Abstract
The invention discloses a method for quickly drilling a hole in a steel pipe with water and connecting a branch pipe to the steel pipe. The method aims to overcome the defects that in the prior art, a hole cannot be drilled in a steel pipe with a large amount of water, then a branch steel pipe cannot be connected to the steel pipe, waiting time is long and water supply to other branch pipes is affected if hole drilling and butt joint are conducted after the water is discharged, and waste is caused when the water is discharged. The method comprises the steps of manufacturing a hollow water drill bit, welding a water drill bit locating pipe at the position, where the hole needs to be drilled, in the main steel pipe, welding the branching steel pipe at the position, outside the locating pipe, of the main steel pipe concentrically, installing a ball valve on the branch steel pipe, opening the ball valve, drilling the hole between the branch steel pipe and the locating pipe through the water drill bit, taking out the cut portion of the locating pipe, closing the ball valve and connecting the branch pipe. According to the method, the water inside the main steel pipe does not need to be discharged, the hole is drilled in the pipe wall without electric welding or gas welding, time used for connecting the branch steel pipe is saved by four to five hours compared with that spent in the prior art, the working efficiency is high, welding quality can be ensured, water waste is reduced, and water usage of other places is not affected in the process of connecting the branch pipe.
Description
Technical field
The invention belongs to adapting method, specifically a kind of on the steel pipe main pipeline with water perforate connect the method for arm.
Background technique
Along with the continuous expansion of business, the goods yard area of port and pier is in continuous expansion; The raising of environmental protection requirement also constantly increases the water consumption in stockyard and water place, and therefore, the stockyard water after expansion, just need to increase lateral from main pipeline and satisfy the demand.
While installing the branch steel pipe of new system additional on the steel pipe of main pipeline, because there being a large amount of water in main pipeline, if first open the branched hole adapter that discharges water again from main pipeline, from the perforate welding branch steel pipe that discharges water, complete and often need 5-6 hour, the adapter time, long not only impact newly increased the use of part, but also can affect the water of other existing goods yard arms, the water of these outflows causes very large waste because depositing nowhere.
If take over electric welding or gas welding punching on the steel pipe of main pipeline that has water, just reaming again after main pipeline has water to ooze out, still will wait for that the water of pipeline middle and upper part flows out, and has living space and could continue perforate welding in pipe, does like this and still exists above-mentioned problem.
Summary of the invention
Technical problem to be solved by this invention is, overcome prior art and cannot connect branch's steel pipe by opening on the steel pipe that has the large water gaging of water, if open butt joint again after discharging water, the water supply of other arms is grown, affected to stand-by period, and the wasting shortcoming that discharges water, providing a kind of is having on water steel pipe perforate fast connect the method for arm.
The problems referred to above that exist in order to solve prior art, the present invention adopts following technical proposals to realize:
One, select water drill bit:
Select its external diameter to be slightly less than at the water drill bit of steel pipe supervisor Shang Xujie branch pipe diameter standby;
Two, water drill bit location when the steel pipe that needs perforate is responsible for boring:
On steel pipe supervisor, determine behind the position of perforate, centered by the docking point on described steel pipe supervisor, weld the positioning pipe that one section of diameter is less than described water drill bit internal diameter;
San, welded and installed branch steel pipe, prepare punching:
(1) branch's steel pipe of top band mounting flange, with the concentric external diameter that is greater than water drill bit at the internal diameter of steel pipe supervisor's tube wall Shang， branch steel pipe that welds of described positioning pipe;
(2) by the flange plate abutting joint on the mounting flange on ball valve and described branch steel pipe, and ball valve is located to whole open modes;
Four, punching connecting branch:
(1) in described branch steel pipe, add water, with jackhammer, clamp described water drill bit, water drill bit, by the ball valve orifice of opening, extend into the space between described positioning pipe and branch's steel pipe simultaneously, the punching of spudding on steel pipe supervisor's tube wall, until beat tube wall;
(2) extract water drill bit out, by cutting down from steel pipe supervisor, take out rapidly and close ball valve with the tube wall of positioning pipe in branch's steel pipe, on the flange plate of the ball valve the other end, connect the water pipe that can guide place to use into.
Originally return and there is following technical characteristics:
The described branch's steel pipe length being welded on steel pipe supervisor tube wall is 95-110 millimeters;
The described branch's steel pipe length being welded on steel pipe supervisor tube wall is 100 millimeters;
The length of described positioning pipe is 45-55 millimeters;
The length of described positioning pipe is 50 millimeters.
Advantage of the present invention and good effect are, with said method, in the steel pipe supervisor tube wall perforate with water, dock branch's steel pipe, owing to the water in steel pipe supervisor need not being emitted, also without electric welding or gas welding, on tube wall, punch, first weld branch's steel pipe, after installing ball valve, open ball valve water drill bit band water boring again, whole boring connects the process of branch's steel pipe and only uses 0.5-1 hour, than prior art, connect branch's steel pipe, from perforate, discharge water and reach welding condition, connecing each branch's steel pipe will save time more than 4---5 hour, greatly improved working efficiency, and can guarantee weld seam welding quality, reduced the waste of water, in adapter process, do not affect other local waters in stockyard yet.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic that fast opening of the present invention connects arm.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1, for perforate on the tube wall steel pipe supervisor 1 connects the schematic diagram of branch's steel pipe 2, is that minute following steps realize:
One, select water drill bit 5:
Select its external diameter to be slightly less than to be responsible for the water drill bit 5 of 1 Shang Xujie branch steel pipe 2 internal diameters at steel pipe standby;
Two, location when the steel pipe that needs perforate is responsible on 1 tube wall 5 boring of water drill bit:
On steel pipe supervisor 1, determine the position of perforate, centered by described steel pipe is responsible for the docking point on 1 tube wall, weld the positioning pipe 3 that one section of diameter is less than described water drill bit 5 internal diameters, as the drilling rod 5.1 Internal hole positionings uses of perforate water drill bit 5;
