Measuring device of pouring pile concrete surface

Abstract

The invention discloses a measuring device of pouring pile concrete surface, which comprises a measuring device body, a middle sleeve, a floating board, a guider, a measuring rope, a tension sensor, a battery, and a TD-CLF-L3 type controller. The outer side of the middle sleeve is sleeved with the floating board, a metal rod is arranged inside a first through hole, a lead ball is arranged inside a blind hole, the guider is arranged inside a second through hole, the measuring device body is sheathed in the middle of a guide tube, the tension sensor is arranged on one side of the measuring rope, near the floating board, a motor is arranged on one side of a runner, a telescopic rod is arranged on one side of the top of a base, and the TD-CLF-L3 type controller is arranged on one side of the battery. The device, when used for pouring concrete, moves upwards along with the concrete surface so that the depth of the concrete surface can be accurately known through the measuring rope connected with the device. Even in the event of an upper borehole collapse, the measurement will not be affected and material waste can be effectively controlled. The measuring rope is pulled by the motor, thereby saving manpower.

Description

technical field [0001] The invention relates to the technical field of concrete pouring measurement, in particular to a measuring device for the concrete surface of cast-in-situ piles. Background technique [0002] The traditional concrete surface measurement device is mainly composed of a measuring rope and a short steel bar or a heavy steel product. The advantage of this device is that it is easy to make and the materials are easy to obtain. However, this device completely relies on experience to measure the depth of the concrete surface. , the error is very large, and the depth of the concrete surface cannot be accurately measured. Especially when the concrete surface is deep from the ground when the pouring is stopped, due to the increased mud weight and the instability of the upper borehole wall, the measured concrete top surface is quite different from the actual concrete surface. In order to ensure that the pile top concrete Quality, in actual construction, more conc...

[0002] The traditional concrete surface measurement device is mainly composed of a measuring rope and a short steel bar or a heavy steel product. The advantage of this device is that it is easy to make and the materials are easy to obtain. However, this device completely relies on experience to measure the depth of the concrete surface. , the error is large, and the depth of the concrete surface cannot be accurately measured

Especially when the concrete surface is deep from the ground when the pouring is stopped, due to the increased mud weight and the instability of the upper borehole wall, the measured concrete top surface is quite different from the actual concrete surface. In order to ensure that the pile top concrete Quality, in actual construction, more concrete is often poured, the construction time is longer, and a large amount of unnecessary construction cost increase or waste is caused
