Description

Stake sheet wall

Technical Field

The utility model relates to the technical field of constructional engineering, in particular to a pile plate wall.

Background

The sheet pile wall is a retaining structure formed by upright strip-shaped members for resisting lateral soil pressure, and consists of two parts of piles and retaining walls between piles, wherein the retaining wall is maintained to be stable through the anchoring acting force and passive upper resistance (the constraint counter force of surrounding rocks to the supporting structure caused by the deformation of the supporting structure in opposite surrounding rock directions) of the anchoring section of the deep buried part of the pile. The pile plate wall is suitable for the condition that the soil pressure is large and the wall height exceeds the limit of a common retaining wall, and the defect of foundation strength can be compensated by the burial depth of the pile.

The pile plate wall mainly adopts a reinforced concrete structure, and the pile plate wall construction can be performed in a form of prior prefabrication and on-site assembly, or in a cast-in-situ mode; when the pile plate wall is constructed in a cast-in-situ mode, in order to connect the retaining wall with piles at two ends, the existing mode is to support the retaining wall template and pour retaining wall concrete after the piles are constructed, the retaining wall concrete and the piles form an integral structure after solidification, and the pile plate wall constructed in the construction mode is limited in the performance of resisting the soil pressure and is easy to damage due to the effect of the soil pressure. The other construction mode is that after the construction of the pile is finished, holes are drilled on the side face of the pile, connecting ribs are implanted into the holes, retaining walls are poured after the connecting ribs are implanted, the pile and the retaining walls are connected into an integral structure through the connecting ribs, and the mode increases the connection stability of the pile and the retaining walls; however, when the pile is perforated, the depth of the hole is too shallow to provide stable anchoring force, and too deep of the hole can damage the pile structure, affect the bearing capacity of the pile and affect the performance of the pile slab wall; in addition, in the construction process, the implanted connecting ribs are unstable to connect and easily fall off from the pile holes, so that the integrity and stability of the connection between the pile and the retaining wall are affected.
