Description
Technical field
The utility model relates to underground continuous wall construction techniques, the in particular to steel reinforcement cage of diaphram wall.
Background technique
Diaphram wall is foundation engineering.When construction, a kind of trench machine is used on the ground, along deep excavation project
Periphery axis (guiding wall), under the conditions of mud off, excavates out a long and narrow deep trouth.After clear slot, reinforcing bar is hung in slot
Then cage builds up a unit groove section with tremie method concreting.It is so spaced (1-3-5-2-4-6) paragraph by paragraph
Construction builds up continuous armored concrete wall together in underground, as intercept water, antiseepage, load-bearing, water-retaining structure.
Diaphram wall is due to setting and below ground, and depth is up to tens meters, and even more than 100 meters, subterranean wall is deeper,
More influenced by underground water leakage.Since diaphram wall is to construct paragraph by paragraph, adjacent two section concrete junction easily forms seam, leads
Cause leak.Seepy question is solved, one such method is the connector using special construction, such as uses more I-steel at present
Connector.
Diaphram wall generallys use stage construction method, and first interval construction one phase (1-3-5) wall section first excavates a phase
Slot section simultaneously places steel reinforcement cage and concreting, and the steel reinforcement cage of phase wall section construction has I-shaped steel joint, to a phase wall section
The second stage of (2-4-6) slot section is excavated after concrete scleroma again and places steel reinforcement cage and concreting, the steel of the second stage of wall section construction
Muscle cage does not have I-shaped steel joint.
In most of occasion, even if joint structure is good again, seepy question still can not be thoroughly solved.To find out its cause, constructing
When one phase wall section, for convenience of connector is transferred, there are certain gaps between connector and cell wall, in decentralization steel reinforcement cage after-pouring coagulation
When native, the concrete of fluid form can flow to the other side (the second stage of slot section) of I-shaped steel joint around connector.It is another around connector is flowed through
Side and the concrete to harden directly affect the construction of the second stage of wall section, can not be firmly combined with the second stage of wall section concrete.
Therefore, it is necessary to solve the problems, such as that concrete is around flowing through I-shaped steel joint when phase wall section construction.
Utility model content
The purpose of this utility model is to propose a kind of anti-by-pass means of underground continuous wall connector, can ensure that a phase wall section is applied
Working hour concrete achievees the purpose that improve the second stage of wall section construction quality not around I-shaped steel joint is flowed through.
The purpose of this utility model can be realized by following technical solution.
The anti-by-pass means of underground continuous wall connector, include steel reinforcement cage and I-shaped steel joint, and the steel reinforcement cage includes phase
The longitudinal reinforcement and transverse steel to connect, the both ends of steel reinforcement cage and I-shaped steel joint are welded to connect, and further include having galvanized steel plain sheet,
The galvanized steel edges of boards are welded in the wing plate end of I-shaped steel joint, and galvanized steel plain sheet becomes the additional wing plate of I-shaped steel joint, is located at
The nearly outside of steel reinforcement cage, the width of galvanized steel plain sheet is 600~800mm, length is equal with I-shaped steel joint.
Prioritization scheme: further including having junction block and sand packet section, and the length of junction block is 10~20m, sectional dimension is slightly less than
The slot inside dimension of I-shaped steel joint, the sand packet section are piled by multiple sand packets, and sand packet section and connector pipe end are butted into temporarily to block up
Column is placed in the outer groove of I-shaped steel joint, and the height of interim stifled column is equal with I-shaped steel joint.
When carrying out construction of diaphragm wall using the utility model, the utility model is put into the phase slot section excavated
Interior, the then concreting in a phase slot section is during which, soft due to galvanized steel plain sheet, concrete by galvanized steel plain sheet edge to
Outer extruding stops concrete to stream to (the second stage of slot section) on the outside of I-shaped steel joint to patch cell wall, galvanized steel plain sheet is supported.
In addition on a small quantity around the concrete for flowing through I-shaped steel joint, the interim stifled column being made of junction block and sand packet section will be located at
The I-shaped steel joint slot of the second stage of slot section is crammed, and is greatly reduced around the concrete for flowing through the second stage of slot section.
When the second stage of continuous wall groove segment is constructed, first junction block is taken out, then excavate the second stage of slot section, sand packet section is opened with the second stage of slot section
It digs while removing.
It compares with the prior art, the utility model has the following beneficial effects:
The utility model can effectively solve the problems, such as that concrete is around I-shaped steel joint is flowed through when phase slot section construction, to subtract
The difficulty that concrete is charged and attacked when few second phase slot section connector construction, improves construction efficiency and quality, and be simple and convenient to operate with structure
Practical feature.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is structure (part) schematic diagram of the utility model.
Specific embodiment
With specific embodiment, the utility model is described in further detail below.
With reference to Fig. 1, the anti-by-pass means of underground continuous wall connector, for being highly the construction of the diaphram wall of 30m, including
There are steel reinforcement cage and I-shaped steel joint 1, the steel reinforcement cage includes longitudinal reinforcement 2 and transverse steel 3 interconnected, steel reinforcement cage
Both ends and I-shaped steel joint 1 are welded to connect, and further include having galvanized steel plain sheet 4,4 side of galvanized steel plain sheet is welded in I-shaped steel joint 1
Wing plate end, galvanized steel plain sheet 4 becomes the additional wing plate of I-shaped steel joint 1, the nearly outside positioned at steel reinforcement cage, the width of galvanized steel plain sheet 4
Degree is 600mm, length is equal with I-shaped steel joint 1.
It is located at the I-shaped steel tank (referred to as outer groove) of the second stage of wall section for I-shaped steel joint 1, the present embodiment is used by junction block 5
It is blocked with the interim stifled column that sand packet section 6 is constituted, the length of the junction block 5 is 15m, sectional dimension is slightly less than I-steel and connects
First 1 slot inside dimension (940mm × 300mm), the sand packet section 6 are piled by multiple sand packets (every packet 20kg), sand packet section 6 and connector
The docking of 5 end of pipe becomes temporarily stifled column and is placed in the outer groove of I-shaped steel joint 1, and the height of interim stifled column is equal with I-shaped steel joint 1.
When carrying out construction of diaphragm wall using the utility model, the utility model is put into the phase slot section excavated
Interior, the then concreting in a phase slot section is during which, soft due to galvanized steel plain sheet 4, and concrete is by the side of galvanized steel plain sheet 4
Outwardly against to supporting patch cell wall, galvanized steel plain sheet 4 stops concrete to the outside of I-shaped steel joint 1 around flowing through the second stage of wall section in portion.
Construction period, on a small quantity around the concrete for flowing through I-shaped steel joint 1, what is be made of junction block 5 and sand packet section 6 is interim stifled
Column crams the outer groove for being located at the I-shaped steel joint 1 of the second stage of wall section, greatly reduces around the concrete for flowing through the second stage of wall section.
When the second stage of continuous wall groove segment is constructed, first junction block 5 is taken out, then excavate the second stage of slot section, sand packet section 6 and the second stage of slot section
It excavates while removing.
