Embodiment approach

[0028] Such as Figure 1 to Figure 3 As shown, a one-time pre-buried water stop section for drainage in construction projects includes a connecting pipe 1, a water stop ring 2 is provided on the connection pipe 1, a water stop ring 3 is provided on the water stop ring 2, The bottom of the connecting pipe 1 adopts a double-layer inserting socket 4 structure, and the outer edge of the bottom of the connecting pipe 1 is provided with three connecting supports 5, and the three connecting supports 5 are symmetrical about the axis center of the connecting pipe 1 Distribution, the connecting support 5 is provided with a fixing hole 7. The triangular symmetrical distribution structure of the connecting support 5 greatly improves the reliability of the connection between the embedded joint and the bottom form, so that the position of the embedded joint will not shift when the concrete is poured, and it is also convenient for plastering the bottom surface after the bottom form is remove...

Abstract

The invention discloses a one-time embedded water-stop section for construction engineering drainage and a construction method of the one-time embedded water-stop section, which belong to the technical field of construction engineering embedded parts and construction thereof. The construction method comprises the following steps of: mounting a bottom die of a cast-in-place floor; mounting the one-time embedded water-stop section for the construction engineering drainage on the bottom die according to a design requirement, wherein the outer side of the bottom edge of the one-time embedded water-stop section for the construction engineering drainage is provided with a connecting supporting seat; fixing the one-time embedded water-stop section for the construction engineering drainage on the bottom die; covering a top cover on the top part of the one-time embedded water-stop section for the construction engineering drainage; casting concrete in situ on the bottom die; compacting the concrete by vibrating; and maintaining the cast floor. In the construction method, the water-stop section is embedded once, so that the construction processes are greatly reduced, the construction efficiency is significantly improved, and simultaneously a casing pipe is not required to be embedded and the energy source and the cost are saved. The construction method is particularly suitable for the construction of the one-time embedded water-stop section for the construction engineering drainage on construction engineering cast-in-place occasions.

Description

technical field [0001] The invention relates to a pipe connection joint used in cast-in-place occasions, and a construction method for the joint in a concrete cast-in-place floor slab of construction engineering. Background technique [0002] At present, for water pipe joints in cast-in-place occasions, there is a patent named CN201535401 as the patent name of the cast-in-place sealing water-stop joint. The water-stop joint disclosed in this patent overcomes the gap between the reserved cavity and the water pipe in the traditional construction method. Cause leakage problem, and the water stop section also solves the problem of water leakage caused by long-term use. However, there are still some problems in this water-stop section. For example, the bottom edge adopts a circular or polygonal structure, which puts forward high requirements on the flatness of the bottom form installed with it during the construction process. If there is a size error between the bottom form and t...
