Description
Technical field
The present invention relates to a kind of mesopore to catchment shaped pile, its circular hole mould adopted and construction technology thereof.Be applicable to treatment of soft foundation field.
Background technology
If ground is firm not before building, for preventing the accidents such as building groundwork sinking drawing crack causes building unstable, need to process subgrade, its sedimentation is made to become enough firm, the degree of consolidation of raising subgrade and stability are to the requirement designed, this process is called treatment of soft foundation, is soft foundation processing again.
Engineering method and feature thereof are commonly used in treatment of soft foundation:
1, compound foundation method: cement mixing method, powder spray piling, broken stone pile etc.; Shortcoming: cost is higher.
2, consolidation:
(1) plastic draining board combined stack-load: long in time limit, effect is undesirable
(2) plastic draining board combined vacuum precompressed: after 90 days durations, effect easily controls, and cost is low.
Summary of the invention
The technical problem to be solved in the present invention is: for above-mentioned Problems existing, provides that a kind of structure is simple, easy construction, lower-cost mesopore catchment shaped pile, its circular hole mould adopted and construction technology thereof, to improve the efficiency of construction of soft foundation treatment process.
The technical solution adopted in the present invention is: a kind of mesopore catchments shaped pile, it is characterized in that: have pile body, and pile body center is provided with concentric coaxial and at the gully-hole of pile body end face opening, described pile body is built by pervious concrete and formed with pile body.
The composition of described pervious concrete comprises cement, water and stone, cement: water: stone weight ratio is 1:0.3:5.6-6.
Described gully-hole is circular hole.
Described pile body is X-type stake or the stake of Y type.
A kind of circular hole mould, is characterized in that: this circular hole mould is used for described mesopore and catchments gully-hole shaping of shaped pile, and circular hole mould comprises and is rolled into by one piece of spring steel plate reel that cylinder formed and is placed in the support in reel, roll support being become cylinder.
Mesopore catchments the construction technology of shaped pile, it is characterized in that step is as follows:
1, stake mould is squeezed into stratum;
2, configuration reinforcement in stake mould, and the center in stake mould arranges circular hole mould according to claim 5;
3, between stake mould and circular hole mould, pervious concrete is poured into;
4, a mould is extracted after filling pervious concrete between stake mould and circular hole mould;
5, after pervious concrete solidification, extracted by the support in the middle of circular hole mould, wind-up drum under the effect of external force and reel its own resilient, reduces drum diameter, then extracts reel.
The invention has the beneficial effects as follows: the present invention adopts X-type stake or Y type stake pile body, uniform section periphery expands, and the comparable cylindrical, massive stake of pile body side surface area expands more than 1-2 times, and for the friction pile of power of rubbing based on side, cost greatly reduces.The present invention takes out hole (gully-hole) decrement at pile body center concrete, reduces material cost.Material of body of a pile adopts pervious concrete, after having built of pile body, water in the soil of pile body periphery waters through pervious concrete the pile body built up and collects in gully-hole, form draining well point, by dewatering installation, the water collected in gully-hole is discharged, contribute to accelerating foundation soil secondary consolidation, improve inter-pile soil bearing capacity of foundation soil, improve the efficiency of construction of soft foundation treatment process, reduce settlement after construction.In the present invention, gully-hole adopts the circular hole mould be made up of reel and support, and installation, convenient disassembly, provide efficiency of construction.

Detailed description of the invention
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of mesopore of the present embodiment catchments shaped pile, and have the pile body 1 of Y type stake, pile body 1 center is provided with circular gully-hole 11, this gully-hole coaxial arrangement concentric on pile body 1, and gully-hole 11 is at pile body 1 end face opening.
In this example, pile body 1 adopts pervious concrete to build to form, and the composition of this pervious concrete generally comprises cement, water and stone, cement: water: stone ratio is 1:0.3:5.6-6.Stone consumption is 1400 ~ 1600kg/m3.Cement amount wraps tightly stone with the cement paste of preparation, does not form slurry again, ensures that concrete permeable is as the criterion.The cement consumption of general non-fine concrete is 300 ~ 350kg/m3, and intensity is high suitable increase cement consumption again.
In the present embodiment, the catchment construction technology of shaped pile of mesopore is as follows:
1, utilize vibrating hammer that stake mould 4 is squeezed into stratum.
2, configuration reinforcement in stake mould 4, and the center in stake mould 4 arranges circular hole mould, sees Fig. 6.As shown in Figure 3, in this example, circular hole mould is made up of reel 2 and cross support 3, and wherein reel 2 (Fig. 4) is rolled into cylinder by one piece of spring steel plate and is formed, and reel 2 has the elasticity trend inwardly rolled tightly; Support 3 (Fig. 5) is placed in reel 2, supports reel 2, reel 2 is supported to the cylinder of pre-sizing.
3, between stake mould 4 and circular hole mould, pervious concrete is poured into.
4, vibrating hammer is utilized to be extracted by stake mould 4 after filling pervious concrete between stake mould 4 and circular hole mould.
5, after pervious concrete solidification, extracted by the support 3 in the middle of circular hole mould, wind-up drum 2 (see Fig. 7) under the effect of external force and reel 2 its own resilient, reduces reel 2 diameter, then extracts reel 2, completes mesopore and to catchment the construction of shaped pile.
Embodiment 2: the structure of the present embodiment is substantially the same manner as Example 1, difference is only that in the present embodiment, pile body 1 is X-type stake, sees Fig. 8.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned citing, those skilled in the art, within the scope of the invention, the change made, change add or replace, all should belong to protection scope of the present invention.
