Description

Improved generation buttress formula barricade of can encorbelmenting

Technical Field

The utility model belongs to the technical field of choose counterfort formula barricade, concretely relates to improved generation can encorbelment counterfort formula barricade.

Background

The buttress retaining wall (buttress retaining wall) is a retaining wall formed by adding buttresses at certain intervals along the vertical wall of a cantilever retaining wall and connecting the vertical wall with a heel plate. The counterfort retaining wall is a reinforced concrete thin-wall retaining wall, and has the main characteristics of simple structure, convenient construction, smaller wall body section and light self weight, can better play the strength performance of materials, and can adapt to a foundation with lower bearing capacity; it is suitable for use in areas lacking stone material and earthquake. The embankment is generally stabilized by adopting the embankment on a higher filling road section so as to reduce the earth and stone engineering quantity and the occupied area. The counterfort type retaining wall has smaller section size, the gravity of the soil body on the heel plate can effectively resist overturning and sliding, the vertical plate and the counterfort jointly bear bending moment and shearing force generated by soil pressure, and the stress is good relative to the cantilever type retaining wall. The method is suitable for filling side slopes with the height of 6-12 m, and can effectively prevent the filling side slopes from sliding.

The counterfort retaining wall is one of road shoulder retaining walls, a prefabricated retaining wall plate is welded on a steel plate pre-embedded in foundation concrete, and then compared with retaining walls of other forms, the counterfort retaining wall has the advantages of saving occupied space, shortening construction period, beautifying urban environment, being easy to construct and the like, and is a commonly used retaining wall form in an approach of an urban highway engineering overpass.

The counterfort retaining wall is composed of a wall panel (vertical wall), a toe board, a heel board and counterforts (counterfort). The supporting ribs connect the vertical wall with the wall heel plate and play a role in stiffening, so that the stress condition of the vertical wall and the wall heel plate is improved, the rigidity and the integrity of the structure are improved, and the deformation of the vertical wall is reduced.

Buttress type retaining walls are also often used in conjunction with pile foundations during construction to become pile foundation joist retaining walls or stacked retaining walls. In the areas limited by red lines, buildings and the like, the side walls of the areas are difficult to pour due to the fact that the areas are not provided with working surfaces during construction. In order to solve the problem, an overhanging plate is usually added at the top, but considering factors such as the eccentricity of the retaining wall, stress and the like, the overhanging length is generally about 1 m. If the overhang length exceeds this length, the control of the reinforcing bars of the side walls and the deformation of the entire support system is very disadvantageous.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve board length overlength of encorbelmenting and the unfavorable problem of deformation control of the arrangement of reinforcement and the whole system of strutting of side wall that arouses, and provide an improved generation and can encorbelment counterfort formula barricade.

For solving the technical problem, the utility model discloses the technical scheme who adopts is:

the utility model provides an improved generation buttress formula barricade that can encorbelment, includes buttress formula barricade bottom plate, buttress formula barricade floor and buttress formula barricade side wall, its characterized in that, a plurality of stands have been pour on the buttress formula barricade bottom plate, the crossbeam has been pour on the stand, the one end and the stand of crossbeam are connected, the other end and the buttress formula barricade side wall of crossbeam are connected, be connected with the board of encorbelmenting between buttress formula barricade side wall and the current building.

In some embodiments, the columns are disposed between adjacent buttress wall ribs.

In some embodiments, the positions of the upright and the pile foundation correspond to each other.

In some embodiments, the steel bars of the upright posts and the steel bars of the counterfort retaining wall bottom plate are connected together and then poured together.

Compared with the prior art, the utility model discloses following beneficial effect has:

compared with the traditional cantilever scheme, the improved cantilever type retaining wall can increase the length of the cantilever plate, so that the whole cantilever type retaining wall can share the overturning force and the moment generated by the cantilever plate, and a bent component is converted into a component mainly based on tension and compression; and (4) forming a frame system for the pile foundation joist retaining wall finally, and transmitting force to the pile foundation and the foundation. Therefore, after the cantilever plate exceeds 1m, the deformation of the whole supporting system can be still effectively controlled.
