Soft soil combined preloading structure and construction method
The invention relates to the technical field of civil engineering, and discloses a soft soil combined preloading structure and a construction method. The soft soil combined preloading structure is used for preloading soft soil near land and water, and comprises multiple drain plates vertically inserted in the soft soil, a partition layer covering the upper end surface of the soft soil, and a cofferdam arranged along the outer edge of the partition layer, wherein the cofferdam and the partition layer are enclosed to form a water storage space capable of providing preloading force to the soft soil after the water storage; a vacuum pipeline is arranged in the partition layer; and the upper ends of the drain plates are communicated to the vacuum pipeline. The soft soil combined preloading structure uses water for replacing soil to preload without specially planning the stacking construction process, is short in working period, low in cost and simple in construction process, can change the height of the cofferdam to adjust the magnitude of the preloading force, and sucks the soft soil through the fit between the drain plates and the vacuum pipeline, so that the whole soft soil preloading process is quicker.
