Construction method of supporting double-concave occlusal water-stop pile

Abstract

The invention discloses a supporting and supporting double-concave occlusal water-stop pile. Including the pile body and the pile tip, the pile tip is provided with anchor reinforcement and structural reinforcement, the pile body includes the upper section pile, the middle section pile and the lower section pile, the pile top of the upper section pile is provided with pile cap and structural reinforcement, and the lower end of the upper section pile is provided with anchor reinforcement The upper end of the middle pile is provided with a threaded anchor hole, and the lower end of the middle pile is provided with an anchor bar; the upper end of the lower pile is provided with a threaded anchor hole, and the lower section of the lower pile is provided with a pile point; is biconcave. The beneficial effect of the present invention is: the supporting and interlocking water-stop pile adopts the long-line pedestal single-mode evenly distributed reinforcement, the overall tensile stress, the two sides of the supporting and interlocking water-stop pile are double-concave, and spiral stirrups are distributed. It can be used for long-line table production, saving labor, labor, environmental protection, high productivity, good product quality, and helps the product to form a tall and straight shape, with good aesthetics and crack resistance. It is suitable for water stop of ports, docks and deep foundation pits, anti-corrosion, anti-freezing and 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 ...

AI Technical Summary

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
