Problems solved by technology

[0003] The existing cutting method of the nailed geomembrane is to fix the nailed geomembrane on the formwork, and then trim and trim it, so the cutting accuracy is not high; at the same time, the cutting accuracy requirements for the nailed geomembrane High special case, the above method cannot trim the embedded geomembrane after cutting
[0004] Therefore, in order to prevent grout leakage caused by misaligned joints and large cracks during concrete pouring and affect the quality of concrete pouring, it is necessary to achieve accurate dimensions when cutting the embedded geomembrane without secondary trimming

Embodiment 1

[0054] The invention provides a method for precisely cutting a 2m*6m size embedded geomembrane membrane block, including:

[0055] Step 1. Manufacture the splicing unit of the cutting tool according to the cutting size requirements, that is, the width is 1 / 2H=1m, and the length is 1 / 2L=1.5m.

[0056] Step 2. Clean up the cutting platform to ensure that the cutting operation platform is clean, dry, firm and flat, without unevenness, sundries and sharp objects, without slope, and the space should not be less than 4m*8m.

[0057] Step 3. Flatten the nail-embedded geomembrane and place it on the cutting platform, with the nail-embedded side facing down. After the nail-embedded geomembrane is flattened, it should be flat and free of warped edges. Flatten and compact the nail-embedded geomembrane The film width is 2.44m (width), and its length should be 7m.

[0058] Step 4. Splice the four cutting tool splicing units to obtain a cutting tool with a size of H=2m and L=3m; fix the tw...

Embodiment 2

[0063] The invention provides a method for precisely cutting a 2.44m*3.352m size embedded geomembrane membrane block, including:

[0064] Step 1. Manufacture the splicing unit of the cutting tooling according to the cutting size requirements, that is, the width is 1 / 2H=1.22m, and the length is 1 / 2L=1.676m;

[0065] Step 2. Clean up the cutting platform to ensure that the cutting operation platform is clean, dry, firm and flat, without unevenness, sundries and sharp objects, without slope, and the space should not be less than 5m*5m;

[0066] Step 3. Flatten the nail-embedded geomembrane and place it on the cutting platform, with the nail-embedded side facing down. After the nail-embedded geomembrane is flattened, it should be flat and free of warped edges. Flatten and compact the nail-embedded geomembrane The film width is 2.44m, and its length should be 4m;

[0067] Step 4. Splicing the four cutting tool splicing units to obtain a cutting tool with dimensions H=2.44m and L=3...

Abstract

The invention discloses a cutting device and method for a nailed geomembrane. The cutting device comprises a cutting tool and a sliding cutter, wherein the cutting tool is of a rectangular structure and is used for pressing the flattened nailed geomembrane on a cutting platform; and the sliding cutter is installed on at least one side edge of the cutting tool and used for cutting the nailed geomembrane. According to the cutting device and method, the nailed geomembrane can be accurately cut, and multiple times of measurement and trimming are not needed; and tool positioning is adopted, one-step cutting can be achieved, and the labor cost and the time cost are saved.

Description

technical field [0001] The invention relates to the technical field of geomembrane cutting, in particular to a cutting device and a cutting method for an embedded geomembrane. Background technique [0002] As a HDPE geomembrane with a special structure, the embedded geomembrane is mainly used to protect concrete from pollution or corrosion of toxic, harmful or corrosive substances outside. It is a kind of anti-leakage and anti-erosion protection material commonly used in concrete. . [0003] The existing cutting method of the nailed geomembrane is to fix the nailed geomembrane on the formwork, and then trim and trim it, so the cutting accuracy is not high; at the same time, the cutting accuracy requirements for the nailed geomembrane In special cases with a high level, the above method cannot trim the embedded geomembrane after cutting. [0004] Therefore, in order to prevent grout leakage caused by misaligned joints and large cracks in the process of concrete pouring, and...
