Before the latest hot product [covers safety nets] price is more? Where can I buy the municipal well anti-dropping 10:00 yesterday, Shenyang Five Love Street Style Road near the intersection of a manhole cover the cordon Weidang it. Cordon, four workers are installing anti-dropping network. Anti-dropping white, round, braided nylon rope, an area of ??approximately 1.5 square meters, consistent with the size of the manhole cover basic. Anti-dropping network center has a steel ring fall, braided core as a whole anti-green nylon rope weaving, nodules process after similar nets, woven into a circular network. The outermost of the network, a nylon rope as the side ropes, eventually fixed on the borehole wall. Construction workers to open the manhole cover, you can see that this is a depth of about 2 meters of the shaft. Construction workers protective rope, wear a helmet and other protective devices, sitting on the edge of the well, will head the probe into the wellhead, air drilling with drill in hand on the borehole wall. Installation of a safety net, an average of six holes drilled on the borehole wall, punch location away from the wellhead vertical distance of 30 cm. Punch, driven into the end of the galvanized hooked expansion bolts, tighten the fixing of the the green nylon prepared safety net hanging on the hook can be. Hung from the open manhole cover, to anti-dropping network, consuming nearly 30 minutes. After installation, construction workers jumped into the anti-dropping network acceptance. Drainage Management Office Chief Engineer Don East, the safety net will give priority to the installation depth of 2.5 meters above the manhole diameter of 1.2 meters above the the manhole tube rough, depth, once someone fall well, very dangerous. Reporter experience fall into the hook does not hurt when anti-dropping network installed 30 cm beneath the covers, slightly higher than the height of the step, the reporter just to leg forward, you have to focus the body are placed in the well only feet. Slightly falling 20-30 cm under the foot of the fence, in the crush of reporters, each knot is not misplaced. According to reports, this anti-dropping network can load 650 kg, the service life of 6-10 years. Reporter weight 75 kg, all two feet stepped on anti-dropping network, anti-dropping network is still intact. Around the wellbore week suspension screws between six arc-shaped air when each area of ??approximately A4 paper size. Visual reporter, even 1-2 years old baby should not fall into the air when. Suspension anti-dropping network expansion screws tail arc-shaped hook, hook substantially 360 degrees, close to the closed, it will not Gou Jian wounding. Sidewall are cement or brick, high strength, once someone fall into, you can take the pull of the anti-dropping network. In addition, after accidentally dropping network, the distance of 30 cm to just adult men at the knee, will not cause excessive startle people. Municipal wells anti-dropping network?

Anti- dropping network? communications well protective net anti-dropping network? tap water wells protective net? the inspection wells defense Hebei Five Star Electric Equipment Co., Ltd. is a research, development, production, sales in one of the science and technology company, is the core of the covers safety net products of Hebei Province enterprises. Company to introduce a number of advanced production and testing equipment, all production lines used in all automated production, to meet the requirements of the users of various models. North Star Electric Equipment Co., Ltd. developed the first successful in our country for municipal wells, wells of power, communications, wells, water wells, inspection wells, gas wells bilge wells special covers safety net covers anti-dropping network covers protective safety net --- grille and fixed hook grille consists of a number of nylon rope woven was cobwebs structure, installation is quick and convenient. At present, this safety net has been widely adopted. Introduction of Hebei Five Star subsurface well safety net expansion screw hooks Hebei Five Star subsurface well safety net expansion screw hooks fixed principle: Hebei Five Star underground wells protective net expansion screw fixed is the use of pull out of the hook-shaped slope to promote the expansion friction bond strength, fixed results. A screw thread, a vertebral degree. Wrapped in a layer of casing, casing cylinder half of the number of incision, put them together thiophene drilled holes into the wall, and then lock the nut, the nut of the screw pull it out, the degree of vertebral pulled into the cylindrical sleeve, round cylinder sleeve open up so tightly fixed to the wall, generally used for fastening of the fence, awning, air conditioning in the cement, bricks and other materials. Hebei five-star underground wells safety net expansion screw hook the principle of expansion bolts expansion bolts hit the hole on the ground or wall with a wrench to tighten the expansion bolt nuts, bolts, go out, and the outer metal sleeve does not move, the bolt under the bulk put metal sets up open throughout the hole, making it swell At this point, the of underground wells safety net expansion screw hooks expansion bolts pumping out. 1, dedicated expansion screw hook punch Depth: Hebei star underground wells safety net than the length of the expansion tube about 5 mm deep. As long as you is greater than or equal to the length of the expansion pipe, then left in the ground expansion bolt length equal to or less than the length of the expansion pipe. 2 underground wells in Hebei Five-Star safety net expansion screw hooks on the ground, of course the harder the better, it also depends on the objects you need to fixed the force. Installed in concrete or brick can be, Hebei Five-Star the subterranean wells safety net expansion screw hook properly installed in concrete or brick, an M8 expansion bolts, the underground wells protective network expansion screw hooks still subject to force is about 510 kg of municipal wells anti-dropping network? electricity well safety net? communication well safety nets? tap water wells protective net? inspection wells anti-dropping network? gas wells anti-dropping network? sewage wells protective network? municipal wells protective network? electricity well against network? anti-dropping network? communication well protective net anti-dropping network? safety net of water wells? inspection wells anti Hebei Five Star Electric Equipment Co., municipal wells protective net anti-dropping network, the electricity well protective net anti-dropping network, communications well protection network anti-dropping network, water wells protective net anti-dropping network, manholes safety net anti-dropping network, gas wells protective net anti-dropping network sewage wells protective network of anti-dropping network covers safety net sewer manhole anti-fall safety net, specifically the following advantages: 1, take high-quality nylon rope making, the single rope breaking force of up to 650 kg; 2, mesh fine and uniform, and the knot will not traverse back and forth, even if the children fall in, you can ensure safety can be customized according to different wellhead shape , so that the amount of the well system network; 4, acid and alkali resistant, not afraid of moisture, the service life of up to 6-10 years; 5, easy to install, easy to use. Off the future construction installation, convenient and quick; 6, waterworks, municipal municipal, electricity, hydro. Netcom gas water sewage so many users actually used to good effect, there has never been any quality problems. Hebei Five Star Electric Equipment Co., Ltd. anti-dropping network generally by hand weaving, one day can be made available to more than 100. Material is selected high-strength nylon rope, anti-corrosion. Online 8 hook, with an electric drill can be installed on the inner wall of the well drilling at 10 cm from the ground. Nylon mesh tightly wrapped around the hook, and folding several layers to increase the safety factor.
