Device for measuring depth of slurry in cast-in-place pile

Abstract

The invention discloses a device for measuring the depth of slurry in a cast-in-place pile, and the device comprises a hollow conical vibrator, a vibration motor, a first telescoping calibrated scale, a second telescoping calibrated scale, a floating disc with holes, and a telescoping traction rope. The vibration motor is disposed in the inner cavity of the conical vibrator, the first telescoping calibrated scale is vertically disposed on the top surface of the conical vibrator, and the second telescoping calibrated scale is disposed on the top surface of the conical vibrator. The floating disc with holes penetrates through the first telescopic graduated scale and ascends and descends along the first telescopic graduated scale, the second telescopic graduated scale is arranged on the top face of the floating disc with holes and is parallel to the first telescopic graduated scale, and the two ends of the telescopic traction rope are connected with the bottom face of the floating disc with holes and the top face of the conical vibrator respectively. The device overcomes the defects of traditional mud depth measurement, the depth of mud is calculated through the density buoyancy of power, water and mud, the device has the advantages of being efficient, scientific and accurate, and construction and hole forming quality of cast-in-place pile drilling are ensured.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a measuring device for the depth of mud in a cast-in-place pile. Background technique [0002] Usually, the drilling of cast-in-place piles is usually carried out by the mud retaining wall construction method. When the concrete is finally poured, there will be a certain amount of mud residue, which will cover the upper layer of the concrete slurry. In the actual construction process, the method of steel brazing is mostly used, and the depth of the mud is measured by the feeling of the workers to determine the final amount of concrete poured. This test method is unreliable. Too much pouring amount will cause material waste, and less pouring amount will cause the quality of the cast-in-place pile to be substandard, which will seriously affect the construction and hole-forming quality of the cast-in-place pile. SUMMARY OF THE INVENTION [0003] The technical problem to be solve...

AI Technical Summary

Problems solved by technology

This test method is unreliable. If the amount of pouring is too large, the material will be wasted. If the amount of pouring is small, the quality of the cast-in-situ pile will not meet the standard, which will seriously affect the construction of the bored pile and the quality of the hole.
