Description

Technical Field

[0001] The utility model relates to a slope body drainage structure. Background Art

[0002] The occurrence and migration of groundwater is one of the main natural factors affecting slope stability. The source of groundwater in slopes is mainly groundwater recharge and slope water infiltration. After years of continuous development, slope drainage technology has become relatively mature. Drainage facilities such as cutting top interception ditches, platform drainage ditches, rapids troughs, and waterfalls constitute a complete slope drainage system. However, slope drainage solutions are limited by the complexity of groundwater occurrence and often require targeted special designs.

[0003] At present, most underground drainage schemes for slope projects use upward-inclined drainage holes. The drainage holes are equipped with a filter layer or filter bag on one side of the slope, generally arranged in a plum blossom pattern with a spacing of 2 to 3 meters. In actual engineering, due to the small volume of the filter layer or filter bag and the single-point distribution, the drainage holes have less water inflow and the slope drainage effect is poor. Taking all these factors into consideration, a slope drainage structure with simple structure, efficient drainage, convenient construction and low cost is needed. Utility Model Content

[0004] The utility model aims to solve the problem that the general upward-inclined drainage holes have poor drainage effect and insufficient pertinence during the drainage of the slope body, and provides a slope body drainage structure with simple structure, high drainage efficiency, convenient construction and low cost.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problems is: a slope drainage structure, which is characterized by: comprising a water collecting trough, a water collecting pipe and a drainage pipe; a plurality of water inlet holes are arranged on the upper part of the water collecting trough; a water outlet is arranged at the bottom of the water collecting trough, and a water inlet is arranged on the side; the drainage pipe is installed on the water outlet of the water collecting trough through a flexible pipe joint; the water collecting pipe is installed on the water inlet of the water collecting trough through a flexible pipe joint, and the water collecting pipe is provided with water inlet holes.

[0006] The water collecting grooves described in the utility model are a plurality of water collecting grooves which are arranged in sequence and adjacent water collecting grooves are connected together.

[0007] The adjacent water collecting tanks of the utility model are connected together through connecting sleeve rings.

[0008] The bottom surface of the water collecting tank described in the utility model is V-shaped.

[0009] The water collecting pipes described in the utility model are multiple and arranged in parallel.

[0010] Compared with the prior art, the utility model has the following advantages and effects:

[0011] 1. The utility model combines the advantages of groundwater drainage structures such as blind ditches and water collection wells, greatly increases the water inlet area of ​​the water collection tank, and the drainage effect is more effective;

[0012] 2. The utility model adds a water collecting pipe in the deep stratum, which can discharge more groundwater inside the slope body and improve the drainage efficiency.

[0013] 3. The utility model has a simple overall structure and can be mass-produced. It also adopts an assembled structure and can be assembled according to the specific conditions of the groundwater on the slope, thus greatly improving the drainage efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] FIG1 is a schematic structural diagram of an embodiment of the utility model. DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0016] The embodiment of the utility model comprises a water collecting tank 1, a connecting ring 4, a water collecting pipe 6 and a drainage pipe 3.

[0017] The water collecting tank 1 is composed of several pieces, which are arranged in sequence. Adjacent water collecting tanks 1 are connected by connecting collars 4, which can be used in multiple groups for extension. The connecting collars 4 are fixed with mounting bolts 5 to the connecting collars 4 and the water collecting tank 1. A plurality of water inlet holes are arranged on the upper part of the water collecting tank 1 to increase the drainage area of ​​the groundwater in the upper stratum. The bottom of the water collecting tank 1 is provided with a water outlet, and the side is provided with a water inlet. The bottom surface of the water collecting tank 1 is V-shaped, which is convenient for draining groundwater to the water outlet and preventing water accumulation in the water collecting tank 1.

[0018] The drainage pipe 3 is installed on the water outlet of the water collecting tank 1 through the flexible pipe joint 2. The water collecting pipe 6 is installed on the water inlet of the water collecting tank 1 through the flexible pipe joint 2. There are multiple water collecting pipes 6, which are arranged side by side. One or more rows of water collecting pipes 6 are selected according to the water-rich situation of the formation; multiple water inlet holes are arranged on the water collecting pipe 6. Since the flexible pipe joint 2 can be freely extended and rotated, the angle of the water collecting pipe 6 and the drainage pipe 3 can be adjusted at will.

[0019] When in use, the water collecting pipe 6 is wrapped with geotextile and inserted into the pre-drilled water collecting hole, which can lead more groundwater into the water collecting tank 1. The outside of the water collecting tank 1 should be wrapped with a layer of geotextile to prevent soil or gravel from clogging the water inlet. A clay waterproof layer needs to be set below the horizontal elevation of the water inlet of the water collecting tank 1 to prevent groundwater from migrating downward.

[0020] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
