Description

Permeable pipe for side slope

Technical Field

The utility model relates to the technical field of slope drainage, in particular to a permeable pipe for a slope.

Background

The drainage of the slope refers to the work of draining the surface water in the slope rock body. An important inducer of landslide occurrence is the action of water. The water applies dynamic water pressure, hydrostatic pressure and physical and chemical action to the rock mass of the side slope to weaken the strength of the rock mass, so that the side slope is unstable and slides, and drainage is an extremely important measure for preventing the side slope from sliding. Therefore, the drainage of the side slope influences the stability and the safety of the side slope engineering, and if the side slope supporting structure is damaged due to improper treatment, the instability is generated.

At present, the most common arrangement for treating the underground water of the side slope is to use a soft permeable pipe as a drainage structural member. However, the permeable pipe made of soft materials is easy to collapse to cause clogging under a long-term working state due to insufficient strength of the materials, and no effective means can deal with the clogging problem at present, so that the clogging seriously affects the drainage effect. In addition, the arrangement of the existing permeable pipe structure is basically omnibearing permeable, and the structure has weak drainage capacity, so that water is easily discharged from a hole with a low horizontal position under the action of gravity and is discharged to a soil layer instead of being discharged from a fixed pipeline. Therefore, it is necessary to provide a water permeable pipe having clogging prevention and strong drainage ability.

The utility model aims to solve the problems that the existing water permeable pipe is easy to block and has weak water permeable capacity. The utility model provides a permeable pipe of a side slope aiming at a drainage system of the side slope so as to achieve the purposes of preventing the permeable pipe from being blocked and improving the drainage efficiency of the side slope.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

The upward inclined drainage means that deep underground water is discharged in the slope by adopting a small-diameter drainage pipe. The structure can quickly drain underground water, improve the shear strength of a rock-soil body, prevent the instability of a side slope, and has less excavation of the rock body, quick engineering progress and low cost. It follows from the experiment that when the tilt ratio is set to 1: at 10, the drainage effect is best.

The water permeable pipe comprises a water permeable main body 100, the water permeable main body 100 comprises a water draining pipe 110, and the water draining pipe 110 is made of any one of PVC, PPR and antirust steel.

The drain pipe 110 has multiple sections, and the two sections are fixedly connected through a connecting piece 113, and the connecting piece can be in groove type connection or hot melt connection. The groove type connection is also called as a clamp connection, and can be used for connecting galvanized steel pipes with the diameters of more than or equal to 100mm of systems such as fire water, air conditioner cold and hot water, water supply, rainwater and the like. The method has the characteristics of simplicity in operation, no influence on the original characteristics of the pipeline, safety in construction, good system stability, convenience in maintenance, labor and time saving and the like. The hot melting connection is realized by using a heating mode, so that the PPR connection part reaches a melting point to generate melting, and the pipe are fused together by using a socket joint mode. The hot-melt connection is a permanent connection with high reliability, and water leakage accidents hardly occur once the hot-melt is completed.
