[0023] A vacuum preloading film pressing ditch-digging film integrated construction method, comprising the following steps: S1, site clearing and leveling; S2, setting a sealing film at both ends of the to-be-dug ditch, and installing a traction strip at the end of the sealing film; S3, starting the operation of the machine, the machine digs the soil at the front end to form a ditch, the machine drags the sealing film to a fixed position in the middle part, and then the sealing film is pressed into the soil at the bottom of the ditch by a pressing device; S4, after the machine completes the construction, checking whether the sealing film is completely and densely pressed into the soil, and selecting whether to backfill the dug soil into the film pressing ditch according to the actual situation, such as the selected construction method, the current underground water level and the like.

[0024] Specifically, the width and depth of the vacuum preloading sealing ditch will be different due to specific engineering conditions. Generally, the width of the sealing ditch is usually about 0.8m to 1.2m. The depth of the sealing ditch is usually dug to about 0.5m to 1.0m below the top surface of the impermeable layer to ensure good sealing effect, prevent air and water from entering the vacuum preloading area, and affect the reinforcement effect. In this example, the width of the sealing ditch is 1m and the depth is 1.5m.

[0025] In the S1 step, the specific steps of the site clearing and leveling are: S11: picking up and cleaning the sundries on the surface of the site, and leveling the site according to the design elevation to facilitate the entry and walking of the machine.

[0026] In the S2 step, the specific steps of setting the sealing film at both ends of the to-be-dug ditch and installing the traction strip at the end of the sealing film are: S21: laying the sealing film along the advancing direction of the ditch on the left and right sides of the to-be-dug ditch, appropriately curling the part of the sealing film along the edge of the ditch to increase the strength of the part, and then inserting the traction strip into the cavity of the traction device in the traction device figure and fixing the part of the traction strip that is inserted out of the traction device to the ground surface with a wooden stick or the like. Figure 2 The traction strip 16 in the traction device figure is installed on the outside of the part, the traction strip of the starting section is inserted into the cavity of the traction part 10 and extends out a distance, and the part that extends out is fixed to the ground surface with a wooden stick or the like. The width of the excavated ditch is 1m, two traction devices can be symmetrically arranged with a spacing of 0.6m, and the front end of the traction part at the bottom of the traction device is arranged to be inclined to the left or right side according to its position on the left or right side of the machine. The working principle of this part is similar to that of using a binding clip to hold several a4 papers together. The traction strip plays a role in holding the sealing film along one side of the ditch, and the outer surface of the traction strip is wide at the edge and narrow inside, which can be inserted into the cavity of the traction part below the traction device. For example, Figure 2 The traction part 10 in the traction device figure has an obtuse angle shape, an internal cavity for inserting the traction strip, a rear end part parallel to the advancing direction of the ditch, and a front end part inclined to the side of the ditch. As the machine moves forward, the sealing film that has been pressed into the soil at the rear end plays a fixing role, so the part of the sealing film in the advancing direction will be pulled into the sealing ditch under tension.
