Abstract
The utility model discloses a kind of X-type freezing pipe, body section is X-type, is inserted with feed pipe in body, and the top of feed pipe is provided with liquid back pipe.Freezing pipe is low-carbon (LC) seamless steel pipe or pvc pipe or PPR pipe or ABS pipe or PE pipe.The beneficial effects of the utility model: compared with the circular freezing pipe technology of tradition, X-shaped freezing pipe 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.
Description
Technical field
The utility model relates to a kind of freezing pipe, particularly a kind of X-type 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.Artificial Soil freezing process, owing to not substantially being subject to the restriction of supporting scope and the supporting degree of depth, effectively can preventing the distortion of adjacent upper body during water burst and city are excavated, Drilling is constructed and be subject to increasing attention, one of technical way becoming underground construction.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 indifferent in order to solve existing freezing pipe single valve freezing, causes the problem substantially increasing circulating refrigerant medium consumption and construction machinery energy consumption and a kind of X-type freezing pipe provided.
The body section of the X-type freezing pipe that the utility model provides is X-type, is inserted with feed pipe in body, and the top of feed pipe is provided with liquid back pipe.
Freezing pipe is low-carbon (LC) seamless steel pipe or pvc pipe or PPR pipe or ABS pipe or PE pipe.
Construction method is as described below:
One, preparation of construction
(1) require to supply water in advance, supply power near construction plant, and clear up tunnel and construction plant, ensure that construction is current smooth and easy.
(2) " freezing hole construction scaffold built by steel pipe, installs boring construction lifting platform to creep into requirement by the freezing hole of diverse location, with 1.5.
(3) construction equipment is marched into the arena.Because scene is large to construction infection, reasonable arrangement construction equipment is answered to transport the time sequencing of infield to.
Two, freezing borehole construction
(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.
The beneficial effects of the utility model:
Freezing pipe outer wall forms X-shaped cavity in the earth formation, and feed pipe is put at heart position wherein, and arrange liquid back pipe at freezing pipe head, coolant media flows into from feed pipe simultaneously, flows out through liquid back pipe, and so circulation forms X-shaped Frozen Soil Cylinder in the earth formation.Compared with the circular freezing pipe technology of tradition, X-shaped freezing pipe 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.

Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2:
Body 1 section of the X-type freezing pipe that the utility model provides is X-type, is inserted with feed pipe 2 in body 1, and the top of feed pipe 2 is provided with liquid back pipe 3.
The body 1 of freezing pipe is low-carbon (LC) seamless steel pipe or pvc pipe or PPR pipe or ABS pipe or PE pipe.
Construction method is as described below:
One, preparation of construction
(1) require to supply water in advance, supply power near construction plant, and clear up tunnel and construction plant, ensure that construction is current smooth and easy.
(2) " freezing hole construction scaffold built by steel pipe, installs boring construction lifting platform to creep into requirement by the freezing hole of diverse location, with 1.5.
