High-efficiency honeycomb type pile head breaking construction process

Abstract

The invention discloses a high-efficiency honeycomb type pile head breaking construction process. The construction process comprises the steps that in the process of processing and manufacturing a reinforcement cage, each main reinforcement and each sounding pipe of the reinforcement cage are each sleeved with an isolation sleeve; after completion of processing of the reinforcement cage, the reinforcement cage is put into a drill hole, concrete is poured into the drill hole to form a cast-in-place pile; a pit is excavated in seven days after pouring, steel wedge blocks are symmetrically and horizontally inserted and driven in the annular tangent positions until a pile head is separated from a pile body, and then the pile head is removed. According to the high-efficiency honeycomb type pilehead breaking construction process, the main reinforcements are sleeved with the isolation sleeves, and damage to the main reinforcements in the treatment process of the pile head is effectively avoided. Moreover, the operating process is simple, and the construction efficiency is high. Input of construction equipment is reduced. Construction noise is greatly lowered. Dust flying is prevented. The construction environment is improved. Health of construction staff is effectively protected.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a high-efficiency honeycomb method pile head breaking construction technology. Background technique [0002] Due to the development of industry, the growth of population, and the continuous increase of high-rise buildings, the foundation conditions of many cities are relatively poor, and there are soft soils with a large thickness or medium-strength open soil layers underground, which cannot directly withstand the radiation from high-rise buildings. load. So just dig a hole in the soil, and pour reinforced concrete into the hole to form a pile. Until the early 1940s, with the emergence of high-power drilling machines, bored piles were first used in the United States. With the rapid development of science and technology, the design and construction level of bored piles in highway construction have also been greatly developed. Bored piles have the charact...
