Embodiment Construction

[0035] The present invention will be further described below in conjunction with the embodiments, and the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other used embodiments obtained by persons of ordinary skill in the art without making creative efforts all belong to the protection scope of the present invention.

[0036] In conjunction with accompanying drawing, the construction method of the pile head anchor section of intercepting pile body of the present invention, comprises the steps:

[0037] (1) A reinforcement cage consisting of main reinforcement 1 and stirrup 2 is placed in the foundation pit of the pile foundation, and the upper end of main reinforcement 1 extends out of the stirrup 2 and is placed in the anchorage section 01 of the pile head;

[0038] (2) Set the protection tube 3 on the main reinforcement 1 extending out of the stirrup 2, that is to say, put ...

Abstract

The invention belongs to the technical field of rigid piles, discloses a construction method for cutting a pile head anchorage section of a pile body, and aims at solving the problems of high cost andlarge noise pollution existing in the existing mode for cutting a pile head anchorage section of a pile body. A rotary jetting reserved hole is formed in concrete of the pile head anchorage section,a main reinforcement of a pile head reinforcement cage section of the pile head anchorage section is sleeved with a protection pipe, after concrete pouring is completed, a high-pressure rotary jettingnozzle of a rotary jetting machine jets water to cut off concrete between the pile head anchorage section and a body of the pile body, and thus the pile head anchorage section is cut. Compared with aknocking breaking mode of the prior art, the construction method has the advantages that the construction period can be shortened substantially, construction cost can be lowered, and meanwhile, noisepollution of cutting of a pile head is lowered.

Description

technical field [0001] The invention belongs to the technical field of rigid piles, and in particular relates to a construction method for intercepting a pile head anchorage section of a pile body. Background technique [0002] The rigid pile is used to support the pile foundation bearing platform, and the top position of the rigid pile is in contact with the bottom surface of the pile foundation bearing platform so as to bear the building. [0003] The construction process in the prior art is: first pour the pile body to the soil surface, then excavate the foundation pit, and then pour the pile foundation bearing platform on the surface of the foundation pit. The upper pile body (that is, the anchorage section of the pile head) needs to be destructively cut. In the prior art, the anchorage section of the pile head is generally cut by manual crushing (concrete is broken by knocking), but after the concrete is solidified, the anchorage section of the pile head is intercepted....
