Abstract
The present invention relates to a construction method for reinforcing foundations, which has the following steps: firstly, an outer casing tube is hammered into a foundation to specified depth; secondly, reinforcing materials are filled into the outer casing tube, the reinforcing materials are tamped by a rammer till the consistency of the tamped reinforcing materials satisfy the rammer retracting standard, and thus, the surface soil body of the foundation has maximum consistency, and the ground can not be bulged simultaneously; the outer sleeve pipe is lifted in identical height respectively to repeatedly carry out the second step, is filled with materials by layers and is tamped to the surface of the foundation, and thus, the consistency of materials of a compaction pile body and pile surrounding soil is kept to even.
Description
Technical field
The present invention relates to field of civil engineering, relate in particular to the consolidation process of ground.
Background technology
In the ground stabilization of building is handled, usually adopt dynamic compaction, but this method has the bigger shortcoming of vibration, so it is not suitable for constructing in the intensive city of building, notification number be disclose in the CN86200550U utility model patent document a kind of in ground by ramming the method that method forms ram-compaction gravel piles, in the method, pile monkey does not directly impact filler, but ram the rubble of being filled by the plug of core pipe and its bottom, the shortcoming of this method be to filler to ram energy less, particularly can not control every layer of compactness of ramming material, thereby the compactness that can not make pile shaft material and pile peripheral earth keeps evenly, it is stressed to give full play to the participation of pile shaft material and pile peripheral earth, and promptly the bearing capacity of formed composite foundation is less.
The content of invention
The object of the present invention is to provide a kind of job practices of consolidated subsoil, can form following composite foundation quickly and easily, in this composite foundation, keep evenly along the compactness of vertical compacted pile body and the compactness of all soil of stake by this method.
Above-mentioned purpose of the present invention is that the job practices by following consolidated subsoil realizes that this method comprises the steps:
A) outer tube is squeezed in the ground, until prescribed depth;
B) in this overcoat steel, fill reinforced material, adopt hammer ram that the reinforced material of being filled is rammed, compactness until the reinforced material of being tamped satisfies such ceasing driving standard, thereby the foundation surface soil body reaches maximum compactness, and the face of land does not produce protuberance simultaneously;
C) elevated height outer tube according to the rules carries out above-mentioned steps b);
D) with the elevated height outer tube of afore mentioned rules, carry out above-mentioned steps b repeatedly), carry out the layering filler and ram action, until the foundation surface place, thereby the compactness of compacted pile shaft material and the compactness of the soil body around this are kept evenly.
It is bigger that said method is adapted at water content, and be easy to generate in the foundation soil body of undergauge and construct.
Above-mentioned purpose of the present invention also can realize that by the job practices of following consolidated subsoil its step comprises:
A) adopt hammer ram that foundation surface is tamped, form the compaction pile hole;
B) to a certain amount of reinforced material of the inner filling in above-mentioned compaction pile hole, by above-mentioned hammer ram the reinforced material of being filled is rammed, compactness until the reinforced material of being tamped satisfies such ceasing driving standard, thereby the foundation surface soil body reaches maximum compactness, and the face of land does not produce protuberance simultaneously;
C) carry out step b) repeatedly, carry out the layering filler and ram action,, thereby the compactness of the material of compacted pile body own and the compactness of the soil body around this are kept evenly until the foundation surface place.
It is less that said method is adapted at water content, and can not produce in the foundation soil body of undergauge and construct.
In above-mentioned two kinds of methods, above-mentioned reinforced material adopts building waste.
In above-mentioned two kinds of methods, above-mentioned reinforced material adopts harsh concrete.
In above-mentioned two kinds of methods, above-mentioned reinforced material adopts the cement sand-lime.
In above-mentioned two kinds of methods, above-mentioned building waste is mashed watt an of brickbat, various discarded aggregates, cobble, slag, the compound of flyash or mentioned component.
The advantage of the job practices of consolidated subsoil of the present invention is that the vibration that produces is less, be particularly suitable for constructing in the intensive city of building, because it is stressed to give full play to the participation of pile shaft material and pile peripheral earth, can make composite foundation obtain higher capacity like this.
Job practices to consolidated subsoil of the present invention specifically describes with reference to the accompanying drawings.
Brief description of drawings
Fig. 1 is the concrete steps figure of the job practices of consolidated subsoil of the present invention.
The specific embodiment
The foundation soil body of constructing in the embodiment shown in fig. 1, is the soil body that is easy to generate undergauge.According to the job practices of consolidated subsoil of the present invention, as shown in Figure 1a, at first outer earthen-ware pipe 1 is sunk in the ground, until prescribed depth.The mode that sinks to outer tube 1 can be known variety of way, such as, hammering is with pipe method, vibratory drilling method or the like.Shown in Fig. 1 b, in above-mentioned outer tube 1, fill reinforced material 3, such as building waste, hammer ram 2 is moved along outer tube 1 reinforced material 3 of being filled is rammed, form the 1st compacted layer.Shown in Fig. 1 c, promote outer tube 1 specified altitude, according to the generation type of the 1st compacted layer, carry out filler, ram, thereby on the 1st compacted layer, form the 2nd compacted layer.Promote outer tube 1 according to above-mentioned specified altitude, fill reinforced material and the action of ramming by hammer ram 2 according to the generation type of the 1st compacted layer repeatedly, thereby form along stacked up and down a plurality of compacted layer, until the foundation surface place, thereby in ground, form and have erose compaction pile, shown in Fig. 1 d, why forming irregularly shapedly, is because each the compacted layer in the compaction pile is according to identical ceasing driving standard, controls such as pile penetration, consequently, around compaction pile, in the ground than the weak soil layer, clamp-oned more reinforced material, corresponding, the diameter of compaction pile herein is bigger, and in the ground than hardpan, clamp-on less reinforced material, corresponding, the diameter of compaction pile herein is less.That is to say, this compaction pile is along having identical compactness up and down, and pile peripheral earth also has identical compactness in addition, thereby the compacted pile shaft material and the stake soil body that can give full play in the formed composite foundation participate in stressed, promptly bear upper load, the bearing capacity of composite foundation is higher like this.
