Abstract

The invention discloses an underwater rockfill concrete construction method, which belongs to the technical field of building construction. The present invention adopts block stones or pebbles with a particle size of more than 15cm, transports them to the surface of the underwater warehouse for natural accumulation by using ordinary transportation tools, and then puts a protective agent to protect the integrity of the underwater self-compacting concrete into the water, and uses the concrete that meets the requirements. The underwater special self-compacting concrete is poured naturally from the surface of the rockfill body with the help of a conduit, and the underwater special self-compacting concrete is used to fill the rockfill gap by its own weight, forming a dense and high-strength underwater rockfill concrete. The method is easy to construct, and has remarkable effects in improving construction efficiency and saving construction cost. The formed underwater rockfill concrete has less cement consumption, low hydration temperature rise, and has the advantages of energy saving and environmental protection.

Description

technical field

[0001] The invention belongs to the technical field of building construction, and in particular relates to an underwater rockfill concrete construction method. Background technique

[0002] With the maturity and development of self-compacting concrete technology, in recent years, a new rock-fill concrete (Rock Filled Concrete, RFC for short) dam construction method (Jin Feng, An Xuehui, Rock-Fill Concrete Dam Construction Method, Chinese Patent , Patent No. 03102674.5; An Xuehui, Jin Feng, riprap type rock-fill concrete construction method, Chinese patent, patent No. 200710121791.3; Jin Feng, An Xuehui, ordinary rock-fill concrete construction method, Chinese patent, patent No. 200710100315.3) has started get applied. Rockfill concrete uses self-compacting concrete instead of high-flow mortar, puts rockfill with a certain particle size directly into the warehouse to form a rockfill body with gaps, and then pours self-compacting concrete from the upper part o...
