The construction method includes the steps of construction preparation, installation of a rainwater drain, installation of a suspension fixing system, fusion welding of a high-density polyethylene (HDPE) pipe and the like. The method is convenient to construct and good in construction quality.
Description
Technical field
The present invention relates to a kind of siphon rainwater drainage system job practices.
Background technology
Along with new material, new technology, new technology, new method are constantly promoted and used to building trade in recent years, the siphon architecture drainage system against rain of HDPE tubing more and more is applied in some large spans, the large-area building, particularly the requirement of architectural space improved constantly, after the architectural successful application of some venue classes, the system of this kind new material technology technique has obtained developing rapidly especially.But the problems such as existing job practices exists construction complicated, and quality is not good.
Summary of the invention
The object of the present invention is to provide a kind of easy construction, the siphon rainwater drainage system job practices that construction quality is good.
Technical solution of the present invention is:
A kind of siphon rainwater drainage system job practices is characterized in that: comprise the following steps:
(1) preparation of construction:
Conscientiously examine drawing, pass floor and shear wall place reserving hole at pipeline, when roof structure was constructed, with reference to civil engineering figure, according to axis, absolute altitude and water were executed figure and are cooperated embedment for Civil Works to meet roof drain installation hole; Or directly the roof drain seat is embedded in the roofing concrete together with the protection screw, reserve roofing levelling face thickness when pre-buried;
(2) roof drain is installed:
When roofing construction, to press design drawing and cooperate embedment for Civil Works hydrocone type roof drain position, the hydrocone type roof drain quantity of each watershed of roofing is no less than 2, and the spacing between the roof drain is no more than 20m; The hydrocone type roof drain is apart from roofing Edge Distance 1m＜distance＜10m; The hydrocone type roof drain is connected reliably with roofing and pipeline, when system connects a plurality of hydrocone type roof drain, hydrocone type roof drain drainage connecting pipe is connected on the hanging pipe, directly is not connected on the top of rain leader downspout, and the hydrocone type roof drain that accesses same hanging pipe is at same roofing absolute altitude; Roof drain installs in the rear attention and after the foreign material cleaning miscellaneous part is installed again, in order to avoid stop up, and carry out the finished product protection of corresponding site;
(3) the suspention fixed system is installed:
Fixture is set when the HDPE(high density polyethylene (HDPE)) pipe-line system is installed, adopts the suspention fixed system, every interval≤5m arranges a fixed support on hanging pipe, and this point is fixed with the suspention beam, and is immovable;
Before the pipe laying system, fixed system is installed first; Suspention fixed system for the suspention horizontal pipe, quantity and position according to design are fixed on installation sheet on the steel bar concrete with expansion bolt, with screw rod, square steel card zinc-plated square steel pipe is fixed up, Level-adjusting is to meeting designing requirement, in order to carry out the installation of horizontal pipe;
For the fastening devices of standpipe, according to designing requirement and regulation and stipulation installation sheet is fixed on pillar or the wall equally, in order to carry out the installation of riser clamp;
Fixing of standpipe: standpipe is fixed in wall, post or other building structure with standpipe card, standpipe installation sheet, connecting thread bar;
Unwrapping wire and installation sheet fixing: whether have with building and other pipeline according to the drawing location dimension scene of checking first before the unwrapping wire and conflict, emit again straight line, make the position of installation sheet at straight line;
The horizontal tube installation sheet whenever is no more than 2.5m and arranges one, and the standpipe installation sheet is no more than 15 times of calibers and arranges one;
Again backguy inspection after installation sheet installs is if the center of installation sheet not point-blank, adjusts by top elongated hole;
No matter be horizontal suspension pipe or standpipe, after all plate holes through walls should being got through, draw logical line, to guarantee its straight cis degree;
(4) melting welding of HDPE pipe
Operating procedure:
The first step: weld preparation
Remove two pipe end dirts with clean cloth, select corresponding anchor clamps and carriage according to different calibers, the tubing that will weld places on anchor clamps and the carriage, and the length that two ends are stretched out is suitable, should be short as far as possible under the requirement of satisfying milling and heating, be generally 25-30mm; If necessary, the part beyond the tubing frame holds up with supporter, makes tubing axis and anchor clamps centerline in sustained height, then fixes with anchor clamps;
Insert milling cutter, open first the milling cutter power switch, then close up two tubing welding endss, and pressure in addition, until after two ends all have continuous smear metal to occur, remove pressure, back out again adjustable shelf, turn off the milling cutter power supply;
Take out milling cutter, close up two pipe ends, check two end milling situations:
Pipe end is vertical 90 °, and dislocation is no more than 1mm, and the maximal clearance of closed pipe end is no more than 0.3mm;
Second step: hot melt
Electric hot plate is inserted between two pipe ends, rotate pressurized handgrip and observe gauge hand, reach the pressure P of regulation, heated pressure remains to until want the whole circle fusing rim charge that forms of the accessory of welding on every side, effect is the unevenness on the rapid smooth tube end face and effectively promotes plasticizing, until the minimum crimping in both sides reaches specified altitude H1;

Pressure is reduced to 10% of rule heated pressure P, makes just to keep close contact between end surfaces and the electric hot plate, continue to be heated to official hour T1;
The 3rd step: switch
After heating is finished, back out anchor clamps, take out electric hot plate, then close up two pipe ends, be no more than 5 seconds its switching time;
The 4th step: docking
Slowly pressurize to the pipe end that closes up by pressurized handgrip, at official hour T2 pressure rise is arrived the setting P identical with heated pressure, the locking retaining brake keeps pressure;
The 5th step: cooling
Unclamp retaining brake behind the T3 cool time that pressure is kept stipulating at least, opens anchor clamps, takes out the good pipe of welding;
Be not more than the pipe of 75mm for caliber, can not pass through operating desk during docking, directly be docking together with hand.
Easy construction of the present invention, construction quality is good, and siphon rainwater head adopts the fixing mode of machinery, can guarantee the sealing that roof drain is connected with roofing, need not to do preservative treatment during installation, and the excellent corrosive nature of doing is arranged.The HDPE(high density polyethylene (HDPE) that adopts) pipe can bear larger impact force, and can not break, fracture because of flexure plane, and corrosion resistance, and its anti-extreme temperature range is large (30 ℃-100 ℃) also, and the tubing own wt is light, constructability.System pipeline need not gradient row and establishes, and vent flow is large, and required ground underground buried tube is less, and the use amount of pipeline and accessory is few, reduces the site operation amount, reduces drainage pipe diameter, saves installing space, and pipeline has self-cleaning ability, the construction simple and fast.
