Technical field
The present invention relates to dock engineering technical field, a kind of especially a kind of foundation pit enclosure wall suitable for building dock
Counterfort wing wall waterproof curtain construction method.
Background technique
Currently, the water-stop curtain of the buttress type wing wall for dock engineering, common pattern have single steel sheet pile, single company
Continuous overlapped high-pressure rotary jet grouting pile, or common grout curtain pattern etc. in batholith.Since the water-stop curtain of these patterns is logical
Be with interim curtain needed for excavation of foundation pit often separate, once after dock engineering, setting when also removing excavation of foundation pit
Temporary leaking water curtain.
The Water sealing in dock curtain of the prior art is built, long construction period, and project cost is high, not only increase engineering cost and
Labour, but also waste a large amount of construction material.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art and the counterfort wing wall of a kind of foundation pit enclosure wall that designs stops
Water curtain construction method, the foundation pit enclosure wall for using steel-pipe pile to combine with steel sheet pile is the sealing curtain of excavation of foundation pit and counterfort wing wall
Curtain structure saves a large amount of construction materials, substantially reduces and apply so that excavation of foundation pit does not have to reset one of temporary leaking water curtain
The work period reduces project cost, and simple and reasonable for structure, sealing performance has fully met the requirement of dock buttress type wing wall, reliably
Property it is high.
The object of the present invention is achieved like this：A kind of counterfort wing wall waterproof curtain construction method of foundation pit enclosure wall,
Its main feature is that foundation pit enclosure wall uses steel-pipe pile and steel sheet pile assembled wall for the water stop curtain structure of buttress type wing wall, it is specific
Construction carries out in the steps below：
（One）Foundation pit enclosure
The enclosure wall that foundation pit enclosure is composed using steel-pipe pile and steel sheet pile, the enclosure wall by steel sheet pile two sides with
Half steel sheet pile steel-pipe pile adjacent thereto is welded；Half steel sheet pile side is connect by fore shaft with steel sheet pile, another
Side and steel-pipe pile weld；The steel-pipe pile bottom application work piles set into rock, bored concrete pile one end insertion in weathered rock formation, the other end
It protrudes into the steel pipe of steel pipe pile bottom.
（Two）Excavation of foundation pit
It is supported in first of foundation pit for going along with sb. to guard him the top beam of coping construction reinforced bar concrete and being connect with top beam,
Then the earth excavation in foundation pit is carried out, enclosing for the second armored concrete in the middle part of enclosure wall of then constructing is enabled and enabled with enclosing
The foundation pit second of connection supports, and continues the earth excavation in foundation pit.
（Three）, wing wall bottom plate and enclosure wall sealing
Construction wing wall bottom plate after earth excavation to designed elevation, and the enclosure wall of wing wall floor rear and foundation pit is used and is stopped
Water steel plate carries out the patching that node connects with anchor bar, and the steel plate for sealing water is that one end is bonded retaining wall and and steel plate
Stake and steel-pipe pile welding, the other end are then anchored in the deformed steel flats in wing wall bottom plate；Described anchor bar one end is welded in steel pipe
In stake or steel sheet pile, the other end is anchored in wing wall bottom plate.
（Four）, foundation pit backfill
After the completion of base pit engineering and bottom slab, removes the support of foundation pit second and enclose order, then construct counterfort panel and rib
Backfilling of earthwork on rear side of plate and buttress type wing wall, finally by first of supporting removal of foundation pit, the enclosure wall of foundation pit is then to help
The permanent leaking water curtain structure of wall type wing wall.
The present invention has structure simple compared with prior art, and project cost is low, easy for construction, and construction quality reliably waits spies
Point is particularly suitable for the water-stop curtain using foundation pit support method construction buttress type wing wall.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is assembled wall structural schematic diagram；
Fig. 3 is the A node enlarged diagram of Fig. 1；
Fig. 4 is the B-B the schematic diagram of the section structure of Fig. 3.
Specific embodiment
Refering to attached drawing 1, the present invention is made of buttress type wing wall 1 and foundation pit enclosure wall 2, and the foundation pit enclosure wall 2 uses steel
Tubular pole 11 and 13 assembled wall of steel sheet pile are the water stop curtain structure of buttress type wing wall 1；At the top of the foundation pit enclosure wall 2 be equipped with
The top beam 5 of first of foundation pit support, 6 connection, middle part enable 7 equipped with enclosing for connecting with foundation pit second support 8；The buttress type
The wing wall bottom plate 9 of wing wall 1 is connect by steel plate for sealing water 15 with the assembled wall of steel-pipe pile 11 and steel sheet pile 13；11 bottom of steel-pipe pile
Portion is equipped with bored concrete pile 4, weathered rock formation in the insertion of 4 one end of bored concrete pile, and the other end is embedded in 11 bottoms of steel-pipe pile.
Refering to attached drawing 2, the steel-pipe pile 11 is with 13 assembled wall of steel sheet pile by 13 two sides of steel sheet pile with half steel sheet pile 12
Steel-pipe pile 11 adjacent thereto is welded, and 12 side of half steel sheet pile is connect by fore shaft 14 with steel sheet pile 13, another
Side and steel-pipe pile 11 weld.
Refering to 3~attached drawing of attached drawing 4, described 15 one end of steel plate for sealing water is anchored in wing wall bottom plate 9, and the other end is bonded described group
It closes wall and is welding with steel sheet pile 13 and steel-pipe pile 11, the wing wall bottom plate 9 is equipped with several anchor bars 16, anchor bar
16 weld with steel-pipe pile 11 or steel sheet pile 13.
The present invention is performed such construction：The assembled wall for carrying out steel-pipe pile 11 and steel sheet pile 13 first is constructed, in steel
13 bottom application work piles set into rock 4 of tubular pole, decomposed rock certain depth in the insertion of 4 one end of bored concrete pile, 4 other end of bored concrete pile protrudes into steel
Certain depth in the steel pipe of 11 bottom of tubular pole.The top construction reinforced bar concrete of foundation pit enclosure wall 2 top beam 5 and with top
First of the foundation pit support 6 that collar tie beam 5 connects, then carries out earth excavation；Then construct second armored concrete enclose enable 7 with
And 8 are supported with the foundation pit second for enabling 7 connections is enclosed, earth excavation is carried out to designed elevation.Finally construction wing wall bottom plate 9, wing wall
9 rear side of bottom plate carries out node connection, wing wall bottom plate 9 using the steel plate for sealing water 15 of anchor bar 16 and abnormity with foundation pit enclosure wall 2
A fixed gap is reserved between steel-pipe pile 11, welds elongated steel plate for sealing water on the wall combined with steel sheet pile 13 of steel-pipe pile 11
