Ultimate Guides to Concrete Cement Silos: Safety Precautions
In this ultimate guide, we will explore the essential safety measures that must be implemented to ensure the safe operation of concrete cement silos.From identifying potential hazards to implementing best practices for maintenance and upkeep, this guide will equip you with the knowledge and tools you need to keep your silos and your workers safe.
Part 1: Safety assurance measures before installation
1.All workers and engineers should wear safety helmets before on-site operations.
2.On-site personnel and machinery must obey the deployment and command of the commander.
3.During the hoisting process, the crane movement must be stable, obey the command of the ground commander, and the hoisting operation of the crane must be commanded by a special person, and the operation must not violate regulations.
4.When hoisting, it must be fixed firmly to prevent decoupling. During the hoisting process, the staff shall not work under the hoisting objects.
5.Hoisting is prohibited in bad weather. Safety protection ropes must be equipped when working at heights. Hands should be firmly grasped when climbing. If the concrete cement silos is higher than other surrounding buildings, lightning rods should be installed.
6.When someone is operating on the upper part of the concrete cement silos, the construction personnel are required to fasten safety ropes and be equipped with relevant safety equipment, such as safety helmets, safety gloves, etc., to prevent construction accidents.
7.The verticality of the must be guaranteed when installing the concrete cement silos.
8.During installation, the installation size should be checked at any time, and adjustments can be made according to the actual situation to correct the deviation in time.
Part 2: Preparations before construction of cement tank foundation
1.Foundation axis dimensions, basement elevation and geology are checked.
2.Make flat marks on the concrete on the ground.
3.The steel bars, bolts and embedded parts buried in the foundation have all been installed.
Part 3: Pouring of Concrete
1.The height of the foundation concrete feed opening from the surface of the poured concrete shall not exceed 2m.
2.Concrete pouring should be carried out continuously in layers, generally the layer thickness is 1.25 times the length of the active part of the vibrator, and the maximum thickness does not exceed 50cm.
3.The grade of concrete used for pouring reserved pits should be one level higher than that used for the foundation. In winter construction, the concrete used should be added with early-strength antifreeze.
4.The plug-in vibrator should be inserted quickly and pulled out slowly, the insertion points should be evenly arranged, and the movement should be carried out point by point without omission, so that the vibration is compact and the movement distance is not greater than 1.5 times the radius of action of the vibrator. When vibrating the upper layer, the lower layer should be inserted 5cm to eliminate the seam between the two layers.
5.When pouring concrete, you should always pay attention to whether the formwork, bracket bolts, and embedded parts are moving. When deformation or displacement is found, the pouring should be stopped immediately, and the formwork should be repaired and strengthened in time. After complete treatment, continue to pour concrete.
6.After the concrete has been vibrated and compacted, the surface should be leveled.
7.Concrete maintenance: After the concrete is poured and smoothed, it should be covered and sprinkled with water in about 12 hours. The frequency of watering should be able to keep the concrete in a sufficient wet state. The maintenance period is generally not less than 7 days.
Part 4: Notes on foundation construction and installation
1.The ground screw bolt of the concrete cement silos is poured into the reserved pit of the foundation. While adjusting the center line of the concrete cement silos bracket to coincide with the center line of the foundation, adjust the four flanges above to be on the same horizontal plane (measurement method: theodolite or transparent plastic with a diameter of 8-10 Hose plus colored water measurement method), then can pour concrete.
2.After the concrete is solidified, When installing the concrete cement silos, it is necessary to measure the straightness of the concrete cement silos with a theodolite, and the straightness is one thousandth of the height.
3.During the installation process, be sure to put in the rubber strips and tighten the bolts. Install the cone part first, and each section of the bin body consists of 4 pieces. During the installation process, two pieces (leaving a vertical seam) are not bolted. Then connect the cone with the silo, and the vertical seams of the upper and lower parts cannot overlap. After the connection is completed, tighten the bolts on the remaining vertical seams of the silo. Install in sequence, each section of the silo can be replaced with each other, and finally install the upper cover.
4.Assemble the components of the supporting concrete cement silos one by one on the ground (install the upper and lower material level gauges and their circuits, dust collectors, ladders and railings, broken arches, cement feeding pipes, etc.), then lift the concrete cement silos and put it in place. Fasten the anchor bolts. (Note: For areas where the wind force is often greater than level 6 or above, a wind rope should be added).
5.Make sure that all the external threaded standard parts of the warehouse have been tightened. If the standard parts of the external thread of the warehouse are not tightened, the cylinder body will loosen, resulting in bending deformation and huge maintenance costs.
Part 5: Foundation Protection
1.It is necessary to ensure that the positions of steel bars, embedded parts, and embedded bolts are correct, and no collisions are allowed.
2.There must be no heavy objects impacting the formwork, and no scaffolding boards should be supported on the formwork of the hanging side to ensure the firmness and tightness of the formwork.
3.The side formwork should be disassembled when the strength of the concrete can ensure that its edges and corners will not be damaged.
4.Only when the strength of the poured concrete reaches 1.2MPa or more can walking and upper construction be carried out on it.
5.Settlement observation: Observe and record the settlement and verticality of the cement tank foundation every week. If the settlement or settlement is too large, release the cement in the tank and deal with it in time to avoid safety accidents.
Part 6: Regular cleaning of concrete cement silos
1.During cleaning only use a chisel. Avoid deformation or paint damage due to force. If you rinse for a long time, you need to use a cleaning agent to clean it, and clean it according to its cleaning standard, pay attention to the details of cleaning, and dry it immediately after cleaning.
2.The concrete cement silos dust removal equipment is related to the capacity of the cement tank, the discharge rate and other issues, especially the filter element of the dust collector. If it is damaged, it must be replaced in time.
3.After using the concrete cement silos for a long time, the dust contained in the silo body is easy to solidify and agglomerate. Once the material solidifies and agglomerates, an arch breaking device is required.
4.Regularly check whether the pipes and connections of the arch breaking device are loose or leaking, regularly check whether the electrical components are flexible and working normally, and whether the structure is damaged.
