Occlusive pile construction method

Abstract

An occlusive pipe construction method comprises the following steps: constructing reinforced concrete piles in advance; constructing full-plain concrete piles by using a manual construction mode among piles after the reinforced concrete piles are solidified to a certain strength, wherein the full-plain concrete piles and the reinforced concrete piles are mutually occluded. According to the method, the reinforced concrete piles are constructed in advance, then the full-plain concrete piles are constructed manually without cutting the bodies of the reinforced concrete piles, and the constructing processes of the reinforced concrete piles and the full-plain concrete piles are relatively independent of each other and do not interact; in addition, strict requirements on time can be avoided as the construction of the reinforced concrete piles can be carried out without judging the forming states of the full-plain concrete piles first; the technology difficulty is greatly reduced, and the construction of manual hole shaping is free of strict shape requirements; construction manners can be flexibly changed when a rocky stratum is encountered during construction, the rocky stratum can be rapidly penetrated, the hole shaping quality can be controlled conveniently, and the occlusive effect is better than that of the traditional construction manner.

Description

【Technical field】 [0001] The invention relates to construction projects of buildings, civil engineering and infrastructure projects, in particular to a construction technology of occlusal piles. 【Background technique】 [0002] The occlusal pile refers to the foundation pit support formed by interlocking and arranging the pure concrete pile and the reinforced concrete pile. Arranged to form partial overlap and overlap, similar to the bite between piles, also known as occlusal piles. In the general industry field, the pure concrete pile is often referred to as the A pile for short, and the reinforced concrete pile is called the B pile for short. The pile is made of ultra-retarded concrete, which prolongs its solidification time and reserves the time for the construction of pile B. The construction technology requires that the construction of pile B must be completed before the initial setting of the concrete of pile A. [0003] Drilled occlusal piles are generally constructe...

Problems solved by technology

[0005] In view of the above situation, the present invention proposes a construction method for improving the construction process of occlusal piles. This construction method does not need to limit the construction time, and will not cause the problem of steel cage floating. The construction progress and time limit are relatively flexible, and can be configured according to equipment and manual configuration Arrangement, and from the perspective of construction effect alone, the degree of occlusion of the occlusal piles in this method is better, and there will be no problem of missing piles
