secondly, spreading the anti-seepage material on the ground, enabling the anti-seepage material to be tightly attached to the ground, the pan bottom and the groove, vertically placing the support on the side lines of the plurality of bee lattices, and mutually fixing the support to form an integral framework;
thirdly, forming the rope net with proper size into the inner surface of a lattice along the support, wherein the rope net naturally sags after the laying is finished, and the bottom of the rope net is tightly attached to the pot bottom on the ground; cutting the anti-seepage material into a square shape, lifting the four corners of the anti-seepage material by using a crane, placing a steel ball at the center to enable the center of the anti-seepage material to naturally droop, moving the crane to align the drooping part of the center to the center of the pan bottom, slowly lowering the anti-seepage material to enable the anti-seepage material to naturally droop and cling to a rope net, wherein the length of the anti-seepage material is larger than that of the support, the part of the anti-seepage material, which exceeds the support, naturally droops, and the drooping anti-; then, taking the steel ball out, placing the water accumulation groove into the bottom of the pot until one bee lattice is completely installed;
and fourthly, repeating the third step until most of the bee lattices are laid, laying impermeable materials in the grooves around, overlapping the impermeable materials with the first-step ground laying, and collecting water when leakage occurs to avoid leakage into the foundation, so that pollution and foundation deformation are avoided.
The impermeable material is geomembrane, plastic cloth or waterproof cloth.
The barrier material is in one piece, without seams, and its exterior is protected by a netting.
The fracturing soft tank is prepared by the construction method of the fracturing soft tank.
The invention has the beneficial effects that: simple structure, convenient construction, safety, reliability and low cost.

In the figure: 1 ground impermeable cloth, 2 ground grooves, 3 pillars, 4 supports, 4-1 bee-lattice transverse supports, 4-2 bee-lattice longitudinal supports, 4 supports, 5 rope nets and impermeable cloth, 6 pot bottoms, 7 water collectors, 8 rectangular water outlets and 9 water collector shells.
Detailed Description
The invention will be described in further detail with reference to the following drawings and specific embodiments, but the scope of the invention as claimed is not limited to the scope of the embodiments:
as shown in figures 1-4, the construction method of the fracturing soft tank adopts the forms of support, rope net stress, impermeable cloth sealing and bottom pot bottom water accumulation, and adopts the following modes:
in the figure, 1 ground impermeable cloth, 2 ground grooves, 3 pillars, 4 supports, 4-1 bee lattice transverse supports, 4-2 bee lattice longitudinal supports, 4 supports, 5 rope nets and impermeable cloth, 6 pan bottoms, 7 water accumulators, 8 rectangular water outlets and 9 water accumulator shells are arranged.
Firstly, plowing the available land to be loose with the depth of 30-40 cm, flattening the land after removing large stones or other hard objects, digging a groove with the depth of 20-30 cm at the periphery, uniformly dividing the land in the groove into 9 blocks, calculating a bee space for each block, drawing lines at the edges of the bee spaces, slightly raising the periphery of each bee space, digging a pot bottom at the center, and paving the pot bottom on the pot bottom by using soft soil or fine sand with the thickness of 3-5 cm.
And secondly, spreading an impermeable material (geomembrane, plastic cloth or other waterproof cloth) on the ground, and tightly attaching the impermeable material to the ground, the pot bottom and the groove. The support is vertically placed on the sidelines of the 9 small blocks and mutually fixed to form an integral framework.
And thirdly, laying the rope net with proper size along the inner surface of a lattice formed by the supports, wherein the rope net naturally sags, and the bottom of the rope net is tightly attached to the pot bottom on the ground. The anti-seepage cloth is cut into a square shape, four corners of the anti-seepage cloth are lifted by a crane, a steel ball is placed at the center of the anti-seepage cloth, the center of the anti-seepage cloth naturally sags under the action of gravity of the steel ball, the central sagged part of the anti-seepage cloth is aligned to the center of the bottom of the pan by the mobile crane and slowly lowered down after the central sagged part of the anti-seepage cloth is aligned to the rope net, the length of the anti-seepage cloth is larger than that of the support and exceeds that of the support to naturally sag, and the anti-. Then, the steel ball is taken out, and the water accumulation groove is placed at the bottom of the pan body. And finishing the installation of one bee lattice.
And fourthly, repeating the third step until 9 bee lattices are laid. And laying anti-seepage cloth in the peripheral grooves, and overlapping the anti-seepage cloth with the earliest laid anti-seepage cloth on the ground. When leakage occurs, water can be collected, and pollution and foundation deformation caused by leakage into the foundation are avoided.
Fifthly, when water is stored, each bee lattice is relatively independent and is provided with a pipeline respectively and serves as a water inlet, and when water is added, all the bee lattices can add water simultaneously or sequentially.
