The latest model of reinforced concrete deep tube
This applies to the well pipe inner diameter 300 ~ 500m, 500m deep depth within, can be widely used in underground water and agricultural irrigation chemical, textile, and food industry, in recent years, the product has been in Jiangsu, Zhejiang, Anhui, Shandong, Hebei , Shaanxi, Sichuan, Jiangxi and other places application. From 1969, the first thing out of the use of three wells has been well pipe production and application of these 2.5 million meters, as compared with the same quantity of steel, saving 230,000 tons of steel, saving 113 million yuan of funds; and the same number of cast iron pipe compared to saving 320,000 tons of pig iron, save money 138 million yuan; compared with the same size tube wells, saving 76% than the metal pipes funds and 93% of materials.
Reinforced concrete pipe deep well
From a practical look at the effect of this is good for the well pipe. 18 years, only construction machinery company in Jiangsu Province has become a hit at various depths of more than 1,400 deep tube wells of reinforced concrete eye, there are no supply problems in 1984 in Jiangsu Province, eastern Taiwan county Joan Harbour cannery hit 439 meters of steel concrete tube wells and nearly 400 meters deep pipe wells, the East Yellow Sea 5.1 earthquake test, the well pipe deformation can not be used, and reinforced concrete tube wells was left intact, still water. Therefore, this very well pipe promotional value. Reinforced concrete tube wells divided wall pipe and two kinds of water treatment. Constructed and reinforced concrete water pipe almost. The difference is, at both ends of the tubes are welded to each other for the use of flat hoop addition, drainage pipes along the wall with a row of circular drainage port tube outsourcing copper mesh, wire mesh, nylon and other facilities to prevent sediment .
Reinforced concrete wall pipes and drainage pipes are reinforced, depending on size requirements. With a special automatic seam welding machine made skeleton. If the filter pipe will lead weights with 20 # lead wire tied on the frame, and then pouring. Pouring using centrifuge tube wells, sub-slow (speed of 100 rev / min for 1 to 2 minutes), medium (200 to 280 rev / min, 1 minute), fast (400 rev / min, 5 to 8 minutes ) third gear speed is completed.
After the initial well pipe is made, to improve conservation, first raised 40 ~ 50 ℃, 30 ~ 40 minutes; then heated 50 ~ 60 ℃, 30 ~ 40 minutes, then heated 60 ~ 90 ℃, 30 ~ 40 minutes. Total steam curing time of 90 to 120 minutes to extend the winter thermostat 30 to 40 minutes. After centrifugation stripping strength of concrete steam curing, usually around 150kg / cm2, after the release of water through the second support (deep well of about 18 ℃, about 14 days), and then out of the pool or wire-wrapped stack is finished.
Reinforced concrete risers as the main raw material of steel: A: Low-carbon cold drawn steel wire; cement: 425 ~ 525 slag or ordinary Portland cement; sand: The sand coarse, continuous grading, clay content control in about 1%; stones : melon seeds, clay content control in about 1%; concrete mix: 1: 1.38: 2.22: 0.45 to 0.5; Mixture slump: 5 ~ 6CM; risers concrete grade: 400 #.
This is such a well pipe construction and installation. Before lifting the tube end 10 ~ 12mm welded steel circle, lifting jig for positioning. Jig should be slightly larger than the outer diameter of the port flat metal straps to prevent damage to the ends of the tube. When installing tube wells, set up two vertical tripod, two-way positioning action to ensure verticality. Between the well pipe, welded connections.
When relatively deep tube wells installed in the tube located at the head of the buoyancy device, so that the tube is formed of a barrel mouth down to the buoyancy of water to reduce the weight of the tube. At the same time pay attention to the construction of "light lift at slow", all tubes installed, temporarily decoupling, so that in a semi-state of weightlessness, then backfill the pipe four weeks so that even by force, until sealed. Raymond then hanging rope, break buoyancy tube, a tube cleaning sediment can be delivered.
