Abstract

The invention relates to a method for a processing soft soil foundation of an intertidal belt to form a construction working face. According to the method, slurry is compressed into soil strata through drilling holes in a grouting mode of compact grouting, and with the compact of soil body and the entry of the grout fluid, grout foam space around grout compressing points is formed; and meanwhile, since a radial uplift force is formed under the action of the entry of the grout fluid, local unheaval of the stratum is caused to increase the bearing force of the soil body, thus, the construction working surface or a functional site is formed. The method comprises the concrete construction steps as follows: A. drilling holes by using drilling equipment of a drilling machine, a water pump and a slurry stirrer; B. grouting; C. forming the grout foam space around the grout compressing points to cause the local unheaval of the stratum; and D. finally forming the construction working face. The construction technology can overcome the defects of insufficient bearing force of soft soil and larger sink in the intertidal belt and form a duricrust meeting the construction requirement on the surface of the soft soil in the intertidal belt and has low construction cost, convenient construction and less time.

Description

technical field

[0001] The invention relates to a construction technique for soft soil foundations of coastal tidal flats, in particular to a construction method for performing foundation treatment on soft soil in the intertidal zone of coastal tidal flats to form a construction work surface. Background technique

[0002] my country has a vast tidal flat area. Due to the large tidal range in the coastal waters, the tidal flat area is very flat and the intertidal zone is rich in resources. However, the environment in the intertidal zone is special, the corresponding technical level is limited, the land use value is low, and the development level is not yet high.

[0003] In recent years, land resources in coastal areas have become increasingly tense, and these coastal tidal flat resources have gradually become the target of development. Construction of various structures, such as wind farms, etc. began on tidal flats, that is, the intertidal zone with relatively low land us...
