A soil filling stop device for rotary excavation of pile holes

Abstract

The invention relates to the technical field of rotary excavation pile holes, and discloses a soil accumulation stop device for rotary excavation of pile holes, comprising a first stop side plate, a second stop side plate, a support rod and a first stop The top plate, the second stop side plate is located on the right side of the first stop side plate, the left end of the support rod is engaged with the first support seat, and the right end of the support rod is connected with the second support seat The first stop top plate is located on the right side wall of the top plate insert block, and is fixedly connected with the first stop top plate; by arranging the first stop side plate and the second stop side plate, the The soil is placed on the top side of the supporting and expanding pile holes to prevent the soil on the top side from falling off when the pile holes are excavated, so as to ensure the safety of construction. The top of the pile hole is filled with soil to prevent the top of the pile from falling off when the pile hole is rotated, so as to ensure the safety of construction and facilitate the subsequent use of machinery for rotary excavation and expansion of the bottom pile.

Description

technical field [0001] The invention relates to the technical field of rotary digging pile holes, in particular to a soil filling stop device used for rotary digging pile holes. Background technique [0002] In the construction of foundation piles for highways, railways, bridges and large buildings, the construction methods of foundation piles have undergone a process of continuous technological innovation from traditional manual excavation to mechanical rotary excavation pile construction. The traditional pile holes are manually excavated, and the diameter of the bottom of the artificially excavated piles is enlarged, which is called the artificially excavated and expanded bottom piles. Because of their reliable mechanical performance, this type of pile does not require large machinery and equipment, and the construction operation process is simple and can be directly inspected. Due to the rock and soil layer at the bottom of the pile, the single pile has high bearing capac...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a soil accumulation stop device for rotary digging pile holes, which solves the problems of high labor intensity in digging holes, slow construction speed of single piles, and especially poor safety. Dangerous situations such as landslides are prone to occur. When the gas produced by humus in the soil layer escapes into the hole, a large amount of toxic gas will be deposited at the bottom of the pile hole, which brings safety hazards to construction safety.
