Description
Technical field
This utility model relates to a kind of cast-in-place open caisson formwork system.
Technical background
Open caisson application in Practical Project gets more and more, but, owing to open caisson construction is affected by the complexity etc. of the multiformity construction management of the uncertain construction environment of geological state so that the construction of open caisson has the feature of uncertainty.Meanwhile, mould in caisson wall, during due to concrete construction, affected by the lateral pressure of concrete, so beating tightr and tightr, will not produce burst apart, be not easy to produce spillage.But the necessary firm supporting of the interior mould of open caisson, to prevent bigger deformation.
Traditional open caisson formwork uses steel pipe to set up the framed bent support system as template, and this technique uses steel pipe quantity big, and the cycle of setting up is long, and the defects such as Form floating, swollen mould, concrete walls surface evenness, perpendicularity difference easily occurs, and construction quality is difficult to ensure that.Open caisson inner side template installs needs to set up from top to down scaffold, due to the excavation of the internal soil body of open caisson, need that repeats to set up and remove scaffold, and along with the excavation of the soil body in well, underground construction is more complicated, sets up scaffold for sunk well without bailing construction inside more difficult；Open caisson outboard template is also required to repeat assembling and disassembling, and efficiency of construction is low.
In consideration of it, need a kind of Stability Analysis of Structures of invention at present badly, be prone to dismounting, easy to operate, need not in well set up scaffold and realize template move horizontally, be suitable for differing heights open caisson formwork system.
Summary of the invention
The purpose of this utility model is to provide a kind of Stability Analysis of Structures, is prone to dismounting, easy to operate, need not set up scaffold from bottom to top and realize template move horizontally, be suitable for differing heights open caisson formwork system in well.
For achieving the above object, this utility model have employed techniques below scheme:
A kind of cast-in-place open caisson formwork system, it is characterised in that: include poppet, inner side template, outboard template, screw rod, bearing diagonal, horizontal support, movable bar and double-pole scaffold；Template-setup poppet at cutting shoe, arranges spacing flitch on the left of poppet；Borehole wall inner side template and outboard template to being pulled together, screw rod are provided with sealing piece by screw rod；Inner side template arranges bearing diagonal, and bearing diagonal one end is fixed in borehole wall inner side template, and the other end supports on the ground；Outboard template arranges horizontal support, and horizontal support one end is fixed on outboard template, and the other end is fixed on movable bar；Movable bar is connected with the cross bar of double-pole scaffold；At steel reinforcement cage upper position, pre-buried pvc pipe is set.
Further, screw rod is three joints, and middle part one joint is stayed in the borehole wall, and two ends screw rod is connected with middle part one joint by taper bolt respectively, arranges 2 steel pipes respectively between borehole wall inner side template, outboard template and three row fasteners.
Cross bar one end of double-pole scaffold is groove structure, and movable bar is arranged in groove and is bolted, and after removing bolt, movable bar can move in groove.
This utility model has following feature and a beneficial effect:
(1) after first segment open caisson construction, without again dismounting, only need to remove Screw arbor with nut at both-ends, outboard template can move horizontally laterally and be fixed on double-pole scaffold, treating that well sinking postpones to specific bit and be fixed formwork again, construction period substantially shortens.
(2) the removable split bolt used is three joints, middle part one joint is stayed in body of wall, interior band seal ring, two ends screw rod is connected with middle part one joint by taper bolt respectively, after form removal, two ends screw rod and taper bolt can be removed and recycle, and has easy accessibility, saves material, reduce operation, the feature of reduction of erection time.
(3) carry out skewed horizontal load during cast-in-place open caisson formwork, only set up scaffold in double-pole scaffold coordinates than conventional construction method in open caisson lateral wall and carry out formwork or add level land diagonal brace, there is higher stable and property safety.

Detailed description of the invention
Just being not repeated in these enforcements such as present embodiment welding for steel structure technique, bolt connection construction technique, template-setup technique and concrete pouring construction technique, emphasis illustrates that this utility model relates to the embodiment of structure.
Fig. 1 is this utility model cast-in-place open caisson formwork system first segment open caisson formwork erecting structure schematic diagram.With reference to shown in Fig. 1, this utility model cast-in-place open caisson formwork system specifically includes that poppet 4, inner side template 7, outboard template 8, screw rod 11, three row fastener 12, taper bolt 13, bearing diagonal 14, steel pipe 15, horizontal support 16, movable bar 20 and double-pole scaffold 17.
With reference to shown in Fig. 1, before open caisson template construction, bottom open caisson, first lay one layer of sand-gravel cushion 1, a laminin concrete cushion 2 is poured on sand-gravel cushion, arranging backing plate 3 bottom cutting shoe 6, at cutting shoe 6, formwork uses poppet method, poppet 4 to be positioned on backing plate 3 by spacing flitch 5.
