Problems solved by technology

However, this kind of treatment may cause the following disadvantages: 1. The toilet and kitchen drainage pipes pass through the floor and are prone to water seepage; 2. There are many technological processes where the drainage pipes pass through the floor, including many technological processes such as leaving holes, mold release, and filling holes; 3 . Waste of manpower and construction period; 4. It is troublesome to repair the reserved hole in the later stage, such as mold making, hanging mold, grouting, etc.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with specific embodiment:

[0014] A pre-embedding process for drainage pipe collars, specifically comprising the following steps:

[0015] a. Before binding the steel bars, lay out the wires on the supported platform template according to the installation size of the appliance, and determine the pre-embedded position of each drainage pipe hoop;

[0016] b. Mark the processed drainage pipe hoops of different sizes and models, and fix and install each drainage pipe hoop to the corresponding pre-embedded position according to the construction drawings. The drainage pipe hoops are fixed with the platform template by iron nails, and the fixed type ensures The verticality of the drainage pipe hoop makes its bottom surface contact with the surface of the formwork to prevent the drainage pipe hoop from sinking into the concrete layer after pouring;

[0017] c. Lay steel bars on the platform formwork, and at ...

Abstract

The invention discloses a pre-burying technology of a drain pipe hoop, which comprises the steps of pay-off, mounting and fixing of the drain pipe hoop, reinforcement laying, concrete pouring, and drain pipe hoop inspection. According to the pre-burying technology of the drain pipe hoop, the drain pipe hoop is pre-buried during the concrete pouring; secondary pouring in a later stage is omitted, and the long-term troubled construction problem of plate leakage in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a pre-embedding process of drainage pipe hoops. Background technique [0002] Nowadays, the drainage pipes of kitchens and bathrooms pass through the floor, mostly adopting the traditional method of reserving holes, installing and fixing the drain pipes, hanging the formwork, and performing secondary grouting. The mold with matching pipe diameter (the mold size is generally two grades larger than the diameter of the drainage pipe) is firmly fixed with the surrounding steel bars and formwork. After the concrete is poured and tamped, the mold is pulled out to expose the reserved hole. [0003] Then install the drainage pipe in the reserved hole and perform secondary grouting, and repair the gap between the reserved hole and the drainage pipe with cement mortar. However, this kind of treatment may cause the following disadvantages: 1. The toilet and kitchen drainage pipes pass ...
