Problems solved by technology

This measure is very laborious, laborious and expensive
It cannot be used when there is groundwater, because there is groundwater to replace the soil and the pressure is not firm, and the newly built slope cannot be stable; Block the slope sliding body
The engineering structure and the deformation of the soil are also not suitable. The design of the reinforced concrete anti-slide pile is 1m in diameter, 12-30m in depth, and 1m in thickness and 2.5m in depth. The project investment is large, and ordinary projects cannot bear it

Embodiment Construction

[0016] As shown in Fig. 1 and Fig. 2, grooves are dug on the 1:3 side slopes of channels and dams in expansive soil areas with a 2.5m deep, 4m side length, and 0.2m wide diamond-shaped continuous grid, and each Drill a 5m deep rammed and expanded pile hole at the apex of the rhombus grid, and the diameter of the hole is 0.3m;

[0017] Lay reinforcement cages in the rammed and expanded pile holes, and lay steel mesh in the diamond-shaped frame grooves to make the two steel bars tightly connected, and then pour C20 grade concrete, thus forming a 5m deep rammed and expanded pile rooted in the slope 1 And reinforced concrete continuous rhombus slab 2;

[0018] The expansive soil on the slope surface surrounded by the sash board is filled with water to reach a saturated state to make it expand. At this time, the continuous diamond-shaped frame plate and the expansive soil on the slope form a composite slope protection layer with a certain internal stress. Concrete seals the slope...

Abstract

This invention discloses a new technique for securing landslip with swelled soil. Rhombus continuous sash slots of 2-4 meters depth, 2-10 meters elngth, 0.2-0.5 meter width is dign on side slpe of original swelled clay, ram enlarge pile hole is drilled on each rhombus sash acme. Reinforcement cage and reinforcing mat is set in the slot and then concrete is placed to form reinforced concrete continuous rhombus sash board. slope swelled soil that embraced by sash board is irrigating water, and then slope is sealed by concrete or other impermeable material when swelled soil sopping is on biggest saturation. Reinforced concrete continuous rhombus sash net style complex slope protection is used in this invention, and swelling property of swelled soil is transformed into internal stress of complex slope protection to ensure side slope secular stability. Engineering measures is simple, fabrication cost is lost, and technique economic benefit is good.

Description

technical field [0001] The invention relates to a method for preventing and controlling soil landslides, in particular to a new technology for controlling expansive soil landslides. Background technique [0002] Any civil works such as dikes or channels have slopes. At present, the destruction of such engineering slopes in expansive soil areas can be seen everywhere, which is a very common phenomenon of geological disasters. The study found that due to the special formation conditions of expansive soil, its structure and characteristics are also very special. Exploration tests show that expansive soil is a kind of rock with strong expansion and contraction and water absorption. This kind of soil loses water, dries up, shrinks, cracks, saturates and swells when it encounters water absorption, so that the shear strength of the soil decreases sharply, leading to landslides successively on the dams and channel slopes in the expansive soil area, and in light cases, the channel s...
