Open caisson perpendicularity detecting and adjusting device

Abstract

The invention discloses an open caisson perpendicularity detecting and adjusting device. The open caisson perpendicularity detecting and adjusting device comprises an open caisson, three infrared transmitting devices, three infrared receiving plates, jacks, coordinate systems, error allowance holes and quick sand filling layers. The three infrared transmitting devices are circumferentially and evenly arranged at the top of the open caisson, and the three infrared receiving plates are circumferentially and evenly arranged at the bottom end of the open caisson. The open caisson perpendicularitydetecting and adjusting device is simple in structure; by arranging the infrared transmitting devices, the infrared receiving plates and the jacks on the open caisson wall, it is ensured that infraredrays are transmitted and mapped to the infrared receiving plates, the inclination of the open caisson is adjusted through the jacks, and thus it is ensured that open caisson construction is normallycompleted; the infrared receiving plates are fixed into the open caisson through conical inserting columns on mounting fixing plates, and the infrared transmitting devices are fixed through fixing sleeves and inserted into the open caisson through right fixing plates on the fixing sleeves; and the mounting structure is steady, mounting and demounting are facilitated, the open caisson perpendicularity detecting and adjusting device is simple in structure and is utilized repeatedly, and thus the cost is saved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a caisson verticality detection and adjustment device. Background technique [0002] Before caisson construction, the description of caisson construction method should be compiled according to geological data. Select the sinking method, calculate the sinking coefficient of the caisson at each time, and then determine the construction plan such as fabrication and sinking. The whole process of caisson construction should be observed on time. When sinking, observe at least twice per shift to grasp and correct the displacement and inclination of the caisson in time. The allowable error after the sinking of the caisson should meet the following rules: the difference between the average height of the blade foot and the description height should not exceed 100 mm; The difference in height of the bottom surface of the edge of any two corners of the caisson shall not exceed 0...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing verticality detection devices are often not very accurate and inconvenient to use;

[0004] 2. The existing verticality detection device is fixed in the caisson and is not stable, it is easy to loosen and fall off, and it is inconvenient to detect and adjust the verticality
