An I-shaped enclosure pile and a construction method with an enclosure structure serving as a main structure

Abstract

The invention discloses a construction method of an H-shaped enclosure pile and an enclosure structure as a main structure. The construction method comprises the following steps of arranging a plurality of H-shaped piles, wherein the H-shaped piles are arranged at the preset positions, are prefabricated and are provided with corbels; fixing a pressure top crown beam, a waist beam and a prefabricated ribbed prestressed plate between the adjacent piles, and combining the horizontal support reverse construction process; casting the pressure top crown beam at the top parts of the adjacent H-shaped piles, casting the waist pile on the corbels of the adjacent H-shaped piles, fixing the prefabricated ribbed prestressed plate between the adjacent H-shaped piles, and enabling the pressure top crown beam and the waist beam to control the deformation of a foundation pit through the horizontal support. The construction method has the advantages that after the foundation pit is evacuated, the vertical support and the horizontal support of the enclosure structure are also used as a vertical member and a horizontal member of the building main structure, so the waste of temporary support structure is avoided, the construction period is shortened, and the sustained development of the foundation pit engineering is favorably realized.

Description

technical field [0001] The invention relates to a construction method of an I-shaped retaining pile and the retaining structure serving as the main structure, and is especially suitable for the excavation of the retaining of large deep foundation pits in urban areas and the construction of the underground part of the main body of the building. Background technique [0002] At present, the enclosure structure of foundation pit engineering mostly adopts on-site hole formation, mud wall protection and underwater pouring, which takes a long time to maintain, and the quality of piles is difficult to guarantee, and problems such as broken piles and mud are not easy to repair; the enclosure structure is mostly temporary The support is discarded after use, and the main structure of the building and the enclosure structure cannot be combined into one, resulting in waste of materials and loss of construction period, and a large number of temporary support structures such as reinforced ...

[0002] At present, the enclosure structure of foundation pit engineering mostly adopts on-site hole formation, mud wall protection and underwater pouring, which takes a long time to maintain, and the quality of piles is difficult to guarantee, and problems such as broken piles and mud are not easy to repair; the enclosure structure is mostly temporary The support is discarded after use, and the main structure of the building and the enclosure structure cannot be combined into one, resulting in waste of materials and loss of construction period, and a large number of temporary support structures such as reinforced concrete are buried underground to pollute the surrounding soil; the enclosure structure adopts The horizontal support must be dismantled after the excavation is completed and cannot be used as a part of the main structure, which also causes 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 further affect the surrounding environment
