Embodiment Construction

[0029] Examples see figure 1 Shown, a kind of PVC drainage directly buried pipe fitting construction method is characterized in that: comprises the following steps:

[0030] Step 1: Divide the whole building into several measurement sections according to the height of the building; each measurement section has 4 to 5 floors

[0031] Step 2, supporting the ground formwork on the lower floor of the first measurement section;

[0032] Step 3: According to the construction drawings, refer to the axis of the slab surface and the measurement control line, supplemented by the center line of the beam, locate the center coordinates of each pipe fitting on the lower ground formwork of the first measurement section, determine the installation position of the pipe fittings, and install the pipe fittings with screws Go to the lower ground formwork of the first measurement section; use the center coordinates as the origin, take the outer diameter of the pipe fittings to be installed as the...

Abstract

The invention relates to a construction method for a PVC(poly vinyl chloride) drainage direct-buried pipe fitting, which belongs to the technical field of device installation during the building construction. The pipe fitting is installed on a floor template to be integrally cast together with the ground, so that the integrity of a structure floor slab is increased, the procedure of the later construction is reduced and water seepage of the floor slab at the position of the pipe fitting is prevented. Simultaneously, the remaining layers in each measurement section can be accurately and fast located by an infrared vertical meter assisted by auxiliary locating correction of an axis and a control line at this layer by dividing the entire construction process into rational measurement sections, calibrating and locating when a reference layer is installed. The construction procedure is simplified and the construction efficiency is improved while the locating accuracy is not reduced. The construction method, disclosed by the invention, can be widely applied to installation of the drainage pipe fitting in the construction of construction equipment.

Description

technical field [0001] The invention relates to a construction method of a drainage pipe fitting. Background technique [0002] Pipe installation is an important process in building construction. The traditional installation method is: first construct the civil engineering part, and reserve holes in the corresponding floor positions, and then uniformly install the drainage pipe fittings after the construction of the structural part is completed. During the installation process, it is necessary to correct the reserved holes, chisel the holes, hang the formwork, and seal the gaps between the pipes and the holes. The installation cost is high, and there are often cases of civil engineering, water and electricity cross operations, which reduces the construction efficiency. In addition, due to the post-installation construction method, since the gap between the pipes and the hole is small, the plugging can only be based on the experience of the construction personnel, and often ...
