Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a pile plate wall.

Example 1

Referring to fig. 1, a pile-slab wall includes a plurality of vertically arranged piles 1, and a plurality of walls 2 connected to the piles 1 for blocking a soil layer. The lower extreme of pile body 1 sets up in the slope and wears to be equipped with many anchor rods 11 that are used for increasing pile body 1 stability in pile body 1, and anchor rod 11 slope downwardly extending just keeps away from the one end of pile body 1 and is fixed in the slope, and adjacent anchor rod 11 is parallel to each other. The wall 2 is of a plate-shaped structure and one side surface of the wall facing the pile body 1 is connected to the pile body 1.

Meanwhile, when the wall body 2 blocks a slope soil layer, moisture in the slope is also blocked, and the water content in the slope is increased, so that the slope soil layer close to the sheet pile wall is loosened, and the supporting effect of the sheet pile wall after long-term use is reduced due to the increase of the stress of the sheet pile wall.

Therefore, a drainage module 3 is provided in the wall body 2, and the drainage module includes a plurality of drainage pipes 31 penetrating the wall body 2 for drainage and a reverse filtering layer 32 for reducing soil layers in the slope from being drained by the drainage pipes 31. The drain pipes 31 are communicated with the spaces on two sides of the wall body 2, and the centers of the water outlets of the adjacent drain pipes 31 are not at the same horizontal height and are not on the same vertical line. In order to increase the drainage performance of the drain pipe 31, the drain pipe 31 is arranged obliquely, the horizontal height of the water inlet of the drain pipe 31 is higher than that of the water outlet of the drain pipe, and the inclination angle of the drain pipe 31 is not less than 5 degrees.

Referring to fig. 2, the back filter layer 32 is made of pebbles and sand gravel and is disposed in the drain pipe 31, the back filter layer 32 is wrapped by a wrapping layer 321, and the wrapping layer 321 may be made of non-woven fabric.

The implementation principle of the embodiment 1 is as follows: the pile body 1 vertically buried in the slope body can stabilize the soil layer at the lower part of the slope body to a certain degree, and the wall body 2 fixed on the pile body 1 can block the upper soil layer on which the slope body easily slides, so that the slope structure is supported, and the anchor rods 11 penetrating through the pile body 1 and fixed in the slope body can enhance the structural stability of the pile body 1. Meanwhile, the inclined drain pipe 31 can drain the moisture in the slope body in time, and the moisture backflow is relatively difficult to generate, so that the capability of draining the moisture in the slope body is improved. The inverted filter 32 arranged in the drain pipe 31 can reduce the condition of taking out soil during drainage, and the wrapping layer 321 made of non-woven fabrics wraps the inverted filter 32, so that the structure of the inverted filter 32 is relatively more stable, and the inverted filter 32 is relatively difficult to damage.

Example 2

Referring to fig. 1 and 3, the present embodiment is different from embodiment 1 in that a water penetration assembly 4 for increasing the drainage performance of a drain pipe 31 is provided at one end of the drain pipe 31 facing a slope. The water seepage assembly 4 comprises a fixed frame 41 connected to one side of the wall body 2 and a water seepage plate 42 for water seepage. The water-permeable plate 42 is parallel to and fixed to the fixed frame 41, and the inlet of the drain pipe 31 is located in a space surrounded by the fixed frame 41.

In order to reduce the deformation of the water seepage plate 42 after being extruded by the slope soil layer, a plurality of reinforcing ribs 43 and supporting ribs 44 for slowing down the deformation of the water seepage plate 42 are fixedly connected to one side of the water seepage plate 42 facing the wall body 2. The supporting ribs 44 are vertically arranged and have a strip-shaped structure, two ends of the supporting ribs 44 are respectively connected to the frame edge of the fixing frame 41, and two length edges of the supporting ribs 44 are respectively fixedly connected to the water seepage plate 42 and the wall body 2.

The reinforcing rib 43 is a strip-shaped structure, and two ends of the reinforcing rib are respectively connected to the supporting ribs 44 of the frame edge of the fixed frame 41, the reinforcing rib 43 is obliquely arranged, one end of the reinforcing rib 43 connected to the frame edge of the fixed frame 41 is higher than one end of the reinforcing rib 44, and two length edges of the reinforcing rib 43 are respectively and fixedly connected to the water seepage plate 42 and the wall body 2. In order to make the reinforcing rib 43 not only support the water-permeable plate 42 but also have water permeability, a vertical water through hole 431 is opened on the reinforcing rib 43.

Referring to fig. 3, the water seepage plate 42 is provided with a plurality of water seepage holes 421, the water seepage holes 421 are of a square structure, and a blocking piece 422 is arranged on one side of the water seepage holes 421 facing the wall 2, and the edge of the blocking piece 422 is bent towards the water seepage holes 421 and is connected to the edge of one side opening of the water seepage holes 421. Meanwhile, in order to reduce the effect of water seepage caused by the blockage of the water seepage holes 421 by soil, a geotextile 423 for filtering is connected to one side of the water seepage plate 42, which is far away from the wall body 2.

The frame edge of the fixed frame 41 close to the drain pipe 31 is in an arc-shaped structure, the opening edge of the water inlet of the drain pipe 31 is tangent to the arc edge of the arc-shaped frame of the fixed frame 41, and the drain pipe 31 is positioned at the lowest end of the fixed frame 41.

The implementation principle of the embodiment 2 is as follows: the water seepage plate 42 is placed in the slope body through the fixing frame 41, and when the water in the slope body is more, the water can seep into the fixing frame 41 from the water seepage plate 42 and flow into the water drain pipe 31 to be discharged. The reinforcing ribs 43 can support the water seepage plate 42, so that the deformation of the water seepage plate 42 after being extruded by a slope body is reduced, and the water seepage into the water seepage plate 42 can be accelerated to be discharged by the inclined arrangement of the reinforcing ribs 43 and the water through holes 431 formed in the reinforcing ribs 43, so that the possibility that water seeps back into the slope body again is reduced. And the retaining sheet 422 that infiltration hole 421 one side set up and set up geotechnological cloth 423 outside infiltration board 42 can reduce soil entering infiltration hole 421 or in the outlet pipe 31 at the in-process of infiltration, thereby lead to the condition of jam and messenger infiltration and the performance decline of drainage. The lower frame of the fixing frame 41 is formed in an arc shape so that the permeated water is gathered at the lower end of the arc and is drained through the drain pipe 31, thereby reducing the situation that the water is accumulated in the water seepage assembly 4 and cannot be drained in time to cause the water to be seeped back.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
