Embodiment 1

[0035] Such as Figure 1~6As shown, this embodiment includes a grouting cylinder 1 and a central shaft 2, the two ends of the grouting cylinder 1 are closed, partitions 6 are respectively arranged on the quarter points of the inner circumference of the grouting cylinder 1, and Four partitions 6 divide the interior of the grouting cylinder 1 into two liquid storage chambers and two storage chambers, and the intersection of the four partitions 6 is provided with a shaft hole 5, and the central shaft 2 moves through the shaft hole 5. Extending to the bottom of the pile hole 3, four rows of base pipes 15 are arranged on the outer wall of the grouting cylinder 1 along the circumference thereof, and a plurality of base pipes 5 in each row are arranged in sequence along the axis of the grouting cylinder 1, Two rows of base pipes 15 are respectively connected with the liquid storage chamber, and the remaining two rows of base pipes 15 are connected with the grain storage chamber, and ...

Embodiment 2

[0038] Such as Figure 1~6 As shown, this embodiment is based on Embodiment 1, and the telescopic tube includes a discharge pipe I11, a discharge pipe II13, and a discharge pipe III14 that are sequentially sleeved from the inside to the outside along the radial direction of the base pipe 15, On the outer walls of the discharge pipe I11, the discharge pipe II13 and the discharge pipe III14, there are two locking holes 12 communicating with them, and each locking hole 12 is provided with a locking unit. Both sides of the inner walls of I11, discharge pipe II13 and discharge pipe III14 are provided with limited holes 17, and the outer walls of discharge pipe II13 and discharge pipe III14 are provided with centering holes 35 communicating with them. The base pipe 15 is provided with a waterproof casing on the outer peripheral wall near one end of the grouting cylinder 1, the motor 22 is fixed in the waterproof casing, and the inner wall of the base pipe 15 is provided with an inne...

Embodiment 3

[0045] Such as Figure 1~6 As shown, the present embodiment is based on Embodiment 1. The locking unit includes a locking pin 30, a circular ring 31 and a return spring 32. The circular ring 31 is fixed in the middle of the inner peripheral wall of the locking hole 12, and the return spring The upper end of 32 is connected with the lower surface of ring 31, and the lower end of back-moving spring 32 is connected with the lower section outer peripheral wall of locking pin 30; The upper surface is flush; an annular flange 33 is also provided on the outer peripheral wall of the lower end of the locking pin 30 , and the outer diameter of the flange 33 is smaller than the inner diameter of the locking hole 12 .

[0046] The locking unit in the locking hole 12 is used to connect two adjacent discharge pipes. In the initial state of the technical solution, as the locking pin 30 in the locking hole 12 on the discharge pipe II13 is pressed by the inner wall of the discharge pipe III14 ...

Abstract

The invention discloses a particle excitation type microorganism soil fixation protection wall device. The device comprises a grouting cylinder and a central shaft; four partition plates divide the interior of the grouting cylinder into two liquid storage chambers and two particle storage chambers, four columns of base pipes are arranged on the outer wall of the grouting cylinder, wherein the twocolumn of base pipes communicate with the liquid storage chambers respectively, the remaining two columns of base pipes communicate with the particle storage chambers, a plurality of baffles are arranged on the inner wall of each particle storage chamber, a side plate is arranged on the end part of each baffle, the horizontal lengths of a plurality of solidified particle grooves are sequentially increased from top to bottom, and a stretchable pipe is arranged inside each base pipe. According to the device, the naturally occurring bacillus pasteurii in the soil layer can be excited in situ, thebacillus pasteurii can be advantageously grown by utilizing a specific culture solution, so that the environmental pollution problem caused by the introduction of microorganisms from the outside is effectively avoided, meanwhile, the soil fixation range of the microorganisms can be effectively improved, and the problem that the cured product at the early stage of a grouting port impedes the migration and diffusion of subsequent solutions is solved fundamentally.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction in land reclamation areas, in particular to a particle-inspired microbial soil fixation and wall protection device. Background technique [0002] With the rapid development of the national economy, infrastructure construction has advanced by leaps and bounds, available land resources have become increasingly scarce, and coupled with the in-depth implementation of major strategic deployments of maritime powers, large-scale island and reef construction projects have sprung up like mushrooms after rain. Since dredger fill is a special medium with a large void ratio, high compressibility, and low bearing capacity, it will inevitably encounter a series of geotechnical engineering problems when reclamation and construction of engineering facilities, especially the necking of cast-in-place piles. Engineering accidents such as hole collapse and pile deflection are the most prominent, ...
