Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a pair of mutually connected drainage holes. Background Art

[0002] For areas with developed groundwater and abundant rainfall all year round, excessive moisture content of fill behind slope protection or retaining wall will lead to increased water and soil pressure. In severe cases, it will cause large displacement and deformation of slope protection or retaining wall, or even collapse. Therefore, for the retaining wall drainage system in such areas, it is necessary to ensure that the drainage holes are stable and effective for a long time without clogging. At present, the drainage holes of retaining walls are all buried with PVC pipes, and permeable materials are used as anti-filter layers at the water inlet on the back of the wall to filter sediment. However, the construction of the anti-filter layer is relatively cumbersome and the quality is difficult to guarantee. After a period of time, the drainage holes are often blocked, making it difficult to maintain and repair them in the later stage. Utility Model Content

[0005] A water outlet pipe is arranged on the water leakage hole and is used for discharging water.

[0006] A vertical drain pipe is arranged on the water outlet pipe and is used for collecting water.

[0007] A longitudinal connecting pipe is arranged on the water outlet pipe to expand the drainage range.

[0008] Preferably, the water outlet pipe and the longitudinal connecting pipe are both provided with semi-permeable hole walls for increasing the drainage volume, and the semi-permeable hole walls are opened in the upper part of the water outlet pipe.

[0009] Preferably, the vertical drain pipe is provided with a full water seepage hole wall for increasing the water inlet, and the vertical drain pipe is entirely provided with the full water seepage hole wall.

[0010] Preferably, a flow-balancing baffle is provided on the longitudinal connecting tube, which is used to control the water flow and ensure the smooth flow of the water. The flow-balancing baffle is welded on the inner side of the longitudinal connecting tube.

[0012] Preferably, the connection between the water outlet pipe, the vertical drainage pipe and the longitudinal connecting pipe is in a round-bottomed concave shape, which ensures that water will not accumulate and the problem of small water flow unable to gush out will not occur.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the interconnected drainage holes form a drainage network, and through the water permeability of the pipe wall, it can not only quickly discharge the water seepage on the back of the retaining wall, but also ensure that the drainage holes of the retaining wall will not be blocked under long-term work, reducing the difficulty of later maintenance, and also improving the overall stability of the roadbed.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1As shown, the utility model provides a technical solution: a kind of interconnected drainage holes, which are arranged on the wall, the wall is provided with drainage holes, the interconnected drainage holes are wrapped with non-woven geotextiles, and are used to filter gravel, including: an outlet pipe 1, a vertical drainage pipe 2 and a longitudinal connecting pipe 3, the outlet pipe 1 is arranged on the drainage hole, and is used to discharge water, the outlet pipe 1 and the longitudinal connecting pipe 3 are provided with a semi-permeable hole wall 11, which is used to increase the drainage volume, the semi-permeable hole wall 11 is opened in the upper half of the outlet pipe 1, and one end of the outlet pipe 1 extends The inlet drain hole has a smaller pipe diameter than the drain hole diameter, and the slope is consistent with the drain hole slope. The other end is integrally connected to the vertical drain pipe 2 and the longitudinal connecting pipe 3 in one step. The outlet pipe 1 and the vertical drain pipe 2 are vertically connected to the upper longitudinal perforated corrugated pipe interlayer. The interlayer connection is adjacent to each other when connected to form a drainage network, which effectively relieves the drainage pressure of the bottom water pipe.
