Problems solved by technology

[0005] However, when the Larsen steel sheet piles are inserted into the ground, it cannot be guaranteed that several Larsen steel sheet piles are arranged in a straight line, so that the position of some Larsen steel sheet piles is offset, so that the offset Larsen steel sheet piles cannot abut against the corresponding steel pipe or Section steel, resulting in the steel pipe or section steel not being able to normally support the offset steel sheet pile, which is prone to safety hazards

Embodiment 1

[0032] Embodiment 1: A support structure using Larsen steel sheet piles, such as figure 1 and figure 2 As shown, it includes several Larsen steel sheet piles 1 inserted on the ground, and several Larsen steel sheet piles 1 enclose a rectangular foundation pit enclosure 2, and the inner cavity of the foundation pit enclosure 2 is the foundation pit. And the four side walls of the foundation pit enclosure 2 are all poured with concrete beams 3, the concrete beams 3 are arranged horizontally, and the four concrete beams 3 are integrally formed, such as image 3 As shown, the side wall of the Larsen steel sheet pile 1 is also welded with a connecting piece 4, which is square and ring-shaped and made of round steel, and the connecting piece 4 is vertically arranged, and several connecting pieces 4 are located at the same horizontal position and It is poured into the concrete beams 3, wherein several groups of supporting components corresponding to the two concrete beams 3 are arr...

Embodiment 2

[0036]Embodiment 2: A construction method for foundation pit support, for the construction method of Embodiment 1: the construction method includes the following steps, step S1: first press several Larsen steel sheet piles 1 into the ground by a pile driver, and the pile driver It can be a vibrating pile hammer, which is used to press the Larsen steel sheet pile 1 into the ground, and ensure that several Larsen steel sheet piles 1 enclose a rectangular foundation pit enclosure 2, and make it close to the bottom surface of the Larsen steel sheet pile 1 Keep it flat; Step S2: Excavate the surface soil on the inner surface of the foundation pit enclosure 2, so that the upper part of the Larsen steel sheet pile 1 is exposed; Step S3: Weld the connecting piece 4 on the side wall of the Larsen steel sheet pile 1, and then connect the connecting piece 4 Weld diagonal stay rods 10 between Larsen steel sheet piles 1, and make all connecting pieces 4 at the same horizontal position, then...

Abstract

The invention discloses a supporting structure using Larsen steel sheet piles and a construction method thereof and is intended to ensure supporting for a foundation pit enclosure and ensure that allLarsen steel sheet piles not neatly arranged are supported. The supporting structure according to the technical scheme is characterized by comprising a plurality of Larsen steel sheet piles inserted onto a ground, the Larsen steel sheet piles enclose a foundation pit enclosure, the foundation pit enclosure is rectangular, and a concrete beam is cast to each of four inner walls of the foundation pit enclosure and is horizontally arranged, wherein a plurality of groups of support components for supporting two symmetric concrete beams are arranged between the two concrete beams; a connector connected with the corresponding concrete beam is welded to the sidewall of the corresponding Larsen steel sheet pile facing the concrete beam; the connectors are cast to the concrete beams. The supportingstructure using Larsen steel sheet piles and the construction method thereof have the advantages that the foundation pit enclosure can be supported well and it can be ensured that the Larsen steel sheet piles not neatly arranged are all supported well.

Description

technical field [0001] The invention relates to the field of construction engineering, more specifically, it relates to a support structure using Larsen steel sheet piles and a construction method thereof. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures adopted for the side wall of the foundation pit and the surrounding environment. [0003] The industry standard of the People's Republic of China "Technical Regulations for Building Foundation Pit Support" JGJ120-2012 defines the foundation pit support as follows: in order to protect the safety of the underground main structure construction and the surrounding environment of the foundation pit, temporary supports, Measures for reinforcement, protection and groundwater control. [0004] Many existing foundation pit supports use Larsen steel she...
