Detailed description of the invention
Inventive feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, with
It is easy to the understanding of technical staff of the same trade:
Such as Fig. 1-6, in figure labelling 1-13 be respectively as follows: rig 1, drilling rod 2, stirring-head 3, soil cement enlarged body 4, insert steel pipe device 5,
Steel pipe 6, short muscle 7, injected hole 8, angle bar guard member 9, cuff 10, closed end 11, upper load body 12, steel pipe soil cement one
Force structure 13.
Embodiment 1: the present embodiment is specifically related to a kind of oblique steel pipe and combines the construction method of soil cement formation beaer, should
Construction method comprises the steps:
(1) as it is shown in figure 1, moved by rig 1 to position to be onstructed, rig 1 is a mixing pile rig, regulate on it drilling rod 2 with
Inclination angle between ground is to designing requirement；After angular adjustment to be done, start drilling rod 2 oblique drilling and forming hole in the soil body；
(2) as it is shown in figure 1, treat that the stirring-head 2 of drilling rod 2 leading section creeps into after projected depth, drilling rod 2 continue to creep into one section away from
From, simultaneously by the outside jet cement serosity of stirring-head 2, under the stirring of stirring-head 2, cement grout mixes composition tiltedly with mud
To uniform soil cement enlarged body 4, beaer bearing capacity is preferable；
(3), as shown in Fig. 1,3,4,5, after the construction of soil cement enlarged body 4 to be done, drilling rod 2 lift-off is holed；Choose an external diameter
Slightly larger than the steel pipe 6 of aforementioned boring internal diameter, both constitute interference fit, so that steel pipe 6 can be by frictional resistance in the soil body；Profit
With the slotting steel pipe device 5 on rig 1, steel pipe 6 is inserted in soil cement enlarged body 4 along aforementioned boring；
Wherein, on the tube wall of steel pipe 6 end, i.e. the contacting on tube wall face, if being intervally distributed with of steel pipe 6 and soil cement enlarged body 4
Dry short muscle 7 and injected hole 8, for increasing the swimming cloths power of steel pipe 6 on the oblique wall being welded in steel pipe 6 of short muscle 7；Respectively
The outside of injected hole 8 is disposed with the angle bar guard member 9 in reversed acanthoid, and this angle bar guard member 9 can prevent soil-cement body from blocking note
Slurry hole 8, can improve again the combination stability between steel pipe 6 and soil cement enlarged body 11；The end of this external steel pipe 6 is additionally provided with envelope
Closed end head 11, the cuff 10 that connects through between closed end 11 and steel pipe 6 realizes, and the setting of cuff 10 can be made realizing connecting
While with, raising steel pipe 6 is with the contact area between soil cement enlarged body 4, thus improves combination stability；Additionally, blind end
11 can be in arc-shaped as shown in Figure 4, it is also possible in cone tip shape as shown in Figure 5, offer equally on closed end 11
There are injected hole 8 and angle bar guard member 9；
(4) as seen in figures 3-6, after steel pipe 6 is inserted in soil cement enlarged body 4, by the external grouting equipment in steel pipe 6 upper end,
Backward steel pipe 6 in inject serosity and carry out supplementing slip casting, the serosity injected hole 8 through end outwards overflows, and fills steel pipe 6 and cement
Space between soil enlarged body 4, so that steel pipe 6 is preferably combined with soil cement enlarged body 4, constitutes steel pipe soil cement and is integrally subject to
Power structure 13, to provide bearing capacity to top charge carrier 12.
Embodiment 2: as in figure 2 it is shown, the present embodiment is specifically related to a kind of oblique steel pipe combines the construction of soil cement formation beaer
Method, this construction method is with the difference of embodiment 1: rig 1 is specially a rotary churning pile rig, in its drilling rod 2 end
Corresponding gunniting hole is distributed on drill bit, and after the projected depth that drilling rod 2 creeps into the soil body, drilling rod 2 end starts injection
Cement grout, i.e. high-pressure rotary-spray creep into, so that cement grout and mud are mixed into one, form one section of oblique uniform cement
Soil enlarged body 4, the diameter of soil cement enlarged body 4 is more than bore diameter.
In the present embodiment, the construction method of remaining step is same as described in embodiment 1, therefore repeats no more.
