Problems solved by technology

[0002] During the construction of traditional bridge land pile foundations, usually after the original ground is leveled, the steel casing, drilling, lowering of the reinforcement cage, and concrete pouring work are started, and the pile heads are removed after the excavation of the cap is completed. The following problems exist. First, the pile foundation is easily damaged when the cap is excavated. Second, the pile head can only be removed after the cap is excavated. At this time, the strength of the concrete has been strengthened. It is difficult to remove the pile head and takes a long time. The civilized construction on site is poor, and the elevation difference between the pile top and the original ground is relatively large, resulting in more concrete overfilling

Abstract

The invention discloses an auxiliary structure for onshore pile foundation concrete pouring, the auxiliary structure is mounted at the top end of a steel casing to be subjected to concrete pouring, the auxiliary structure comprises a structure main body, the structure main body is circular and is formed by detachably splicing two arc-shaped plates, and the invention further provides a using method of the auxiliary structure. And a bearing platform cushion layer is constructed, a pile head is broken as soon as possible, concrete over-pouring can be controlled, and the effect of on-site civilized construction is improved.

Description

technical field [0001] The invention relates to the field of onshore pile foundation concrete pouring. More specifically, the present invention relates to an auxiliary structure for concrete pouring of onshore pile foundations and a method of using the same. Background technique [0002] In the construction of traditional bridge land pile foundations, the original ground is usually leveled, and then the steel casing, drilling, lowering the reinforcement cage, and concrete pouring are started, and the pile head is removed after the excavation of the cap is completed. There are the following problems: one is that the pile foundation is easily damaged when the cap is excavated; the other is that the pile head can only be broken after the excavation of the cap is completed. At this time, the strength of the concrete has been enhanced, and it is difficult to chisel the pile head, which takes a long time; three The civilized construction on site is poor, and the height difference...
