Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a structure for preventing uneven settlement. Background Art
[0002] Due to the inconsistent rigidity of the junction between the underground garage roof and the non-underground garage area, during the use of the basement, the non-underground garage area is prone to high settlement due to pressure, resulting in uneven settlement, which affects the later ground paving effect. In the current construction technology, more attention is paid to the waterproofing and drainage engineering of the roof to solve the problems of garage leakage and seepage, but insufficient attention is paid to the uneven settlement between the basement roof and the non-underground area. Once settlement occurs, the maintenance cost is high. Utility Model Content
[0003] The utility model provides an anti-uneven settlement structure, which prevents uneven settlement between the basement top plate and the non-basement area by arranging a reinforced concrete layer spanning the basement top plate and the non-basement area.

[0005] A structure for preventing uneven settlement comprises a horizontally arranged reinforced concrete layer and a ridge wall vertically arranged below the reinforced concrete layer, wherein one side of the reinforced concrete layer is located above a basement roof, and the other side is located above a non-basement area, a first filling layer is provided between the reinforced concrete layer and the basement roof, and a second filling layer is provided between the reinforced concrete layer and the non-basement ground.
[0006] The reinforced concrete layer has high strength and is not easy to deform. It is set across the basement roof area and the non-basement area, effectively preventing uneven settlement caused by the difference between the rigid structure of the basement roof and the flexible structure of the non-basement area. The ridge wall set above the basement roof provides a fulcrum for the reinforced concrete layer.
[0007] Furthermore, a waterproof layer is provided on the top surface of the basement roof, and the ridge wall is vertically fixed on the waterproof layer.
[0008] Furthermore, a drainage layer is provided on the waterproof layer, and a side wall of one side of the drainage layer is in contact with the ridge wall.
[0009] The setting of waterproof layer and drainage layer can prevent water accumulation above the basement roof, and at the same time prevent the foundation from being soaked in water for a long time, affecting the bearing capacity of the foundation.
[0010] Furthermore, the filling layer 1 includes a 37 soil layer 1 and a backfill soil layer 1, and the 37 soil layer 1 is located below the backfill soil layer 1.
[0011] The 37 soil layer has high strength and can provide support for the backfill soil layer and the reinforced concrete layer, improve the rigidity of the filling layer, increase the bearing weight, and ensure stability during use.
[0012] Furthermore, the filling layer 2 includes, from top to bottom, a backfill soil layer 2, a 37 soil layer 2 and a rubble stone cushion layer, and the backfill soil layer 2 is flush with the top surface of the backfill soil layer 1 and has the same thickness.
[0013] The rubble stone cushion layer can transfer the load to the foundation evenly, making it less likely to collapse; the 37 soil layer 2 and the rubble stone cushion layer together provide support for the backfill soil layer 2 and the reinforced concrete layer, increasing the bearing weight and ensuring stability during use.
[0014] Furthermore, the drainage layer is made of crushed stone ceramsite.
[0015] Furthermore, a floor is provided on the backfill soil layer 1 and the backfill soil layer 2, and the top surface of the floor is flush with the top surface of the reinforced concrete layer. BRIEF DESCRIPTION OF THE DRAWINGS
