Abstract

The invention provides a pile block structure of a steel trestle and a steel trestle reinforcing method and belongs to the field of construction of steel trestles. A foundation pile group comprises atleast two steel pipe piles distributed in a spaced manner, wherein one end of each steel pipe pile is inserted into the ground while the other end of the steel pipe pile forms a supporting end for mounting a bearing platform. A mounting table is fixedly arranged on the surface, far away from the ground, of the bearing platform. The bearing platform comprises a first edge beam and a second edge beam arranged in parallel. The first edge beam is fixedly connected to one sides of all the steel pipe piles and the second edge beam is fixedly connected to the other sides of all the steel pipe piles.A Bailey truss is erected on the mounting table, and a top plate is fixed to the end, far away from the mounting table, of the Bailey truss. Working holes where a drill pipe of a drilling machine penetrates are formed in the top plate, the working holes correspond to the steel pipe piles, and a mounting part for mounting a drilling machine body is further arranged around the working holes. The pile block structure of the steel trestle can provide a drilling machine mounting position. The connecting strength of the steel pipe piles to the ground is improved as the drilling machine drills the ground to reinforce in real time.

Description

technical field [0001] The invention relates to the field of steel trestle construction, in particular to a steel trestle pile top structure and a steel trestle reinforcement method. Background technique [0002] The underwater steel trestle is a temporary structure commonly used for underwater foundations, and it is very important to ensure the stability of the steel pipe piles of the trestle. In areas with no or light coverage, see figure 1 , figure 2 with image 3 , the commonly used method is to use reinforced concrete anchor piles to connect the steel pipe piles with the bedrock. Contents of the invention [0003] The invention provides a steel trestle pile top structure and a steel trestle reinforcement method, aiming at solving the above-mentioned problems existing in the steel trestle pile top structure and the steel trestle reinforcement method in the prior art. [0004] The present invention is achieved like this: [0005] A pile top structure of a steel tr...
