Reinforcement meter for measuring support axial force of foundation pit

Abstract

The invention relates to a reinforcement meter for measuring a support axial force of a foundation pit, wherein the reinforcement meter is applied to the field of measurement of a support axial force of a deep foundation pit. The reinforcement meter is composed of a string wire, a coil, string wire fixation clamp bases, a cable, a temperature sensor, a main reinforcement meter body, and a reinforcement meter connecting element. The string wire and the string wire fixation clamp bases are fixed together; and the two string wire fixation clamp bases fix the two ends of the string wire respectively and are fixed on the main reinforcement meter body in a thread manner. The main reinforcement meter body fixes the center of the string wire; and the coil is fixed on the string wire. The temperature sensor is installed inside the main reinforcement meter body and is used for monitoring the temperature of the reinforcement meter; and the coil and the temperature sensor are connected outside the main reinforcement meter body by the cable. Therefore, a problem of unbalance loading of the axial force meter during the steel support axial force monitoring can be solved. With the reinforcement meter, installation becomes simple, data can be observed conveniently, and the stability is high. The reinforcement meter is suitable for steel support axial force monitoring.

Description

technical field [0001] The invention relates to a steel bar meter for measuring the supporting axial force of a foundation pit, which is applied in the field of measuring the supporting axial force of a deep foundation pit. Background technique [0002] With the development of urban construction, urban space resources are becoming more and more expensive, and many projects save urban space resources by going deep underground. Subway projects usually adopt the method of open-cut foundation pit construction. [0003] The internal support type foundation pit enclosure structure has the advantages of simple structure, clear force, strong construction operability, fast progress, and recyclable steel support system, etc., and has been widely used. Most subway stations are located in complex geological conditions and high-risk surrounding environments, and it is often necessary to strictly control the stability and deformation of foundation pits during construction. This goal can...
