Construction method of concrete pile

Abstract

The construction method of concrete pile includes the following steps: according to primarily-set pile legnth, sinking the guard cylinder to designed level, hammer ramming while filling interior of guard cylinder with filling material to form composite carrier of lower portion of pile end; when the filled quantity of the above-mentioned filling material is less than or equal to 30-50% of theoretical total filling quantity, completing construction of the above-mentioned composite carrier; when the filled quantity of the above-mentioned filling material is greater than or equal to to 30-50% of the theoretical total filling quantity, regulating the above-mentinoed primarily-set pile length, then further sinking guard cylinder, hammer ramming while filling guard cylinder with filling material, then filling hard concrete; ramming, inserting reinforced concrete pile body into the guard cylinder, taking out the above-mentioned guard cylinder, ramming said pile body and making it lightly combine with the above-mentioned composite carrier so as to complete said construction.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to the construction technology of piles in the foundation of buildings. Background technique [0002] In the past, people have proposed a construction technique for concrete piles, which includes a composite carrier and a concrete pile body, and the feature of this process is to effectively form a composite carrier, allowing the upper load to pass effectively through the pile and the composite carrier below the pile, and transfer To the bearing layer, thus greatly improving the bearing capacity of the pile. However, in the above process, the pile body is poured on site, so it is easy to shrink the diameter when the casing is raised, and the bottom of the pile is easy to disengage from the composite carrier. In addition, the difference between the amount of filler in the composite carrier and the actual geological conditions The relationship between piles has not been studied, resul...

However, in the above process, the pile body is poured on site, so it is easy to shrink the diameter when the casing is raised, and the bottom of the pile is easy to disengage from the composite carrier. In addition, the difference between the amount of filler in the composite carrier and the actual geological conditions The relationship between piles has not been studied, resulting in ground uplift and the mutual influence of adjacent piles
