Method for building artificial island and pile foundation bearing platform workbench through waste boxing and stacking

Abstract

The invention relates to a method for building an artificial island and a pile foundation bearing platform workbench through waste boxing and stacking. The method is characterized by comprising the following steps that garbage slag powder is filled into sealed boxes, and vibrating and compacting are carried out on the garbage slag powder by using a vibrating table to form permanent sealed boxes; the sealed boxes are hoisted into water by using a crane to form the artificial island in a stepped stacking manner, wherein a plurality of water pipes are preset at the lower part of the artificial island; a steel cofferdam is fixed at a preset position, and the sealed boxes are stacked around the outer wall of the steel cofferdam to form the artificial island; bottom sealing needs to be conductedin the steel cofferdam, it is guaranteed that dry operation is conducted after water pumping, and cement water glass soil balls are adopted for bottom sealing; and pile positions are preset in the steel cofferdam, steel pile casings are inserted into the pile positions, outer walls of steel pile casings are used for filling of the workbench, and after pile construction is completed, excavation isfacilitated for bearing platform construction. According to the method, water construction is changed into land construction, use of large equipment is facilitated, efficiency is improved, quality and safety are easy to control, and the construction cost is effectively reduced.

Description

technical field [0001] The invention relates to a method for building an artificial island and a pile foundation cap workbench by packing waste into piles. Background technique [0002] At present, there are three construction plans for building bridges on the water surface, building islands with mountain stones, building islands with clay and adding rotary grouting piles, and steel temporary bridges and steel platforms for reference. The rotary grouting method for filling soil is not only time-consuming and uneconomical, but also pollutes the river, which is obviously not feasible. However, the mountain stone filling is a relatively feasible solution. The first problem is that the workload is heavy, the time is long, the cost is high, waste cannot be used, and it is not environmentally friendly. There are also many difficulties in the construction process. If it is carried out in the middle, it will take a lot of effort to isolate or stop the water, which is basically not ...
