Note pouring concrete fabric of job   

Pouring concrete fabric should send someone to the job template frequently observed reinforcement, reserved holes, embedded parts, dowels, etc. Have displacement deformation or blockage, identify problems and should be watered Diesel concrete pump immediately and should have been trimmed before the completion of the initial setting of concrete pouring . After pouring is completed, check whether the steel surface or contaminated concrete placing boom, and timely cleaned. Concrete placing boom segments should be concrete with stratified, each pouring height should be determined according to the structural characteristics and reinforced density conditions. Vibrators generally stratification height is 1.25 times the length of the active portion, the maximum does not exceed 500 mm; layer thickness of the plate vibrator is 200mm. Then, use vibrators should be done slowly push pull, plug point to be evenly, point by point move, according to the order can not be missed, so that even the tap. Fabric machine moving spaced not more than 1.5 times the radius of action vibrator (typically 300 ~ 400 mm), close to the template distance of not less than 200 mm. The vibrator should be inserted into the lower layer of the concrete surface 50 ~ 100 mm, in order to eliminate the seam between the two layers. Moving pitch plate vibrator should guarantee cover plate vibrator has tapped part edges. It should also be pouring concrete should be carried out continuously. If it is necessary intermittent, intermittent time it should be as short as possible and should be before the initial setting of the first layer of concrete, the sub-layer of concrete pouring is completed. The maximum time interval should be all the initial setting of cement and concrete conditions to determine the general more than two hours should be construction joint.

Fabric machine and concrete pump with

During the construction of the building, the fabric machine, concrete pumps and booms with the use of the process to ensure that the scope of some of the requirements for concrete pouring and thickness. In the concrete pouring of the requirements are: 1. concrete bucket mouth from falling freely pour down height must not exceed 2m, measures must be taken when such exceed 2 m. Should string tube, a catheter, or chute opened the door in the side of the hole template (green port). 2. pouring concrete should be stratified segments, each pouring height should be determined according to the structural characteristics and reinforced density conditions. Vibrators generally stratification height is 1.25 times the length of the active portion, the maximum does not exceed 500 mm; layer thickness of the plate vibrator is 200 mm. 3. concrete placing booms for sale actuated vibrator, vibrators hand holding the upper end of the shaft vibrator hose, quickly insert inside the concrete, when vibrators, vibrator up and down a slight twitch, vibration time is 20 to 30 seconds, but no concrete surface bubbles, no significant subsidence, surface and the surface of the horizontal pan-pulp prevail. Use vibrators should be done slowly push pull, plug point to be evenly, point by point move, according to the order can not be missed, so that even the tap.

    

Mobile spaced not more than 1.5 times the radius of action vibrator (typically 300 ~ 400 mm), close to the template distance of not less than 200 mm. The vibrator should be inserted into the lower layer of the concrete surface 50 ~ 100 mm, in order to eliminate the seam between the two layers. Moving pitch plate vibrator should guarantee cover plate vibrator has tapped part edges. The pouring of concrete should be carried out continuously. If it is necessary intermittent, intermittent time it should be as short as possible and should be before the initial setting of the first layer of concrete, the sub-layer of concrete pouring is completed. The maximum time interval should be all the initial setting of cement and concrete conditions to determine the general more than two hours should be construction joint. 5. send someone should be pouring steel template frequently observed, reserved holes, embedded parts, dowels, etc. Have displacement deformation or blockage, identify problems and should be watered immediately trimmed completed before the initial setting of concrete has been poured. 6. When finished pouring, check whether the reinforced concrete surface contamination, and promptly cleaned. Just after the above-mentioned requirements to operate can guarantee quality boom pouring concrete.
