Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, to specific embodiment, structure, feature and its effect is proposed according to the present invention, detailed description is as follows.
Refer to Fig. 2, the brick projecting construction of working shaft method of one kind of first embodiment of the invention, comprising:
A, underground utilities position is verified；
Fig. 3 is referred to, b, symmetrically cutting the earth along 1 marginal position of active well builds active well 1, when the work of a section digging depth
After well 1 puzzles, the earthwork in middle position being excavated, then excavating next 1 marginal position of section active well, 1 intensity of active well reaches
Lower section excavation, each excavation width≤1200mm, depth≤1000mm, until in planned well below the absolute altitude of bottom are carried out after 70% again
Until 300mm.
C, when driving arrives underground utilities position, whole pipelines is dug out, whole pipelines is banded together, pipeline passes through
Band is tied up.
Fig. 4, Fig. 5 are referred to, d, is arranged sheath 2 outside the pipeline banded together, the sheath 2 includes that section is semicircle
The the first pipe valve 21 and the second pipe valve 22 of shape, the first pipe valve 21 and the second pipe valve 22, which have, is used for bolted spiral shell
Hole 23.Sheath 2 further includes the fixed link 24 being fixedly connected with 1 borehole wall of active well, and fixed link 24 is for fixing the sheath 2.
E, sheath 2 is connected and fixed with the active well 1 puzzled；
Fig. 6 is referred to, f, continuing symmetrically to cut the earth along 1 marginal position of active well builds active well 1, when a section digging depth
After active well 1 puzzles, the earthwork in middle position is excavated, then excavate next 1 marginal position of section active well, until completing whole works
Make well 1.4 thickness of bottom plate is 200mm, concrete C25, and after active well 1 to set absolute altitude, concrete is arranged further according to pipeline rout
Under the premise of meeting the push pipe working space brick film 11 is arranged in position of back size as needed, in stock mould in rear backrest
C25 concrete is poured between 11 and well bore, as push pipe backrest.
Sheath 2 is made of multiple sheath tube coupling 2a, and sheath tube coupling 2a is connect with another sheath tube coupling 2a by flange 25 solid
It is fixed.The sheath 2 is made of metal.
The step b further includes masonry, and 1 marginal position of active well is built by masonry.The masonry is 370 bricks
Wall.
When constructing to active well 1, being exposed to outer pipeline, there are security risks, and weight falls meeting to pipeline
It damages, therefore the sheath 2 being sheathed on outside pipeline ensure that construction safety.It, can be to pipeline when being backfilled to active well 1
Inward pressure is generated, if backfill unevenly can also be such that pipeline deforms, therefore the sheath 2 being sheathed on outside pipeline avoids pipeline
Using safe.
Refer to Fig. 7, in the second embodiment of brick projecting construction of working shaft method of the invention, according to soil property situation and
Cutting depth, 2 meters to divide into reinforced concrete circle beam 3 one, collar tie beam 3 using 400mm X400mm reinforced concrete structure,
