Specific implementation mode
As shown in Figure 1 and 2, the utility model discloses a kind of prefabricated open caisson elevator pits, it includes prefabricated lining rectangular cylinder
1, plain concrete bed course 2, arrangement of reinforcement bottom plate 3, drawknot ring muscle 4, shearing resistance groove 5, ground beam slab 6, buffer of elevator 7, rubber water-proof item 8,
The prefabricated lining rectangular cylinder 1 is arranged in elevator pit, and the element concrete bed course 2 is arranged in the bottom of prefabricated lining rectangular cylinder 1,
The corresponding arrangement of reinforcement floor level in the inside of prefabricated lining rectangular cylinder 1 offers shearing resistance groove 5, poured after the ground beam slab 6 and with it is prefabricated
1 top of borehole wall rectangular cylinder is connected as entirety, and the buffer of elevator 7 is vertically disposed at arrangement of reinforcement bottom plate 3.
Prefabricated lining rectangular cylinder 1 can be prefabricated in ex situ in the utility model, not by field condition and time restriction, waterproof
It is required that thickness of shaft wall >=250mm；In practical application, when elevator pit planar dimension is larger and when pit is deeper, construction period
Horizontal bars can be added in hole temporarily to support, to bear soil pressure.
Shearing resistance groove 5, depth can use 50mm, highly equal with 3 thickness of arrangement of reinforcement bottom plate, can in prefabricated lining rectangular cylinder 1
Fixed polystyrene batten is as template, convenient for being convenient for being formed shearing resistance groove 5；
Twice rubber water-proof item 8 is set in shearing resistance groove 5, to prevent in Groundwater infiltration elevator pit；
After 1 open caisson to designed elevation of prefabricated lining rectangular cylinder, hole subsoil should be tamped smooth, then pour blinding concrete,
Arrange plain concrete bed course 2；
Drawknot ring muscle 4, throws away from prefabricated lining rectangular cylinder 1, in use as connection reinforcing bar, in the construction process
Hanging ring use is can be used as, but should take measures to avoid by stretch bending in lifting construction；
Maintenance cat ladder need to be arranged when being more than 1.6m in elevator pit depth, built-in fitting can be arranged in prefabricated lining or beat temporarily
Hole anchors after using anchor bolt.
