Abstract
The utility model discloses a device for installing a large-size concrete cylindrical work piece by vibration driving. The device comprises a vibration machine, a vibration head and a vibration coupling rod arranged therebetween. The utility model is characterized in that the vibration machine is positioned on the top of the cylindrical work piece, the vibration head is arranged at the bottom of the cylindrical work piece and threadedly connected with the vibration coupling rod which is inserted into a through hole on the wall of the cylindrical work piece, with a vibration-isolating ring being arranged between the vibration coupling rod and the inner wall of the through hole. The vibration machine drives the vibration head to vibrate by the vibration coupling rod, to loosen the foundation soil under the cylindrical work piece, and the cylindrical work piece sinks into the loosened soil by self weight. The utility model is adapted to install large-size concrete cylinders without needing pre-stressed structure and can reduce the loss of vibration energy and reduce the construction costs.
Description
Technical field
The utility model relates to a kind of bottom and implements the device that vibration-sunk is installed large-sized concrete cylindrical structure.Belong to the supporting erecting device that sinks to installing large-sized concrete cylindrical structure in ocean, harbour water construction and the road and bridge engineering field.
Background technology
At present, large-sized concrete cylindrical structure to be installed in the foundation soil body, enforceable have three class methods: the one, excavate out foundation ditch, cylindrical structure is put into the hole, backfill, or the soil body that hollows out bottom cylinder interior and the barrel again makes it, and this class methods engineering quantity is big, length consuming time, the expense height; Another kind of method is to add ballast in cylinder top, and as vacuum ballast and Water Ballast etc., the degree of depth that these class methods are sunk cylindrical structure is limited, and off normal is restive and adjustment; The 3rd class methods are to make the cylindrical shell vibration, destroy around the tubular construction and the soil body of bottom, cylinder is sunk, this method requires cylindrical shell can bear bigger vibrating load and needs cylindrical shell is made prestressed structure at present, and this method energy consumption is big, and vibratory equipment requires to have bigger power.
Summary of the invention
The purpose of this utility model is to provide a kind of bottom to implement the device that vibration-sunk is installed large-sized concrete cylindrical structure.This device can sink to large-sized concrete cylindrical structure in the mounting foundation soil in easy mode, and operating expenses is low.
For achieving the above object, the utility model is realized by following proposal.At the large-sized concrete cylindrical that gives the vertical through hole that makes on the barrel, adopt mainly by bobbing machine, vibration head and the vibration coupling bar between them constitute the bottom and implement the device that vibration-sunk is installed large-sized concrete cylindrical structure, it is characterized in that, at the cylinder top bobbing machine is set, in the cylinder bottom vibration head is set, the vibration coupling bar passes through hole, and connect with vibration head with threaded connection mode, between the through-hole wall two vibration isolation circles are set at least on vibration coupling bar and the barrel.
Above-mentioned vibration head for have a same radius with cylinder and width greater than the annulus piece of barrel, the bottom surface of annulus piece is the cutting edge arc.
Above-mentioned a bobbing machine and a vibration head are connected by two vibration coupling bars at least.
With the utility model large-sized concrete cylindrical structure sink to be installed, unnecessary cylinder to be made prestressed structure, the vibration energy consumption is little, and operating expenses is low.
Description of drawings
Fig. 1 is at the vertical section of large-sized concrete cylindrical structure layout schematic diagram of the present utility model.
Fig. 2 is the floor map of Fig. 1.
1 is bobbing machine among the figure, and 2 for connecting spring, and 3 are the vibration coupling bar, and 4 are the vibration isolation circle, and 5 is nipple, and 6 is vibration head.
The specific embodiment
The vibratory equipment of sinking cylindrical structure shown in the drawings is made of the quadruplet vibrational system, the cylinder bottom is four independently vibration head, four independently bobbing machines are arranged at the top, each bobbing machine links by two vibration coupling bars and a vibration head, and cylindrical structure connected them before sinking and installs.Bobbing machine makes the vibration head vibration by the vibration coupling bar, destroys the soil body of cylindrical wall bottom.Because bobbing machine and vibration head all connect by flexure spring with cylindrical structure, when bobbing machine and vibration head vibration, excessive vibrational energy can be delivered on the cylindrical structure, cylindrical structure just can not be subjected to excessive vibrating load effect, the slight vibration of cylindrical structure can be destroyed the bonding of the barrel and the soil body simultaneously, and the native frictional resistance that is subjected on the barrel is reduced.Because vibration, after the resistance of cylindrical wall bottom and cylindrical wall surrounding soil reduced, cylindrical structure will sink.In the process that cylindrical structure sinks, the degree of skewness that the real-time monitored cylindrical structure sinks, the unlatching and the oscillation intensity of the vibrational system by the control different azimuth, the degree of skewness of sinking with regard to controlled rounding tube.After cylinder sinks to putting in place, disconnect the connection of vibration coupling bar and vibration head, bobbing machine and vibration coupling bar are taken out, but vibration head can't be taken out.
