Device for testing the verticality of bridge piers

Abstract

The invention discloses a device for detecting the verticality of a pier column of a bridge and belongs to the technical field of bridge detection equipment. The device consists of an infrared distance meter 1, an angle recorder 2, an angle adjusting knob 3, a connecting bracket 4, a round steel supporting seat 5, a telescope holder 6, a level gauge 7, a telescope 8, a tripod connecting supporting seat 9, a data transmission line 10, a data recorder 11 and a telescope adjusting knob 12, wherein according to an assembling relationship, the infrared distance meter 1 is mounted on the angle recorder 2, the angle recorder 2 is mounted at the front end of the connecting bracket 4, the lower end of the connecting bracket 4 is mounted on the right side above the round steel supporting seat 5, the telescope holder 6 which is provided with the telescope 8 is mounted on the left side above the round steel supporting seat 5, the level gauge 7 is mounted at the edge of the right side above the round steel supporting seat 5, the tripod connecting supporting seat 9 is mounted below the round steel supporting seat 5, and the data transmission line 10 is connected with the infrared distance meter 1, the angle recorder 2 and the data recorder 11 respectively. The device is simple in structure and large in detection range, the effects of energy conservation and emission reduction are obvious, and a new field of the verticality detection of the pier column of the bridge is developed.

Description

technical field [0001] The invention relates to a device for detecting the verticality of bridge pier columns, which belongs to the technical field of bridge detection equipment. Background technique [0002] The application field of this technology is mainly aimed at the following three types of bridges: 1. Bridges under construction or bridges to be opened to traffic; For special bridges that have been monitored for a long time, especially some bridges with reduced pile foundation bearing capacity or severe erosion in the river, according to the relevant regulations of the Ministry of Transport, the verticality of the piers must be tested; to ensure that the bridge can be used during the opening to traffic. Safe operation. At present, two methods are usually used to detect the verticality of bridge pier columns. One is that the inspectors use the inspection frame of the bridge quality inspection vehicle to place a drop ball on the top of the pier column for inspection (th...

Problems solved by technology

However, there are still three problems in the above method in the actual detection work: 1. The 2-meter-foot method detects the height of the pier column is limited, and can only detect the verticality of the bridge pier column in the 2-4 meter height range above the ground, but in the actual construction site Many pier columns on the site are more than 4 meters long; 2. The work efficiency of the vertical ball method is low and affected by many external factors. Personnel need to use the bridge inspection frame to carry out the inspection. The inspection is often affected by factors such as external wind, mechanical shaking, and personnel operation. The row effect is poor. When using the vertical ball method to detect the verticality of the pier columns, it is necessary to use bridge inspection vehicles and more than 3 inspection personnel, so the vertical ball method has poor energy-saving and emission reduction effects.

[0003] In order to overcome the shortcomings of the existing detection device for the verticality of bridge piers and columns, the detection height is limited and the detection work efficiency is low, the invention is provided
