Embodiment Construction

[0042] The following is attached Figure 1-6 The present invention is described in further detail.

[0043] A connection structure of prefabricated sheet piles and its construction method disclosed in the embodiment of the application, such as figure 1 As shown, it includes several sheet pile units, and several sheet pile units are sequentially spliced ​​along the circumference of the foundation pit to form the foundation pit enclosure 1. The plate body 2 at the corner of the foundation pit enclosure 1 is a right-angle plate, and the foundation pit enclosure 1 is surrounded by a cuboid , the pile foundation unit includes two boards 2 vertically connected up and down and a connection assembly 3 for connecting the two boards 2 .

[0044] Such as figure 2 As shown, an insert block 4 is integrally formed along the vertical direction in the middle part of one end face of the plate body 2, and the middle part of the end face of the plate body 2 relative to the insert block 4 is p...

Abstract

The invention discloses a connection structure of prefabricated sheet piles and a construction method thereof, and relates to the technical field of sheet pile construction. The connection structure comprises a plurality of sheet pile units which are sequentially spliced along the periphery of a foundation pit, each sheet pile unit comprises two sheet bodies which are adjacently arranged up and down and a connecting assembly used for connecting the two sheet bodies, the upper sheet bodies and the lower sheet bodies are connected through welding, each connecting assembly comprises two connecting plates arranged on the two opposite side faces of each sheet body correspondingly, a connecting piece used for locking the two connecting plates and an anchoring piece stretching into the soil layer, and the two connecting plates clamp the welding position between the two sheet bodies on the corresponding sheet pile unit. The connection structure has the effect that the construction period can be shortened while the side wall of the foundation pit is reliably supported by the sheet pile units.

Description

technical field [0001] The invention relates to the technical field of sheet pile construction, in particular to a connection structure of prefabricated sheet piles and a construction method thereof. Background technique [0002] The supporting structure of the foundation pit engineering generally adopts row piles or continuous walls, and the row piles are generally spliced ​​with prefabricated sheet piles to form the foundation pit enclosure. Sheet piles cannot achieve effective support, and bored piles are usually used instead of prefabricated sheet piles. [0003] However, the bored cast-in-place pile needs to insert a reinforcement cage into the soil layer and pour concrete to form the cast-in-situ pile. The concrete setting and hardening process takes a long time, prolonging the construction period. Contents of the invention [0004] In order to achieve the effect of shortening the construction period while the sheet pile unit reliably supports the side wall of the f...
