Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As shown in Figure 1, the invention provides a kind of Triangular Flos Mume shape drilled pile, comprise pile body 10, described pile body 10 forms by the pile body 11 of three distributions triangular in shape is bonded to each other.It should be noted that, pile body 11 is fitted bonded to each other by pile lining or pile body, and be not fitted by the end of pile body 11, three pile bodies 11 rear formation petal-shaped structure bonded to each other, especially as Triangular Flos Mume shape.In order to improve bending resistance degree and the structural strength of pile body 11, reinforcing cage 20 is also provided with in pile body 11, the shape of reinforcing cage 20 cross section is identical with the shape of pile body 10 cross section, and the size of reinforcing cage 20 cross section is less than the size of pile body 10 cross section thus makes reinforcing cage 20 can be placed in pile body 10, reinforcing cage is made up of longitudinal reinforcement 21 and steel hoop 22, wherein longitudinal reinforcement 21 is parallel to each other and is erected in pile body 10, and steel hoop 22 is fixedly connected with longitudinal reinforcement 21 thus forms the reinforcing cage 20 of cage.
In the present embodiment, can be understood as: when pile body 11 is not overlapping, the cross section of every pile body 11 is circular.Again shown in composition graphs 2 and Fig. 4, wherein every pile body 11 overlaps with other two pile bodies 11, and the center of circle distribution triangular in shape of the cross section of three pile bodies 11.The cross sectional area of every pile body 11 is identical or not identical.Wherein a pile body 11 is equal or unequal with the cross sectional area of other two pile body 11 laps.
As shown in Figure 3, pile body 10 is provided with the expansion section 30 that at least one protrudes pile body 10 outer wall.Expansion section 30 is interconnected by the pile body protuberance 31 that three protrude each pile body 11 outer wall respectively and forms, and the external surface of pile body protuberance 31 is circular arc, and specifically, pile body protuberance 31 is outstanding along pile body 11 radial direction, and the line of ledge is circular arc.Preferably, there is two or more expansion section 30 and along the axially-aligned of pile body 10, more preferably, when expansion section 30 is multiple, the spacing between every two expansion sections 30 is identical.
Present invention also offers a kind of manufacturing process of Triangular Flos Mume shape drilled pile, comprise the following steps: A, borehole, dig out the cylindrical hole of 3 distributions triangular in shape in the earth formation, and three cylindrical hole formation stake holes bonded to each other;
B, grouting, pour into for shaping cement paste or mortar in stake holes, and make the top of cement paste or mortar and stake holes have space;
C, in stake holes, put into reinforcing cage, continue to pour into cement paste or mortar, after coagulation forming, be drilled pile.
Preferred version, in step, casing is squeezed in advance in soil layer, casing submergence depth is through covering layer, borehole adopts three axle rigs, by three of rig auger spindles by rounded projections arranged, three auger spindles form three cylindrical holes of Triangle-Profile from ground toward underground drilling simultaneously, and the drill bit that described auger spindle is installed is the adjustable reaming bit of the radius of gyration; In stepb, the height pouring into cement paste or mortar is the 1/3-2/3 of the stake holes degree of depth, and in filling process, casing rises along with the height of cement paste or mortar and progressively upwards promotes; In step C, the shape of reinforcing cage but size identical with the shape of stake holes is less than the size of stake holes.
Specifically; in borehole step; the casing conformed to drilled pile profile is first squeezed into severely-weathered layer as guide pile by survey crew; the size of this casing should be more than or equal to the size of drilled pile; the key of boring success or failure prevents hole wall collapse; when holing darker; hole wall soil below groundwater table can cave in, even quicksand phenomenon occur under hydrostatic pressure in hole; casing plays the effect preventing hole wall collapse, isolates the effects such as surface water, protection ground, aperture, spud pile hole site and drill bit guiding in addition simultaneously.The material making casing has wood, steel, steel concrete three kinds.Casing requires sturdy and durable, water-tight, and its internal diameter should be larger than bore diameter.
Boring adopts normal circulation slewing drilling machine to enter construction technology, suitably earth is thrown less at clay layer, pulping is voluntarily crept into by auger spindle, concentration of hydraulic mixture Gu Bi is then strengthened at sandy soils, three auger spindle rate of penetrations adapt with mud discharge rate all the time, when meeting scall, suitably increase specific gravity of mud and denseness, alleviate as far as possible and rush the impact of liquid on hole wall, reduction rotating speed and the pressure of the drill are to meet quality control on construction requirement simultaneously.
Reinforcing cage needs prefabricated in advance, in borehole process, as run into the good geological stratification of soil property, reaming bit should expand the radius of gyration thus form the hollow part protruding pile body, when making grouting, cement paste can be circulated in hollow part and form expansion section 30, improves uplift resistance and the bearing capacity of pile body 10.Easy construction simultaneously, substantially increases the speed of stake processed.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ the terms such as pile body 10, pile body 11, reinforcing cage 20, expansion section 30, pile body protuberance 31 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
