Protection device for pile foundation blasting

Abstract

The invention discloses a protection device for pile foundation blasting. The device comprises a base, a connecting pipe and an anti-blasting net; a fixing frame is arranged at the upper end of the base, fastening screws are arranged at the upper end of the fixing frame, support legs are arranged at the lower end of the base, a protective skirt is arranged on the outer surface of the base, and a rubber pad is arranged at the lower end of the connecting pipe. According to the protection device for pile foundation blasting, an anti-rust plug, the protective skirt and the rubber pad are arranged,the phenomenon that connecting screws rust can be prevented, the service life of the equipment is prolonged indirectly, the damping, sound attenuation and connecting effects can be achieved through the connecting pipe, the protection device is firmer, the lower end of the protection device can prevent blasting through the protective skirt, the protection device is more effective, the whole protection device is tighter through the connecting screws, and the protection effect reaches the best state; by means of the rubber pad, the protection effect is increased, and the protection device is applicable to different work conditions and brings a better use prospect.

Description

technical field [0001] The invention relates to the protection field, in particular to a protection device for pile foundation blasting. Background technique [0002] Blast protection devices usually use shells, covers, screens, doors, covers, fences and closed devices as physical barriers to isolate people from danger. For example, protective boxes made of metal casting or metal plate welding are generally used for gear transmission Or the protection of the transmission device with a small transmission distance, the metal skeleton and the metal mesh are made of a protective net, which is often used for the protection of the belt transmission device. The fence type protection is suitable for occasions with a relatively large protection range or as on-site protection for temporary operations of mobile machinery. Fixed guards should be permanently fixed, fixed in place by means of welding, etc. or by means of fasteners such as screws, bolts and nuts, so that they cannot be mov...

AI Technical Summary

Problems solved by technology

[0003] The existing blasting protection devices have certain disadvantages when used. First, the fastening screws are prone to rust after long-term use, resulting in loose connections. Secondly, the vibration and sound generated by blasting cannot be reduced. It is very firm and cannot reach the best protection state, which has a certain impact on people's use process. Therefore, we propose a protection device for pile foundation blasting
