With the acceleration of urbanization construction, urban land resources are scarce, and a large amount of building space needs to extend underground, particularly rail transit, large shopping malls, office buildings, parking lots and the like; the underground continuous wall is one of the most suitable construction schemes for underground space construction, and has the advantages of high construction speed, stable quality, good safety and reasonable cost; the construction of the underground continuous wall is generally carried out by constructing a groove with certain width and depth according to the design requirement through a double-wheel milling or grooving machine, and the width is generally 3-6 meters; reinforced concrete is poured to form an underground wall, the underground wall is formed by connecting the walls one by one, in order to prevent the water leakage of a joint between the walls, the joint of the underground continuous wall generally adopts a cross-shaped steel embedded part to form a concave-convex construction groove, the concave-convex groove is firstly filled with a sand bag, a guide pipe and a joint box during each construction, the filler is withdrawn after concrete is solidified to form a water-stop groove for the next wall, the most mature filling measure or sand bag is used, the bagging and throwing filling accumulation of one construction needs more than 10 persons for 1 day, a large amount of mechanical throwing matching wastes time and labor; there are also steel boxes, which lock the tubes but are limited in depth.

The inside and outside mechanisms and construction units research the underground continuous wall joint filling construction technology:

the authorization notice number is CN104278697B, the slurry bag for sealing and filling the space of the underground continuous wall head is vulcanized by rubber and fiber reinforced layers, the section of the slurry bag is trapezoidal slurry entering and exiting at the bottom, and the like; in actual use, design defects are completely exposed, the slurry bag is formed by vulcanizing rubber and a fiber reinforced layer, the underground continuous wall reinforcement cage is extruded to displace along with the increase of pressure due to elastic deformation after pressurization, the concrete flows around after the pressure of the bag body is small, and the concrete flows into a space to be filled; slurry is opened when entering and exiting the lower tank through a bottom valve and is closed when falling into the bottom, the operation is inconvenient in practical operation, the sealing is not tight, and a bag cannot be taken out after the concrete flows around, so that the reinforcement cage of the next wall cannot be installed according to the designed position due to the concrete flows around, a subsequent joint leaks water, huge cost treatment and project progress delay are taken afterwards, and serious hidden danger is left;

although the flexible liquid bag filled in the end space of the underground continuous wall with the application publication number of CN110424374A/CN110424375A adopts a multilayer structure, the design is that a vulcanized layer is added to a Kevlar liner, according to the specification, the Kevlar liner only has the functions of increasing strength, resisting abrasion and tearing, and the outer layer is still made of rubber and fiber, rubber cord fabric or rubber, fiber and cord fabric; in the actual use process, the friction and the pressure of the bag are mainly between the outer surface and the wall of the bag, the Kevlar is arranged in the bag and cannot achieve the expected strength, wear resistance and tear resistance effects, the supporting component is arranged in the bag, the operation difficulty is increased, and the stress state and the stress degree between the bag and the supporting component are difficult to master; the pouring speed provided in the scheme can not exceed 6 m/h, and the construction time of a wall with the depth of 40 m is increased by 2-4 times compared with the original wall; the alarm pressure is 2.6 kg, the general volume of the filling bag is 10-100 cubic, the actual instantaneous pressure reaches more than 4 kg, and the design and processing materials of the bag are required to be high.
