Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0024] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0025] In a technical solution, such as figure 1 , 2 As shown in , 3, the treatment methods for large-area ultra-soft soil foundation in ports include:

[0026] Step 1, laying a sand cushion 1 above the supersoft soil foundation;

[0027] Step 2. Vertically lay multiple sets of drainage pipes 4 in the ultra-soft soil foundation, each group of drainage pipes 4 includes a plurality of drainage pipes 4 distributed in a ring, and the drainage pipes 4 include a main pipe and a plurality of wing plates 401. A plurality of first openings are formed on the side wall of the main pipe. ...

Abstract

The invention discloses a large-area ultra-soft soil foundation treatment method for a port, comprising the following steps: 1, laying a sand cushion layer on an ultra-soft soil foundation; 2, vertically piling a plurality of groups of drainage pipes in the ultra-soft soil foundation, wherein each group of drainage pipes comprises a plurality of drainage pipes distributed in a ring shape; 3, vertically piling a center cylinder at the center of each group of drainage pipes, wherein a rotating shaft is coaxially disposed inside each center cylinder, and is supported by two bearing seats, and aneccentric wheel is further fixed on each rotating shaft; 4, drugging an annular sealing groove at the periphery of each group of drainage pipes, and then paving a sealing film on the sand cushion layer and in each sealing groove; 5, connecting the upper end of a main pipe to a vacuum pump through a connecting pipe, performing a vacuuming process, and connecting the rotating shafts with a motor torotate the rotating shafts and the eccentric wheels; 6. after the vacuuming process is finished, removing the sealing films, the connecting pipe and the motor. The large-area ultra-soft soil foundation treatment method can increase the drainage speed and reduce the possibility of clogging of the drainage pipes.

Description

technical field [0001] The invention relates to a foundation construction method. More specifically, the invention relates to a treatment method for large-area ultra-soft ground in ports. Background technique [0002] The ultra-soft soil foundation has the characteristics of high water content and low strength, and it is generally treated by vacuum preloading method at present. However, the current vacuum preloading method has a slow drainage speed, and as the construction time increases, the drainage board is more likely to be blocked, which affects the later drainage capacity. Therefore, there is an urgent need to provide a treatment method for ultra-soft ground that can overcome the above-mentioned defects to a certain extent. Contents of the invention [0003] An object of the present invention is to provide a method for treating large-area ultra-soft soil foundations in ports, which can increase drainage speed and reduce the possibility of drainage pipe clogging. ...
