The detachable steel casing is simple in structure, convenient to use, convenient to install and dismount and capable of being circularly utilized.
Description
Technical field
The utility model relates to the casing that a kind of castinplace pile is used, particularly the removable steel casing of a kind of variable cross-section bored pile.
Background technology
The steel casing is exactly in the process of carrying out hand excavated pile, because soil property is unstable, so the construction reinforced bar concrete guard wall exists larger difficulty to adopt the retaining wall of steel that the hole stake is protected, construction speed and safety are avoided affecting in the hole that prevents from collapsing.The steel casing be exactly two of a circle becoming with the iron sheet hoop according to the size of hole stake all be empty bucket.
The steel casing can be stablized hole wall, prevents the hole that collapses, and can also isolate surface water, starter, spud pile position, protection operation original ground etc.
The steel casing generally than the large 20-40cm in stake footpath, decide on the proterties of soil by buried depth, and the deviation of plan-position must not be greater than 5cm, and gradient is less than 1%.
Existing steel casing all is integral type, and it is not easy to dismounting and recycles.
The utility model content
The technical problems to be solved in the utility model provides a kind of removable steel casing of a kind of variable cross-section bored pile of being convenient to dismantle and can recycling.
For achieving the above object, the technical solution of the utility model is as follows:
The removable steel casing of a kind of variable cross-section bored pile, described steel casing is comprised of upper joint casing, middle joint casing and lower joint casing; Described steel casing is the inner hollow structure; Described middle joint casing is truncated cone-shaped, and the upper end of described middle joint casing and upper joint casing removably connect, and the lower end of described middle joint casing is fixedly connected with lower joint casing.
Preferably, the upper end of described middle joint casing is connected with upper joint casing by flange.
Preferably, weld mutually with lower joint casing the lower end of described middle joint casing.
Preferably, described steel casing adopts the steel plate spiral welded to form.
Preferably, the length of described upper joint casing is 6m, and internal diameter is Ф 1250mm, and wall thickness is 10mm.
Preferably, the internal diameter of described middle joint casing is Ф 800-1250mm, and wall thickness is 10mm.
Preferably, the length of described lower joint casing is 6m, and internal diameter is Ф 800mm, and wall thickness is 8mm.
Preferably, the side of described upper joint casing is provided with symmetrical preformed hole, is provided with the steel shoulder pole in the described upper joint casing, and the two ends of described steel shoulder pole are placed in the preformed hole.
By technique scheme, the beneficial effects of the utility model are:
