Background
The pile-plate retaining wall is a commonly used supporting and retaining structure in a geotechnical engineering filling side slope, and is particularly suitable for a high and large filling side slope. Compared with the rectangular cross-section slide-resistant pile, the circular cross-section slide-resistant pile has the characteristics of high construction speed, small potential safety hazard and the like, and along with the development of technical level and the requirement of project construction period, more and more circular cross-section slide-resistant piles replace the rectangular slide-resistant pile.
Because of the adoption of mechanical construction, the circular cross-section pile has no concrete retaining wall measure, in order to ensure the pile forming quality, the concrete pouring of the pile body below the ground is often required to be quickly finished after the pile hole is formed, the pile body above the ground cannot be used for supporting a mold, the broken pile is easily formed at the ground, the anti-slide pile has a weak surface, the engineering safety is not facilitated, the special reinforcement design aiming at the weak surface is required, and the construction measures are combined for realization;
on the other hand, the connection between the pile with the circular cross section above the ground and the retaining plate is more difficult than that between the pile with the rectangular cross section, but the connection between the pile with the circular cross section and the retaining plate is more difficult than that between the pile with the rectangular cross section, so that the requirements of reliable connection, shortening the construction period, facilitating construction, attractive appearance and the like with the retaining plate under the condition of meeting the stress requirement are needed, and the difficult problem to be solved urgently is solved. The retaining plate structure which is one of important components of the existing commonly used pile plate retaining plate is cast-in-place or prefabricated, a connection structure needs to be reserved on a pile body in consideration of cast-in-place, and a prefabrication method needs to take measures to ensure the connection reliability of the pile and the retaining plate. The common connection method of the anti-slide pile with the circular section and the cast-in-situ retaining plate is pre-embedded steel bars or embedded steel bars. The method of embedding the steel bars comprises the steps of perforating the embedded steel bars through a template, or drilling and implanting the steel bars on the anti-slide pile body, and then pouring the retaining plate. The retaining plate constructed by embedding the steel bars is easy to cause template perforation in the construction process, is difficult to reuse, leads to very high rejection rate and causes waste; the soil retaining plate constructed by the bar planting method is easy to damage or even break the bar body of the anti-slide pile, and brings hidden danger to engineering safety. Meanwhile, the cast-in-place retaining plate can backfill the soil body behind the pile plate retaining wall when the concrete strength reaches the rear side, so that the construction period is greatly prolonged. The prefabricated retaining plate is usually considered for convenient construction, is placed on the back side of the pile, is smaller than the contact surface of a round pile, is easy to generate stress concentration on the contact part of a plate body, is poor in stress, and is placed on the north side, so that the structure of the retaining wall of the whole pile plate is not attractive.
Therefore, the invention provides the pile-plate retaining wall structure suitable for filling the side slope and the construction method thereof based on the aspects of structural safety, construction period shortening, convenient construction, attractive appearance and the like.
