Abstract
The utility model provides a pipe is freezed to abnormal shape, characterized by includes feed pipe (1), freeze tub (2), slip casting filler (3) and go back to liquid pipe (4), feed pipe (1) is located and freezes tub (2) central authorities, freezes tub cross sectional shape of (2) for square, I shape, triumph, X type, T type or Y type, freezes tub (2) surface for slip casting filler (3), goes back to liquid pipe (4) and feed pipe (1) and stretches out and freeze tub part of (2) and be linked together. Compare with the circular tub technique of freezing of tradition, the utility model discloses a dysmorphism freezes the pipe and has a great unit volume material specific surface, therefore can improve the single tube greatly under the prerequisite of the volume of increasing the engineering not and freeze the ability to improve the price / performance ratio. Its periphery is grown up, circulation refrigerant medium quantity is few, and this technique has outstanding advantages such as the construction practicality is strong, control of construction quality convenient, the effectual and economic nature superiority of reinforcement, has great popularization and application and is worth.
Description
Technical field
The utility model relates to cyopedology technical field, especially a kind of special-shaped freezing pipe.
Background technology
Artificial stratum freezing process utilizes artificial cooling technology; make the water freezing in stratum; natural ground is become frozen soil; increase its strength and stability; contacting of isolated underground water and underground construction; to carry out the special constructional technique of underground engineering construction under the protection of frost wall, its essence is and utilize artificial cooling Iterim Change rock and soil properties with strengthening stratum.Engineering with artificial freezing method due to substantially not by the restriction of supporting scope and the supporting degree of depth, effectively can prevent that water burst and city from excavating, in Drilling construction the adjacent soil body distortion and be subject to increasing attention, become underground construction technical way it.
Traditional freezing pipe is the single round tube of shape, causes single valve freezing indifferent, substantially increases circulating refrigerant medium consumption and construction machinery energy consumption.
Summary of the invention
The purpose of this utility model is to provide a kind of special-shaped freezing pipe.Solve the indifferent problem causing increase circulating refrigerant medium consumption and construction machinery energy consumption of existing freezing pipe single valve freezing, traditional round tee section is designed to odd-shaped cross section.
The technical solution of the utility model is:
A kind of special-shaped freezing pipe, comprise feed pipe 1, freezing pipe 2, slip casting filler 3 and liquid back pipe 4, described feed pipe 1 is positioned at freezing pipe 2 central authorities, the cross sectional shape of freezing pipe 2 is square, I shape, triangular form, X-type, T-shaped or Y type, freezing pipe 2 external surface is slip casting filler 3, and the part that liquid back pipe 4 stretches out freezing pipe 2 with feed pipe 1 is connected.
The material of described freezing pipe 2 is seamless low carbon steel pipe.
The material of described freezing pipe 2 is PVC plastic, PPR plastics, ABS plastic or PE plastics.
It is peripheral that frozen soil 5 and non-frozen soil 6 are enclosed in slip casting filler 3 with this.
The beneficial effects of the utility model are:
Compared with the circular freezing pipe technology of tradition, special-shaped freezing pipe of the present utility model has larger unit volume material specific surface area, thus can greatly improve single valve freezing ability under the prerequisite not increasing engineering quantity, thus improves cost performance.Grow up in its periphery, circulating refrigerant medium consumption is few, and this technology has that practical, the quality control on construction of construction is convenient, consolidation effect is good and the outstanding advantages such as economy is superior, has larger application value.
Accompanying drawing explanation

Fig. 2 is vertical section structure schematic diagram of the present utility model.
Fig. 3 is construction flow chart of the present utility model.
In figure: 1, feed pipe; 2, freezing pipe; 3, slip casting filler; 4, liquid back pipe; 5, frozen soil; 6, non-frozen soil.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As Fig. 1 to 3, a kind of special-shaped freezing pipe, comprise feed pipe 1, freezing pipe 2, slip casting filler 3 and liquid back pipe 4, described feed pipe 1 is positioned at freezing pipe 2 central authorities, the cross sectional shape of freezing pipe 2 is square, I shape, triangular form, X-type, T-shaped or Y type, freezing pipe 2 external surface is slip casting filler 3, and the part that liquid back pipe 4 stretches out freezing pipe 2 with feed pipe 1 is connected.
The material of described freezing pipe 2 is seamless low carbon steel pipe.
The material of described freezing pipe 2 is PVC plastic, PPR plastics, ABS plastic or PE plastics.
It is peripheral that frozen soil 5 and non-frozen soil 6 are enclosed in slip casting filler 3 with this.
Star-like freezing pipe utilizes the freezing pipe of a kind of cross section as star-like to replace traditional circular outer wall, freezing pipe forms star-like cavity in the earth formation, feed pipe is put at heart position wherein, liquid back pipe is set at freezing pipe head simultaneously, coolant media flows into from feed pipe, flow out through liquid back pipe, circulation like this forms star-like Frozen Soil Cylinder in the earth formation.
Freezing borehole is constructed
(1) according to construction reference point, freezing hole is arranged by freezing hole construction figure.The biased difference in hole should not be greater than 100mm.
(2) horizontal drilling uses MD-60A type rig, and vertical drilling selects GXY-1 type rig to creep into.Before horizontal drilling, orifice tube and port seal to be installed.After first hole is opened, do not have Sand can continue to creep into, but boring later still to fill opening arrangement, occur in case broke-out diseases gushes sand phenomenon; If Sand is more severe, also answer cement injection (or dual slurry) sealing.
(3) in order to ensure Drilling Precision, perforate section is crucial.When creeping into front 5m, to repeatedly check drilling rod verticality, adjustment rig position, and adopt decompression to creep into, can continue to creep into after detecting deflection no problem.
(4) under freezing pipe in hand-hole before want first pipe arrangement, ensure freezing pipe concentricity.During welding, weld seam is full, ensures that freezing pipe has sufficient intensity, in order to avoid fracture of freezing pipe during tube drawing.After lower good freezing pipe, adopt transit Inclination Measurement by Light method to detect, the then repetition measurement freezing hole degree of depth, and carry out suppressing leak test.
(5) the underproof freezing pipe of pressure testing must carry out can using after process reaches seal request.Can propose to manage in hole by root, and with slush pump, weld seam one by one be suppressed, find out and leak weld seam and reason, process in time, and perform record, still must self-inspection after entering under secondary.
(6) feed pipe is entered under in freezing pipe.Feed pipe bottom connects the long support of 150mm, Ф 12 reinforcement welding.Then install go, loop goat's horn and freezing pipe end cap.
(7) after freezing pipe installs, the mouth of pipe is blocked with stopper etc., in order to avoid foreign matter falls into freezing pipe.
(8) thermometer hole construction method is identical with freezing pipe.
Embodiment recited above is only be described preferred embodiment of the present utility model; not design of the present utility model and scope are limited; do not departing under the utility model design concept prerequisite; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement; all should fall into protection domain of the present utility model, the technology contents of the utility model request protection is all recorded in detail in the claims.
