The original appearance of the mountain is necessarily damaged in mountain construction projects, and the original mountain surface water drainage system is changed accordingly. At present, the commonly adopted mountain surface water discharge mode is to collect and discharge mountain surface water (mountain rainwater, mountain spring water and the like) in an unorganized way to rural drainage facilities such as nearby flood discharging ditches, farmland irrigation ditches and the like through gaps of a mountain. However, this method cannot avoid the mountain surface water from flowing into the foundation pit, resulting in the foundation construction being affected.
The embodiment of the invention provides a drainage system for draining mountain surface water, which can effectively stop the surface water from flowing into a foundation pit so as to avoid or reduce the adverse effect of the mountain surface water on the foundation construction. A drainage system for draining mountain surface water according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, a drainage system for draining mountain surface water according to an embodiment of the present invention includes a water collecting pipe 1, a mat layer 2, and a barrier layer. The upper wall part of the water collecting pipe 1 forms a water inlet through hole, and surface water can enter the water collecting pipe 1 through the water inlet through hole to be collected and move along the direction of the water discharging end of the water collecting pipe 1. Simultaneously, the inlet opening can obstruct solid particles to enter the interior of the water collecting pipe 1 so as to prevent the solid particles from blocking the interior of the water collecting pipe 1 and influencing the flow of surface water in the pipe.
Referring to fig. 2 and 3, the outer circumferential wall of the water collecting pipe 1 is formed with an outward protruding spiral outer rib 3, the outer rib 3 forms an inclination angle with the outer circumferential wall of the water collecting pipe 1, the inclination angle can be 30 degrees, 45 degrees and the like, on one hand, the outer rib 3 can improve the mechanical strength of the water collecting pipe 1, on the other hand, when the ground water flow is large, the outer rib 3 can make the ground water flowing through the two action surfaces 4 of the outer rib 3 generate a component speed towards the water discharging end of the water collecting pipe 1, so that the water entering the water collecting pipe 1 is promoted to flow towards the water discharging end of the water collecting pipe 1, the flowing speed of the ground water in the water collecting pipe 1 is accelerated, and the blocking amount of the ground water is improved.
The cushion layer 2 is used for supporting the water collecting pipe 1 and the blocking layer, preventing sinking, preventing surface water from continuously permeating downwards and fixing the water collecting pipe 1. Returning now to fig. 1, the cushion layer 2 forms a groove matched with the lower wall part of the water collecting pipe 1, the cushion layer 2 can be formed by pouring cement mortar, before the cement mortar is hardened, the water collecting pipe 1 is arranged on the cement mortar and is provided with corresponding supports, and after the cement mortar is hardened, the cushion layer 2 forms a groove matched with the lower wall part of the water collecting pipe 1. Since the outer circumferential wall of the water collecting pipe 1 forms the spiral outer rib 3, the water collecting pipe 1 and the cushion layer 2 can be tightly fixed.
The barrier layer is laid on the outer side of the upper wall part of the water collecting pipe 1 and used for reducing solid particles which permeate to the outer peripheral wall of the water collecting pipe 1 along with surface water. Surface water filters the back through the barrier layer, and inside through the through-hole of intaking got into collector pipe 1 to the drainage end towards collector pipe 1 flows, thereby, to the supporting facility or the project of selecting to carry out the construction on the massif, at foundation ditch relevant position, set up like the side of intaking of foundation ditch the drainage system for drainage massif surface water can effectively block surface water and gush into the foundation ditch, causes adverse effect to basic construction in order to avoid or reduce massif surface water.
In one embodiment, the barrier layers comprise a first sub-barrier layer 5, a second sub-barrier layer 6, and a third sub-barrier layer 7, which are laid in this order outside the upper wall portion of the water collecting pipe 1. The first sub-barrier 5 is filled with pebbles, the particle size of which gradually increases from a position close to the upper wall portion of the header 1 to a position far from the upper wall portion of the header 1. The second sub-barrier 6 is filled with slate or sand, and the particle size of the second sub-barrier gradually increases from a position close to the upper wall part of the water collecting pipe 1 to a position far away from the upper wall part of the water collecting pipe 1. The third sub-barrier layer 7 is filled with plain soil.
Non-woven fabrics 8 can lay between first sub-barrier layer 5 and the second sub-barrier layer 6, non-woven fabrics 8 can lay between second sub-barrier layer 6 and the third sub-barrier layer 7. The non-woven fabric 8 can separate the sub-barrier layers and block solid particles. The geotextile has excellent filtering, draining, isolating, reinforcing and protecting functions, and has the characteristics of light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance, so that the geotextile can be used for replacing the non-woven fabric 8.
In one embodiment, the drainage system further comprises a water collection well (not shown) connected to the drainage end of the water collection pipe 1 for collecting and storing surface water. Surface water stored in the water collecting well can be used as construction water so as to reasonably utilize water resources around projects.
