Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] Referring to Fig. 1, what shows therein is the three-dimensional schematic view of the continuous wall and other enclosure structures formed by a U-shaped concrete sheet pile A according to a specific embodiment of the present invention. The sheet pile is made of concrete and has a substantially U-shaped cross-section (see Figure 2-13 for the cross-sectional view), of course, as shown in Figure 2-13, the cross-sectional shape can also be described as the "ji"...

Abstract

The invention relates to an enclosing structure concrete slab pile in the building field, the slab pile is made of concrete and is provided with a cross section which is approximately in a U shape; the U-shaped cross section is provided with a bending section at the bottom of the U shape, and a first connection section and a second connection section which are arranged on both sides of the U shape; and the first connection section and the second section are respectively provided with a first connection part and a second connection part which are provided with matched shapes. The cross section of the U-shaped concrete slab pile provided by the invention is similar to an English letter U, and the pile has high anti-bending and high anti-shear performance in structural stress, and a certain bearing function. In addition, the connection parts on both sides are equivalent to a fastening plate, a gap can be left in the middle after connector splicing; and some paste material or other connection material can be filled into the gap in the middle, thereby ensuring the water sealing effect and the connection strength.

Description

technical field [0001] The invention relates to a soil retaining, slope protection and enclosure structure in the construction field, in particular to a U-shaped concrete sheet pile. Background technique [0002] Usually, due to the small distance between high-rise buildings, the excavation of foundation pits sometimes cannot be done by sloping excavation. For the stability of the foundation pit and the safety of the surrounding buildings, it is necessary to carry out retaining support for the foundation pit. In addition, soil retaining support structures are also required in the construction of river course regulation, high-grade highway construction, bridges, railway-highway interchanges and culverts. [0003] At present, the methods for foundation pit support mainly include bored piles and underground diaphragm walls. The shallow foundation pit foundation has higher economic cost. At present, some foundation pit foundations in China use steel sheet piles as foundation p...
