Problems solved by technology

[0003] The existing preloading method still needs to transport the soil from other places, which is inconvenient to take, and it also needs to level the soil, roll it and compact it, which is inconvenient for loading and unloading, and affects the progress of the entire project.

Embodiment Construction

[0038] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end" and "the other end" The orientation or positional relationship indicated by etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, a specific orientation, and a specific orientation. The orientation configuration and operation are therefore not to be construed as limitations of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed to indicate or imply relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified a...

Abstract

The invention discloses a vacuum surcharge water preloading method which comprises the following steps: (1) surveying and setting out, and laying main and branch water filtering and draining pipes; (2) laying an upper sand cushion layer; (3) laying a polyvinyl chloride film; a polyvinyl chloride film is laid on the top face of the sand cushion layer and isolated from the atmosphere, and the periphery of the film is buried in soil; (4) constructing a sealing ditch and setting a measurement mark; (5) installing a vacuum pump, and vacuumizing, pre-pressing and solidifying the soil layer; (6) high-quality cohesive soil is used for building a cofferdam on the thin film, and water is pumped and injected into the cofferdam for weight loading; (7) setting a settlement observation pile; (8) settlement observation and analysis; and (9) unloading the surcharge water. The vacuum surcharge water preloading method is improved on the basis of a vacuum combined surcharge preloading method, surcharge soil is replaced with water, loading and unloading are facilitated, the property of soft soil is improved, the consolidation rate is increased, the construction period and cost are saved, materials are convenient to take, time is saved, and economic benefits are high.

Description

technical field [0001] The invention relates to the technical field of soft soil reinforcement, in particular to a method for preloading water in a vacuum heap. Background technique [0002] my country's soft soil area is widely distributed, and its characteristics are: high water content, low strength, high compressibility, and it is difficult to meet the needs of engineering construction. However, with the development of the national economy, many engineering projects have to be constructed on soft soil foundations. Therefore, it must be reinforced, otherwise it will cause large settlement or even damage. [0003] The existing stacking preloading method also needs to transport the soil from other places, which is inconvenient to use, and also needs to level and compact the soil, which is inconvenient for stacking and unloading, and affects the progress of the entire project. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a method f...
