Description
Technical field
The present invention relates to supply water, particularly a kind of water supply line is cut off the water supply the construction method of not cutting off the water installed and keep in repair.
Background technology
With the quick continuous development in city, the municipal water supply branch pipe(tube) facility of many 1970s and 1980s layings starts
Existing many problems, remote due to the age, the valve on pipeline is not nearly all effective or just can not find at all, to present pipeline
Rebuilding construction, such as family table transformation, low pressure transformation, leak repairing all bring many troubles, water to stop not living, it is impossible to carry out repacking and
Maintenance, and when reequiping and keep in repair, the first treatment measures is to need to search upper level main pipe valve closing step by step, causes to stop
Water area is very big, and masses' suggestion is very big, and second measure is that band water is rushed to do, and must be caused with pumping water, operating personnel's submersible
Water resource is wasted in a large number and made troubles to periphery masses trip, and besides especially winter construction, workman is difficult to bear this
The pain that submersible brings, constructional difficulties, therefore, how to solve water supply line and cut off the water supply to enter water supply line
Row transformation and maintenance are the technical problems for needing conscientiously to solve.
The content of the invention
For above-mentioned situation, to overcome the defect of prior art, it is an object of the present invention to provide a kind of water supply line cut off the water supply
Install and keep in repair construction method of not cutting off the water, can effectively solving pipeline modification and maintenance when water stop not living, the problem of constructional difficulties.
The technical scheme that the present invention is solved is that Hough threeway is sleeved on into the periphery of conduit pipeline, and by Hough threeway
Arm is connected with one end of gate valve, and the other end of gate valve connects with opening drill body phase of not cutting off the water, and with not cutting off the water, opening drill is needing construction
Conduit pipeline on bore opening, after conduit pipeline opening, extraction is not cut off the water the drilling rod of opening drill, and puts down gate valve, prevents from metalling run out,
Then, change the drilling rod of opening drill of not cutting off the water into rubber plug hollow jacking bar, and load onto on the hollow jacking bar of rubber plug
Inflatable rubber plug, opens gate valve, by the one end of the hollow jacking bar of rubber plug equipped with rubber plug towards conduit pipeline,
And the hollow jacking bar of rubber plug is promoted, rubber plug Jing openings are advanced into conduit pipeline inner chamber, then, rotational positioning set
And tighten, the hollow jacking bar of rubber plug is fixed, manual stamper is connected on joint, manual pressure, make rubber plug swollen
Swollen substantial conduit pipeline cross section, makes conduit pipeline cut off the water supply, you can to transform as needed the downstream of conduit pipeline opening
Install or maintenance construction；After construction is finished, manual stamper is laid down, rubber plug is deflated by the hollow jacking bar of rubber plug,
Come loose positioning sleeve, while the hollow jacking bar of rubber plug and rubber plug are taken out, puts down gate and valve, closes Hough threeway
Arm, the opening drill body that then will not cut off the water to be unloaded be capable of achieving from gate valve and water supply line is cut off the water supply installation and keep in repair.
The inventive method is simple to operation, easy to use, low cost, can effectively solving pipeline modification and during maintenance construction not
The problem cut off the water, economic and social benefit is huge.
Description of the drawings
Fig. 1 is the construction technology equipment drawing of the present invention.
Specific embodiment
The specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing.
The construction method of not cutting off the water installed and keep in repair as shown in figure 1, a kind of water supply line is cut off the water supply, Hough threeway 1 is set with
In the periphery of conduit pipeline 15, and the arm 2 of Hough threeway 1 is connected with one end of gate valve 4, the other end of gate valve 4 stops with not
Water opening drill body 12 is connected, and opening is bored on the conduit pipeline 15 that need to be constructed with opening drill of not cutting off the water, after conduit pipeline 15 is open,
Extract the drilling rod of opening drill of not cutting off the water out, and put down gate valve 4, prevent from metalling run out, then, change the drilling rod of opening drill of not cutting off the water into rubber
The hollow jacking bar 3 of plug, and inflatable rubber plug 9 is loaded onto on the hollow jacking bar 3 of rubber plug, gate valve 4 is opened, by rubber
The one end of the hollow jacking bar 3 of glue plug equipped with rubber plug 9 promotes the hollow jacking bar 3 of rubber plug towards conduit pipeline 15,
The Jing of rubber plug 9 openings are advanced into the inner chamber of conduit pipeline 15, then, rotational positioning set 13 is simultaneously tightened, fixed rubber plug
Hollow jacking bar 3, manual stamper is connected on joint 8, manual pressure, makes the expansion of rubber plug 9 enrich conduit pipeline 15
Cross section, makes conduit pipeline 15 cut off the water supply, you can carry out improvement and installation or maintenance as needed to the downstream of the opening of conduit pipeline 15
Construction；After construction is finished, manual stamper is laid down, rubber plug 9 is deflated by the hollow jacking bar 3 of rubber plug, and come loose positioning
