Description
Technical Field
The invention relates to a threading mode of a line pipe, in particular to an installation method for threading of the line pipe.
Background
In building installation engineering, especially civil house building engineering, most of the methods adopt that a wire pipe is pre-buried in a wall body, and an electric wire is penetrated after the wire pipe is buried, so that the method is commonly called buried type, and the method is attractive and does not influence the construction of other decoration and finishing. However, the hidden burying has a disadvantage that the difficulty is large when the electric wire is penetrated. Because the general majority of secretly buried is plastics tubular product, when concrete structure construction, very easily step on flat, step on, extrude destruction with pre-buried spool, infiltration grout, or the spool corner is handled improperly when the installation, does not set up to the circular arc and is directly the right angle bend, causes the electric wire to wear to establish the difficulty. The traditional threading method is to use a hard iron wire, firstly to penetrate into a wire tube from the opening of the mounting wire box, then to tie up one end of the wire by the iron wire after penetrating out from the other end, and then to drag the wire into the wire tube until the wire penetrates out from the opening of the mounting wire box at the other end. The method firstly needs to manually penetrate the whole iron wire into the pre-buried wire pipe little by little, the penetrating time is long, especially in large-area rooms, the wire pipe arrangement length is long, the turning angles are more, and the difficulty in penetrating the iron wire is higher. If a section of wire pipe is just blocked by foreign matters, the iron wire is drawn out again, and the wire can be threaded after the blockage is cleaned, so that the time is prolonged.
The known methods of conduit threading therefore suffer from the inconveniences and problems described above.

In the figure: the wire box comprises 1 embedded wire pipe, 2 wire penetrating ports, 3 wire penetrating ports, 4 embedded wire boxes, 5 corner heads, 6 plastic hard pipes, 7 dust absorption hoses, 8 dust collectors, 9 structural wall bodies and 10A mark numbers.
Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
Referring now to fig. 1, fig. 1 is a schematic view of a threading installation structure of a conduit according to an embodiment of the present invention.
The installation method for the rapid pipeline penetration comprises the following steps:
firstly, in a floor structure wall 9, according to an installation drawing of an embedded line pipe 1, finding out two installation ports of a pipeline loop (a switch installation port and an electric appliance installation port are used as an electric wire penetrating port 2 and an electric wire penetrating port 3), then respectively marking the same mark number at the two installation ports, such as A10, wherein the two subsequent installation ports are marked with A, and can also be numbered by using ordinal numbers.
Secondly, preparing a bundle of plastic ropes at two lower installation ports which are identical in number and easy to operate, releasing the plastic ropes with a certain length according to the estimated length of the pipeline loop, and then extending the end heads of the plastic ropes at the release ends into the inlets of the line pipes in the line box of the switch, wherein the length of the plastic ropes extending into the inlets is 5-8 cm.
Thirdly, another person stands at the other end mounting opening (another position with the same number) of the pipeline loop at the moment, a plastic hard pipe 6 is used, one end of the plastic hard pipe is connected with a dust collection hose 7 of a dust collector 8, the other end of the plastic hard pipe is connected with a short pipe bending head 5, the length of the short pipe bending head is 3-5cm, and the diameter of the pipe bending head is slightly smaller than that of the pipeline of the loop. The pipe bending head is stretched into a pipeline outlet at the mounting opening, then the dust collector is started, and the pipeline loop is a closed loop, and the other end of the pipeline loop is provided with a plastic rope, so that the plastic rope at the other end can be sucked into the pipeline under the action of suction force until the plastic rope is sucked out of the outlet of the pipe mounting opening.
Fourthly, after the exposed length of the plastic rope at the penetrating end is ensured to be 3-4cm, cutting off the plastic rope at the mounting opening of the penetrating plastic wire after the plastic rope is exposed for 3-4 cm;
and fifthly, using a piece of plastic foam which has the same shape as the pre-buried wire box 4 and slightly larger size to block the mounting opening, so that the plastic rope head can be pressed, the plastic rope head is prevented from being retracted into the wire box, and cement mortar, slurry and the like can be prevented from being pasted into the mounting opening to influence the installation of the electric wire. If the plastic rope can be smoothly sucked out, the inside of the wire pipe is proved to be smooth and not to be blocked.
Sixthly, for the pipeline which can not suck out the plastic rope smoothly, at least a certain section (part) of the pipeline embedded in the concrete structure is blocked by foreign matters or the pipeline pipe is extruded and deformed, and only measures can be taken to dredge or re-arrange the pipeline, and the situation that the pipeline cannot penetrate and is blocked is indicated by X beside the number of the installation opening.
And seventhly, directly binding the end of the wire at one end of the mounting opening by using a plastic rope in the wire tube when the pipeline is mounted, pulling the plastic rope at the other end, penetrating the wire into the wire tube until the wire is pulled out to the other end, and finishing the mounting of the wire in the wire tube.
The installation method for threading the line pipe has the advantages that the installation speed is high, the installation of the plastic rope only needs ten seconds, and the time for threading the line pipe is greatly reduced. The installation speed is fast, and the cost of plastics rope is cheap with low costs, can continue to recycle after taking out, and is not extravagant.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Accordingly, all equivalents are intended to fall within the scope of the invention, which is defined in the claims.
