Description
Technical field
The present invention relates to Construction Technology field, particularly relate to dismountable relay well.
Background technique
Long-distance pipe jacking refers to that the continuous distance advanced of each section is all at the jacking construction of more than 200m-300m, reached at the 800m-1500m had.Because one-time continuous advance distance is longer, to construct many differences with ordinary topping pipe, although long-distance pipe jacking adopts mud lubrication measure can reduce jacking frictional resistance, no matter what degree is top power reduce to, be subject to certain restrictions after all.In jack-in process, when back intensity or pipe bearing capacity are restricted, whole jacking section can be divided into some sections and adopt relay jacking, the object extending apex distance can be reached.
Relay well is the relay jacking working room arranged in the middle of the jacking pipeline section, and this inside working chamber installs oil cylinder, the pipeline section jacking before undertaking between interruption, and oil cylinder advances above after pipeline section, and oil cylinder advances relay well pipeline section below again.Existing steel pipe relay well, carries out anti-corrosion measure inconvenience after construction completes.After jacking construction completes, inner oil cylinder and fixing device are not quick detachable.After dismounting completes, do anticorrosive work amount excessive, and antiseptic effect is bad, after of long duration, just there will be obscission.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of concrete pipe of convenient disassembly anticorrosion relay well.
The object of the present invention is achieved like this: the anticorrosion relay well of concrete pipe, comprise front tube assembly, rear end pipe assembly, O shape apical ring, the front end of rear end pipe assembly is plugged on the rear end of front tube assembly, in the periphery, front end of rear end pipe assembly, step is set, O shape apical ring is arranged on the step of the rear end pipe assembly in front tube assembly, oil cylinder back bracket is connected in described front tube assembly, oil cylinder back bracket arranges some oil cylinders, every platform oil cylinder is fixed in oil cylinder back bracket respectively by oil cylinder fixed plate, the telescopic end of every platform oil cylinder is connected with described O shape apical ring respectively, pumping plant is connected in rear end pipe assembly, described O shape apical ring comprises six groups of arc upper frames to 20 groups of same structures, and described oil cylinder back bracket comprises the identical curved support frame of six groups to 20 groups structures.
O shape apical ring is divided into the arc upper frame of some groups of same structures by the present invention, oil cylinder back bracket is divided into the identical curved support frame of some groups of structures, after having constructed, inner body is dismantled, transport, dismounting part (O shape apical ring and oil cylinder back bracket) is divided into some equal portions, to reduce weight during dismounting.
As improvement of the present invention, often organize curved support frame and comprise outer arc plate, base plate, fixed plate, two pieces of connecting plates respectively, outer arc plate is arc, base plate and fixed plate are welded on outer arc plate respectively, and fixed plate is arranged on the rear side of base plate, and fixed plate arranges oil cylinder mounting groove, two pieces of connecting plates are welded on the two ends of outer arc plate respectively, connecting plate on adjacent two pieces of outer arc plates is bolted, and described oil cylinder is arranged in oil cylinder mounting groove, and the cylinder barrel of oil cylinder is connected with base plate.All adopt bolt welding to fix with anchor ear on barrel because former oil cylinder is fixing, vibration time during construction owing to running, generation fixing bolt welding ends comes off and causes oil cylinder to damage sometimes, curved support frame is provided with the mounting groove of oil cylinder, can well fix after oil cylinder is put into, there will not be the phenomenon that drops, install straightness accuracy better, jacking efficiency is higher.
In order to strengthen the intensity often organizing curved support frame, often organize curved support frame and also comprise stiffening rib respectively, one end of stiffening rib is welded with fixed plate, the other end welds with base plate.
Improve further as the present invention, often organize arc upper frame and comprise the first coaming plate, the second coaming plate, gusset, inner flange, two outward flanges respectively, first coaming plate is arc, inner flange is welded on the rear side in the first coaming plate, two outward flanges are welded on the both sides, front and back outside the first coaming plate respectively, second coaming plate is arc and is arranged on the outside of the first coaming plate, the both sides, front and back of the second coaming plate are welded with corresponding outward flange respectively, gusset is welded on the outside of the second coaming plate, and the rear and front end of gusset is welded with corresponding outward flange respectively.
Improve further as the present invention, bird shape seal ring is set between described front tube assembly and rear end pipe assembly; Described front tube assembly comprises pipe in front spring outer tube and front cement, and in front cement, pipe is connected in front spring outer tube; Described rear end pipe assembly comprises pipe in rear steel plate outer tube and rear cement, and in rear cement, pipe is connected in rear steel plate outer tube.Adopt the mixing tube (front tube assembly and rear end pipe assembly) that steel plate cement makes, just completely anticorrosion before jacking, dismantled by inner body after having constructed, transport, after having dismantled, two concrete pipes are merged by fitting tight circle.Do not need to carry out anticorrosion, good sealing effect.Decrease greatly corrosion-resistant workload, improve construction period.
