Embodiment 1

[0036] This embodiment provides an ultra-high pressure angle domain variable speed jet grouting method, such as figure 2 As shown, it is characterized in that, comprising the following steps:

[0037] Step 1, area selection step: determine the consolidation area, and the width change value of the consolidation area is less than a set threshold. The consolidation area is selected according to the area to be constructed to obtain the curtain wall. Specifically, the thickness can be selected according to the requirements of the curtain wall. The curtain wall can be regarded as an approximate cuboid structure, which has length, width and height. According to the solid The depth of the knot region can determine the height of the curtain wall, the width of the consolidation region can determine the width of the curtain wall, and the length of the consolidation region can determine the length of the curtain wall. For the curtain wall, its width needs to meet the anti-seepage requir...

Embodiment 2

[0042] The ultra-high pressure angle domain variable speed jet grouting method provided in this example has the following improvements on the basis of the solution described in Example 1:

[0043] In the region selection step of step one, refer to image 3 , the consolidation region is a plurality of continuous elliptical cylinder 301 structures, wherein two adjacent elliptical cylinders 301 are partially overlapped; Adjacent elliptical columns 301 are divided into a grouting section. Preferably, as shown in the figure, two adjacent elliptical cylinders 301 overlap in the following manner: the first side focus of one of the elliptical cylinders coincides with the second side focus of the other elliptical cylinder. image 3 The middle coincident point 302 is located on the right focus of the left elliptical cylinder and the left focus of the right elliptical cylinder at the same time. In the above solution, the structures of different elliptical cylinders may be the same or d...

Embodiment 3

[0065] This embodiment provides a curtain wall constructed by using the ultra-high pressure angle-domain variable-speed jet grouting method in the above-mentioned embodiment. Refer to Figure 5 , the curtain wall 5 obtained by using the grouting method in the embodiment of the present invention. Will Figure 5 The curtain wall shown with Figure 1-a , 1-b Compared with the curtain wall in 1-c, it can be seen that the wall thickness of the curtain wall obtained in the embodiment of the present invention at the location of the grouting pipe is less different from the thickness of the surrounding walls, and the thickness of the wall is basically uniform, and Material is saved to the greatest extent.

Abstract

The invention provides an ultra-high-pressure angular domain variable-speed flow-jet grouting method and a curtain wall. The ultra-high-pressure angular domain variable-speed flow-jet grouting methodcomprises the steps that a solidification area is determined, and the width variation value of the solidification area is less than a set threshold value; the solidification area is divided into N grouting sections in the length direction, wherein the length of the i grouting section is twice the jet distance of a grouting pipe; grouting operation from low to high is conducted on the solidification area; when the i grouting section is grouted, the grouting pipe is arranged at the central axis of the i grouting section for lifting while rotary spouting, the rotating speed of the grouting pipe is controlled according to the distance between a mortar outlet of the grouting pipe and the edge of the i grouting section, and the greater the distance between the mortar outlet and the edge is, the lower the rotating speed of the grouting pipe is. By adopting the ultra-high-pressure angular domain variable-speed flow-jet method, the problem of waste of rotary jet materials is solved, and it can be further ensured that the thickness of a wall body is basically uniform.

Description

technical field [0001] The invention is mainly applied in the technical field of water conservancy infrastructure engineering facilities, and in particular relates to an ultra-high pressure angle domain variable speed jet grouting method and a curtain wall.
