Embodiment

[0022] A crawler-type penetrating device for controlling the sinking of a cylindrical foundation, comprising a cylindrical foundation body 1, a crawler drive shaft 2, a ground-breaking crawler 3, prefabricated openings 4, crawler reinforcement ribs 5 and an external power device.

[0023] A number of prefabricated openings 4 are cut out on the outer side of the top cover of the cylindrical foundation body 1. The number and position of the openings should be consistent with the number of ground-breaking crawlers 3 arranged on the side wall. The crawler drive shaft is an area on the side wall of the cylindrical foundation body, where the inner wall and the outer wall are recessed inward, so that the ground-breaking crawler can be limited in the axial direction of the cylindrical foundation and can rotate along the crawler drive shaft to break the ground. The number of crawlers 3 can be calculated and designed according to the size of the cylindrical foundation body 1 and the phys...

Abstract

The invention discloses a crawler type injection device used for thick-wall concrete cylindrical foundation sinking. The crawler type injection device comprises a cylindrical foundation body, a soil breaking crawler and an external power device. Different types of strengthening ribs can be placed on the crawler. The crawler is controlled to conduct drive in a mud face so as to bring soil bodies near the cylinder wall out of the mud face, the soil resistance of the cylindrical foundation in the injection process is reduced, meanwhile, downward injection force is generated, and the cylindrical foundation is injected to reach the design depth under the effect of the injection force generated by the crawler and the gravity of the structure whole.

Description

technical field [0001] The invention belongs to the technical field of ocean engineering, and in particular relates to a crawler-type penetrating device for laying thick-walled concrete cylindrical foundations. Background technique [0002] As mankind enters the 21st century, the energy crisis has become increasingly prominent. As a renewable and clean energy, offshore wind energy has become a new direction to ease the global energy tension. As a new type of offshore platform foundation, the barrel foundation is essentially a circular plate foundation with skirt boards. Due to its advantages of reducing engineering volume, saving investment, shortening construction time, and being reusable, it is gradually being used in In the basic engineering of offshore wind power. [0003] The sinking process and related theories of steel thin-walled cylindrical foundations have been basically mature, but the cost of its own structure is too high to be widely promoted; thick-walled conc...
