Description
Technical field
The present invention relates to water treatment building field of sealing technology, specially one kind can be applied in municipal field Pipeline Crossing Program not
The sealing device and construction method of the double walls of uniform settlement.
Background technology
In water treatment building design, to save land used, often by water storage structures and other structures close to construction.
Due to both sides structures function difference, structure construction has differences, and subsiding crack is arranged at two kinds of structures close neighbours and forms double walls.
In most cases, since both sides structure sedimentation amount difference causes double walls to occur differential settlements, whens Pipeline Crossing Program double walls, will
Face the failure by shear risk that differential settlement is brought.Meanwhile if at the double walls of Pipeline Crossing Program under water level located underground, due to
The packing material of subsiding crack is unable to reach airtight waterproof between double walls, and underground water enters both sides structures possibly through gap.
To solve this problem, design mostly uses following technical measures greatly at present：In Pipeline Crossing Program water storage structures side
Wall on the pre-buried sealing casing to match with crossing pipeline diameter, it is poor further according to the both sides structure sedimentation amount estimated,
The pre-buried sealing casing being relatively large in diameter on the side wall of non-water storage structures.After both sides walls concrete pours, first will
Pipeline is tamped with sealing casing and pipeline enclosure gap on water storage structures wall with rigid seal material, then pipeline is passed through non-storage
Sealing casing on water structures wall, the gap between casing and pipeline use flexible material temporary sealing, on the one hand avoid two
Side structure sedimentation difference can also play the work for preventing underground water from entering structures by gap of stretching to the failure by shear of pipeline
With.
Both sides structures are basically completed the 80% of final settlement through ballast or full load one month or so time of sedimentation
Left and right, need during this period the temporary sealing material between pipeline and sealing casing carry out repairing at any time it is perfect.Subsequent one
In the time in or so year, it need to continue to observe and repair sealing material, adapt to the sedimentation subsequently constantly occurred, until both sides wall reaches
To final settlement.
The technical measures of the double walls of existing Pipeline Crossing Program differential settlement, in both sides structures reach final settlement it
Before, it needs repeatedly to repair the sealing material at pipeline through-wall, follow-up management operation is more complicated, and it is hidden to also increase engineering
Suffer from.
Invention content
In order to overcome the above technical defects and insufficient, the present invention provides a kind of the close of double walls of Pipeline Crossing Program differential settlement
