The embodiment provides a construction method for reserving a pipeline opening, which can complete the positioning of sleeves of a plurality of pipeline openings of the same floor layer at one time, and the construction process is simple and quick.

Referring to fig. 1 to 4, the construction method for reserving the pipeline opening includes the following steps:

s1, manufacturing reserved sleeves 1 of the pipeline openings of all parts according to design drawings;

S2, arranging the reserved sleeves 1 at all positions according to the design drawing;

S3, fixedly connecting the reserved sleeves 1 at each part into an integral sleeve mold 2 according to the arrangement positions;

s4, mounting a floor slab template;

S5, installing the integral sleeve mould 2 on the floor slab template according to the design drawing;

S6, pouring concrete;

And S7, when the concrete is solidified to reach the designed strength, pulling out the integral sleeve mould 2 to form reserved pipeline openings of the plurality of pipelines of the floor layer.

preferably, in this embodiment, the shape of the preformed sleeve 1 is a cone, and the small end surface of the preformed sleeve 1 contacts with the floor slab formwork. So set up, can form the reservation pipeline entrance to a cave of back taper, can extract reservation sleeve pipe 1 smoothly. The radial size of the reserved sleeve 1 is larger than the diameter of the pipeline to be installed, so that a construction space for plugging the root of the pipeline is reserved after the pipeline is installed. Specifically, after the pipeline is installed at the reserved pipeline opening, the root of the pipeline is blocked by cement mortar, and preferably, a waterproof agent is doped in the cement mortar. Preferably, the size of the reserved sleeve 1 along the axis of the reserved sleeve is larger than the thickness of a floor layer to be constructed, so that a complete reserved pipeline opening can be constructed, and the forming quality of the concrete surface of the inner wall of the reserved pipeline opening can be prevented from being damaged when the whole sleeve mold 2 is pulled out of concrete.

Specifically, in the present embodiment, the diameter of the large end face of the reserve sleeve 1 is 3cm larger than the diameter of the pipe, and the diameter of the small end face of the reserve sleeve 1 is 1cm larger than the diameter of the pipe.

in the prior art, a PVC sleeve is generally used as a sleeve for reserving a pipe opening. The use of PVC sleeves has the following drawbacks: the PVC casing pipe is easy to shift and deform in the concrete pouring process, and the operation difficulty is high when the PVC casing pipe is dismantled in the later period, so that the forming quality of floor concrete is influenced; the PVC sleeve is easy to shift and deform, so that the reserved pipeline hole cannot meet the design requirement, the pipeline hole is not tightly plugged, the potential water leakage hazard exists, the construction quality is influenced, and the later maintenance difficulty is high; the PVC sleeve cannot be reused after deformation, and material waste is caused.

In order to solve the above problem, in this embodiment, the material of the reserved casing 1 is steel. Optionally, the material of the reserve sleeve 1 is 45 steel. The compressive strength of steel material is far greater than the PVC pipe, but whole sleeve pipe mould 2 cyclic utilization accomplishes the construction of the reservation entrance to a cave of multilayer floor like this, material saving, and the construction is rapid.

in this embodiment, in step S3, the reserved casings 1 at the respective positions are welded to form the integral casing mold 2 by the connecting steel bars. The connecting steel bars are welded on the large end face of the reserved sleeve 1. In step S7, the integral sleeve mold 2 is pulled out by connecting the reinforcing bars. Namely, the connecting steel bar is used as a handle of the whole sleeve mold 2, and the whole sleeve mold 2 is pulled out.

In this embodiment, step S5 includes: at least two reserved sleeves 1 are positioned on a floor slab template so as to install the whole sleeve mold 2 according to design drawings. Because a plurality of reserved sleeves 1 have been connected to be whole sleeve pipe mould 2, only need to reserve sleeve pipe 1 to arbitrary two and fix a position, can accomplish the location of a plurality of reserved sleeves 1, easy operation. Before step S5, a release agent is applied to the portion of the prepared sleeve 1 that can contact the concrete, so that the whole sleeve mold 2 can be smoothly pulled out at a later stage.

Optionally, in this embodiment, the floor slab formwork is an aluminum formwork, and two positioning holes are reserved on the aluminum formwork to position the two reserved sleeves 1. After the construction of the reserved pipeline opening of one floor layer is finished, the aluminum template and the whole sleeve pipe mold 2 are directly used for construction of the reserved pipeline opening of the other floor layer, so that the aluminum template and the whole sleeve pipe mold 2 can be repeatedly used, the site turnover can be rapidly finished, and the construction time is saved.

Of course, in other embodiments, the floor slab mold may also be a wooden template, and the installation and reinforcement of the integral sleeve mold 2 may be performed after the positions of any two reserved sleeves 1 are determined on the wooden template.

the foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but rather is susceptible to various changes and modifications without departing from the spirit and scope of the invention, which changes and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
