Description

Technical Field

[0001] The invention relates to the technical field of HDPE film laying construction for soil covering and sealing, in particular to a carrier frame for HDPE film laying overlapper construction and application thereof in HDPE film overlap. Background Art

[0002] At present, in environmental governance and soil remediation projects, HDPE film is mainly used to separate the treated contaminated soil from the upper backfill soil. In the vertical HDPE film laying construction of soil remediation, melt film or zipper-type jointers and locks are mainly used to overlap the membranes.

[0003] The existing technology's overlapper consists of two parts, which need to be lowered and lifted at the same time during construction, which is very inconvenient and affects the construction quality. In response to many needs in existing construction, a mounting frame for a molten film and zipper-type overlapper used in the film-to-film overlap process is provided to facilitate construction and ensure construction quality. Summary of the invention

[0004] The purpose of the present invention is to provide a HDPE film laying carrier and its application in HDPE film overlapping, which is aimed at the deficiencies in the prior art. It adopts a movable frame structure, equipped with a wire-laying roller and its motor and a film melting device, to facilitate the overlapping construction of the HDPE film and ensure the quality of film melting and overlapping, and provides an effective carrier, which greatly improves the work efficiency and construction quality.

[0005] The object of the present invention is achieved as follows: a HDPE film laying carrier, including a film melter and two pay-off rollers and their motors, wherein the film melter and the two pay-off rollers and their motors are arranged on a carrier with a frame structure, and the carrier adopts a film melting platform composed of an inverted "concave"-shaped frame structure; the two pay-off rollers and their motors are symmetrically arranged on the film melting platform; the film melter is arranged in the "concave"-shaped frame at the lower part of the film melting platform, and the wire ropes on both sides are respectively wound around the two pay-off rollers; the motor drives the rotation of the two pay-off rollers to lift the film melter from the bottom of the carrier to the film melting platform, thereby realizing the overlapping construction of HDPE film laying.

[0006] A plurality of wheels are arranged at the bottom of the carrying frame to form a movable film melting vehicle.

[0007] An application of a HDPE film laying carrier to HDPE film overlap, wherein the application of the HDPE film laying carrier to HDPE film overlap specifically comprises the following steps:

[0008] 1) Move the HDPE film laying carrier to the designated position under both sides of the HDPE film covering the soil;

[0009] 2) Turn on the switch of the motor 2, rotate the two pay-off rollers 1 to lower the film melting device 3 to the specified position;

[0010] 3) According to the construction requirements, the two pay-off rollers 1 are rotated to pull the overlapper 3 to the top of the film melting platform 6, that is, the top surface of the carrier 5, to complete the overlap construction of the two HDPE films.

[0011] Compared with the prior art, the present invention has a simple structure and is easy to construct, which greatly improves the management effect of soil covering and sealing. In order to facilitate the overlapping construction of HDPE film and ensure the melting film and overlapping quality, an effective carrying frame is provided, which greatly improves the work efficiency and construction quality, has strong practicality, and has broad promotion and application prospects.
