Rotary excavating pile sediment thickness measurer

Abstract

The invention discloses a rotary excavating pile sediment thickness measurer. The lower end of a lifting rope is fixed to a lifting lug; the upper end of a measuring ruler is fixed to the center of a bottom surface of a balancing weight, the lower end of the measuring ruler is a tip end, and a top surface of the tip end is a flat surface; a side face of the measuring ruler is provided with measuring scales along a length direction from the lower end to the upper end, each scale value of the measuring scales is 5mm, the bottom of the tip end corresponds to the ''zero'' point of the measuring scales, and the scale value of the upper end of the measuring scales is larger than 50cm; and one end face of the measuring ruler is provided with a set of sawteeth along the length direction which extend from the upper end of the tip end to the upper end of the measuring ruler. The rotary excavating pile sediment thickness measurer provided by the invention can measure the sediment thickness of each position, and can automatically measure a maximum sediment thickness, the measurement accuracy is high, measurement is simple, convenient and rapid, and the measurement efficiency is substantially improved.

Description

technical field [0001] The invention belongs to the field of engineering construction, in particular to a sediment thickness measuring device for rotary excavation piles. Background technique [0002] With the development of building construction technology, the rotary excavation pile construction technology has been vigorously promoted and applied to the foundation pile construction of roads, railways, bridges and large buildings in recent years. As an important indicator of the hole quality inspection of rotary excavation piles, the thickness of the sediment at the bottom of the pile has a huge impact on the construction quality of the pile foundation. The thickness of the sediment at the bottom of the fixed rotary excavation pile in the building code cannot exceed 50 cm, so it is especially important to measure the thickness of the sediment at the bottom of the pile. important. Due to its technical characteristics, safety considerations and the limitations of the hole-fo...

AI Technical Summary

Problems solved by technology

[0005] 1. When measuring the sediment thickness at each position, it is impossible for the disk to fall on the same position, which will lead to inaccurate calculation of the sediment thickness at a single position, and it is impossible to accurately find the sediment thickness at the bottom of the pile;

[0006] 2. Due to the need for multiple measurements, the depth of the rotary excavation pile is basically more than 10 meters, which is time-consuming and laborious, the operation is very inconvenient, and the measurement efficiency is low
