Problems solved by technology

Contaminated soil, groundwater, and pollution sources that may leak into the ground need to be controlled urgently. The traditional rigid underground diaphragm wall has limited anti-seepage performance and cannot tolerate special pollutants. Full of silt and seeping groundwater, people cannot proceed with HDPE geomembrane installation

Embodiment Construction

[0027] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] As shown in the figure, the underground vertical installation method of HDPE geomembrane involved in the present invention adopts the following equipment for installation, including a crane 1 and a stretching film roller 2, a stretching film frame 3, a fixed bead 4 and a fixing member, and the stretching film frame 3 It is rectangular, and the height of the stretching film frame 3 is adjusted according to the vertical installation height of the HDPE geomembrane underground. On the end surface of the lower end of the stretching film frame 3, several downward protruding teeth 5 are arranged, and the fixing member is fixed by a fixed flat steel 6 and a The fixed angle steel 7 is composed of a vertical surface and a backward oblique hook. The bottom of the fixed angle steel 7 is pointed, and a backing plate 8 is horizontally arra...

Abstract

The invention relates to an underground vertical installation method for an HDPE geomembrane. Following devices are adopted and installed according to the following steps. By means of the scheme, the method is used for controlling relocation diffusion of contaminants in contaminated soil or underground water, then a suitable comprehensive treatment method is adopted for the contaminants, the soil and the water is recovered, and leakage and diffusion of a pollution source having not been leaked are prevented. The equipment process is mature, operation is safe, the method meets the requirements of different environments, different contaminants and different contamination depths, the vertical installation depth and speed can be controlled flexibly, the installation depth and width and the descending speed in the installation process of the HDPE geomembrane can be adjusted, the installation speed, depth and perpendicularity of the HDPE geomembrane can be effectively controlled, installation is flexible and rapid, fixation of the HDPE geomembrane is achieved, the HDPE geomembrane is finally stabilized and does not float, the flatness before the HDPE geomembrane enters an underground empty slot and the perpendicularity after the HDPE geomembrane enters the underground empty slot are controlled reasonably, energy is saved, consumption is reduced, secondary pollution is not generated, and safety and environmental friendliness are achieved.

Description

technical field [0001] The invention relates to an underground installation method of an HDPE geomembrane, in particular to an underground vertical continuous rapid installation method of an HDPE geomembrane. Background technique [0002] In the prior art, with the rapid development of social economy, urbanization and industrialization are accelerating, urban garbage and industrial waste are increasing sharply, and petrochemical and mining smelting processes are putting more and more pressure on the environment. Sudden environmental pollution accidents occur frequently, the pollution characteristics are responsible, and the pollution degree is relatively deep. Contaminated soil, groundwater, and pollution sources that may leak into the ground need to be controlled urgently. The traditional rigid underground diaphragm wall has limited anti-seepage performance and cannot tolerate special pollutants. Full of silt and seeping groundwater, people cannot proceed with HDPE geomemb...
