Q: What are the advantages of hydraulic concrete placing boom?
A: 1) It is safe and efficient and improves economic benefits. Because of its large placing range and flexible and convenient operation, it does not require workers to constantly transport concrete or frequently dismantle and connect pipes like other pouring methods. Therefore, it reduces labor intensity and safety risks. At the same time, it greatly speeds up the process of concrete pouring, shortens the construction period and improves economic benefits.
2) It improves the quality of concrete construction. During the large-area concrete pouring process, it often takes a certain amount of time to pass through the hopper and frequently dismantle and connect pipes, which makes the concrete easy to lose water and affects the quality. However, the hydraulic placing boom can pour continuously, making the concrete easier to vibrate, with higher density, more uniform solidification shrinkage, and elimination of shrinkage cavities, cracks, segregation and other defects that affect the construction progress and construction quality.
3) It avoids hidden damage to the building structure. During the traditional pouring of concrete, due to the high pressure of the stationary concrete pump, the pipes vibrate on the surface of the platform. This vibration can easily leave hidden damage to the structure that is difficult to heal after the initial setting and before the final setting of the concrete. When using a concrete placing boom, it does not come into contact with the formwork, so it does not vibrate the formwork, which avoids damage to the building structure.
4) Wall pouring and platform formwork do not affect each other. When the grade requirements of wall and floor concrete are inconsistent, walls and columns are required to be poured first. At this time, because the platform formwork has not been erected, it is very difficult and unsafe to manually remove the pipes. However, if the pipes are connected after the platform formwork is set up, it will affect the construction period and is not conducive to the reasonable arrangement of the labor force. If a hydraulic concrete placing boom is used, the wall pouring and platform formwork do not interfere with each other, and the efficiency is particularly obvious.
Q: What are the precautions when using the hydraulic concrete placing boom?
A: 1) It is limited to transporting concrete (generally speaking, the density is about 2.2t/m³).
2) Φ125mm is the maximum diameter of concrete pipe, and larger diameters are not allowed.
3) The length of the hose at the end of the hydraulic placing boom shall not exceed 3m.
4) The hydraulic concrete placing boom must not be used as a crane to lift or drag items.
5) The allowable wind speed under working conditions shall not exceed 56Km/h. Under non-working conditions, the allowable wind speed shall not exceed 72Km/h.
6) After the work is completed and cleaning is completed, the placing boom should be folded and retracted with safety hook and turned in the direction of the wind.
7) In case of thunder and lightning, work should be stopped immediately.
