Abstract
The utility model relates to an underground water guiding and draining structure of an anchoring groove position of a landfill site, aiming at providing an underground water guiding and draining structure of an anchoring groove position of a landfill site, which is simple and practical, has convenient construction, saves investment, can eliminate the underground water or surface phreatic water converged at the upper-edge slope side of the anchoring groove, and prevent an impervious material layer from being damaged. The technical scheme for solving the problems is as follows: the underground water guiding and draining structure of the anchoring groove position of the landfill site is provided with an upper-edge slope side platform, a lower-edge slope side platform and an anchoring groove, which are excavated on the edge slope and distributed with HDPE impervious layers on the surfaces. The underground water guiding and draining structure is characterized in that the upper-edge slope side platform and the groove walls and the groove bottom of the upper-edge slope side of the anchoring groove are laid on a three-dimensional composite water-draining network below the HDPE impervious layers; and the groove bottom of the anchoring groove, close to the lower-edge slope side, is provided with a water-draining pipe communicated with the three-dimensional composite water-draining network. The underground water guiding and draining structure is mainly applicable to anchoring grooves of various valley-type landfill sites, especially valley-type landfill sites with higher edge slopes and more rainwater infiltration at the edge slope.
Description
Technical field
The utility model relates to a kind of landfill yard anchoring ditch position underground water guide structure, mainly is applicable to various mountain valley-type landfill yard anchoring ditches, is specially adapted to the valley type landfill that side slope is higher, the side slope rainwater infiltration is more.
Background technology
Present mountain valley-type landfill yard construction generally is provided with underground water guide system in bottom, landfill yard reservoir area, the reservoir area side slope is not provided with underground water guide system, according to " household garbage sanitary landfills seepage control system engineering " (CJJ113-2007) and " household garbage Sanitary Landfill Technology standard " (CJJ17-2004) etc. standard also only bottom, landfill reservoir area is required to be provided with underground water guide system.But the valley type landfill side slope is generally higher, face of land rock-soil layer transmission coefficient is bigger, the back rainwater infiltration amount of raining is more, because anchoring ditch platform utilizes the massif slope excavation to form, the platform overall width is greater than 3m, and changing appears in the gradient, often cause massif side slope top layer diving from the position exposure of anchoring ditch upside side slope, darker because of anchoring ditch platform excavation, the country rock type is better, and transmission coefficient is little, cause side slope crop out diving to converge at anchoring ditch place, extruding anchoring ditch place impervious material layer, the situation that often causes the impervious material layer to be pulled out or to destroy in anchored end, as shown in Figure 1.
Summary of the invention
The technical problems to be solved in the utility model is: the landfill yard anchoring ditch position underground water guide structure that a kind of simple and practical, easy construction, reduced investment are provided at the problem of above-mentioned existence, can get rid of the side slope side is compiled on the anchoring ditch underground water or face of land diving fast, prevent that the impervious material layer is destroyed.
The technical scheme that the utility model adopted is: landfill yard anchoring ditch position underground water guide structure, have excavation and surface arrangement on the side slope have the HDPE impervious barrier on side slope side platform, down side slope side platform and anchoring ditch, it is characterized in that: the described side slope lateral sulcus wall and bottom of trench gone up on side slope side platform, the anchoring ditch laid the three-dimensional composite drainage network that is positioned at HDPE impervious barrier below, the gutter that anchoring ditch bottom of trench is communicated with three-dimensional composite drainage network by side slope side setting down.
The thickness of described three-dimensional composite drainage network is 6mm.
Described gutter is the pvc pipe of diameter 50mm, and its two ends are fixed by cement mortar.
The beneficial effects of the utility model are: side slope lateral sulcus wall and bottom of trench are laid three-dimensional composite drainage network on the on top sloping side platform of the utility model, the anchoring ditch, thereby will go up the underground water that side slope side platform gathers fast and effectively and be collected to the anchoring bottom of trench by three-dimensional composite drainage network, and the gutter by three-dimensional composite drainage network end enters under anchoring ditch ground water drainage system of subordinate or the landfill reservoir area bottomland and discharges after the water guide system, the phenomenon that the impervious material layer that has effectively prevented to cause because of impeded drainage is pulled out or destroys in anchoring ditch position.
Description of drawings
Fig. 1 is the sectional drawing of the utility model background technology.
Fig. 2 is a sectional drawing of the present utility model.
The specific embodiment
As shown in Figure 2, present embodiment has on the valley type landfill side slope and excavates, and surface arrangement has the last side slope side platform 1 of HDPE impervious barrier 4, following side slope side platform 2 and anchoring ditch 3, be characterized in the described side slope side platform 1 of going up, side slope lateral sulcus wall and bottom of trench are laid the three-dimensional composite drainage network 5 that is positioned at HDPE impervious barrier 4 belows on the anchoring ditch 3, the thickness of three-dimensional composite drainage network 5 is 6mm in this example, the gutter 6 that anchoring ditch 3 bottoms of trench are communicated with three-dimensional composite drainage network 5 by following side slope side setting, gutter 6 adopts the pvc pipe of diameter 50mm to make. fixed a drainpipe 6 o'clock, at the bottom of 3 times side slope lateral sulcus of anchoring ditch, use the hole of rock drilling machine drill Φ 60mm, (pipe distance basis water percolating capacity is down determined to fill in Φ 50mmPVC pipe, generally can consider) by 20m, its two ends get final product by cement mortar is fixing. and go up side slope side platform 1 and compile underground water or the face of land and dive under water and can be directly enter gutter 6 and enter under anchoring ditch underground water guide system of subordinate or the landfill reservoir area bottomland and discharge after the water guide system by three-dimensional composite drainage network 5, under the prerequisite that guarantees anchoring ditch function of use and effect, get rid of fast the underground water or the face of land diving that compile at anchoring ditch place, thus the destruction that the underground water of having avoided gathering causes the anchoring ditch HDPE of place impervious barrier 4.
Described anchoring ditch 3 and last side slope side platform 1, following side slope side platform 2 junction arc transition are punctured by too sharp-pointed corner angle to prevent HDPE impervious barrier 4 and three-dimensional composite drainage network 5.
Claims (3)
