Abstract
The utility model relates to the technical field of drainage structures and discloses a drainage structure of a gravity type retaining wall. The drainage structure of the retaining wall comprises a retaining wall with filling soils behind the wall. Drainage holes are formed inside the retaining wall, the water outlets of the drainage holes are arranged on the air-approaching side of the retaining wall, the water inlets of the drainage holes are arranged behind the retaining wall. Blind ditches used for underground water to permeate are buried in the filling soils behind the retaining wall, and the blind ditches are arranged at the water inlets of the drainage holes. Compared with the prior art, the blind ditches are buried behind the retaining wall, and are arranged at the water inlets of the drainage holes. Underground water in soil bodies can converge at the water inlets of the drainage holes, and therefore the underground water is discharged through the drainage holes or can be discharged through two ends of the blind ditches. Due to the blind ditches, the drainage holes can be ensured not to be blocked, and water can be ensured to be discharged smoothly, and therefore the underground water in the soil bodies can be discharged smoothly, and the phenomenon of the inclining or the breaking of the retaining wall caused by pressure of the underground water can be avoided, and life and property security is ensured.
Description
Technical field
The utility model relates to the technical field of discharge structure, relates in particular to the gravity retaining wall discharge structure.
Background technology
Gravity retaining wall is a kind of slope supporting structure commonly used, fill backfill behind the wall, in order to drain the underground water in the soil body behind the wall, be provided with the multilayer spilled water hole in the retaining wall, by the water guiding action of spilled water hole, can be with the ground water discharge in the soil body behind the wall to wall.
In the prior art, stop up for preventing spilled water hole, be provided with the anti-filter capsule in each spilled water hole import department, the anti-filter capsule is comprised of dank material (such as cobble, gravelly sand etc.).Because anti-filter utricule amount is little, to be inconvenient to construct, construction quality is difficult to guarantee.Construction quality from existing retaining wall, spilled water hole in the retaining wall is often stopped up by the soil body, so that spilled water hole impeded drainage, even not draining, like this, long-time after, the ground water discharge of the inboard soil body of retaining wall is not fallen, increase the Water And Earth Pressures that retaining wall bears, easily caused the phenomenons such as retaining wall inclination, cracking, the threat to life property safety.
The utility model content
The utility model provides the discharge structure of gravity retaining wall, is intended to solve easily blocked so that impeded drainage or the not draining of spilled water hole of retaining wall of the prior art, and then causes the problem of the phenomenons such as retaining wall inclination, cracking.
The utility model is to realize like this, the gravity retaining wall discharge structure, comprise the retaining wall that fills backfill behind the wall, be provided with spilled water hole in the described retaining wall, what the delivery port of described spilled water hole placed described retaining wall faces the sky side, after water inlet places described retaining walls, is embedded with the french drain for groundwater seepage after the described retaining walls in the fill stratum, described french drain places the water inlet of described spilled water hole, and communicates with described spilled water hole.
Further, described french drain comprises permeable geosynthetics plastics blind pipe, is coated on the outer macadam of described geosynthetics plastics blind pipe and is coated on the outer geotextile of described macadam.
Further, described french drain is strip, extends along described retaining wall longitudinal direction and arranges.
Compared with prior art, be embedded with french drain after the retaining walls, french drain is positioned at the water inlet of spilled water hole, underground water in the soil body can be pooled to by this french drain the water inlet of spilled water hole, and then excrete out by spilled water hole, also can excrete out from the two ends of french drain, because the effect of french drain, can guarantee that spilled water hole can be not blocked, guarantee that its draining is smooth and easy, thereby can smoothly the ground water discharge in the soil body be gone out, avoid guaranteeing the security of the lives and property because the pressure of underground water causes retaining wall to tilt or the phenomenon of cracking.
Description of drawings
Fig. 1 is the cut-away illustration of the utility model gravity retaining wall discharge structure.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model provides the gravity retaining wall discharge structure, comprise the retaining wall that fills backfill behind the wall, be provided with spilled water hole in the described retaining wall, what the delivery port of described spilled water hole placed described retaining wall faces the sky side, after water inlet places described retaining walls, be embedded with the french drain for groundwater seepage after the described retaining walls in the fill stratum, described french drain places the water inlet of described spilled water hole, and communicates with described spilled water hole.
Utilize the french drain in the utility model, underground water in the soil body can be pooled to the water inlet of spilled water hole, and then outside draining extremely by spilled water hole, also can excrete out from the two ends of french drain, and guarantee that spilled water hole can be not blocked, guarantee that retaining wall can not tilt owing to the pressure of underground water, cracking, guarantee the security of the lives and property.
Below in conjunction with concrete accompanying drawing realization of the present utility model is described in detail.
As shown in Figure 1, a preferred embodiment that provides for the utility model.
The discharge structure 1 that the present embodiment provides is arranged in the retaining wall 2, has filled backfill behind the wall of retaining wall 2, and compiling in the soil body has underground water, and the discharge structure 1 in the present embodiment is used for the ground water discharge of the soil body behind retaining wall 2 walls is gone out outside the retaining wall 2.
Above-mentioned discharge structure 1 comprises and is arranged on spilled water hole 11 in the retaining wall 2, what the delivery port of this spilled water hole 11 placed retaining wall 2 faces the sky side, after its water inlet places retaining wall 2 walls, in order the underground water in the soil body behind retaining wall 2 walls to be collected to the water inlet of spilled water hole 11, and avoid spilled water hole 11 is resulted in blockage, in the present embodiment, the water inlet of spilled water hole 11 is provided with french drain 12, this french drain 12 is arranged on behind the wall of retaining wall 2 in the backfill, it can supply groundwater seepage, like this, underground water behind retaining wall 2 walls in the soil body can be penetrated into by french drain 12 water inlet of spilled water hole 11, and excretes from the delivery port of spilled water hole 11, also can excrete out from the two ends of french drain, because french drain 12 is arranged on the water inlet of spilled water hole 11, it can avoid spilled water hole 11 blocked, thereby guarantees that spilled water hole 11 drainings are smooth and easy, successfully the ground water discharge in the soil body behind retaining wall 2 walls is gone out, avoid guaranteeing the security of the lives and property because the pressure of underground water causes retaining wall 2 to tilt or the phenomenon of cracking.
