Embodiment 1

[0037] like Figure 1-6 As shown, the present invention proposes a grouting structure for a sleeve valve pipe for a deep filling layer, including a grouting pipe and a grouting core pipe. The grouting pipe includes a multi-section grouting connecting pipe 1 and two grouting connecting pipes 1 The outer ring of the connection is provided with a grouting connection sleeve 2, and one end of the bottom of the grouting connection pipe 1 is connected with a plugging head 3;

[0038] A grouting core pipe is installed in the grouting pipe. The grouting core pipe includes a multi-section core pipe connecting pipe 5. A sleeve tightening mechanism 6 is provided at the joint between the two core pipe connecting pipes 5. The bottom of the bottom grouting core pipe is installed at the bottom. There is a grouting flower tube 8, the two ends of the grouting flower tube 8 are provided with a grouting stopper 7, the inner wall of the grouting connecting pipe 1 is symmetrically provided with a g...

Embodiment 2

[0042] like Figure 1-6 As shown in the figure, the present invention proposes a grouting structure for a sleeve valve pipe for a deep filling layer. Compared with the first embodiment, this embodiment also includes a grouting pipe and a grouting core pipe, and the grouting pipe includes a multi-stage grouting The connecting pipe 1, the grouting connection pipe 1 is provided with a grouting outlet, a check valve 4 is installed in the grouting outlet, and the outer ring of the connection between the two grouting connection pipes 1 is provided with a grouting connection sleeve 2 The bottom end of the grouting connecting pipe 1 is connected with a plugging head 3, the outer rings of both ends of the grouting connecting pipe 1 are provided with threaded grooves, the inner ring of the grouting connecting sleeve 2 is provided with connecting threads, and the grouting connecting sleeve The pipe 2 is rotatably connected with the grouting connecting pipe 1, and the plugging head 3 is c...

Embodiment 3

[0047] like Figure 1-7 As shown in the figure, a construction method for the grouting structure of the sleeve valve pipe of the deep filling layer proposed by the present invention, compared with the first embodiment or the second embodiment, this embodiment further includes the following steps:

[0048] S1. Measurement and drilling rig positioning: locate the drilling position according to the measurement results of soil layer data, and locate the drilling through the drilling rig;

[0049] S2. Assemble the sleeve valve pipe: the grouting pipe and the grouting core pipe are assembled according to the pouring depth of the soil layer. The length of the grouting pipe is greater than the drilling depth. The tightening mechanism 6 is sealed and connected, the grouting connection sleeve 2 is close to the gap between the grouting connection pipes 1 and the inner wall of the grouting connection sleeve 2 is coated with grease to prevent the mortar from solidifying and dismantling unc...

Abstract

The invention relates to the technical field of filling layer grouting, in particular to a sleeve valve pipe grouting structure for a deep filling layer and a construction method of the sleeve valve pipe grouting structure. In order to solve the problems that the connection sealing performance of a grouting core pipe of an existing grouting structure used in the deep and thick soil filling layer needs to be improved, and the grouting position of each section is inconvenient to position, the following technical scheme is provided: the grouting structure comprises a grouting pipe and the grouting core pipe, and the grouting pipe comprises a plurality of sections of grouting connecting pipes; a grouting connecting sleeve is arranged on the outer ring of the joint of the two grouting connecting pipes, and one end of the bottom of each grouting connecting pipe is connected with a plugging head. The sleeve valve pipe is novel and compact in structure, the grouting core pipes are tightly connected, the sleeve valve pipe is suitable for high-pressure grouting operation, the situation that grout leaks and seeps cannot occur, the inner wall of the sleeve valve pipe is clean and tidy, continuous construction is facilitated, the grouting position of the grouting pipe is conveniently positioned, the operation time is shortened, application is more efficient and convenient, and the construction efficiency is improved. The grouting structure is mainly applied to the deep fill stratum sleeve valve pipe.

Description

technical field [0001] The invention relates to the technical field of filling layer grouting, in particular to a sleeve valve pipe grouting structure for deep filling layers and a construction method thereof. Background technique [0002] Construction engineering is a method of injecting some solidified slurry into the cracks or pores of the rock foundation by appropriate methods, and improving its physical and mechanical properties through replacement, filling, extrusion, etc.; the construction surface is located on the backfill soil layer. , According to the requirements of the foundation bearing capacity, due to the limited impact depth of dynamic compaction, and the backfill is mostly large pieces of weathered rock, miscellaneous fill, and construction waste, according to the site foundation excavation, the soil at the bottom of the fill layer is relatively loose, so it is deep The backfill soil layer is difficult to form soil consolidation in a short time, and it is ea...
