Description
Technical field
The present invention relates to the underground continuous wall construction technique field in foundation pit enclosure structure, and in particular to one kind is welded with peg
I-shaped steel joint.
Background technology
Subway station and basement in high rise building construction are required to perform vertical soil-baffling structure, vertical soil-baffling structure master at present
Have the forms such as drilled pile, diaphram wall, the stake of SMW engineering methods, steel sheet pile, cement mixing wall, when foundation ditch compared with it is deep, soil response is strong
When spending that relatively low, water level is higher, there is structure building on foundation ditch periphery, vertical soil-baffling structure uses diaphram wall mostly.Underground is continuous
Wall is typically to divide what wall section performed along foundation ditch periphery, typically first performs a phase diaphram wall section, waits a phase diaphram wall strong
After degree reaches design strength, then perform the second stage of diaphram wall section, a phase diaphram wall section and the second stage of diaphram wall section it
Between be provided with I-shaped steel joint, cross steel plate joint or fore shaft pipe joint etc..
Cross steel plate joint is made up of cross steel plate and slide type joint case, when to the integral rigidity or anti-of diaphram wall
Used when being impregnated with particular/special requirement, its advantage is：1) steel plate is provided among the joint, extends permeable blind ditch, leakage performance
Preferably；2) shear behavior is preferable；But its shortcoming is：1) process is more, and construction is complicated, and difficulty is larger；2) brush wall and removing wall section side
Wall mud has certain difficulty；3) anti-bending strength is undesirable；4) steel plate dosage is more, and cost is higher.
When diaphram wall uses I-shaped steel joint, it is necessary to abdomen to I-steel after the second stage of diaphram wall section grooving
Plate and wing plate carry out brush wall skin process native clearly.Be not in percolating water at I-shaped steel joint when in theory, using I-shaped steel joint
Problem.But in Practical Project, often occurs percolating water at I-shaped steel joint, its result will cause foundation ditch periphery place underground
Water level decreasing and surrounding buildings settlement cracking.Arranged so often also needing to perform extra sealing on the outside of I-shaped steel joint
(for example, mixing pile, high-pressure rotary jet grouting pile) is applied, duration and increase construction costs will certainly be extended by performing extra measures of preventing water.
If part of the diaphram wall as underground agent structure, it is necessary to permanent durable, the overall ne-leakage of structure.
The wall that each section of diaphram wall can meet design requirement, and composition each intersegmental attachment structure of diaphram wall is that underground is continuous
Wall system key core link.If helped at present using diaphram wall as agent structure exterior wall, it is necessary to be performed in joint area
Pilaster and measures of preventing water, it so can undoubtedly increase construction costs.
I-shaped steel joint percolating water has the reason for following aspect between causing diaphram wall：1) web of I-shaped steel joint and
Wing plate wall is locally stained with mudcake, and the clear mud of brush wall has mass defect；2) I-shaped steel joint bending resistance is low, the second stage of diaphram wall
The concrete of section only has bonding with I-shaped steel joint wall, and adhesive strength is relatively low, and I-shaped steel joint both sides pit earthwork excavates and branch
Support, which is set, inconsistent easily to be caused and is ftractureed between I-shaped steel joint and concrete；(3) contraction can be produced in course of hardening,
Gap can be produced between I-shaped steel joint and concrete.Therefore, I-shaped steel joint leakage problems between diaphram wall to be solved, are needed
To improve from the following aspect：1) the clear shale amount of I-shaped steel joint brush wall is improved, but the clear mud of I-shaped steel joint brush wall is under water
Carry out, can not check and monitor；2) bending resistance improved between I-shaped steel joint and the concrete of the second stage of diaphram wall section is strong
Degree；3) measures of preventing water is taken between I-shaped steel joint and concrete.
So how to improve anti-bending bearing capacity between underground I-shaped steel joint and the second stage of diaphram wall section concrete and resist
Seepage property, the clear shale amount of the I-shaped steel joint brush wall even cancellation clear bricklayer's's sequence of I-shaped steel joint brush wall is improved, put in ability
Technological difficulties in face of the engineers and technicians of domain.
The content of the invention
It is reasonable in design, make in view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of simple in construction
With the I-shaped steel joint for being easily welded with peg, it is not necessary to carry out the clear mud of I-shaped steel brush wall, I-steel is isolated with mud, ensure
I-steel cleans；I-steel web is welded with peg, and peg is anchored into the second stage of diaphragm wall section concrete, and joint anti-bending bearing capacity is high,
Joint non-deformability is strong, improves the impermeability of I-shaped steel joint, and practicality is stronger.
To achieve the above object, the technical solution adopted by the present invention is：It includes I-steel, peg and plugging plate and formed；
Two block wing plates of the described I-steel by one block of web and positioned at web both sides are welded；The two sides difference of described web
Be close to be located at a phase diaphram wall section and the second stage of diaphram wall, and a phase diaphram wall section steel reinforcement cage respectively with I-shaped
Two blocks of wing plates welding of steel；Described plugging plate is arranged in the groove by the second stage of diaphram wall side I-steel, and is blocked
The web of the groove of plate towards I-steel is set；The middle part of described web, ordered series of numbers is welded with by the second stage of diaphram wall side
Peg.
Further, described plugging plate is by bottom land steel plate, side steel plate, floor, rubber slab, top rubber plate, first
Top steel plate and the second top steel plate are formed；Wherein bottom land steel plate be arranged in parallel with web, and side steel plate be arranged in parallel with wing plate,
And set with wing plate in certain distance, one end of two blocks of side steel plates is welded with bottom land steel plate respectively；The second described top steel
Plate is located at the top surface of side steel plate, and is welded with side steel plate, and the second top steel plate is vertically arranged with bottom land steel plate, and and bottom land
Steel plate welds；First top steel plate is located at the top of the second top steel plate, and is set with the second top steel plate in certain distance, the
One top steel plate is vertically arranged with bottom land steel plate, and is welded with the medial surface of bottom land steel plate；Top rubber plate is folded in the first top
Between portion's steel plate and the second top steel plate；Two slat gum plates are folded between two blocks of side steel plates and two blocks of wing plates respectively, and rubber
The contact surface vulcanization of offset plate and top rubber plate connects；The medial shaft of described side steel plate is interval with polylith floor upwards,
And floor welds with bottom land steel plate and side steel plate respectively.
Further, the thickness of described rubber slab is more than the spacing between side steel plate and I-steel wing plate.
Further, described rubber slab is big by the thickness ratio other end of one end of bottom land steel plate.
Further, connected between described rubber slab and side steel plate by bolt and viscose glue.
Further, the bottom of described plugging plate, and it is provided with bottom end steel plate by the second stage of diaphragm wall one positioned at I-steel；Bottom
Hold steel plate to be welded respectively with web and wing plate, sealant sealing is used between plugging plate and bottom end steel plate.
Further, the outer top surface of described bottom end steel plate welds several nuts, and nut is provided with corresponding bolt.
