Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering construction, in particular to a supporting method of a reinforced concrete pressure relief cone. BACKGROUND

[0002] The reinforced concrete silo structure has a large volume, a large slope and is constructed at a high altitude, so the construction process is complex and the construction period is long. In the traditional cast-in-place concrete silo structure, after the construction of the silo wall sliding form is completed, the cast-in-place concrete cone in the silo or the method of pouring 2-3m of concrete at a time or the method of vertical prefabrication on site is adopted. These three pouring methods all need to leave a construction joint. Since the raw material particle size of the cement plant is at least 90μm, the construction joint needs to be treated if it is not prevented. Therefore, cold joints are easily generated in the concrete pouring, the construction period is prolonged, and the construction cost is increased.

[0003] In summary, the current construction of the pressure relief cone mainly has the following problems: using the traditional reinforced concrete structure with cast-in-place, since the shape of the cone shell is a conical surface, the size of the formwork and the length of the reinforcement along the height direction change, the construction process of the formwork engineering and the reinforcement engineering is complex and difficult, and it is time-consuming and labor-intensive; using the traditional reinforced concrete structure with prefabricated assembly, since the weight of each prefabricated component is large, the hoisting capacity of the hoisting equipment is required to be very high, and the use cost of the equipment is high; using the traditional reinforced concrete structure with prefabricated assembly, when the secondary pouring treatment is not performed between the prefabricated components, the overall structure and the sealing performance are relatively poor.
