Description
Technical field
The present invention relates to hydro project technical field, especially relate to a kind of aqueduct adjacent across the water sealing structure at seam place.
Background technology
Aqueduct adjacent across between seam place need to establish water sealing structure, usually adopt and waterstop embedded or is overlapped in adjacent two on aqueduct, stop trough inner water outwards to flow out. Above-mentioned waterstop is generally rubber fastening band or Copper water stop band. Adopting the aqueduct of full hall frame cast-in-place construction, waterstop material can select rubber or copper sheet, is directly built by waterstop in groove body when groove body is built. Adopt the aqueduct of prefabrication and lifting construction, fill mode after general employing and rubber fastening band is installed: be reserved with water stopping trough at aqueduct two ends, after groove body hoisted in position, in water stopping trough, rubber fastening band bolt, colloid etc. are fixed on water stopping trough bottom surface, in later stage groove, adopt material envelope to fill out. Adopting Channel Maker construction and reserve the aqueduct of post-cast strip, its sealing construction mode is identical with full hall frame, is directly built by waterstop in concrete when building second phase post-cast strip; Adopting the aqueduct of the not reserved post-cast strip of Channel Maker construction, its sealing construction mode and prefabricated construction aqueduct are similar. Full hall frame cast-in-place construction or Channel Maker are constructed and are reserved the aqueduct of post-cast strip, and waterstop directly pours into concrete, and weather resistance is better, and construction is relatively convenient. And the aqueduct of prefabrication and lifting construction or the reserved post-cast strip of Channel Maker construction, rear-loading type waterstop generally adopts elastomeric material, though later stage water stopping trough have material envelope fill out weather resistance not as copper sheet; Need to shifting to an earlier date pre-embedded bolt or later stage implantation bolt during construction, above-mentioned bolt also needs location on one wire, and operation is more; Although the rear-loading type waterstop later stage is replaceable, but need to cut envelope underfill material, twisting off nut, remove waterstop, install new waterstop, again bolt on, fill envelope underfill material etc., operation is many, constructs more complicated.
Summary of the invention
The present invention provide a kind of aqueduct adjacent across the water sealing structure at seam place, object is that the waterstop solving the aqueduct adjacent cross-over connection seam place installation of prefabrication and lifting construction or the reserved post-cast strip of Channel Maker construction easily damages, and installs, changes the problem of complex procedures.
For achieving the above object, the present invention can take following technical proposals:
Aqueduct of the present invention adjacent across the water sealing structure at seam place, the waterstop comprising adjacent left side aqueduct body, right side aqueduct body and be attached thereto, described right side aqueduct body offers the water stopping trough that section form is " L " shape structure, described section form be " L " shape structure water stopping trough in be filled with pea gravel concreten, section form is be provided with built-in fitting bottom the water stopping trough of " L " shape structure;Described waterstop by left wing plate, right wing plate and be positioned at middle part U-bend form; Left wing plate is embedded in the aqueduct body of described left side; Right wing plate is bonded in described built-in fitting upper surface, and soldered with built-in fitting right part together with; Described U-bend is positioned at the seam place of left and right aqueduct body, is filled with water-proof material in U-bend, is all filled with cystose in U-bend top and lower space, and the described cystose surface of upper space is provided with sealant layer.
Described left wing plate is provided with bending section upwards.
Aqueduct provided by the invention adjacent across the water sealing structure at seam place, structure is simple, and easy construction is durable in use, and sealing is reliable, and with low cost, its concrete advantage is as follows:
1, waterstop of the present invention adopts Copper water stop band, and the rubber fastening band weather resistance that more current prefabricated construction or Channel Maker construction do not establish the aqueduct of post-cast strip to use is better;
2, when aqueduct is prefabricated, Copper water stop band left wing plate is directly embedded in the concrete of left side aqueduct body, not only ensures the quality of waterstop, and has been located by waterstop, is convenient to the installation of waterstop right wing plate;
3, Copper water stop band right wing plate with right side aqueduct body section form be the water stopping trough bottom surface of " L " shape structure to bury copper coin in advance bonding, end is welded with prefabricated component, and the penetrating passage of shutoff between waterstop and copper coin, ensure that stagnant water effect;
4, the installation process of this water sealing structure is few, easier for installation compared with the rear-loading type rubber fastening band working procedure that current prefabricated construction or Channel Maker construction do not establish the aqueduct of post-cast strip to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in Figure 1, aqueduct of the present invention adjacent across the water sealing structure at seam place, the Copper water stop band comprising adjacent left side aqueduct body 1, right side aqueduct body 2 and be attached thereto, right side aqueduct body 2 offers the water stopping trough 4 that the section form that section is L-shaped is " L " shape structure, being filled with pea gravel concreten 5 in the water stopping trough 4 that section form is " L " shape structure, bottom it, built-in fitting 6 is for being not less than the thick copper coin of 3mm; Described Copper water stop band by left wing plate 3.1, right wing plate 3.2 and be positioned at middle part U-bend 3.3 form; Copper water stop band left wing plate 3.1 is embedded in the aqueduct body 1 of left side; Copper water stop band right wing plate 3.2 is bonded in the upper surface of built-in fitting 6, and soldered with built-in fitting 6 right part together with; U-bend 3.3 is positioned at the seam place of left and right aqueduct body 1,2, is filled with the water-proof material 7 of Bituminous hemp fiber in U-bend 3.3, is all filled with cystose 8 in U-bend 3.3 top and lower space, and cystose 8 surface of upper space is provided with sealant layer 9.
