Owing to city planting ductwork hydraulic pressure can not meet the construction water of Highrise buildings, and flow and the water level in pipe network do not reach working-yard required water amount, therefore contiguous in working-yard increases tank and pressure pump, to reach the order ground of high-building construction water.
According to on-site actual situations, rationally arranging tank position and install pressure pump, pond is about the volume of 10m3, it is possible to meet site operation water and interim fire-fighting water yield 25L/S. Once presence of fire, start water-engine and pressurize, make the flow in pipe network and hydraulic pressure reach fire-fighting requirements.
Water facilities 7 can be specifically pressure pump, and the water outlet at pressure pump increases rubber soft-jointing head, prevents equipment from rotating to tubing system because of vibration.
One, water consumption: 25L/S considers
Two, the determination of water path tube
D=[4Q��(3.14��V��1000)]1/2
Wherein: D caliber (m);
Q water consumption (L/s);
Flow velocity (generally getting 2.0��2.5m/s) in V pipe network
Therefore the choice of diameter 100mm water supply steel tube.
Three, the calculating of pump head:
Pump head calculation formula is as follows:
H=H1+H2+H3
H is pump head (rice)
H1 is that water pump suction pipe arrives and the most unfavorable selects the discrepancy in elevation (rice)
H2 is pipeline head loss (rice), calculates by the 10% of H1
H3 is not for the most to utilize water spot water outlet hydraulic pressure (rice)
Difference according to engineering height, it is possible to arrange described scaffolding be raising legs or for landing, overhanging scaffold.
Scheme one (high level): carry out according to scaffolding scheme, scaffolding scheme adopts outer raising legs to set up, by 6 layers of consideration. The system sub tube installation of drenching with rain is raising legs one layer of bottom, triple bottom portion, five layers of bottom, six layers of top.

Note can not slot rolling too fast, otherwise pipeline and zinc coating can be damaged; Can not slot rolling too dark, need to by the spacing control of setting, to prevent affecting the intensity of pipeline;
In the process of slot rolling, pipeline to be kept level, strictly prevents pipeline from longitudinal displacement and angular travel occur. When destructive crack occurs in the position of groove processing, this part should be cut away and again process groove.
If the surface crack occurred, when confirming not affect intensity after metal defect detection, just can install after this position is carried out rotproofing.
The cracking of the plating layer inside and outside pipe found in processing groove, scaling damage, this is relevant with pipe material, galvanizing quality and slot rolling speed etc.
When there is this kind of situation in local, it is possible to occurring that position spraying red lead twice spray zinc process again.
In installation, the chimb of groove type pipe should stick into behind the position of groove holding bolt again, and the bolt on both sides should be simultaneously fastening. The airtight circle of rubber should without damaged and distortion, if fastening time find that rubber is airtight and enclose the rubber circle wrinkling and should more renewing. Strictly prop up/suspension bracket by strictly regulating to arrange fixing/suspension bracket or slide.
Pipe support be in tubing system install major issue it. Adopting the feedwater piping that groove pipeline connects, (frame system not only wants supporting pipeline weight, also to be born hydraulic pressure under pipeline pressure test and working order, the axial force of temperature variation generation and displacement for it.The pressure of system itself is just bigger, and the pressure finally acted on support is very big. The Bracket setting that groove connects should meet the following requirements: standpipe 1 support (pipe clamp), when floor height is not more than 5m, must install 1 support for every layer; When the big sub-5m of floor height, every layer is no less than 2 supports. The spacing hanging (holder) frame 2 suspension brackets on each straight line pipeline section on transverse tube should be less than the requirement of specification.
It is important to note that, system should be provided with enough fixing supports. Its main positions be the bottom into water standpipe 1, standpipe 1 pick out the accessory position of arm, standpipe 1 needs supported weight because free length is longer position, transverse tube pick out arm and be connected with branch pipe connection and accessory position, need the positions such as control pipeline extension.
