Description
Technical field
The present invention relates to the method that freezing pipe processes, be specifically related to freezing pipe processing method at a kind of chamber.
Background technology
Freezing shaft construction in the past does not the most use to be freezed entirely deeply, freezing pipe does not pass through the chamber relevant to pit shaft, therefore, in the past freezing pipe process general wait freeze to terminate after 3～in 5 months, carry out tube drawing and freezing pipe closure, closure typically uses injects the western dreg concrete of cement bonded sand pulp grinder in pipe on ground；As freezing pipe fails to extract, use carry out perforation slip casting closure in the face of freezing pipe.Along with the increasing of the shaft construction degree of depth, pit shaft discloses water-bearing layer to be increased, and the Northwest's Jurassic stratum is because containing pore water, grouting water blockoff difficulty, the most generally preferably freezing Jurassic stratum, therefore pit shaft deep freezeout entirely in the Northwest's is more.
Summary of the invention
The deficiency existed according to prior art, it is provided that one has saved the sinking shaft duration, reduces freezing pipe processing method at the chamber of security risk.
Technical solution of the present invention realizes by the following method:
Freezing pipe processing method at a kind of chamber, the method comprises the following steps:
A. after being drained by the water in freezing pipe, around the freezing pipe at 400mm～600mm at excavated section, brush off rock with pneumatic pick, then cut off freezing pipe in excavated section position, in freezing pipe, put into polyethylene tube.
B. the punching pipe of a band gingival cyst of mucous gland in the newborn is processed, by the punching pipe of band gingival cyst of mucous gland in the newborn and the following Plate Welding welding quick coupling I, and quick coupling I connection welded below with steel plate by the punching pipe of band gingival cyst of mucous gland in the newborn, welds a quick coupling II again in the side of freezing pipe.
C. the punching pipe of band gingival cyst of mucous gland in the newborn is connected with the polyethylene tube putting into freezing pipe, then by moving on steel plate, with freezing pipe welded closure.
D. weld a steel pipe on the steel plate outside freezing pipe, in mm～250mm of steel pipe top 150, make floral tube, below steel plate, then weld a quick coupling connected with steel pipe III, finally steel pipe is reached in the space of boring.
E. will be with joint, the mouth of pipe carries out after being connected with quick coupling equipped with the high-pressure hose of high-pressure ball valve pouring into a mould concrete.
F., after concrete cast, thaw from quick coupling I, quick coupling II below, by bleeding off with the water of pipe outer void in freezing pipe after defrosting, estimate grouting amount according to defrosting drillhole height, to Grouting Pipe and pipe outside borehole standoff slip casting reinforce.
A diameter of 75mm of described polyethylene tube, a length of 30mm.
The punching length of tube of described band gingival cyst of mucous gland in the newborn is 300mm.
Described steel plate thickness is 10mm.
Described quick coupling I is 3 cun of snap joints, and described quick coupling II is 3 cun of snap joints, and described quick coupling III is 2 cun of snap joints.
The a length of 200mm of described floral tube, wraps up filling with plastic bag under floral tube, prevents from being blocked by floral tube during cast.
The invention has the beneficial effects as follows:
By using this kind of construction method, successfully implement Chamber Construction during freezing and pass through freezing pipe, use down-hole treatment freezing pipe technology, saved the sinking shaft duration, reduced security risk.
Accompanying drawing explanation
Fig. 1 is skip bucket chamber freezing pipe distribution plane figure；
Fig. 2 is that freezing pipe processes schematic diagram；
1 skip loading pocket, 2 freezing pipes, 3 borings, 4 polyethylene tubes, the punching pipe of 5 band gingivals cyst of mucous gland in the newborn, 6 quick couplings II, 7 quick couplings I, 8 quick couplings III, 9 steel plates, 10 steel pipes, 11 floral tubes, 12 excavated sections.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, technical solution of the present invention is described further.
As shown in Figure 1 and Figure 2, when using sequence construction method, i.e. shaft construction to chamber opening part when this pit shaft freezing degree of depth exceedes during skip loading pocket 1, shaft construction, proceed to Chamber Construction, after Chamber Construction, proceed to shaft construction again.Owing to lower wellbore freezes not yet to terminate during construction skip loading pocket 1, therefore tube drawing filling sealing of hole cannot be carried out as conventional after freezing to terminate.The arrangement and method for construction used is: the freezing pipe 2 in the range of Chamber Construction closes the brine recycling freezed, and after down-hole Chamber Construction exposure freezing pipe, the saline in blow-down pipe, cuts off freezing pipe, block freezing pipe 2 in down-hole.
Specifically comprise the following steps that
A. after being drained by the water in freezing pipe 2, around the freezing pipe 2 at the 500mm away from excavated section 12, brush off rock with pneumatic pick, then cut off freezing pipe 2 in excavated section 12 position, in freezing pipe 2, put into the polyethylene tube 4 of a diameter of 75mm, a length of 30mm.
B. the punching pipe 5 of the band gingival cyst of mucous gland in the newborn of one a length of 300mm of processing, the punching pipe 5 of band gingival cyst of mucous gland in the newborn is welded 3 cun of quick couplings I 7 with following, thickness is that the steel plate 9 of 10mm welds, and 3 cun of quick coupling I 7 connections welded below with steel plate 9 by the punching pipe 5 of band gingival cyst of mucous gland in the newborn, weld 3 cun of quick couplings II 6 again in the side of freezing pipe 2.
C. the punching pipe 5 of band gingival cyst of mucous gland in the newborn is connected with the polyethylene tube 4 putting into freezing pipe 2, then by moving on steel plate 9, with freezing pipe 2 welded closure.
D. weld a steel pipe 10 on the steel plate 9 outside freezing pipe 2, by making the floral tube 11 of a length of 200mm in steel pipe 10 top 200mm, under floral tube, wrap up filling with plastic bag, prevent from being blocked by floral tube during cast,
Then below steel plate 9, weld the 2 cun of snap joints III 8 connected with steel pipe 10, finally steel pipe 10 is reached in the space of boring 3.
E. will be with joint, the mouth of pipe carries out after being connected with quick coupling equipped with the high-pressure hose of high-pressure ball valve pouring into a mould concrete.
F. after concrete cast, thaw below I 7,3 cun of quick couplings II 6 of 3 cun of quick couplings, to bleed off with the water of pipe outer void in freezing pipe after defrosting, according to thawing, grouting amount is highly estimated in boring 3, to Grouting Pipe and pipe outside boring 3 gap slip casting reinforce.
By using this kind of construction method, successfully implement Chamber Construction during freezing and pass through freezing pipe, use down-hole treatment freezing pipe technology, saved the sinking shaft duration, reduced security risk.
