Abstract
The utility model discloses novel hard-concrete-rubble dynamic compaction replacement single mound composite foundations which comprise a foundation trench. A single mound foundation layer is arranged in the foundation trench. A hard concrete layer is arranged on the single mound foundation layer. A cement mortar layer is arranged on the hard concrete layer. The novel hard-concrete-rubble dynamic compaction replacement single mound composite foundations have the advantages of improving bearing capacity of the single mound composite foundation remarkably, avoiding bulges and bottom diapirism of side face of the single mound composite foundation and reducing construction cost tremendously.
Description
Technical field
The utility model relates to a kind of building lot, especially relates to a kind of Novel dry rigid concrete-slabstone dynamic replacement list pier composite foundation.
Background technology
At present, in civil engineering, traffic engineering, in the processing of the soft foundation such as municipal engineering and hydraulic engineering, ground for single pier adopts heavy tamping replacement method usually, it namely mainly is stone filling in foundation ditch, the coarse granule such as rubble and jackstone discrete material, ram the continuous dynamic replacement list pier ground of formation with hammer ram, the amplitude that single pier bearing capacity of foundation soil of processing with existing these heavy tamping replacement methods improves is little, the side bulging and the single pier ground basal part that easily single pier ground occur pierce through destruction, and the ground that forms can not be directly as the post of superstructure or the basis of wall, not only cause huge economic loss, and stayed huge potential safety hazard to superstructure.
The utility model content
The purpose of this utility model is just in order to solve above-mentioned deficiency of the prior art, provide a kind of and can increase substantially single pier bearing capacity of foundation soil, the side of single pier ground avoids that also bulging occurs and pierce through the bottom, and a kind of Novel dry rigid concrete of great reducing construction cost-slabstone dynamic replacement list pier composite foundation.
The purpose of this utility model is achieved by following technical proposals: a kind of Novel dry rigid concrete-slabstone dynamic replacement list pier composite foundation, comprise foundation ditch, and be provided with single pier foundation layer in the described foundation ditch; Be provided with the harsh concrete layer above described single pier foundation layer, be provided with cement sand bed above the described harsh concrete layer.
Described single pier foundation layer is that harsh concrete and slabstone mix formation.
Described slabstone is large diameter block of stone or jackstone a kind of formation wherein.
The beneficial effects of the utility model are: adopt three layer construction to consist of single pier composite foundation, its basal layer adopts harsh concrete and slabstone to mix formation, not only can improve the bearing capacity of ground, can also greatly save engineering cost, the harsh concrete layer and the cement sand bed that on basal layer, arrange, played in its scope and to have reinforced and the effect of levelling, provide a firm basic platform for the post of superstructure or the basis of wall simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of Novel dry rigid concrete-slabstone dynamic replacement list pier composite foundation, comprise foundation ditch, be provided with single pier foundation layer 1 in the described foundation ditch, described single pier foundation layer 1 is that harsh concrete and slabstone mix formation, and described slabstone is large diameter block of stone or jackstone a kind of formation wherein; The utility model is provided with harsh concrete layer 2 on described single pier foundation layer 1, be provided with cement sand bed 3 above the described harsh concrete layer 2.
Job practices of the present utility model is:
(1) according to the superstructure load, carries out the calculation Design of harsh concrete match ratio;
(2) determine accurately that with transit each replaces the position of single pier, and make marks;
(3) harsh concrete and the slabstone for preparing mixed by a certain percentage, ram with dynamic compaction machinery and fill out in the bottom, and compacting;
(4) with tamping machine the harsh concrete rammer is filled out on the multiple top of dynamic replacement list pier, and compacting;
(5) dynamic replacement Dan Dun top reinforces dynamic replacement list pier along the top certain limit with cement mortar, and levelling, and straw mat is spread on top, carries out maintenance.
The utility model not only can be strengthened the bearing capacity on top self, and can provide a basic platform for the post of superstructure or the basis of wall.
Claims (3)
1. Novel dry rigid concrete-slabstone dynamic replacement list pier composite foundation comprises foundation ditch, it is characterized in that, is provided with single pier foundation layer in the described foundation ditch; Be provided with the harsh concrete layer above described single pier foundation layer, be provided with cement sand bed above the described harsh concrete layer.
2. require 1 described Novel dry rigid concrete-slabstone dynamic replacement list pier composite foundation according to brute force, it is characterized in that, described single pier foundation layer is that harsh concrete and slabstone mix formation.
