Abstract
The utility model discloses a drainage structure for reducing underground water level and water content of a slope soil. A plurality of drain pipes are fully arranged along the surface of the slope soil and placed as per a rectangular array or a quincunx array; the drain pipes are inserted into the surface of the slope soil horizontally or at the angle of inclination of 0-5 degrees, the outer ends of the drain pipes are exposed out of the surface of the slope soil, a plurality of drain holes are placed in the drain pipes according to the rectangular array or the quincunx array, and dense-mesh gauzes wrap the outer walls of the drain pipes and the end parts of the drain pipes extending into the slope soil. According to the drainage structure, underground water can be timely and effectively drained, the underground water level and the water content and the water migration amount of a slope are reduced, the original swelling soil of the slope can be prevented from being replaced by non-swelling coarse aggregates with large permeability coefficients in a slope project in a cold region, therefore, not only is the stability of the slope guaranteed, but also the construction cost is greatly reduced.
Description
Technical field
The utility model relates to the technology that reduces slope soil groundwater table and moisture content, specifically, relates to a kind of white-out structure that is applicable to different kinds of roads side slope, house foundation side slope, natural slope underground water.
Background technology
Can produce disadvantageous osmotic pressure, flowing pressure, uplift pressure etc. to side slope when the groundwater table height of slope soil and soil moisture content are higher, also can reduce the intensity of slope soil; If also can bring disadvantageous freeze injury to side slope at Han Qu, have a strong impact on the security and stability of side slope.
At present slope project is also without any the groundwater table and the slope soil moisture content that can the measure of taking the initiative reduce side slope, just the retaining structures such as the antislide pile by strengthening the side slope toe and retaining wall strengthen skid resistance, not only greatly increase construction costs and duration, also stayed certain potential safety hazard to slope project.
The utility model content
To be solved in the utility model is to reduce the groundwater table of side slope and the technical problem of slope soil moisture content, and a kind of white-out structure that reduces slope soil groundwater table and moisture content is provided, and can improve the security and stability of side slope, and construction costs is low simultaneously.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of white-out structure that reduces slope soil groundwater table and moisture content, be provided with a plurality of gutters along full slope, slope soil surface, a plurality of described gutters are according to rectangular array or quincunx arranged in arrays, described drain level or surperficial with 0 ~ 5 ° of inclination angle insertion slope soil, the slope soil surface is exposed in described gutter outer end, according to rectangular array or quincunx arranged in arrays a plurality of drain holes are arranged on the described gutter, the end that described gutter outer wall and described gutter stretch in the slope soil is enclosed with close order gauze.
Slope soil surface 10 ~ 30cm is exposed in described gutter outer end.
The level interval that described gutter is arranged on the slope soil surface is 1.5 ~ 2.2m, and vertical spacing is 1.1 ~ 1.5m.
Described gutter is PE gutter, PVC gutter or steel gutter.
The diameter of described drain hole is 5 ~ 8mm.
Described close order gauze is provided with 1 ~ 5 layer.
The order number of described close order gauze is 100 ~ 150 orders.
The beneficial effects of the utility model are:
The utility model adopts the gutter of arranging according to certain level and vertical spacing, and gutter is provided with the drain hole of arranging according to certain rules, underground water that can the white-out slope soil, thus reduce groundwater table and the side slope moisture content of side slope; The gutter outer wall is enclosed with the close order gauze of some layers, can prevent that fine grained soils in the side slope runs off and the increase of slope soil hole and the strength decreased that cause from gutter.
The utility model is white-out underground water timely and effectively, dewatering, side slope moisture content and water translocation amount, in cold district slope project, can also avoid adopting the large non-frost heave coarse aggregate of transmission coefficient all to replace the original swelling soil of side slope, not only guaranteed the stability of side slope, and can the decrease construction costs.

The specific embodiment
For further understanding content of the present utility model, characteristics and effect, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
As depicted in figs. 1 and 2, the utility model discloses the white-out structure that reduces slope soil groundwater table and moisture content, according to slope engineering geological conditions, slope angle, sloping height, domatic area, the gutter 2 of some is set on full slope, slope soil 1 surface, and its quantity is set according to domatic area and cut slope soil body water content.Gutter 2 forms certain level interval and vertical spacing according to rectangular array or quincunx arranged in arrays between the tube and tube, generally in 1.5 ~ 2.2m scope, vertical spacing is generally in 1.1 ~ 1.5m scope for level interval.Gutter 2 level of answering is inserted slope soil 1 surface, and perhaps slope soil 1 surface is inserted with 0 ~ 5 ° of inclination angle downwards in the outer end, and gutter 2 need expose slope soil 1 surface, and the length of exposing is generally 10 ~ 30cm.Gutter 2 can be selected PE gutter, PVC gutter or steel gutter.
As shown in Figure 3, be drilled with the drain hole 3 of several minor diameters on the gutter 2, the diameter of drain hole 3 is determined concrete numerical value according to the slope soil water content, is generally 5 ~ 8mm.Drain hole 3 arranging on gutter 2 also is according to rectangular array or quincunx arranged in arrays.
As shown in Figure 4, the outer wall of gutter 2, and the end that gutter 2 stretches in the slope soil 1 is enclosed with close order gauze 4.Close order gauze 4 is provided with 1 ~ 5 layer, and the order number of close order gauze 4 is take 100 ~ 150 orders as good.
The work progress of white-out structure of the present utility model is as follows:
