Description

A kind of W type flexible anti-shock iron drain-pipe construction

Technical field

The present invention relates to a kind of method of construction, is specifically a kind of W type flexible anti-shock iron drain-pipe construction.

Background technique

Construction drainage is a critical function part in construction engineering.Tradition waste pipe construction has that the difficulty of installation, working life are short, noise greatly, not anticorrosive, the easy shortcoming such as aging.

Summary of the invention

Technical problem to be solved by this invention be just to provide a kind of have can synchronous construction, tubing utilization ratio is high, be convenient to that pipeline is clear and coherent, the construction of reduction of erection time.

For achieving the above object, the present invention adopts following technological scheme: a kind of W type flexible anti-shock iron drain-pipe construction, comprises the following steps successively:

A) measurement, unwrapping wire; Press construction drawing measurement, unwrapping wire, location, the pre-buried sleeve pipe of passing through floors face and body of wall is than the bigger setting of required caliber; Press construction drawing measurement, unwrapping wire, and determine required pipe length according to its result; The position of arranging according to definite of required pipe length, suspension bracket;

B) pipeline prop up, suspension bracket install; Vertical pipe support, suspension bracket are set, and soil stack adopts support to be fixed in building bearing structure, and riser cradle is every layer of setting;

C) pipeline is installed; Stainless steel lathe dog is first enclosed within on the pipe shaft of interface one end; One headgear of rubber ring, on the mouth of pipe of a mouthpiece, and should be inserted in to prescribed depth; Outwards overturn in the other end of rubber ring; The pipe fitting that will connect or the mouth of pipe of straight tube are put into the rubber ring mouth of upset, and calibration orientation, turns back normal state the rubber ring mouth of upset; Again calibrate the gradient or sag or the orientation of pipeline, tentatively use suspension and support fixing tube, mobile stainless steel lathe dog is enclosed within outside rubber ring, tightens the clamping bolt on clip with socket wrench specially adapted for it, and interface just completes.But should be with the bolt tightening by suspension and support, make pipeline reliably fixing;

D) arm is installed;

E) be connected with other pipe, annex and watering equipment;

F) water filling test;

G) water test;

H) through ball test.

W type flexible anti-shock iron drain-pipe construction of the present invention has can synchronous construction, tubing utilization ratio is high, be convenient to that pipeline is clear and coherent, the reduction of erection time, has improved economic benefit.Simple to operate, easy to maintenance.Housing type joint is lightweight, only needs two clamping bolts, need not install sealing gasket additional, when installation without particular/special requirement.Vibration isolation: housing type joint intermediate rubber circle noise capable of blocking; And can prevent Vibration propagation.Use extensively: housing type joint can be connected with the pipeline of any equal caliber, can play a protective role especially to anti-corrosion pipeline.Invest little: special device is cheap.

Embodiment

W type flexible anti-shock iron drain-pipe construction of the present invention, is characterized in that: comprise the following steps successively:

A) measurement, unwrapping wire; Press construction drawing measurement, unwrapping wire, location, the pre-buried sleeve pipe of passing through floors face and body of wall is than the bigger setting of required caliber; Press construction drawing measurement, unwrapping wire, and determine required pipe length according to its result; The position of arranging according to definite of required pipe length, suspension bracket;

B) pipeline prop up, suspension bracket install; Vertical pipe support, suspension bracket are set, and soil stack adopts support to be fixed in building bearing structure, and riser cradle is every layer of setting;

C) pipeline is installed; Stainless steel lathe dog is first enclosed within on the pipe shaft of interface one end; One headgear of rubber ring, on the mouth of pipe of a mouthpiece, and should be inserted in to prescribed depth; Outwards overturn in the other end of rubber ring; The pipe fitting that will connect or the mouth of pipe of straight tube are put into the rubber ring mouth of upset, and calibration orientation, turns back normal state the rubber ring mouth of upset; Again calibrate the gradient or sag or the orientation of pipeline, tentatively use suspension and support fixing tube, mobile stainless steel lathe dog is enclosed within outside rubber ring, tightens the clamping bolt on clip with socket wrench specially adapted for it, and interface just completes.But should be with the bolt tightening by suspension and support, make pipeline reliably fixing;

D) arm is installed, and branch drain starting point is directly connected with sanitary equipment, floor drain, rain bucket, directly bears the shock vibration of current, so arm fixation problem more should be paid attention to.Below point, two kinds of situations are fixing respectively: 1) single accessory is connected with pipe, are fixed support in elbow bottom; 2) multiple accessories are connected with pipe, and each accessory place is fixed support and suspension bracket space.;

E) be connected with other pipe, annex and watering equipment;

F) water filling test must do water filling test to hidden or buried drainage pipe before hidden, and its height of pouring water should be not less than top edge or the ground floor height of bottom sanitary ware, after the full water 15min water surface declines, fill and observe 5min, liquid level does not fall, and pipeline and interface ne-leakage are qualified; In work progress, for can find out in time whether have construction bad outside, should be in advance by pipe-line system subregion, segmentation, the method that adopts as far as possible local completion, part to pour water, requires to carry out water filling test in accordance with regulations; When water filling test, generally taking clean water as medium, water filling test is carried out by national existing relevant specification standard;

G) water test, the water test of rain drainage pipe and roof fire hydrant trial fire test are carried out simultaneously, utilize the discharge water of roof fire hydrant trial fire test to be discharged to respectively each Water in Rainwater Drainage mouth of a river of roofing, observe, test water can enter storm sewer by rain water on roof mouth smoothly, drain into outdoor rainwater inspection well, pipeline is unobstructed, and roofing is without seeping phenomenon.Discharge water in order to meet open 1/3 water distribution point simultaneously, point 3 water tests, go out the corresponding pipeline in family by each drainage duct and carry out water test, then separate each toilet simultaneously from sanitary ware, floor drain draining.Check each pipe drainage situation, all unimpeded without stopping up, can be discharged in time outdoor sewage inspection shaft, pipeline and each interface ne-leakage phenomenon;

H) through ball test, the plastics that sphere diameter are not less than to this caliber 2/3 from the topmost part of soil stack or the starting point inspection socket of transverse drainage main are tried and are put into the topmost part of soil stack or the starting point inspection socket of transverse drainage main, simultaneously toward the flushing of pouring water in the topmost part of soil stack or the starting point inspection socket of transverse drainage main, corresponding waste pipe goes out the interior outlet that seals inspection shaft with grid of outdoor sewage inspection shaft at family, this ball pours inspection shaft smoothly with current, be truncated to and try, try unblocked qualified.

Above-described embodiment is to explanation of the present invention, is not limitation of the invention, any scheme after simple transformation of the present invention is all belonged to protection scope of the present invention.
