Utility model content
The utility model provides a kind of string pipe of building for deep foundation ditch concrete, chute combined system, solve that surrounding deep foundation pit place is narrow cannot set up chute, and mass concrete is difficult to carry out the technical problem of continuous placing.
The utility model solves the technical scheme that its technical problem adopts:
This string pipe of building for deep foundation ditch concrete, chute combined system, described string pipe is made up of steel pipe and girth member, steel pipe is arranged at intervals with one eighth bend section along short transverse, and straight length above one eighth bend section is welded with girth member, steel pipe bottom forms string pipe discharging opening with vertical incision, and string pipe discharging opening is relative with chute start position;
Described chute comprises chute cell body, chute bracing frame and pavement, described chute cell body forms by laying iron sheet panel in flute profile plank sheathing, chute cell body bottom and both sides are supported on chute bracing frame by flitch, and described pavement is erected on the chute bracing frame of chute cell body one side.
Described girth member is steel plate or channel-section steel.
The gradient of described chute cell body is 1:2.5.
On the chute bracing frame of described chute cell body below, hang with safety net.
On the adjacent chute bracing frame in described pavement, hang with Dense mesh screen.
Described pavement is made up of the skirting board of the wooden springboard tiling and wooden springboard both sides.
Described pavement interval 300mm is furnished with tread plate.
Described chute also comprises the baffle plate that dams, described in the baffle plate that dams form with flitch, vertical baffle plate and detachable plank sheathing by damming, vertical baffle plate is connected with detachably plank sheathing is vertical in chute cell body, dams and is laterally connected in the vertical baffle plate back side with flitch.
The beneficial effects of the utility model are as follows:
It is curved that string pipe of the present utility model is established 45 degree every certain altitude, to ensure that concrete can not emanate because of freely falling body. String pipe has carried out Design of Reinforcement at the elbow position that is hit, and has improved string pipe service life.
Chute cell body of the present utility model adopts plank sheathing scene to be made by carpenter, is fixed on steel tube frame. Chute bracing frame arranges pavement, can ensure that workman observes the normal situation about using of chute in casting process, and keep in repair in the time that chute breaks down. When chute dams, can adopt the baffle plate that dams, the baffle arrangement that dams is simple, for convenience detach.
The combined system that string pipe of the present utility model adds chute efficiently solves surrounding deep foundation pit narrow field and cannot set up the problem of chute, has improved speed of perfusion, thereby saves the duration, ensures the continuous placing of mass concrete, has ensured construction quality.
