Description
Technical Field
The utility model belongs to the technical field of reinforced structure is administered to the landslide, specifically be a drainage reinforced structure for landslide is administered.
Background
When the mountain height and the steep slope at the rear edge of the slope are controlled, the surface catchment is rapid, the rainstorm is frequently generated in the area where the slope is located, and the slope is mainly in soil landslide consisting of clay, silty clay or gravelly soil, and the like, the intercepting ditches are arranged on the slope to intercept the surface water body flowing along the slope, and the water is drained through two ends of the intercepting ditches, so that the subsurface infiltration of the surface water body and the scouring of the slope are reduced; meanwhile, the drainage side ditch is arranged at the toe of the side slope to collect and drain water on the side slope, so that the phenomenon that the stability of the side slope is greatly reduced due to the fact that the water is washed for a long time and seeps into the slope is avoided. In view of the sudden increase of rainfall during rainstorm, clay, silty clay or gravel soil easily cause the heavy increase of the slope soil body and the reduction of physical and mechanical parameters under the actions of rainfall infiltration and surface layer scouring, thereby inducing the formation of landslide. After the landslide deformation body is formed preliminarily, how to improve the overall stability of the side slope through a simple, effective, economic and reliable side slope drainage scheme is difficult to realize rapid reinforcement of the side slope in landslide control.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a drainage reinforced structure that is used for trailing edge mountain height steep, rainstorm condition surface catchment rush, and the slope body is mainly by the soil property landslide of constituteing such as clay, silty clay or rubble soil to realize the economy and the quick improvement to the landslide.
In order to achieve the above object, the utility model discloses a basic scheme provides a drainage reinforced structure for landslide is administered, include along the domatic incline direction of landslide body and set gradually catch basin and gutter, the length direction of catch basin extends along the landslide body vertical section direction, and the catch basin is provided with a plurality of, and the gutter is located the toe department of the landslide body, be provided with a plurality of drop wells in the catch basin, the intercommunication has the drain pipe between drop well's bottom and the gutter, makes the water on the domatic landslide body collect the gutter after catch basin, drop well and drain pipe in proper order.
The principle and the beneficial effect of the basic scheme are as follows:
1. rainwater collected from the rear edge of the slope body of the side slope flows into the intercepting ditch, is collected into the drop well along the intercepting ditch, and is discharged into the drainage side ditch of the slope toe through the drop well and the drainage pipe at the bottom, so that the side slope is prevented from being unstable due to strong scouring and soil body weakening caused by the fact that the rainwater collected from the rear edge of the side slope flows along the surface of the side slope and infiltrates downwards to the side slope.
2. Through setting up drop well and drain pipe, increased the outlet of catch basin, avoided the catch basin to lead to the drainage untimely because of drainage path is long, the drainage slope is less to lead to the rainwater to spill over and cause the condition emergence of erodeing and weakening to the slope body, and then improved the drainage ability and the overall stability of side slope.
3.

Furthermore, the drain pipe is fixed in an embedding mode. The drain pipe is fixed by adopting an embedding mode and utilizing the extrusion of the surrounding soil body, a structure for supporting the drain pipe is not required to be arranged independently, and the fixing difficulty of the drain pipe is reduced; meanwhile, the drain pipe is buried, so that the phenomenon that the drain pipe is accelerated to age due to long-time solar irradiation can be avoided, and the service life of the drain pipe is prolonged; the drain pipe is buried underground, the phenomenon that the drain pipe is damaged by rock soil rolled down on the side slope and exposed on the surface of the side slope can be avoided, the maintenance operation on the drain pipe is reduced, and the later maintenance cost is reduced.
Furthermore, the length direction of the drain pipe is along the cross section direction of the side slope, the water inlet of the drain pipe is positioned at the bottom of the drop well, and the water outlet is positioned on the side wall of the drain side ditch. The flow distance of the water flow is favorably shortened, and the water flow is quickly collected into the drainage side ditch.
Further, the drain pipe is a wave-shaped drain pipe. When the corrugated drain pipe is buried in the soil body, the occlusion between the corrugated drain pipe and the surrounding soil body can be enhanced, so that the soil body forms support for the corrugated pipe wall in the axial direction of the corrugated drain pipe, and the corrugated drain pipe is kept stable along the inclined direction of the slope body; meanwhile, the wave-shaped drain pipe also supports the soil body, so that the soil body is not easy to slide.
Further, the depth of the drop well is 1.5-3 meters. The depth of the drop well is controlled within the range of 1.5-3 meters, so that the drop well can be ensured to collect water in the intercepting ditch, the phenomenon of overflow of the water in the intercepting ditch is avoided, and the drop well cannot be damaged and invalid when the surface layer of a side slope surface soil body slides under the scouring action of rainfall to cause damage to the intercepting ditch, so that the drop well can continue to drain the side slope, and meanwhile, after the intercepting ditch of the side slope is damaged, the intercepting ditch can be repaired according to the position of the drop well, the repairing difficulty is reduced, and the repairing efficiency is improved.
Furthermore, the top of drop well sets firmly the well lid of net piece formula. After the well cover is arranged, the falling rocks on the side slope can be prevented from falling into the drop well to block the drop well, and the cleaning work added after the rocks fall into the drop well can be reduced.
Further, a slag blocking net sheet covering the water inlet of the water drainage pipe is fixedly arranged at the bottom of the water drop well. The slag blocking net piece is arranged, so that the situation that sundries such as stones, branches and leaves, plastics and the like moving along with water flow block the drain pipe can be avoided, and the drainage of the drain pipe is smooth.
Further, the gutter is of a reinforced concrete structure. The reinforced concrete structure is adopted, so that the structural strength of the gutter is higher, and the gutter is not easy to damage.
Furthermore, the side wall of the drainage side ditch close to the slip mass is of a beam structure with the width-height ratio not less than 2: 3. The side wall adopts a beam type structure with the width-height ratio not less than 2: 3, so that the side wall of one side of the drainage side ditch close to the sliding slope body is thickened, the rigidity and integrity of the side wall of the drainage side ditch are increased, the side wall can support the slope body on the upper part of the drainage side ditch in the width direction, and the stability of the slope body is improved.
