Background

The expansive rock soil is a special rock soil with the characteristics of repeated expansion and contraction, lower strength, more cracks and the like, has poor engineering properties, has extremely large change of mechanical properties after meeting water, and is very easy to cause disasters such as collapse, landslide and the like. According to the design specification of railway subgrade, the design of the expansive soil cutting slope follows the principle of combining the slope slowing rate, the wide platform, the reinforced slope toe and the proper slope protection. Usually, the toe reinforcement retaining structure is a rectangular sheet pile wall or a gravity retaining wall.

The gravity type retaining wall has no pre-reinforcing effect, a foundation pit needs to be excavated during construction, a temporary side slope is easy to collapse, and groove jumping excavation or temporary reinforcing measures need to be taken. The pile plate wall has a pre-reinforcing effect, generally needs to be constructed in a manual hole digging mode, and is low in construction efficiency and high in safety risk.

In order to solve the technical problem, the utility model discloses a technical scheme is: provides a row pile retaining wall with a permanent retaining structure, which comprises bored piles, wherein a crown beam is arranged at the top of each bored pile, a reverse filter layer is arranged between every two adjacent bored piles, concrete panels are vertically arranged on the outer sides of the bored piles and the reverse filter layer, concrete cushions are horizontally arranged at the bottoms of the reverse filter layer and the concrete panels, a reinforcing mesh is vertically arranged in the concrete panels, the reinforcing mesh is positioned in the concrete panels, the free end of the bottom of the reinforcing mesh is inserted into the concrete cushions, and the top of the reinforcing mesh extends into the crown beam, and the concrete cushion layer, the concrete panel and the crown beam are provided with expansion joints every 10m or so and located between the cast-in-situ bored piles. Reinforcing bar net piece from top to bottom the equidistance is provided with a plurality of strengthening ribs, and each implantation reinforcing bar all is located the strengthening rib by. The inverted filter layer is 0.5m thick sand filled with pebbles. The filling material in the expansion joint is asphalt reinforcement, and the filling of the asphalt reinforcement is at least 0.2 m. The filling material in the expansion joint is an asphalt wood board, and the filling amount of the asphalt wood board is at least 0.2 m.

In the using process, after a user excavates a pile top platform, firstly, a conventional machine is adopted to construct a bored pile, then, a soil body in front of the pile is excavated, the bored pile can play a pre-reinforcement role, the safety risk during construction is reduced, the construction efficiency is improved, and a cutting slope is excavated on one side of the pile top platform; a bagged sand-pebble inverted filter layer with the thickness of 0.5m arranged between the cast-in-situ bored piles can effectively buffer the expansion and contraction deformation of expansive soil; the steel bar net piece in the concrete panel is connected with the cast-in-situ bored pile through the embedded steel bars of the pile body, so that the cast-in-situ bored pile can be erected and cast, the appearance is ensured to be neat, and the integrity is good; drainage holes are formed in concrete among the bored piles to ensure smooth drainage; the expansion joint and the water drainage hole are arranged in a staggered mode, and good using effect is guaranteed.

The utility model has the advantages and positive effects that: by adopting the technical scheme, a user can use conventional equipment to carry out mechanical construction, and the method has the characteristics of safety, reliability, high construction efficiency and low construction risk and has popularization and application values; just the utility model discloses simple structure, easy maintenance, the processing cost is low.
