Description
Technical field
The present invention relates to jacking construction field, more particularly to a kind of jacking construction end-protecting device and jacking construction are used
Attachment means between steel pipe.
Background technology
Jacking construction is exactly non-excavating construction method, is a kind of piping laying construction technology do not excavated or excavated less.
Construction by pipeline jacking method is exactly to overcome the frictional force of pipeline and surrounding soil by means of pushing up power caused by jacking device in working pit,
Pipeline is headed into soil by the gradient of design, and the earthwork is transported.One section pipe is completed to head into soil layer and then lower double section tube
Son continues jacking, and the pipe used in reality is divided into pipe of concrete either steel pipe, and its principle is by means of main top oil cylinder and pipe
Between road, the thrust such as relay well, pipe is advanced in reception hole always out of working pit through soil layer, pipe is just embedded in two holes
Between.
But for steel pipe, generally use jacking mechanism acts directly on the end of steel pipe in work progress, if steel pipe
When length spelling knot length is longer, the active force of jacking mechanism also can be bigger, the end of steel pipe may be caused to deform, to rear
Continuous connection between steel pipe and steel pipe brings inconvenience.
The content of the invention
It is an object of the invention to provide a kind of jacking construction end-protecting device, and it has in jacking construction, protects steel
The advantages of end shape of pipe.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of jacking construction end-protecting device, including be made up of base, outside break iron and inner side break iron for being buckled in steel pipe
The U-lag of end, U shapes groove structure annular in shape and openings of sizes are equal to the wall thickness of steel tube end part, and the base is away from steel pipe
Side be provided perpendicular to the plane in length of steel pipe direction, for applying the power along length of steel pipe direction.
By using above-mentioned technical proposal, in use, staff is arranged on end-protecting device the steel pipe of most end
Between jacking mechanism, the end of steel pipe is buckled in U-lag, two side walls of U-lag is against the outboard sidewalls of steel pipe, is strengthened
The structure of steel tube end part, the plane to steel pipe is provided with base, for the end for assigning to steel pipe power, makes steel pipe end
Uniform force, so as to protect the structure of steel tube end part, reduce deformation.
The present invention is further arranged to：The base is cyclic structure and rectangular cross-section, and Ring Width is more than steel pipe
Wall thickness.
By using above-mentioned technical proposal, base is arranged to the cyclic structure of square-section, and square-section can increase bottom
The bearing capacity of seat, the flexural factor of section is larger, ensures base self structure intensity, reduces because of base intensity deficiency, causes to steel
The disturbance of tube end.The width of annular is more than the wall thickness of steel pipe, increases the contact area between base and jacking mechanism, so as to
Make the stability of base and the jacking mechanism point of application, prevent it from shifting.
The present invention is further arranged to：The base is arranged to hollow-core construction.
By using above-mentioned technical proposal, base is arranged to hollow-core construction, is influenceing understructure stability less as far as possible
In the case of, to reduce the weight of protection device, staff is eaily picked up protection device in operation.
The present invention is further arranged to：The inner side break iron is tubular structure and is fixed on base close to one end of steel pipe,
In inner side, the inwall of break iron is provided with multiple reinforcements and is supported on base.
By using above-mentioned technical proposal, multiple reinforcements are provided between inner side break iron and base, reinforcement is used for
Transmit and the power away from external diameter is distributed on base to inner side break iron, the power for being subject to base is delivered to the power to steel pipe jacking, protects
Structure between river bottom protection seat and inner side break iron, the structural stability of enhancing inner side break iron.
The present invention is further arranged to：The base is fixed with fixed seat in the plane away from steel pipe side, fixed seat connects
It is connected to jacking mechanism, jacking mechanism is oil cylinder, output end of the fixed seating in oil cylinder.
By using above-mentioned technical proposal, fixed seat is fixed with base, and is enclosed on the output end of oil cylinder, is carrying out oil cylinder
During stretching motion, fixed seat is moved can together with output end, so as to which staff need not be during steel pipe be changed frequently
Take, reduce the labor intensity of staff.
The present invention is further arranged to：Fixing screws are provided with the fixed seat.
By using above-mentioned technical proposal, increase the output end that fixing screws make fixed seat be fixed on oil cylinder in fixed seat,
Reduce because when the extruding force of the end of end-protecting device and steel pipe is excessive, cause fixed seat not remove, make staff
, can be directly by oil cylinder end-protecting device after fixed seat is fixed on oil cylinder output end if relatively elaborate using removing by hand
Remove.
The purpose of the present invention also provides attachment means between a kind of jacking construction steel pipe, and it has in jacking construction, protects
The advantages of protecting the shape of steel tube connection head.
Attachment means between a kind of jacking construction steel pipe, including be made up of outer side connecting plate, connection plate inside and connecting plate
