Embodiment approach

[0034] This embodiment provides a method for implementing a self-priming semi-permeable membrane drainage network, including the following steps:

[0035] Step 1: Transport the solidified soil with high water content to the embankment filling place, fill half of the required height of the embankment, and then lay a self-priming semi-permeable membrane drainage network on the half-filled embankment 9 . like Figure 4 As shown, the top surface of the embankment 9 filled with half the height has a certain inclination, the liquid injection port 6 of the drainage net is located on the higher side, and the length of the PVC pipe 7 arranged laterally is greater than the width of the embankment 9, so The liquid injection port 6 exceeds the side of the embankment 9. In this embodiment, the inclination is 5-10°.

[0036] Step 2: Pour sulfurous acid pulp waste liquid 4 into the PVC pipe 7 of the drainage network through the liquid injection port 6 until the sulfurous acid pulp waste li...

Embodiment 2

[0041] Step 1. Transport the solidified soil with high moisture content to the embankment filling place, fill half of the height first, and make a self-priming semi-permeable membrane drainage network. The length of the horizontal PVC pipe 7 of the self-priming semi-permeable membrane drainage network depends on the width of the embankment, and it is greater than the embankment 9 width 2m, and the length of the longitudinal PVC pipe 7 is 14m, and the diameter of the PVC pipe 7 is 5cm. On the wall, an electric drill is used to displace and open permeation holes 5 with a diameter of 3 cm, and the interval between the permeation holes 5 is 5 cm. The outside of the PVC pipe 7 is wrapped with a semi-permeable membrane 1 made of polyvinyl alcohol, and the outside of the semi-permeable membrane 1 is wrapped and fixed with barbed wire or a synthetic resin net.

[0042]Step 2. Laying a self-priming semi-permeable membrane drainage network on the embankment 9 filled with half the height...

Abstract

The invention discloses a self-priming semi-permeable membrane drainage network, which comprises PVC pipes connected vertically and horizontally; One end is opened as a liquid injection port; a number of permeable holes are opened on the PVC pipe, and the outer surface of the PVC pipe is wrapped with a semi-permeable membrane. It also discloses the implementation method of the self-priming semi-permeable membrane drainage network, relying on the osmotic pressure of the solution inside and outside the PVC pipe, so that the water in the soil passes through the semi-permeable membrane and enters the pipeline to be discharged, and multiple PVC pipes drain at the same time, increasing the drainage area. The drainage process is simple and efficient, saving manpower and material resources, and the drainage efficiency is high, which effectively promotes the increase of the bearing capacity of the foundation. And there is no dust pollution in the process of rapid water reduction, the used sulfurous acid pulp waste liquid is non-toxic, highly viscous, not easy to seep out from the semi-permeable membrane, has good osmotic pressure, and meets environmental protection requirements.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a self-priming semi-permeable membrane drainage net and an implementation method thereof. Background technique [0002] At present, one of the main ways of resource utilization of high water content silt excavated in engineering is to use it as embankment filler. Generally, the muddy soil is transformed into high-quality soil that meets the strength and deformation requirements of embankment filler by first reducing water and then solidifying. . One of the water reduction methods is air drying, which does not require much manpower and material resources, but completely relies on natural evaporation to reduce water, and is limited by weather conditions, the water reduction speed is slow and the efficiency is low, which seriously affects the later curing progress and construction process; In addition, the chemical water reduction method is used to achieve the...
