Supporting and protecting double-convex and single-concave occluded water stopping pile

Abstract

The invention discloses a supporting and protecting double-convex and single-concave occluded water stopping pile which comprises a pile body and a pile tip, wherein the pile tip is provided with an anchor rib and a construction rib; the pile body comprises an upper section pile, a middle section pile and a lower section pile; a steel pile cap and a construction rib are arranged on the pile top of the upper section pile; an anchor rib is arranged at the lower end of the upper section pile; a threaded anchor hole is formed in the upper end of the middle section pile; an anchor rib is arranged at the lower end of the middle section pile; a threaded anchor hole is formed in the upper end of the lower section pile; a pile tip is arranged at the lower section of the lower section pile; three surfaces of the double-convex and single-concave occluded water stopping pile are of double-convex and single-concave shapes. The supporting and protecting double-convex and single-concave occluded water stopping pile has the beneficial effects that by the adoption of long-line pedestal single die for uniform rib distribution, the whole supporting and protecting occluded water stopping pile tensions the stress; the three surfaces of the double-convex and single-concave occluded water stopping pile are of the double-convex and single-concave shapes, and helical stirrups are distributed; therefore long-line table production can be realized, the time and the labor are saved, the environment friendliness is realized, the productivity is high, and the product quality is high; a tall and straight appearance of the product can be formed; the attractiveness and the crack resistance are high; the supporting and protecting double-convex and single-concave occluded water stopping pile is suitable for water stopping at ports and piers and in deep foundation pits, and is corrosion-resistant and freeze thawing-resistant.

Description

technical field [0001] The invention relates to the field of building construction, and mainly refers to an 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 slow, poor in ...

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
