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

specific Embodiment approach

[0018] Step 1: Mixing of concrete: The concrete used in the anhydrous underwater concrete pouring method has specific requirements. The concrete mix ratio should adopt the mix ratio of underwater concrete. The mix ratio of C30 concrete is: water (164kg): cement (320kg ): gravel (1047kg): sand (790kg): water reducing agent (3.6kg): fly ash (80kg). The design slump of concrete is 180~220mm.

[0019] Step 2: Kick-off: When the first set of concrete is poured, the distance between the conduit opening and the bottom of the hole is 40~50cm. The kick-off does not need to consider the buried depth of the conduit. It only requires continuous supply of concrete to ensure that the surface concrete is not in the initial setting state, such as figure 1 shown.

[0020] Step 3: Pouring buried depth control: The pile body concrete of the anhydrous underwater concrete pouring method is mainly achieved through the self-weight and downward force of the concrete to achieve compaction. The buried...

Abstract

The invention discloses a method applicable to pouring of concrete for an artificial excavating pile body. The method is characterized by comprising the following steps: (1) mixing of concrete; (2) start of pouring; (3) control on pouring buried depth; (4) conversion between no vibration and vibration, and (5) pile head pouring processing. Compared with conventional rinsing pile pouring method and dry pile pouring method, the pouring method disclosed by the invention has the following advantages: 1. compared with a conventional dry pile pouring method, according to the anhydrous underwater concrete pouring method, layered pouring and vibration are not needed, and therefore, the risk of artificial under-hole operation is reduced, and the pouring efficiency is improved; 2. according to the anhydrous underwater concrete pouring method, water injection into the hole is not needed, the influence of high and cold drift beds with relatively great permeability is reduced, and the safety is improved; 3. according to the anhydrous underwater concrete pouring method, the visibility is relatively good and the quality is easy to guarantee; and 4. when the phenomena of pipe plugging and conduit exhaust occur during pouring, the quality accident of pile breakage cannot be caused.

Description

technical field [0001] The invention relates to the field of concrete pouring for pile bodies of manual-dug piles, in particular to a pouring method for realizing safe, efficient and quality-controllable concrete for manual-dug pile piles. 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 with better water retention. Compared with the dry pile pouring method, it has higher efficiency, fewer process changes, and doe...
