Abstract
The utility model relates to a compound impervious wall, which comprises mutually connected high-pressure jet plate shells formed by the high-pressure jet grouting of a high-pressure jet grouting hole and a wall kernel formed by the static pressure grouting of a filling grouting hole, wherein the wall kernel is connected with the high-pressure jet plate shells to construct an integral structure to form the compound impervious wall. In the utility model, a high-pressure jet sprouting technology and a static pressure filling grouting technology are combined, and jet sprouting can be repeated for four times at the far end of a jet hole with relatively high defect rate, i.e. at the junction of two grouting hole plate walls, and at the time, the energy of high-pressure water and airflow is used on the lapping of the plate walls without wastes, and thereby, the quality of high-pressure jet wall plates and the junction thereof is ensured; and moreover, the wall kernel further repairs the hole defect of the high-pressure jet wall plates and simultaneously fills the gaps of the contact surfaces of the high-pressure jet wall plates and bed rocks and blocks up the leak paths of the cracks of the bed rocks, and therefore, the compound impervious wall has very high comprehensive imperviousness.
Description
Technical field
The utility model relates to the underground impervious wall structure that adopts high pressure jet grouting machinery swing injection to form, and particularly relates to a kind of compound impervious wall.
Background technology
High pressure jet grouting worker method is widely used in department's building underground impervious walls such as industry, civilian construction, traffic, water conservancy and national defence by boring and pendulum spray building underground impervious wall with its advantage that is suitable for than bad ground.Be to utilize the swing of high pressure jet grouting machine to spray to form pendulum spray board wall in the past, common single high spray impervious wall thickness generally approaches (10-30cm), especially there is cavity property defective in the injection of the height in pebble layer body of wall, high so simultaneously spray wall and basement rock contact surface generally exist infiltration hidden danger, therefore, be difficult to satisfy the higher antiseepage and the life requirement of building.
The utility model content
The technical problems to be solved in the utility model provides a kind of barrier performance height, good endurance, is applicable to antiseepage requirement height, a kind of compound impervious wall of the strong building of durability.
The technical scheme that adopts is:
A kind of compound impervious wall comprises the body of wall kernel that is formed interconnective high spray plate shell and formed by the grouting of filling grout hole static pressure by high pressure jet grouting hole high pressure jet grouting.Described body of wall kernel connects high spray plate shell and is built into an overall structure, forms a kind of compound impervious wall.
The utility model combines High Pressure Jet Grouting Technique with static pressure filling grouting technique, at the higher relatively spray-hole far-end of ratio of defects, i.e. two grout hole board wall junctions, can repeat jet grouting through four times, the energy of water under high pressure, air-flow has no to be used in lavishly on the overlap joint of board wall at this moment, thereby has guaranteed the quality of high spray wallboard and junction thereof.In addition, the body of wall kernel has further been repaired the hole defective of high spray wallboard, filling simultaneously the slit of high spray wallboard and basement rock contact surface and shutoff the leakage passage in basement rock crack, so compound impervious wall has very high comprehensive barrier performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of compound impervious wall comprises that forming angle by double high pressure jet grouting hole 1 high pressure swing sprinkling irrigation slurry is the body of wall kernel 3 that 120 ° fan-shaped board wall docks into the high spray of continuous rhombus well shape plate shell 4 and is in the milk and formed by filling grout hole 2 static pressure.Described body of wall kernel 3 connects high spray plate shell 4 and is built into an overall structure, forms compound impervious wall.This underground impervious wall thickness is 0.5-0.85m, wall enclosure compressive strength R
28=6-7Mpa, kernel pressure degree R
28=5-6Mpa, the average coefficient of permeability K=Ax (10 of body of wall
-8-10
-7Cm/s), can reach 50 years application life.
A kind of compound impervious wall sample project was built up on certain island in 1991, went through nearly 20 years underground sea water and soaked, and showed that impervious wall is superior in quality, the anti-seepage effect ideal.
