A construction method in which a rectangular enclosure pile and an enclosure structure double as a main structure

Abstract

The invention discloses a rectangular enclosure pile, and a construction method using the rectangular enclosure pile as a main structure. The rectangular enclosure pile comprises a plurality of prefabricated rectangular piles which are arranged according to the set positions and equipped with grouting holes; a top pressing crown beam, a waist beam, and a partition wall which is built through coal has hollow bricks are fixed between adjacent piles; the horizontal supporting and reverse building combined method is utilized for constructing; the top pressing crown beam is horizontally fixed on the top part of the adjacent rectangular pile; the waist beam is horizontally fixed at a bracket of the adjacent rectangular frame; the partition wall is built in a space formed by the adjacent rectangular pile and the waist beam; when a foundation pit is excavated, a vertical support and a horizontal support of the enclosure structure are respectively used as a vertical part and a horizontal part of the main structure of a building, and therefore, the waste of temporary supporting structure can be avoided; meanwhile, the construction period is saved, and the sustainable development of the foundation pit work can be achieved.

Description

technical field [0001] The invention relates to a construction method in which a rectangular enclosure pile and an enclosure structure are also used as a main structure, and is especially suitable for the enclosure and excavation of foundation pits of large buildings in urban areas and the construction of underground main structures. Background technique [0002] At present, the surrounding protection piles of the foundation pit project are mostly poured on site, and the quality of the piles is difficult to guarantee. Broken piles and mud inclusions often occur and are not easy to repair; the concrete poured on site needs a period of strength increase, resulting in a waste of construction time; It is a temporary support structure. It is difficult to recycle after the excavation of the foundation pit, and it will be discarded after use, resulting in waste and soil pollution; The construction started after the construction, resulting in a great waste of materials and loss of c...

[0002] At present, the surrounding protection piles of the foundation pit project are mostly poured on site, and the quality of the piles is difficult to guarantee. Broken piles and mud inclusions often occur and are not easy to repair; the concrete poured on site needs a period of strength increase, resulting in a waste of construction time; It is a temporary support structure. It is difficult to recycle after the excavation of the foundation pit, and it will be discarded after use, resulting in waste and soil pollution; The construction started after the construction, resulting in a great waste of materials and loss of construction period, and the secondary stress and secondary deformation of the enclosure structure when the support is removed will have a further impact on the surrounding environment
