The application of reinforcement can stabilize and limit the displacement of civil engineering during long-term use, and can transfer or distribute local stress acting on the soil to a larger area, increasing the frictional resistance between soil and geotextile. .
Rising Blocker also called Road Blocker , Gate Barrier ,block roads,car block,road Blocker system,automatic road blocker,Security Road Blocker,traffic spikes and Road Blockers,rising road blocker,portable road blocker,Hydraulic Road Blocker specification,car park blocker,road blocker installation manual,road blocker specification,hydraulic road blocker,roadblocker,road blocker.
The main functions of geotextiles are:
1. The application of reinforcement can stabilize and limit the displacement of civil engineering during long-term use, and can transfer or distribute local stress acting on the soil to a larger area, increasing the relationship between soil and geotextile. Frictional resistance.
2. Application of isolation The geotextile is used to separate different soil structures to form a stable interface, so that the layers are separated, and their respective characteristics and overall functions are exerted according to requirements.
3. Application of protection The geotextile can protect and prevent the impact on the soil or water surface.
4. Application of filtration The geotextile can pass the water and effectively prevent the passage of soil particles, thus preventing the loss of soil and causing the destruction of the soil.
5. Application of drainage The non-woven geotextile can form a drainage channel in the soil, collect the water in the soil, and discharge it along the plane of the material.
6. Application of anti-seepage effect Geomembrane and composite geotechnical materials, http:// can prevent liquid leakage, volatilization of gas, and protect the environment or building safety.
Main application areas of geotextiles:
Water conservancy projects: seawall, river embankment, lake embankment standard project; reservoir reinforcement project; cofferdam project; flood control and rescue.
Highway and railway airport engineering: soft foundation reinforcement treatment; slope protection; pavement anti-reflection crack structure layer; drainage system; green belt.
Electrical engineering: nuclear power plant foundation project; thermal power ash dam project; hydropower station project.

Hydraulic Rising Road blockers General Description Road blockers are designed especially for entrance points which have a threat of vehicle attack or for the ones that have high security requirements. If there is a threat of vehicle attack in addition to the control of vehicle access in high security applications, hydraulic road blockers are the unique solution and the most secure systems. Even though the attack is from high tonnage vehicles with high speeds, it's not possible for the vehicle to keep on moving because of the damage given to front, wheels and the bottom of the vehicle. RS Security Co.,Ltd road blockers are designed to K12 standards. Finite element model analyses are available upon request. Drive unit is electro-hydraulic, but in case of power failure road blocker can be lowered or lifted manually with the help of hand pump. Typical raise/lower time is 3 seconds. In case of emergency, raise/lower time can be as low as 1.5 seconds. With the help of PLC (programmable logic control), raise/lower function can be achieved by every kind of card readers, biometric readers like fingerprint or hand shape, radio control, on/off key switch etc. Besides, safety accessories like photocells, inductive loop detectors, flashing lights or red/green traffic lights can be integrated to the system very easily. Typical weight of a road blocker is 2-2.5 tons (depending on road blocker type).
