Pouring method of manual digging pile body concrete by using anhydrous underwater concrete pouring method

Abstract

The invention discloses a pouring method of manual digging pile body concrete by using an anhydrous underwater concrete pouring method. The pouring method of the manual digging pile body concrete by using the anhydrous underwater concrete pouring method is characterized in that the pouring method comprises the following steps of (1) concrete mixing, (2) start of pouring, (3) pouring deep buried control, (4) transformation between vibration-free tamping and vibration tamping and (5) pile head pouring treatment. Compared with a traditional clear water pile pouring method and a dry pile pouring method, the pouring method has the advantages that 1, compared with the traditional dry pile pouring method, the anhydrous underwater concrete pouring method does not require layered pouring and vibration tamping, the risk of artificial operation under a hole is reduced, and the pouring efficiency is improved; 2, compared with the traditional clear water pile pouring method, the anhydrous underwater concrete pouring method does not require to inject water into the hole, the influence on surrounding holes is reduced with a large permeability moraine layer, and the safety is improved; and 3, thevisibility of the anhydrous underwater concrete pouring method is good, and the quality is easy to be guaranteed.

Description

technical field [0001] The invention relates to the field of concrete pouring for pile bodies of artificially digging piles, in particular to a method suitable for pouring concrete for pile bodies of artificially digging piles in moraine layers, that is, an anhydrous underwater concrete pouring method, which is safe, efficient, and reliable in quality. control. Background technique [0002] At present, domestic manual excavation piles are mostly poured by dry pile pouring method and clear water pile pouring method. Among them, dry pile pouring is suitable for strata with poor water retention. This method has the characteristics of good construction visibility, but its construction efficiency is low. The process changes frequently, the construction personnel work in the hole for a long time, and the safety risk is high, and the quality of the concrete pouring of the pile body is greatly affected by human factors. The clear-water pile pouring method is suitable for strata wit...

Problems solved by technology

[0002] At present, domestic manual excavation piles are mostly poured by dry pile pouring method and clear water pile pouring method. Among them, dry pile pouring is suitable for strata with poor water retention. This method has the characteristics of good construction visibility, but its construction efficiency is low. The process changes frequently, the construction personnel work in the hole for a long time, and the safety risk is high, and the quality of the concrete pouring of the pile body is greatly affected by human factors

The clear-water pile pouring method is suitable for strata with better water retention. Compared with the dry pile pouring method, it has higher efficiency, fewer process changes, and does not require construction personnel to work in the hole for a long time. However, this method has poor visibility and is prone to A series of construction problems such as pipe plugging, pipe emptying and backwater, etc., thus affecting the quality of the pile body
