Biconcave support-engaged water-stopping pile

Abstract

The invention discloses a biconcave support-engaged water-stopping pile. The biconcave support-engaged water-stopping pile comprises a pile body and a pile tip. The pile tip is provided with anchor bars and construction bars. The pile body comprises an upper pile section, a middle pile section and a lower pile section. The top of the upper pile section is provided with a pile cap and construction bars. The lower end of the upper pile section is provided with anchor bars. The upper end of the middle pile section is provided with threaded anchor holes. The lower end of the middle pile section is provided with anchor bars. The upper end of the lower pile section is provided with threaded anchor holes. The lower end of the lower pile section is provided with the pile tip. The two sides of the biconcave support-engaged water-stopping pile are respectively of a biconcave shape. The biconcave support-engaged water-stopping pile has the advantages that the bars are evenly distributed through a long-line pedestal in a single mode to tension stress overall, the two sides of the support-engaged water-stopping pile are respectively of the biconcave shape, and spiral stirrups are distributed on the two sides of the support-engaged water-stopping pile; as a result, production on the long-line pedestal can be carried out, labor and efforts are saved, the environment is protected, the productivity is high, product quality is good, the pile can form a tall and straight appearance beneficially, and the beauty and crack resistance are both good; the pile is suitable for stopping water in ports, wharfs and deep foundation pits, and resistant to corrosion and freezing-thawing.

Description

technical field [0001] The invention relates to the field of building construction, and mainly refers to a supporting and interlocking water-stop pile and a construction method thereof. Background technique [0002] In the field of engineering construction, with the continuous increase of high-rise and super high-rise building construction, in the field of industrial and civil construction projects and underground engineering excavation, for river estuaries, a large number of tidal flats, high groundwater levels, low strength, and relatively high compressibility in the area High, muddy silty cohesive soil, a large amount of miscellaneous fill humus soil and other geology are important issues for deep foundation pit excavation support and water stop. Foundation pit engineering is an ancient tradition. The construction method of sloping excavation and simple wooden pile enclosure is not suitable for the needs of contemporary building construction. Its construction progress is ...

Problems solved by technology

Drilled concrete occlusal piles are often used in current building excavation and support projects. Although this type of occlusal piles can meet the construction needs to a certain extent, the construction is difficult. If multiple drilling machines and a large number of different The caliber steel casing has a great limit on the pile diameter, and the production of the steel cage is more troublesome, and it is easy to deform and shift

Difficult to control during pouring of concrete

At the same time, it takes a long time for the concrete to set. After the occlusal pile is piled, it is easy to cause diameter shrinkage, grout leakage, exposed reinforcement, honeycomb, pockmarked surface, and it is difficult to ensure the thickness of the main reinforcement protective layer, which eventually leads to water leakage.

The verticality of the occlusal pile is also difficult to meet the design requirements

The reinforcement cage is easy to float when pouring concrete, seriously affecting the quality of the project

In the field of underground excavation under construction, the support and water stop of large foundation pits seriously affect the progress of the entire construction project due to the slow construction progress, so that the project cannot be completed as expected, causing great economic losses to the enterprise and affecting the economic benefits of the enterprise improvement
