Solidifying device for blown sand type island construction

Abstract

The invention discloses a solidifying device for blown sand type island construction. The device comprises a material bin, a main sea sand pumping pipeline, and a first conveying pipeline which is provided with a spiral conveying rod and is arranged between the material bin and the main sea sand pumping pipeline, wherein a first flow meter and a first reverse stop valve are sequentially arranged on the first conveying pipeline in the conveying direction. The device has the beneficial effects that the mixing in the pumping process can be carried out at the speed equal to the pumping speed, so that the mixing efficiency is extremely improved; and meanwhile, the limitation of terrian conditions of intertidal zones is avoided, so that the construction period can be effectively reduced; the sediment pumping flow rate, the water content and the particle size of sediment can be detected in real time, and the powder materials and the sediment-water separating agent feeding quantity can be timely adjusted, so that the construction quality is ensured; the sediment particles are subjected to surface modification through a surfactant, so that the water can be accelerated to be separated out; the sediment particles are gradually close to each other as the water is separated out, and the hydration reaction of hydraulic powder materials gradually start; and the particles gradually gain the intensity.

Description

technical field [0001] The invention relates to the technical field of sand blowing and island building, in particular to a solidification device for sand blowing and island building. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] With the development of marine engineering, the speed and quality requirements for sand blowing and island building are getting higher and higher. With the input of large-scale dredging engineering ships, it has become possible to form thousands of square meters of tidal flats overnight. However, the tidal flats formed in this way often cannot form a bearing capacity within a few months due to the excessive water content of the sediment, and even construction vehicles are difficult to pass through. Putting dozens of large excavators on the tidal flats to mix hydraulic materials such as fly ash and cement in the sand is ...

Secondly, the quality of mixing depends entirely on the proficiency of the excavator operator. The quality of the project is greatly affected by human factors, and uneven mixing may lead to uneven settlement of the foundation.
