Method for efficiently absorbing water and solidifying under films through controllable vacuum negative pressure well
A controllable, negative pressure well technology, applied in infrastructure engineering, soil protection, construction, etc., can solve the problem that a single set of vacuum pumping equipment has a small influence range, does not consider the fluid mechanics characteristics of the pipeline, and has a large vacuum pressure transmission loss. and other problems, to achieve the effect of easy to master the construction process, significant economic effect, and high drainage efficiency.

Embodiment 1
[0055] In this embodiment, a negative pressure sealing well is arranged in the center of the site for the deep treatment of general soft soil, such as Figure 1 to Figure 3 shown.
[0056] The implementation process is as follows:
[0057] Before implementing the above-mentioned reinforcement method, the surface of the site should be cleared and the defense line should be measured.
[0058] Then start to implement the above reinforcement method, and the points that need specific attention are as follows:
[0059] In the first step, hydraulic or vibratory machinery is used to drill the drainage board, and the drainage board is arranged in a square or plum blossom shape.
[0060] In the second step, the horizontal pipeline is laid in the sand cushion layer 20 with a thickness of 30-50 cm.
[0061] In the fourth step, the water inlet of the sealed well is sealed and communicated with the main pipe and the branch pipe respectively.
[0062] In the fifth step, the non-woven geo...
Embodiment 2
[0065] In this embodiment, a negative pressure sealing well is arranged on one side of the site for the deep treatment of general soft soil, such as Figure 4 , Figure 7 , Figure 8 shown.
[0066] The implementation process is basically the same as in Example 1, the difference is:
[0067] In the fourth step, the water inlet of the sealed well is sealed and connected with the main pipe.
Embodiment 3
[0069] In this embodiment, a negative pressure sealing well is arranged on one side of the site for the deep treatment of general soft soil, such as Figure 5 , Figure 7 , Figure 8 shown.
[0070] The implementation process is basically the same as in Example 1, the difference is:
[0071] In the third step, the horizontal pipeline is laid on a layer of braided cloth 5 .
[0072] In the fourth step, the water inlet of the sealed well is sealed and connected with the main pipe.
