Embodiment Construction

[0035] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The present invention proposes an embodiment of a slag removal and grouting device. Refer to figure 1 As shown, it includes an air compressor 1 and / or a high-pressure pump 2, a low-pressure speed-regulating pump 3 and a short grouting pipe 4. The short grouting pipe 4 is provided with a valve 41 that can be opened and closed. The air compressor 1 And / or the high-pressure pump 2 is connected with a high-pressure grouting pipe 5 that can go deep into the bottom of the coring hole, and the low-pressure speed-regulating pump 3 is connected with a low-pressure grouting pipe 6 that can go deep into the bottom of the coring hole.

[0036] The slag removal and grouting device in this embodiment can cooperate with the air compressor 1 and the high-pressure pump 2 during the slag removal, and be connected with the high-pres...

Abstract

The invention provides a sediment removal and grouting device. The sediment removal and grouting device comprises an air compressor and / or a high-pressure pump, a low-pressure speed governing pump and a grouting short pipe, wherein the grouting short pipe is provided with a valve capable of being opened and closed; the air compressor and / or the high-pressure pump are / is connected with a high-pressure grouting pipe capable of going deep into the bottom of a core hole; and the low-pressure speed governing pump is connected with a low-pressure grouting pipe capable of going deep into the bottom of the coring hole. By means of the sediment removal and grouting device, the problems that in the prior art, the cleaning effect for sediment at the bottom of a filling pile is poor, and the filling pile is poor in bearing capacity and high in cost after being reinforced again are solved.

Description

technical field [0001] The invention relates to a slag-cleaning grouting device and a method for slag-cleaning grouting using the device. Background technique [0002] Cast-in-situ pile is the most important pile type in construction projects. Too thick sediment at the bottom of the pile is a major quality problem for mechanically holed cast-in-place piles. Excessive bottom sediment is often discovered during the inspection of cast-in-place piles. How to quickly and economically solve the quality problem of excessively thick bottom sediment after construction has always been a difficult point. [0003] The technical name of the patent is "a construction method for bored cast-in-place piles using gas-lift reverse circulation to clean up sediment" and the application publication number is CN104343114A. Method" application publication number is the invention patent of CN105649559A and the invention patent of the name "cast-in-situ pile hole bottom sediment cleaning device" aut...
