Description
Technical field
The present invention relates to concrete pit construction field, particularly a kind of pit shaft mould plate supporting device and its peace tear method open.
Background technology
In metro depot, the construction of parking lot concrete pit, due to being limited by inspection shaft working space, it is difficult to apply
In general form bracing system, it more can not meet and internal model dismounting operation carried out inside operating personnel's tripping in inspection shaft.
Two major classes are broadly divided into for cylindrical shape cast-in-place concrete structure, large cylinder-shaped structure mainly has hollow thin-wall
Pier, silo, chimney, deep-well pump house etc..The ratio of application is wide the columnar structured creeping formworks of more than 8m, two-sided sliding formwork, one side
Sliding formwork, the Turnover Form Construction Technology, common typified form supporting construction columnar structured below 8m.Middle-size and small-size thin wall cylinder-shaped structure
Main rain, sewage inspection well, bridge pad reserving hole etc..For this class formation using relatively common rainy, sewage inspection
Well combined steel, plank sheathing support system, bridge pad reserving hole are mainly molded work with pre-buried plastic conduit, coring etc.
Skill.
It can be seen that though cylindrical shape concrete structure construction technology at home and abroad has many application technology and plant equipment, however, basement
Well is most common due to operating environment, the limitation of operating space as metro depot, the drainage system underground structure in parking lot
Construction method, template system and do not apply to.
Analyzed by most common construction method, circulation material：The similar engineering hitherto seen is mainly with group
Steel, the construction method progress operation of plank sheathing progress internal model support are closed, internal model installation is installed according to " by lower from upper, staged and layered "
Principle, operating personnel carries out formwork reinforcement in layer inside deep-well, and internal model support system also necessarily turns into be arrived on worker
The unique passage and operating platform on ground.
Not only difficulty is big for such construction operation, and personnel's Zhi Li, dismounting template security context in small space is poor, disappears
Time-consuming is grown.Operating personnel is also same to be examined in face of the hot environment that the concrete heat of hydration is brought of going into the well again, part operation personnel synthesis
Consider above-mentioned factor, form removal of often no longer going into the well, and internal model is retained in deep-well, feel to also comply with reason.If well depth is not only
Waste of materials, and raindrop erosion template can bring the defects of blocking drainage channel, greatly increase construction in later period and maintenance cost.
Such method is only applicable to the construction of inferior grade temporary work, can not meet the matter of high-grade highway, high-speed railway, rail yard
Amount requires.
Analyzed by the input situation of live human resources：Conventional internal model support is carried out in small space, it is not only difficult
To ensure personal security, similarly it is difficult to ensure that the concrete quality of structure pours stabilization.Under normal circumstances, it is guarantee rolling stock section, stops
Large number of cylindrical shape concrete architecture quality and construction speed in parking lot, the multiple operations of substantial amounts of people's work point need to be put into while carried out
Excessive risk is vertical, form removal process, and manual work productivity ratio is extremely low, considerably increases construction cost.
The content of the invention
Technical problem solved by the invention is to provide a kind of pit shaft mould plate supporting device and its peace tears method, present invention dress open
