island cofferdam, themethod is convenient and quick, the constructional platform has a simple structure and is explicit in load bearing, all the steel pipe piles are turnover materials disassembled from other platforms without additional investments and can be recovered completely to realize the 'zero construction cost' of the platform, and the economic benefit is obvious; the scheme of putting up the platform is novel and simple, the construction period is short, and a process is easy to grasp; and the method is environmentally-friendly and pollution-free and has no backfills to an ocean.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering construction. Background technique [0002] The topography and geological conditions of the bare rock on the steep slope determine the particularity of the platform. In the current construction of the steel pipe pile platform on the steep slope in China, the gabion method is basically adopted, and the island caisson cofferdam is filled with soil to seal the pile position so as to To achieve waterless operation, and then blast flat inside to carry out drilling construction operations. Due to the huge amount of riprap and the long transportation distance, and the fact that the gabion cannot be preserved on the sloped rock face, pilings need to be piling underwater to secure it, and the cost is huge; there must be a caisson manufacturing site, and the caisson manufacturing cost is very high. Contents of the invention [0003] The purpose of the utility model is: to provide a steep slope...
