Abstract
The invention relates to a relay device of a flexible joint steel structure. The relay device comprises a steel socket, an outer sleeve, jacks, a sealing ring, a socket ring and a socket, wherein the outer sleeve and the socket are coaxially arranged, the socket ring and the socket are coaxially and fixedly arranged, the jacks are uniformly installed on the inner edge of the outer sleeve between the socket and the steel socket in the radial direction, a front buffering cushion is installed between the front end face of each jack and the steel socket, and a back buffering cushion is installed between the back end face of each jack and the socket; and a sealing recess matched with the bellmouth of a concrete pipe is formed in the outer edge of the front end of the socket ring. The relay device is characterized in that an annular rib plate is welded in the socket ring. The device is installed at certain position of a once jacking pipe to divide the segment of the once jacking pipe into a plurality of propelling sections, in a jacking process, a plurality of relays propel the pipe for a small segment of distance in sequence, and a main jacking oil cylinder propels the pipe in the last section, so that the design is scientific and reasonable.
Description
Technical field
The invention belongs to the fields such as municipal engineering, public waterworks, project of South-to-North water diversion, gas works, communication engineering, relate to the push pipe relay well of long distance or extra long distance jacking construction, especially a kind of flexible joint steel structure relay well device.
Background technique
Long-distance pipe jacking refers to all jacking constructions more than 200m-300m of the continuous distance that advances of each section, reached at the 800m-1500m that has.Because the one-time continuous advance distance is longer, with the ordinary topping pipe construction many differences are arranged, also just have factors has restriction to long-distance pipe jacking effect.And to the research of long-distance pipe-jacking construction, namely study these differences and seek to solve the way of multiple restriction.Although long-distance pipe jacking adopts the mud lubrication measure can reduce the jacking frictional resistance, no matter what degree is top power reduce to, is subject to certain restrictions after all.In jack-in process, when back intensity or pipe bearing capacity are restricted, whole jacking sections can be divided into some sections and adopt the relay jackings, can reach the purpose that prolongs apex distance.
Relay well is the relay jacking working room that arranges in the middle of the jacking pipeline section, and inner several relaying jack of installing in this working room are undertaken pipeline section jacking before between interruption.After interrupting jack propelling front pipeline section, main pipeline section of pressing jack to advance again back between interruption, the method for this kind segmentation relay jacking is called and interrupts the indirect force jacking.At present in all jacking constructions, the concrete pipe push pipe adopts two kinds of methods to carry out jacking construction mostly: 1, not prosperous at underground water even adopt this kind method to construct without underground water more; 2, adopting many methods is that working pipe adopts undergauge one segment distance, decides according to jack stroke between interrupting, and diameter dimension is changed by the height of the wall thickness of sleeve and rubber seal.Owing in jacking construction, mostly adopting flexible joint steel joint socket, so the diameter dimension of concrete pipe such as the requirement of its relay well working pipe are less in the diameter dimension variation, sleeve is all right with cooperating of rubber seal, and sealing effect is all right.When making working pipe, pipe die needs to change, the pipe die manufacturing itself have deviation, but because sleeve is back and forth frequently flexible at work with seal ring, simultaneously because the variation of concrete work pipe diameter dimension, make seal ring inhomogeneous and easily make seals damaged in the diameter compression.In case seal destroyedly, can cause underground water to flow in the construction pipeline, simultaneously can make push pipe form roadbed subsidence along the line, if also may cause and can't construct close to from building.
Summary of the invention
The object of the invention is to overcome the deficiency that exists in the above-mentioned technology, provide a kind of simple in structure, fabricating cost is low, good seal performance, quick and easy for installation, simple to operate, intensity is high and need not change the flexible joint steel structure relay well device of pipe die.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of flexible joint steel structure relay well device, comprise steel bellmouth, outer sleeve, jack, seal ring, socket ring and socket, outer sleeve and the coaxial setting of socket, the socket ring is fixedly installed with socket is coaxial, outer sleeve inward flange radial equipartition between socket and steel bellmouth is equipped with jack, between the front-end face of this jack and the steel bellmouth front cushion pad is installed, rear cushion pad is installed between the ear end face of jack and the socket; The front outer of socket ring is shaped with the sealed groove that matches with the socket of concrete plug, it is characterized in that: be welded with the hoop gusset in the described socket ring.
And described steel bellmouth is shaped with the reinforcement gusset, and this reinforcement gusset comprises radial reinforced rib plate and cross reinforcing plate.
Advantage of the present invention and beneficial effect are:
1, this device is installed in certain position of a jacking pipe, jacking pipeline of this section is divided into several to be advanced interval, in jack-in process, after first by the priority program pipe being advanced a bit of distance by several relay wells, push away last interval tubing by main top oil cylinder again, design science is reasonable.
2, that one push pipe is divided into several push pipes is interval for this device, and overall structure is simple, good manufacturability, good sealing effect, can be under the complex geological conditions condition as high hydraulic pressure, underground water or earthing reach perfectly safe when dark especially.
3, this device has improved original seal arrangement, can disposablely in the workshop, carry out machining, and miscellaneous part such as socket, steel bellmouth also are to finish by the machining means, not only water level carries out jacking construction on the ground, can also under level of ground water, carry out jacking construction, as the jacking construction such as cross the river of passing by on one's way.
Description of drawings
Fig. 1 is structural front view of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing, by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of flexible joint steel structure relay well device, comprise steel bellmouth 1, outer sleeve 2, jack 4, seal ring 6, socket ring 7 and socket 9, outer sleeve and the coaxial setting of socket, the socket ring is fixedly installed with socket is coaxial, outer sleeve inward flange radial equipartition between socket and steel bellmouth is equipped with jack, front cushion pad 3 is installed between the front-end face of this jack and the steel bellmouth, rear cushion pad 5 is installed between the ear end face of jack and the socket; The front outer of socket ring is shaped with the sealed groove 10 that matches with the socket of concrete plug, and the present embodiment accompanying drawing is twice; Socket ring outer rim in outer sleeve is equipped with seal ring, and the present embodiment accompanying drawing is twice.
Innovative point of the present invention is:
1, is welded with hoop gusset 8 in the described socket ring, strengthened thus the intensity of socket ring, realize that steel bellmouth and seal ring place intensity are larger, can not produce distortion when jacking construction.
2, described steel bellmouth is shaped with and strengthens gusset 11, and this reinforcement gusset comprises radial reinforced rib plate and cross reinforcing plate, makes thus the huge top power that can bear jack and promote mainly oil cylinder, the distortion that can't produce socket.
