Problems solved by technology

However, the thick sediment at the bottom of the hole is a common problem of cast-in-situ piles (walls), which greatly affects the bearing capacity and vertical settlement of cast-in-place piles (walls).
At present, the hole cleaning process is mainly slag removal cylinder, gas lift reverse circulation, etc. These hole cleaning methods are often cumbersome to operate and have poor hole cleaning effect

Embodiment Construction

[0016] figure 1 The overall structure of the present invention is shown. like figure 1 As shown, a slag extraction device used for clearing holes in underground piles and walls includes a cylinder body 1. There is an inverted chamber in the cylinder body 1 that closely fits with the inner side wall of the cylinder body 1 and can move up and down along the inner side wall of the cylinder body 1. A funnel-shaped slag-absorbing tray 2, with a slag-absorbing port 21 in the middle of the slag-absorbing disc 2, and the slag-absorbing port 21 is fixedly connected to the T-shaped connecting pipe 3; a high-speed fluid port 31 is connected to the left side of the T-shaped connecting pipe 3 , the high-speed fluid inlet pipe 31 protrudes outside the top end cover of the cylinder 1, and the slag outlet 34 is on the right side of the T-shaped connecting pipe 3, and the high-speed fluid directly passes through the high-speed fluid pipe 31 outside and enters the T-shaped connecting pipe 3. ...

Abstract

The invention relates to a slag pumping device for an underground pile and a wall cleaning hole. The slag pumping device comprises a barrel, and the barrel is internally provided with a slag suction plate which is matched with the inside wall of the barrel and can be moved up and down; the part, above the slag suction plate, in the barrel is provided with a T type communicating pipe, and the middle part of the slag suction plate is provided with a slag suction inlet communicating with the bottom end of the T type communicating pipe; and one end of the T type communicating pipe is connected toa high-speed fluid pipe, and the other end of the T type communicating pipe is provided with a slag outlet. Sediments are sucked into the barrel only, and the lifting height is small; and the requiredslag removal power is low. Slurry is circulated in a hole, and the stability of the liquid level can be ensured effectively; and the slurry disturbance in the hole can be reduced, and hole collapse is avoided effectively.

Description

technical field [0001] The invention relates to the field of underground space construction, in particular to a slag extraction device for clearing holes in underground piles and walls. Background technique [0002] The development of urban buildings in a higher and deeper direction has put forward great requirements for the bearing capacity and vertical settlement of engineering piles and retaining structure piles (walls). widely. However, a large thickness of sediment at the bottom of the hole is a common problem of cast-in-situ piles (walls), which greatly affects the bearing capacity and vertical settlement of cast-in-place piles (walls). The hole cleaning technology at the present stage is mainly slag removal cylinder, gas lift reverse circulation and other methods. These hole cleaning methods are often cumbersome to operate and have poor hole cleaning effects. Contents of the invention [0003] In order to solve the above problems, the present invention provides a ...
