Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a drainage structure for a post-cast zone of a basement. Background Art

[0002] Post-cast strips are used in construction to prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement. When building a basement, the top slab of the basement is also equipped with post-cast strips. Deformation joints are left during the construction of the basement top slab. After the main structure is completed and the concrete solidifies, the post-cast strips are sealed with concrete to form a continuous whole.

[0003] Since the concrete in the post-cast joint is poured subsequently, a reasonable construction process is required to make the post-cast joint concrete and the original concrete form a continuous whole. If it is not handled properly during construction, water leakage in the post-cast joint will occur. Therefore, an anti-seepage structure is provided in the post-cast joint, and a drainage structure is provided in the waterproof seepage structure. However, when pouring concrete, the drainage structure is filled with concrete, resulting in poor drainage and affecting the waterproof effect. Utility Model Content

[0019] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0020] As shown in the figure, this embodiment provides a drainage structure for a post-cast zone in a basement, comprising a bottom concrete layer 1, a waterproof structure layer 2 is provided on the top of the bottom concrete layer 1, a waterproof roll 3 is laid on the top of the waterproof structure layer 2, and a top concrete layer 4 is provided above the waterproof roll 3; the top of the waterproof structure layer 2 is provided with an inclined surface 5 inclined inward from both sides, and a water trough 6 is provided between the two inclined surfaces 5, a drainage trough 7 is provided in the water trough 6, and both ends of the drainage trough 7 are connected to the outside, and the top of the drainage trough 7 is covered with a support cover 8, and the support cover 8 is composed of a dense porous steel plate mesh. When pouring the post-cast zone, the waterproof structure layer 2 is first placed in the post-cast zone, and then the asphalt waterproof roll 3 is laid on the waterproof structure layer 2. Through the design of the inclined surface 5, the infiltrated water can flow into the middle water trough 6 along the waterproof roll 3 on the inclined surface 5, and then be discharged to the outside through the drainage trough 7. Before the top concrete layer of the building, a support cover 8 is placed on the drainage ditch 7 to play a supporting and isolating role, preventing concrete from flowing into the drainage ditch 7 and causing blockage when pouring concrete. The support cover 8 is composed of a dense and porous steel plate mesh, and the infiltrated water flows into the drainage ditch 7 through the dense and porous mesh, without affecting the operation of the drainage system.

The arched arch plate 11 can strengthen the support force and reduce the deformation of the support cover 8.

[0023] A cavity structure 12 is formed between the bottom plate 10 and the arch plate 11, and a crushed stone filter layer 13 is filled in the cavity structure 12. The crushed stone filter layer 13 can improve the strength of the entire support cover 8 and can play a filtering role.
