Problems solved by technology
However, there is no precedent for this construction method in my country's hydropower and water conservancy projects. The bottleneck of these construction technologies has plagued the construction industry for many years, making it difficult to popularize reinforced concrete structures or hard rocks.

Embodiment 1
[0074] 1. Characteristics of construction method
[0075] 1.1 The rapid hole-forming method in reinforced concrete structure or hard monolithic bedrock effectively solves the problem of rapid hole-forming construction on reinforced concrete structures without blasting and without destroying the structure, thus ensuring the quality and safety requirements.
[0076] 1.2 Effectively solve the problem that the groundwater level is high, the water seepage in the hole is large, and the top surface elevation of the pile foundation is relatively shallow under the water. There is no need for drainage and anti-seepage treatment to form holes on reinforced concrete structures.
[0077] 1.3 It solves the problem of not using mud when forming holes, which effectively protects the balance of the ecological environment and saves the construction site.
[0078] 1.4 The method of rapid hole formation in reinforced concrete structure or hard monolithic bedrock is adopted. The requirements for ...

The invention discloses a construction method for forming a pile in a reinforced concrete structure or a hard integral bedrock, and belongs to the technical field of water conservancy and hydropower engineering construction processes. The method is characterized in that safety and fastness are achieved, blasting is not needed, and the file can be formed in the reinforced concrete structure or thehard integral bedrock without damaging the structure. The construction method comprises the following steps of a, drilling and slag discharging work of a pile hole is completed in a one-time subsection mode on the reinforced concrete structure or the hard integral bedrock through a common rotary drilling machine cooperated with a self-made drilling tool, b, manufacturing a reinforcement cage and arranging a detection tube in the qualified reinforcement cage, c, arranging the reinforcement cage into the pile hole with qualified drilling, and d, pouring concrete in the pile hole with the qualified reinforcement cage arrangement, carrying out piling, and completing the construction work of forming the pile in the reinforced concrete structure or the hard integral bedrock, wherein the step a and the step b are correspondingly performed on different places at the same time.
Description
technical field [0001] The invention relates to a construction method, in particular to a construction method for forming piles in a reinforced concrete structure or a hard integral bedrock, and belongs to the technical field of construction technology of water conservancy and hydropower projects. Background technique [0002] In hydropower and water conservancy projects, the construction method of quickly forming holes in reinforced concrete structures or hard monolithic bedrock is used as an engineering measure for foundation treatment, and has been applied to varying degrees in highways, railways, mines, housing construction and other projects in my country. At present, in addition to being used for foundation projects with general soil layers and soft rocks, it is also used as a support for load-bearing foundations or retaining walls in the construction of some high-rise buildings, bridges, railways, mines, and highways. In hydropower and water conservancy projects, it i...
