1. Main technical content and performance:
The tower crane sprinkler system refers to the water spray system preset through the tower crane's rotating arm after the tower crane is installed. The actual conditions of the construction site are pressurized by a pressure pump, or a water pump is installed in the third-level sedimentation tank underground at the construction site. The water is sent to the tower arm on the top of the tower crane through the water pump. The water is pressurized and sprayed through the nozzle to form a mist. , the drizzle falls evenly over most of the construction site with the help of the tower crane's boom rotation, achieving effects such as dust reduction.
The performance characteristics of this system:
Wide spray range, which can completely cover the area within the rotation radius of the tower crane. The tower crane rotates at an angle of 3 degrees during operation. Calculated in meters of spray radius, the tower crane circles the construction site. How many square meters does one revolution cover?
By spraying and spraying the construction site, a good dust reduction effect can be achieved, the construction site head can be suppressed, and pollution control and haze reduction can be achieved.
In hot weather, spraying and spraying are used to cool down the construction site and help workers survive the heat.
. Spraying and curing concrete within the spray range can save a lot of manpower and material resources.
, prevent and reduce fires.
The main components of the tower crane spray system are:
Water pump, water pump control system, filter, universal joint support frame, special universal joint for tower crane spray, adjustable nozzle, water pipe and water pipe accessories, etc. Specific material selection: According to the length of the tower crane's rotating arm, a nozzle is generally installed at a distance of 3 meters. The flow rate of the pump, the thickness of the water pipe and the model of the universal joint are determined according to the required flow rate of each nozzle. The lift of the pump is determined based on the height of the tower crane, and the pressure resistance of the water pipe must meet the on-site requirements.
1. Construction sequence
Leave construction fire-fighting pipe interfaces at the foundation of the tower crane in advance.
Before the tower crane spray installation, a preset sprinkler head should be spaced 3 meters apart according to the length of the tower crane's rotating arm.
Install the universal joint support frame according to the axis core of the tower crane universal wheel and set the universal joint of the spray system to maintain coaxiality and concentricity.
. Lay the rotating boom pipeline with pre-connected nozzles on the rotating boom and connect it to the universal joint.
, connect the water pipe and connect it to the universal joint.
, Debugging the tower crane spray system.
3. Construction Difficulties
The construction difficulties are the third item in the construction sequence, universal joint installation and pipe support system. Welding is strictly prohibited on the standard parts of the tower crane. The universal joint support frame is equipped with two top-pressure fixed supports. The universal joint support frame is fixed to the universal joint through screw buckles. The pipe support is connected to the standard joint using screw buckles. (One principle is not to affect the support system of the tower crane itself)
4. Maintenance of the spray system
Regularly check whether the pipe support system and the universal joint support frame have been displaced every week. Check whether the screws of the universal joint and universal joint support frame are loose.
5. Precautions
In order to ensure the quality of spray water, a reclaimed water treatment system can be added according to the actual situation.
.The location of the water pipeline should be set according to whether the tower crane needs to be raised
