Detailed description of the invention
In order to enable clearly to illustrate the technical characterstic of this device, below by detailed description of the invention, and combine its accompanying drawing, to this
Invention is described in detail.
The present invention provides a kind of pipe gallery internal pipeline adjusting means, and as depicted in figs. 1 and 2, this adjusting means is by managing
Road bearing 4, upper screw 5, bottom screw rod 8, nut 6, base 9 and guide rod 11 form, and upper screw 5 and bottom screw rod 8 use
The screw thread in different precession directions so that when nut 6 rotates, upper screw 5 and bottom screw rod 8 or screw out simultaneously or revolve simultaneously
Entering, upper screw 5 is fixing with pipe support 4 to be connected, and pipeline 2 uses clip 1 and fastening screw 3 to be fixed on pipe support 4, under
Portion's screw rod 8 is fixing with base 9 to be connected, and upper screw 5 is connected by nut 6 with bottom screw rod 8, and nut 8 both sides arrange hole, its
Diameter is more than guide rod 11 diameter, can pass through guide rod 11 rotating nut 8, it is achieved the raising and lowering of pipe support 4.
Embodiment 1
After plain concrete cushion layer has been constructed, from down to successively bottom pipe gallery and between C15 plain concrete cushion layer
Construction 1.5mm thickness PVC waterproof roll (internal reinforcing type), sealing coat (polyethylene film) and 50mm thickness C20 pea gravel concreten
Protective layer.
For cast-in-place pipe gallery, armored concrete pours and pours at twice, and the first stage pours piping lane 10 the latter half,
Base 9 can use xoncrete structure (or use be capable of with piping lane 10 and bottom screw 8 binding purpose other materials knot
Structure), and with piping lane 10 the latter half one-piece casting, base 9 absolute altitude uses design load, and bottom screw rod 8 is embedded into base 9
In, second stage pours piping lane 10 top half, first stage and second stage and uses steel plate water stopper to connect.Combine for prefabricated
Closing piping lane, piping lane 10 and base 9 primary concreting, remaining is identical with cast-in-place pipe gallery.
Pipe gallery answers lateral symmetry to backfill when backfill, and its absolute altitude should of substantially equal and same be on a horizontal plane,
Backfill order should be layered from high to low by base course drainage direction and carry out, and backfilling material layering paves, and after often lamination is real, thickness does not surpasses
Cross 200mm.
Before laying the internal pipeline 2 of pipe gallery 10, being first screwed on bottom screw rod 8 by nut 6, upper screw 5 can
It is welded as entirety with pipe support 4, then screws upper screw 5 to nut 6, and the termination of retaining nut 6 as far as possible exists respectively
Upper screw 5 and the centre of bottom screw rod 8, to facilitate the adjustment of later stage height, confirm that pipe support 4 reaches designed elevation,
After pipeline 2 uses clip 1 and fastening screw 3 are fixed on pipe support 4.
In the event of descending water level decreasing partly or closing on construction infection and cause foundation soil to produce in running
Differential settlement, there is faulting of slab ends phenomenon in piping lane deformation joint, and pipeline is it is possible to there is functional disorder, and serious meeting causes city
The comprehensive function of system is paralysed.If settling excessive, exceed the adjustable-height of adjusting means, then must use foundation stabilization, but
The method cost is high, of long duration；If sedimentation is not very big, but have impact on the normal use of pipeline 2, now can be by through suspension ring
Two guide rod 11 rotating nuts 8 of 7, it is achieved the lifting of pipe support 4, realize the raising and lowering of pipeline 2 further, can be quick
, economical, effective recover pipeline 2 normal usage function.
Embodiment 2
Base 9 uses steel construction, and is fixed with piping lane 10 by prefabricated embedded part, arranges corresponding with bottom screw rod 8 in base 9
Female thread, bottom screw rod 8 can be connected with base 9 by screwing.Correspondingly, upper screw 5 can also be passed through with pipe support 4
Similar approach connects.
It is same as in Example 1 that remaining does not describes part in detail.
Embodiment 3
For realizing the rotation of nut 8, it is possible to arrange through hole in the middle of nut 8, guide rod 11 can be passed during use
Hole.
After piping lane agent structure and pipe laying, if uneven sedimentation occurs in running, by wearing
Cross guide rod 11 rotating nut 8 of hole, it is achieved the lifting of pipe support 4, realize the raising and lowering of pipeline 2 further.
It is same as in Example 1 that remaining does not describes part in detail.
Further improving as above-described embodiment, as shown in Figures 3 to 5, above-mentioned piping lane is by multiple prefabricated tube couplings
Assembled, one end of each prefabricated tube coupling arranges tenon 24, and the other end arranges mortise 25, in the two ends of each prefabricated tube coupling
Sidewall circumference is provided with flange, presets axial stretch-draw hole 23 on described flange；As it can be seen, the prefabricated tube coupling in top 21
The mortise 25 of tenon 24 tube coupling prefabricated with bottom 28 assembled, twice waterproof sealing gasket is set between tenon 24 and mortise 25
Sheet 27, tenon 24 and mortise 25 internal reservation stretch-draw hole 23, stretch-draw hole 23 is internal is provided with steel strand wires 29, is drawn by fastening screw 22
Tight steel strand wires 29 will couple together, outside tenon 24 and mortise 25 by the prefabricated tube coupling in top 21 tube coupling prefabricated with bottom 28 closely
Side can be wrapped up with waterproof roll 26.
The pipeline axis of planning is excavated ground and to projected depth and designs width, for not meeting the ground that design requires
Base is processed by design requirement, is reaching the concrete cushion of cast-in-place 15cm on the ground that design requires, is treating concrete final set
After, bed course is laid 10mm thickness yellow ground, and minimizing friction levelling for bed course.
The prefabricated tube coupling in flat car transport top 21 and the prefabricated tube coupling in bottom 28 are marched into the arena, and crane hangs prefabricated tube coupling and enters groove,
Between the mortise 25 of the prefabricated tube coupling of tenon 24 and bottom 28 of the prefabricated tube coupling in top 21, twice waterproof sealing pad 27 is set, can borrow
Help bottle gouard moved by hands that the axial location of prefabricated tube coupling is adjusted so that the prefabricated tube coupling in top 21 and bottom prefabricated tube coupling 28 are abundant
Contact.
After prefabricated tube coupling assembly, check axis absolute altitude and the uniformity of piece distance.Meet after requiring, organizing construction personnel
Tube coupling 21 prefabricated to top and the prefabricated tube coupling in bottom 28 are connected by steel strand wires 29, and fastening bolt 22 is passed through in one end of steel strand wires 29
Being fixed on the prefabricated tube coupling in top 21, the other end is fixed on the prefabricated tube coupling in bottom 28 by fastening bolt 2, and fastening bolt 22 is adopted
With high-strength bolt, simultaneously must be qualified through shear test, during connection, elder generation's diagonal connects, and connects, each fastening the most comprehensively
Bolt 22 can not disposably be screwed to the end, first should just be screwed into place, then move back stubborn several, then screw up with a wrench.
Fastening bolt 22 to check after tightening comprehensively, and Tightening moment is not less than 0.9kN m, then tenon 24 He
Laying water-proof coiled material 26 outside mortise 25, seals structure with protection, when paving it should be noted that get rid of air with water extruding, in order to avoid producing
Raw bulge phenomenon.
The most assembled all of prefabricated tube coupling, until engineering terminates.
Above-mentioned detailed description of the invention cannot function as limiting the scope of the invention, for the technology people of the art
For, any alternate modification being made embodiment of the present invention or conversion all fall within protection scope of the present invention.
The present invention does not describes part in detail, is the known technology of those skilled in the art of the present technique.
