Description
Technical field
The utility model belongs to construction of diaphragm wall field in underground engineering, is specially a kind of diaphram wall lap guard
Stream, water-impervious I-shaped steel joint structure.
Background technology
Diaphram wall has earth-retaining, antiseepage effect concurrently, while because its overall stiffness is big, Construction Vibration is small, ground adaptability
The advantages that strong, be widely used in deep-foundation pit engineering.Diaphram wall by unit groove section one by one by connector be connected with each other and
Into the quality of connector is directly related to the globality of wall body structure and the reliability of antiseepage, is more related to the peace of whole engineering
Quan Xing.
I-shaped steel joint is widely used in ground at present because of the advantages that its overall stiffness is high, installation is simple, seepage flow route is long
In the connector construction of lower diaphragm wall.But because the reason for grooving error of perpendicularity and cover to reinforcement, make it that common I-shaped steel joint is easy
Concrete is produced around flow phenomenon, while again because using mud off during grooving, connector cleaning is not thorough in the presence of folder mud phenomenon
So that the easy percolating water of diaphram wall seam crossing.
Therefore, it is necessary to study a kind of diaphram wall prevent streaming, water-impervious I-shaped steel joint structure, it is ensured that seam crossing is applied
Working medium amount.
The content of the invention
The utility model aim be propose a kind of diaphram wall simple in structure, safe and reliable prevent streaming, antiseepage water conservancy project
Word steel joint design, solves the problem of underground continuous wall connector infiltration.
The utility model adopts the following technical scheme that realization：
A kind of diaphram wall is prevented streaming, water-impervious I-shaped steel joint structure, including by two pieces of wing plate shaped steel and one piece of abdomen
The I-steel that template steel is welded.
Horizontal distribution muscle on the inside of the wing plate shaped steel of the I-steel side with groove section steel reinforcement cage in advance welds to form entirety,
It is respectively welded on the outside of the wing plate shaped steel of the I-steel side and only starches iron sheet, the only slurry iron sheet is bonded with groove section side wall.
Rubber fastening band is symmetrically arranged with the inside of the wing plate shaped steel of the I-steel opposite side, the wing of the I-steel opposite side
It is placed with follow-up groove section steel reinforcement cage on the inside of template steel, the connection of horizontal distribution muscle and termination reinforcing bar in the follow-up groove section steel reinforcement cage
Place is connected by sealing vertical bars, and the follow-up groove section steel reinforcement cage is by sealing vertical bars and the wing plate shaped steel inner side of I-steel opposite side
Rubber fastening band be in close contact.
Preferably, rubber fastening band is in ripple as preferred rubber waterstop using binding agent and wing plate shaped steel inner adhesion
Shape wave, end head to afterbody progressive additive, decentralization and sealing vertical bars beneficial to follow-up groove section steel reinforcement cage connect with rubber fastening band
Touch even closer, percolation-proof effect enhancing；Follow-up groove section steel reinforcement cage horizontal distribution muscle termination corner welded seal vertical bars, with rubber
Glue waterstop is close（Sealing）Contact；The hot rolling plain bar that vertical bars select diameter phi 20mm is sealed, ensures the intensity of steel reinforcement cage
And the compactness with rubber fastening band；I-shaped steel joint bottom cutting shoe length is not less than 1m.
Compared with prior art, the beneficial effects of the utility model are：
1st, iron sheet is only starched in welding on the outside of groove section I-shaped steel joint wing plate in advance, due to concrete pressure iron sheet fitting groove section side
Wall, makes the enclosure space of groove section side formation in advance, prevents concrete from forming residue around follow-up groove section is flowed to.
2nd, I-shaped steel joint bottom cutting shoe in echelon be easier insertion groove section bottom solum in, prevent slot bottom concrete around
Stream.
3rd, in follow-up groove section steel reinforcement cage insertion I-shaped steel joint, the sealing vertical bars and I-steel of follow-up groove section termination corner are made
Wing plate inner rubber waterstop fits closely, and is conducive to prevent because connector cleaning is not thorough the folder mud phenomenon of generation, so as to avoid
Wall interior solid weakens so that diaphram wall percolating water, water burst gush the generation of husky harm.
