Description
Technical field
The invention belongs to diaphram wall body construction device field.It is more particularly related to one kind is in underground even
What continuous surface of wall poured liner hangs mould suspension device and construction method.
Background technology
At present diaphram wall is widely used in Analysis of Suspension Bridges ' Anchorage, subway station etc. and constructs with reference to the deep basal pit of liner supporting
Thing.Using the reverse construction of from up to down placement layer by layer more than reinforced concrete structure liner supporting.In Coastal Area of Guangdong Province stream
Plasticity sludge soft stratum, liner pours the subject matter facing is how to process liner to pour basis, and its technical barrier includes:
1st, deep ＆ thick silt layer engineering geology extreme difference, the new mud that excavates is in liquid-plastic state, and characteristic load bearing capacity is less than
40kpa, when liner pours, total subsidence is difficult to control to.
2nd, saturation mud moisture content is high, often assembles in lining base and descends open fire in large quantities, cause substrate during excavation of foundation pit
Difficult treatment.
3rd, be reduce foundation pit deformation, pattern foundation pit supporting structure to dig soon soon to support as principle, the operation such as liner reinforcing bar binding, formwork erection
Efficiency of construction need to be ensured.
The soft base substrate treating method of existing liner changes for excavation to be dosed solid, is become by the sedimentation that ballast test draws substrate
Shape parameter, determines to change and fills out area and change and fill out depth.Program strengths and weaknesses analysis are as follows:
1st, excavate to change and fill out the drainage problem that can alleviate basis to a certain extent；The strong mud of deep stream plasticity is controlled
Foundation settlement effect processed is undesirable.
2nd, excavate to change in mud and fill out that workload is big, low construction efficiency, do not meet the principle that pattern foundation pit supporting structure digs soon soon supports.
In sum, the liner bed die in coastal sludge soft soil layer is reinforced not yet effective method.
Existing hang mould suspension device all using suspension type what diaphram wall body surface face poured liner, that is, adopt two
Hanging reinforcing bar is fixed it is contemplated that diaphram wall body is a loop configuration, if each piece of end template is adopted to end template
Hung with two hanging reinforcing bars, construction cost is a huge burden, therefore to the improvement hanging mould suspension device, subtracts
Few construction cost is an extremely urgent problem.
Existing diaphram wall body surface face pour liner hang mould suspension device construction when, need added from foundation ditch
If scaffold, workman stands in and is constructed on scaffold, and so resulting in workman needs movable Scaffold ability displacement, and moves
The process of scaffold will necessarily slow down construction speed, and indirectly increased the danger of workman.
Content of the invention
It is an object of the invention to solving at least the above and defect, and provide the advantage that will be described later.
A further object of the invention be a kind of hang mould suspension device what diaphram wall body surface face poured liner, pass through
It is provided with the powder-spray pile supporting described end template in described end template near a side-lower of diaphram wall body, in described end template
Side away from diaphram wall body is provided with the hanging reinforcing bar hanging described end template；So that hanging mould suspension device by merely hanging
Hanging become half support semimounted structure, decrease construction cost.
A further object of the invention is by being provided with multiple trivets, described trivet in bell-mouthed outside
With described side form bolt, two neighboring described trivet is horizontally disposed with scaffold board, pours as a concrete that suspended on
Build platform, alleviate the difficulty of construction of construction worker.
It is a still further object of the present invention to provide one kind is using hanging mould suspension device in diaphram wall body surface face pours
The method of lining, by digging foundation ditch, leveling powder-spray pile, hanging the steps such as hanging reinforcing bar, decreases the engineering time, reduces construction difficult
Degree.
