Embodiment Construction

[0026] In order to understand the technical solutions provided by the present invention more clearly, the present invention will be further described below in conjunction with specific examples.

[0027] A kind of circumcision method provided by the present invention breaks cast-in-situ pile technology, its construction steps;

[0028] The first step is construction preparation, and the work preparation inside the foundation pit is carried out;

[0029] The second step is to prepare the equipment, adjust the construction equipment properly, and prepare for operation;

[0030] The third step is to measure the elevation and position, mark the design elevation of the pile head, and prepare for the construction work;

[0031] The fourth step is ring cutting construction. Ring cutting equipment is used to cut the pile head at the design elevation, and at the same time, the concrete is chiseled on the cutting seam to expose the steel bars;

[0032] The fifth step is to tilt the ma...

Abstract

The invention discloses a process for breaking a cast-in-place pile through a ring cutting method. The process comprises the construction steps that firstly, construction preparation is made; secondly, machines and tools are prepared; thirdly, the elevation is measured, and locating is conducted; fourthly, ring cutting construction is conducted; fifthly, a main reinforcement is inclined toward theouter side; sixthly, iron wedges are driven in around a pile head; seventhly, the pile head is lifted away from a foundation pit by a crane; eighthly, an inclined reinforcement is recovered; and ninthly, a site is cleaned. According to the provided process for breaking the cast-in-place pile through the ring cutting method, the ring cutting depth is located effectively through novel ring cuttingequipment, a blade can be prevented from cutting the main reinforcement in the pile head, and meanwhile, the conditions that in a traditional process, an air compressor is adopted, and structural strength of the pile head is influenced are avoided.

Description

technical field [0001] The invention relates to a technique for breaking cast-in-situ piles by ring cutting. [0002] technical background [0003] Nowadays, the rapid economic development has brought about the large-scale development of municipal projects, and the municipal construction in the city needs to consider the original roads or construction projects, so it is necessary to consider the safety, efficiency and cost of construction. Many traditional construction techniques have been Unable to meet the existing construction status. [0004] There are two traditional techniques for removing cast-in-place piles. One is to use a gun head crusher to remove concrete from the top of the cast-in-place pile to the design elevation. This process removes the uneven height of the pile head, which cannot meet the design requirements and has low construction efficiency. , the construction period is long, and the long-term vibration operation will affect the overall durability of th...
