Problems solved by technology

[0002] The vehicle driving roads around the construction site may sometimes cross the basement wall and enter the building structure range. When there is a large post-construction settlement on the construction site, due to the uneven settlement of the foundation, there will be a sudden change in the settlement, which will cause driving bumps , even in the case of jumping

Embodiment Construction

[0009] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] Such as figure 1 The two ends of the board 1 are shown as resting on the pillow board 2 and the corbel 3 arranged on the outdoor wall of the basement respectively, and are hingedly connected by the connecting steel bars 5 between the corbel and the board, and the plain board 1 and the pillow board 2 are laid Concrete cushion 6, asphalt felt cushion 4 is placed between the board 1 and the pillow board 2 and the corbel 3, and the roadbed 7 and road surface 8 of the last lane are laid on the board 1 and the pillow board 2.

[0011] The manufacturing steps of the embodiment of the present invention are as follows.

[0012] 1. Construct the corbel 3 on the outdoor wall of the basement, and reserve the connecting steel bar 5 between the corbel and the board.

[0013] 2. Backfill the soil around the basement exterior walls or foundation...

Abstract

The invention relates to a transition slab structure for alleviating settlement mutation of a pavement of a car lane in the field of civil engineering structure construction. In order to solve the technical problem, the basic technical scheme adopted by the invention is as follows: a corbel is arranged on an exterior wall of a basement, one end of a transition slab is articulated and laid on the corbel, the other end of the transition slab is laid on one side of a sleeper slab, the laying length is 1 / 3-1 / 2 of the width of the sleeper slab, plain concrete cushion layers are arranged below the transition slab and the sleeper slab, a roadbed is arranged on the transition slab and the sleeper slab, and a pavement layer is arranged on the roadbed. Due to the measures of the structure construction, the stress is reasonable, the construction is convenient, and safety and comfort in driving on a rigid-flexible transition section of the roadbed can be improved.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a slab structure used to reduce sudden changes in road surface settlement when a driveway crosses a rigid-flexible transition section, such as a driveway that crosses a basement roof at the junction of a basement outer wall and a natural foundation. Background technique [0002] The vehicle driving roads around the construction site may sometimes cross the basement wall and enter the building structure range. When there is a large post-construction settlement on the construction site, due to the uneven settlement of the foundation, there will be a sudden change in the settlement, which will cause driving bumps , or even the case of jumping. Therefore, some measures need to be taken to meet the safety and comfort requirements of driving. Contents of the invention [0003] In order to enable vehicles to pass smoothly through the rigid-flexible transition zone of the subgrade suc...
