Embodiment Construction

[0021] In order to illustrate the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0022] see figure 1 , figure 1 Shown is a schematic cross-sectional structure diagram of the force transmission device for the bottom plate of the shallow pit and the support of the deep pit according to the present invention. The force transmission device 1 is arranged between the bottom plate of the shallow pit 2 and the support 3 of the deep pit. Specifically, the shallow pit floor 2 includes a first bottom plate 21 disposed on the shallow pit floor surface 20 of the shallow pit floor 2 , and a first bottom plate 21 disposed on the shallow pit floor 2 different from the shallow pit floor surface 20 . The second bottom plate 22 on one side; the force transmission device 1 is arranged on the lower side of the shallow pit bottom plate ...

Abstract

The invention relates to a force-transferring device for a shallow pit base plate and a deep pit strut. The force-transferring device is arranged between the shallow pit base plate and the deep pit strut and is located on the lower side of the shallow pit base plate; the force-transferring device is provided with an additional declining section, a base plate cushion layer and a base plate additional element; the additional declining section has a certain preset gradient; the base plate cushion layer is formed at the bottom of the additional declining section; the base plate additional element is formed on an upper surface of the additional declining section; and the preset gradient is formed by a horizontal section and a slope section of the additional declining section. According to the invention, the force-transferring device is arranged between the shallow pit base plate and the deep pit strut, so that the construction is synchronously performed in the construction stage of the shallow pit base plate, the effective force transfer is formed by the shallow pit base plate and the deep pit strut, the subsequent structure joint is conveniently finished without chiseling and removing a top beam ring embosoming the deep pit, and the construction difficulty of the subsequent structure joint is relieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a force transmission device and a construction method for a shallow pit bottom plate and a deep pit support. Background technique [0002] At present, with the development of building construction in the direction of fast pace and high complexity, in the construction of foundation pits, pit-in-pit and group-pit construction widely appear. However, due to the generally tight construction period, it is obvious that the current construction period cannot meet the needs of the current construction period according to the usual construction process. [0003] Therefore, in view of the problems existing in the existing technology, the designer of this case relied on years of experience in this industry to actively research and improve, so he invented the force transmission device and construction method for the shallow pit floor and deep pit support.
