Abstract
The invention aims to provide a construction method for a concrete pile. Concrete pile with higher bearing capacity can be manufactured at a lower cost in harder sand layer foundation through the construction method to meet the requirements of buildings having higher demand on bearing capacity; the construction method comprises the steps of: 1) drilling holes at the pile position in the foundation by a helical drilling rod until reaching the designed depth; 2) lifting the helical drilling rod up, and pressing and filling mortar into the pile holes at the same time until pressing and filling mortar into the top of the piles; 3) drilling holes again by the helical drilling rod until reaching the designed depth; and 4) constructing the pile body.
Description
Technical field
The present invention relates to the construction technology of foundation, particularly relate to the construction technology of concrete pile.
Background technology
In the ground of building is processed, often run into such situation, under earth's surface there is the layer of sand that density is larger in certain depth place, and the water content of layer of sand is uneven, the uneven thickness of layer of sand.The pile body pore-forming of this geological conditions during to pile foundation construction causes great difficulty, and when particularly low, the thickness of the water content when layer of sand is larger, the conventional modes such as vibration sinking tube, static pressure or heavy tamping, are all difficult to form a hole substantially to projected depth at present.Even very difficult formation the stake hole of certain depth, after proposing outer tube or casing, the chiltern of hole wall all can form and cave in, and a hole is stopped up again.And if above-mentioned geological conditions adopts the method for manually digging hole limit, limit retaining wall, its construction costs again can be very expensive.Building major part is now all highrise building, more and more higher to the requirement for bearing capacity of pile foundation, and limited due to hole forming method of above-mentioned several construction technology has been difficult to applicable in above-mentioned geological conditions.Therefore, people are desirable to provide a kind of these needs that meet, and cost is the construction technology of lower stake still.
Summary of the invention
The present invention proposes in order to solve the above problems, object is to provide a kind of job practices of concrete pile, by this job practices, can in harder sand-layer foundation, with lower cost, make the higher concrete pile of bearing capacity, to meet the requirement of the building that requirement for bearing capacity is higher.
To achieve these goals, the job practices of concrete pile of the present invention comprises the steps:
1) place, stake position in ground, holes until projected depth by auger stem;
2) above-mentioned auger stem is upwards proposed on one side, to stake hole in press filling mortar on one side, until place, stake top;
3) again by auger stem, hole until projected depth;
4) carry out the construction of pile body.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 2), in, mortar forms with cement and sand and water mix.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 3), in, the diameter of auger stem is equal to or less than above-mentioned steps 1) in the diameter of auger stem.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 3) in, again by auger stem, hole, at mortar, tentatively solidify after possessing some strength and carry out.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 3) in, while again holing by auger stem, stake after auger boring is for the first time stopped up in hole when not serious, can substitute by the casing of with stake point being directly drowned in mortar to the mode of projected depth.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 4) in, the construction of pile body comprises by repeatedly filler and heavy tamping in stake hole, the stake end soil body reinforced compacted, makes the carrier of stake bottom.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 4) in, the construction of pile body is included in placement reinforcing cage in a hole, and forms pile body after pouring into a mould vibrated concrete.
Best, in the job practices of above-mentioned concrete pile, above-mentioned steps 4), in, the construction of pile body comprises precast pile is directly inserted in a hole, and concrete perfusion in the gap between preformed pile and stake hole.
The characteristics and advantages of the concrete pile forming by above method is: 1. pore-forming is simply rapid.Spiral draws the mode in hole can carry out rapidly pore-forming in harder layer of sand, after pore-forming, press again filling mortar to carry out retaining wall, even hole wall is also in the obstruction stake hole that caves in after retaining wall, by the time the water in mortar just provides some strength after being absorbed by surrounding soil, now again carry out spiral and draw hole, the intensity raising due to mortar, obviously improves than the effect of primary retaining wall, effectively avoided the obstruction of caving in of hole wall, the success rate of pore-forming and work efficiency are significantly improved.2. supporting capacity is high.The mode that spiral draws hole is convenient to form the stake that diameter is larger, and effectively after pore-forming, can at stake end, carry out the construction of carrier, give full play to foundation soil body participate in stressed, to improve bearing capacity of pile tip.Also can take directly to insert the mode of precast pile.3. with respect to methods such as manually digging holes, the advantage of the high and low cost of work efficiency is comparatively outstanding.
Accompanying drawing explanation
Fig. 1 has a process chart for the job practices of the concrete pile of the embodiment of end carrier as one of the present invention.
The specific embodiment
As one of the present invention, there is a job practices for the concrete pile of the embodiment of end carrier, it comprises the steps, first, as shown in Figure 1a, place, stake position in ground, by auger stem 1, hole to projected depth, then, as shown in Figure 1 b, above-mentioned auger stem 1 is upwards proposed on one side, in stake hole, press filling mortar 2 on one side, until place, stake top, then, as shown in Fig. 1 c, when mortar 2 tentatively solidifies while possessing some strength, again by auger stem 1 boring identical or slightly minor diameter, until projected depth, then, as shown in Figure 1 d, in stake hole, put into casing 3, in casing 3, insert a certain amount of prose style free from parallelism inserts 5, then, as shown in Fig. 1 e, the movement of falling object by weight 4 in casing 3, to the prose style free from parallelism inserts 5 of inserting, carry out compacted, then, as shown in Figure 1 f, repeatedly carry out filler and compacted operation, the certain depth of stake end below and the foundation soil body of scope are carried out to continuous ground extruding, until meet the requirement of compactness, then, as shown in Figure 1 g, to casing 3 bottom gradation, fill the harsh concrete 6 of scheduled volume and undertaken compacted by weight 4, then, as shown in Fig. 1 i, at the required concrete eight of the rear perfusion pile body of the interior placement reinforcing cage 7 of casing 3.Finally, as shown in Fig. 1 j, casing 3 is proposed, vibration compacting concrete eight.
