Problems solved by technology
Since the first filling part 93' and the first floor 91' are poured in batches, and during the pouring process of the first filling part 93', there is no support of the lower formwork, so the concrete of the first filling part 93' cannot Being compacted, it is easy to cause a gap between the contact surface of the first filling part 93' and the first reserved hole 911', and the contact surface of the first filling part 93' and the first drainage pipe 92', resulting in a gap in the reserved hole drainage pipe. The installation structure is prone to leakage problems

Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0039] refer to figure 1 , is an anti-seepage structure with reserved holes for kitchen and bathroom disclosed by the present invention, comprising a concrete floor slab 1, a drainage pipe and a filling part filled between the outer wall of the drainage pipe and the concrete floor slab 1. The concrete floor slab 1 has a reserved hole 11 in which the water supply and drainage pipes are installed vertically. The reserved hole 11 is in the shape of an inverted cone.
[0040] The drainage pipeline includes a supporting outer pipe 2 and a drainage inner pipe 3 coaxially installed in the supporting outer pipe 2 .
[0041] refer to figure 1 and figure 2 The supporting outer pipe 2 includes, from top to bottom, an upper installation section 21 above the concrete floor slab 1 , a connecting section facing the inner wall of the reserved hole 11 , and a lower ins...

The invention discloses an anti-seepage structure and a construction method for a reserved hole in the kitchen and bathroom, which solves the problem that the anti-seepage effect of the anti-seepage structure of the reserved hole in the kitchen and bathroom needs to be improved at the present stage. The main point of the technical solution is a leak-proof structure with reserved holes in the kitchen and bathroom, including a concrete floor slab, and the concrete floor slab is provided with a reserved hole running through its upper and lower end surfaces, and a drainage pipe is arranged in the reserved hole. The drainage pipe has a connecting section facing the reserved hole, a filling part is provided between the reserved hole and the connecting section, and the drainage pipe can also be detachably installed with a lower end opening of the reserved hole Covered template parts, the reserved hole is in the shape of an inverted truncated cone, the drainage pipe has a support frustum with an outer diameter that gradually decreases along its height direction, and the filling part includes a dense filling located outside the support frustum layer, the anti-seepage effect of the anti-seepage structure with holes reserved in the kitchen and bathroom is ideal.
Description
technical field [0001] The invention relates to the field of fixing building floors, in particular to an anti-leakage structure and a construction method for a reserved hole in a kitchen and bathroom. Background technique [0002] In the construction of fixed buildings, the concrete floor slab of the kitchen and bathroom usually has reserved holes for the installation of drainage pipes in subsequent projects. refer to Figure 8 , a reserved hole drainage pipeline installation structure, including a first floor 91' and a first drainage pipeline 92', the first floor 91' is provided with a first reserved hole 911', the outer diameter of the first drainage pipeline 92' It is smaller than the outer diameter of the first reserved hole 911' and runs through the first reserved hole 911' up and down, and the first filling part is filled with concrete between the outer wall of the first drainage pipe 92' and the inner wall of the first reserved hole 911' 93'. Since the first filling...
