Mass concrete modular elephant trunk construction device and method

Abstract

The invention discloses a mass concrete modular elephant trunk construction device and method.The mass concrete modular elephant trunk construction device comprises a steel pipe scaffold, a concrete elephant trunk channel is installed on the steel pipe scaffold, the concrete elephant trunk channel is formed by assembling a plurality of connecting pipelines, and a plurality of material collecting structures are connected to the concrete elephant trunk channel; the material collecting structure comprises a sleeve shell, a material collecting hopper, a top cover and a material distributing chute. The steel pipe scaffold is used as a supporting frame, the concrete elephant trunk channel is used as an elephant trunk, the material collecting structure is used as a buffering device and has the flow dividing function, the material distribution chute is used for increasing the pouring range, the concrete pouring efficiency is improved, the investment of people, materials and machines is reduced, and the construction cost is reduced; investment cost can be reduced, resource waste can be prevented, the purpose of adjusting the flowing resistance of the baffle to concrete can be achieved by adjusting the angle of the baffle through the arranged baffle, and destructive power generated by concrete flowing to a concrete chute channel is reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a large-volume concrete modular chute construction device and method. Background technique [0002] Mass concrete with a minimum geometric size of concrete structure not less than 1m, or concrete that is expected to cause harmful cracks due to temperature change and shrinkage caused by hydration of cementitious materials in concrete, is called mass concrete. The pouring of large-volume concrete rafts has always been a difficult point in construction, and the chute method is usually used for mass concrete construction, but the conventional chute construction uses steel pipes for chute support, which requires a huge one-time investment, and the steel pipes after concrete pouring are usually At the same time, when the concrete is poured using the chute, the flow rate of the concrete will become faster as the concrete is injected and flows down the chute, resulting in t...

[0002] Large-volume concrete whose minimum geometric dimension of the concrete structure is not less than 1m, or concrete that is expected to cause harmful cracks due to temperature changes and shrinkage caused by hydration of the cementitious material in the concrete, is called large-volume concrete, and the current narrow site The pouring of large-volume concrete rafts has always been a difficult point in construction. The slide pipe method is usually used for large-volume concrete construction, but the conventional slide pipe construction uses steel pipes for slide pipe support, which requires a huge one-time investment, and the steel pipes after concrete pouring are usually will be discarded, resulting in a waste of resources. At the same time, when the concrete is poured using the chute, as the concrete is injected and flows down the chute, the flow rate of the concrete will become faster, resulting in high-speed flow of concrete on the chute. Impact and cause damage to the chute
