[0024] The positive circulation deslagging mode is adopted, the hole bottom is jetted with slurry, the hole is pumped to form a pressure difference, the hole wall is kept stable, and the drill pipe inner air pipe is used to blow and discharge the sediment.

[0025] 2. Membrane planting device: It includes a double mast system, two masts are vertically arranged on the working platform and can move independently to adapt to the anti-seepage membrane implanting requirements of different widths.

[0026] The power head is installed on the mast and is used to drive the drill or the wire saw to rotate and feed.

[0030] 3. Guiding device: Installed at the front end of the impermeable membrane, it is lowered to the bottom of the groove synchronously with the submersible drill, and has guiding and supporting functions to prevent the impermeable membrane from being scraped and torn to the groove wall.

[0031] The guiding device has a "Y" shaped cross section, the inner side of the arm is provided with anti-slip and buffer materials, and the outer side is used to prevent mud and debris from damaging the impermeable membrane.

[0032] The recovery mechanism includes an unhooking device and a traction mechanism, which is used to recover the guiding device after the operation is completed.

[0033] 4. Real-time monitoring system: Including platform walking leveling and hole aligning system, construction parameter monitoring system and information data transmission system.

[0036] The information data transmission system transmits monitoring data to the background or remote monitoring center in real time, realizing remote monitoring and management.

[0037] The above-mentioned equipment is used to implement the implantation method of underground impermeable membrane, which includes Grooving: Step S1.1: Use the grooving equipment to groove at the predetermined position of the underground impermeable wall. The grooving equipment is equipped with a telescopic drill rod, and the telescopic range covers 0 to 30 meters to adapt to the construction needs of impermeable walls of different depths. The high-strength alloy saw blade or diamond rope saw at the end of the drill rod is driven by a high-precision servo motor to realize stable and efficient soil cutting.

[0038] Step S1.2: Select appropriate mud parameters according to the grooving geological conditions. Ensure that the mud specific gravity is not less than 1.5 g / cm³, and adjust the mud formula in real time according to the soil hardness and humidity. For complex strata, high molecular polymer mud with better impermeability and shear strength than traditional bentonite mud is selected, and mud wall protection technology is used to maintain the stability of the groove section.

[0039] Step S1.3: Remove the sediment by using a positive cycle of deslagging. Form a pressure difference by jet grouting at the bottom of the slot and suction grouting at the orifice to maintain the stability of the hole wall. When removing sediment from the bottom of the slot, use the air pipe inside the drill pipe to aim at the sediment and blow it up and out through the deslagging pipeline, reducing disturbance to the hole wall.

[0040] S2. Membrane preparation: Step S2.1: After the slot segment is formed, perform pre-preparation work before membrane installation. Place positioning frames at the middle of the wall thickness at both ends of each wall, and accurately lower them to the predetermined position by hydraulic or mechanical means. Place two precast channel steels at both ends of the positioning frame, with the bottom inserted into the soil layer at the bottom of the hole for stability, forming a temporary working well.

[0041] Step S2.2: Install positioning blocks on one side of the working well, which are used to ensure the accurate position of the impermeable membrane during membrane installation.

[0042] S3. Membrane installation: Step S3.1: Position and level the membrane installation equipment, ensuring that it is perpendicular to the axis of the slot segment. Connect the drill pipe to the downhole drag bit, which is equipped with a membrane clamping plate connected to the drag bit by a pin or other detachable connection. Connect the impermeable membrane tightly to the membrane clamping plate, with both ends of the membrane extending about 300mm beyond the clamping plate, and the excess portion arranged with a sealing expansion strip to form a tight seal during subsequent curing.

[0043] Step S3.2: Slowly install the impermeable membrane into the slot segment by driving the downhole drag bit through the drill pipe. Monitor the tension and position of the impermeable membrane in real time during the installation process to ensure that it is wrinkle-free and does not deviate. The penetration rate is controlled within the range of 10-50 cm / min to adapt to the construction requirements of different strata.

[0044] Step S3.3: After installation, remove the positioning blocks, raise the downhole drag bit, and remove the membrane clamping plate to complete the membrane installation operation.

[0045] S4. Joint treatment of impermeable membrane: Step S4.1: Perform membrane installation for adjacent impermeable walls to ensure tight connection between the impermeable membranes of adjacent slot segments. Perform membrane installation after installing positioning blocks on the other side of the original working well.

[0046] Step S4.2: After completing the membrane installation of adjacent impermeable walls, fix the joint between the two adjacent impermeable membranes in the working well at a certain distance (e.g. 5 meters) using an electromagnetic plate. The electromagnetic plate is installed on the impermeable membrane by bolts or other fastening methods to ensure that there is no leakage at the joint.

[0047] Step S4.3: After fixing the joint of the impermeable wall, remove the precast channel steel serving as the temporary working well.

[0048] Step S4.4: After the prefabricated steel box is pulled out, cement slurry, concrete or curing agent is poured into the groove for sealing treatment. The flow and curing of the curing agent are monitored in real time during the pouring process to ensure that the sealing expansion strip at the end connection part fully expands under the action of the curing agent. After the joint treatment is completed, appearance inspection and necessary repair work are carried out on the joint.

[0049] S5. Subsequent steps: Step S5.1: Adjust the position of the equipment as needed and repeat the above steps to form a continuous underground cutoff wall structure. During continuous construction, the connection between the groove segments and the impermeability are monitored in real time to ensure that the connection between the groove segments is tight and there is no leakage.

[0050] Step S5.2: After construction is completed, the equipment is thoroughly cleaned and maintained. This includes cleaning the drill rod, saw blade or band saw, checking the hydraulic system and electrical system; at the same time, the sand content of the mud is detected, and the mud with unsatisfactory sand content is replaced or the formula is adjusted in time.

[0051] Step S5.3: The final inspection and acceptance of the continuous structure of the impermeable membrane are carried out to ensure that its impermeability meets the design requirements.

[0052] The continuous structure of the impermeable membrane formed by the above-mentioned membrane planting method has the following advantages: Strong joint, excellent impermeability: Hot melt welding is a method of melting and fusing the impermeable membrane material together by heating. This connection method makes the joint of the impermeable membrane form a continuous, seamless whole structure, effectively avoiding the problems of weak and unreliable joints and leakage points that may exist in traditional joint methods. The joint strength formed by hot melt welding is high and can withstand large tensile and shear forces, thereby ensuring the overall impermeability of the continuous structure of the impermeable membrane.

[0053] High construction efficiency: Hot melt welding equipment is easy to operate and has fast welding speed, which can significantly improve the construction efficiency of the impermeable membrane joint. Compared with other joint methods, hot melt welding does not require complex preparation and subsequent treatment, greatly shortening the construction period.

[0054] Strong adaptability: Hot melt welding is suitable for impermeable membranes of various materials and thicknesses, and can meet the needs of different underground cutoff wall constructions. At the same time, the hot melt welding equipment is small in size and light in weight, easy to carry and move, and can adapt to various complex construction environments.

[0055] Good economy: Although the initial investment of hot-melt welding equipment can be relatively high, due to its high construction efficiency and reliable joint quality, it can significantly reduce maintenance costs and repair costs caused by leakage in the long run. In addition, hot-melt welding does not require the use of additional sealing materials or adhesives, which also saves related costs.

[0056] Environmental protection: Hot-melt welding does not produce harmful substances or waste, meeting the environmental protection requirements of modern engineering. Compared with traditional joint methods, hot-melt welding reduces environmental pollution problems that may be caused by the use of sealing materials or adhesives.
