Construction team for underwater wall removal by divers

1、 Introduction to the service of the construction labor team for underwater wall removal service:
Underwater crushing is a quick, safe and cost-effective scheme for underwater demolition of plugging walls. The underwater removal of the sealing wall requires a professional diving construction team. Experienced divers - our divers have long-term experience in underwater operations, and many sealing walls are removed every year. Our divers have professional engineering diving certificates issued by Shanghai Salvage Bureau, so that everyone can work with certificates

2、 Equipment required for underwater plug removal:
(1) Light diving equipment E300.
(2) One 0.35m3 air compressor.
(3) Two sets of underwater interphone systems.
(4) A bottle of medical oxygen.
(5) A set of underwater crushing equipment.
All personnel and equipment are provided by our company for labor and materials.
3、 Method statement for underwater blockage removal:
1. First, divers should conduct preliminary underwater exploration and visual inspection on the plugging wall piles to be removed to understand the site construction environment, especially how large the water level drop on both sides of the plugging wall is. The water level drop will form water pressure. Once the hole is broken, there will be suction. Divers should be careful to prevent being sucked.
2. The diving assistant shall prepare the diving equipment and underwater crushing equipment, and the diver shall break a small hole of about 10cm to balance the water level on both sides of the plugging wall when reaching the operating position. At this time, divers can leave the water to rest and wait for the water level on both sides of the plugging wall to balance.
3. After the water level on both sides of the plugging wall is balanced, the divers begin to remove the entire plugging wall, and try to select the connection of two bricks to remove in a time-saving and labor-saving manner.
4. After dismantling, the diver will put the broken bricks into the woven bag and notify the personnel on the water to lift them out of the well bottom.

5. Arrange the on-site equipment and clean it.
1. Our company's underwater unblocking construction teams are teachers who have hundreds of times of experience in plugging. They have rich experience in underwater unblocking and can serve underwater plugging environments with various difficulties.
2. Diving is a high-risk occupation, and what we are engaged in is also diving engineering. And it has always been and will be. There are many elements that constitute diving risks. Finding out the risk source is conducive to reducing or avoiding risks, thus improving life safety and laying a solid foundation for the company's development.
3. Underwater operation is a kind of work with high technical content, and the visibility in turbid water is zero. To complete the plugging task in this environment, the requirements for divers are quite high. At the end of each dive, the safety officer should check and repair the equipment to ensure that the equipment is in good condition. Before diving, the diver should check the equipment again in person to ensure that it is correct before diving.
