Description
Technical Field
The utility model relates to a keep off structure suitable for mountain area railway, highway fill district, in particular to weighing apparatus formula retaining wall who contains the reinforcing bar structure.
Background
The weight-balanced retaining wall is developed by the gravity retaining wall, and the wall body is formed by plain concrete pouring, and the wall body is kept stable by utilizing the weight of soil filled on the upper wall weight-balanced platform and the self weight of the wall body. Compared with a gravity retaining wall, the weight retaining wall has the advantages that the height of the weight retaining wall can be higher, the self-stability is better, the weight retaining wall is a retaining wall form which is widely applied to mountainous railway in China, and the weight retaining wall is popularized and applied in other industries such as roads.
The balance weight type retaining wall has the characteristics of simple structure form, abundant stone material sources, convenience in local material acquisition and the like of the common gravity type retaining wall, and the particularity is also increased due to the addition of the balance weight table. The joint of the upper wall and the lower wall has a section mutation, and the drainage hole is arranged to form a weak point of the whole wall, so that the shear failure is easy to occur in service in actual engineering. The existence of the weak point limits the application range of the balance weight retaining wall, particularly in earthquake areas and areas with high soil pressure or high possibility of large dynamic load and other complex conditions.
In order to solve the problem, the following two technical measures are usually adopted in the current practical engineering, firstly, vertical dowel bars are arranged at the joint of the upper wall and the lower wall of the balance weight type retaining wall, and the dowel bars can play a certain shearing resisting role, so that the shearing resisting capability of the weak points at the joint of the balance weight type upper wall and the lower wall is enhanced to a certain degree, but the insertion and the control are not easy to construct, and the dowel bars are structural measures without forming a stirrup frame, so that the shearing resisting effect of the dowel bars is limited; and secondly, the lacing bars are embedded in the upper wall of the balance weight type retaining wall, the effect of increasing the safety of the section of the upper wall is realized by reducing the soil pressure borne by the balance weight type upper wall, the integral stability of the retaining wall is improved, but the problems that the reinforced soil is inconvenient to roll and construct, the reinforcing materials are easy to age and the like exist, the weak points at the joint of the balance weight type upper wall and the balance weight type lower wall still exist, and the lacing bars are not suitable for the conditions of complex stress and easy failure of the lacing bars.
Therefore, there is a need for further improvement and optimization of the existing balance weight type retaining wall, and a balance weight type retaining wall capable of effectively improving the shear resistance of the weak sections of the upper wall body and the lower wall body of the balance weight type retaining wall is developed.
