Square block mounting and positioning method

Abstract

The invention discloses a square block mounting and positioning method, and relates to the technical field of wharf construction. The square block mounting and positioning method comprises the following steps of: 1, manufacturing a positioning frame and a positioning frame platform by using channel steel, angle steel or I-shaped steel; when the positioning frame is manufactured, a concrete base is arranged at the bottom of a positioning frame body, a crawling ladder and a measuring rod are arranged on the outer side of a stand column of the positioning frame body, and a connecting rod and a lifting lug are arranged at the top; 2, the manufactured positioning frames are hoisted underwater one by one to be installed, and in the hoisting process of the positioning frames, the positioning frames are positioned through a GPS; and step 3, installing the square blocks layer by layer from bottom to top by matching a crawler crane with a lifting appliance lifting rod. According to the square block installing and positioning method, the construction steps are simple, the square block positioning and installing precision can be greatly improved, the square block installing efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of wharf construction, in particular to a block installation and positioning method. Background technique [0002] A wharf is a naturally formed or artificially constructed long embankment that is primarily used for loading and unloading cargo or ship berths. Among the various structural forms of artificially constructed wharfs, gravity wharfs can withstand large ground loads and ship loads due to their strong and durable structure, good frost resistance and ice resistance, and can withstand large concentrated loads and wharf ground overloads. It is widely used because of its strong adaptability to changes in loading and unloading processes, simple construction and low maintenance costs. In the structure of artificially constructed gravity docks, blocks are widely used due to their small size (the length of concrete gravity blocks does not exceed 12m, the width does not exceed 3m, the height does not exceed...

AI Technical Summary

Problems solved by technology

[0003] One of the purposes of the present invention is at least to provide a method for installing and positioning blocks in order to overcome the inaccurate positioning of blocks in the installation process and low construction efficiency in the prior art. Auxiliary positioning improves the installation accuracy of the cube; the positioning and installation of the cube is carried out by using a positioning frame, a total station and RTK (Real Time Kinematic, real-time dynamic positioning) GPS equipment, which improves the installation accuracy and efficiency of the cube
