Abstract
The utility model relates to an intermediate jacking station of relay jacking steel pipes. The intermediate jacking station of the relay jacking steel pipes comprises front steel pipes, rear steel pipes, front jacking rings, rear jacking rings, jacks, internal casing pipes and external casing pipes; the external pipes are fixedly installed on interface positions of the front steel pipes; the external casing pipes coaxially extend onto the rear steel pipes; waterproof seal rings are installed between the external casing pipes and the rear steel pipes; the internal casing pipes are fixedly installed on the rear jacking rings which are arranged at rear ends of the jacks; the internal casing pipes coaxially extend into the front steel pipes; and waterproof seal rings are installed between the internal casing pipes and the front steel pipes. The intermediate jacking station of the relay jacking steel pipe has the advantages of being economical and practical, good in sealing performance, high in strength, convenient to install, simple to operate and good in rectification flexibility and being capable of preventing high confined water pouring into the pipelines.
Description
Technical field
The utility model belongs to the municipal engineering field, relates to long distance or over distance steel pipe jacking construction, especially a kind of relay well device of relay jacking steel pipe.
Background technique
Long-distance pipe jacking refers to all jacking constructions more than 300m of distance that each section advance continuously, reached at the 1000m that has or more than the 1000m.Because the one-time continuous advance distance is longer, so just produced many differences with common jacking construction, also just have many factors to the restrictive function of long-distance pipe jacking.And at present to the research of long-distance pipe jacking construction, just study these differences and seek to solve the method for these restraining factors.
Relay well is the relay jacking working room that arranges in the middle of the jacking pipeline section, the inner relaying jack of installing in this working room, pipeline section jacking before undertaking between interruption, after interrupting jack propelling front pipeline section, promote mainly the pipeline section that jack advances back between interruption again, if distance is long, just can lay a plurality of relay wells, the method of this segmentation relay jacking is called jacking between the relay interruption.In municipal engineering at present, public waterworks, mid-water engineering jacking construction, adopt above method construction mostly.Not prosperous even do not have under the phreatic situation at underground water, the jacking steel pipe steel pipe relay well method that adopts is fairly simple mostly, specifically adopts methods two-layer, two envelopes comparatively general; Under the situation of even high artesian more prosperous at underground water, adopt multiple-sealed form to solve more.Because seal ring adopts rubber to make mostly, and when relaying is worked, because when the jacking steel pipe, the relay well outer sleeve is working in reciprocating mode, and outer sleeve is generally without machining, and internal surface is more coarse, so the wearing and tearing of rubber ring are comparatively serious, the maximum difference of steel pipe jacking construction and concrete pipe jacking construction is that all interfaces of steel pipe all weld, and it is flexible that the interface of concrete pipe then shows.Brought the pros and cons of steel pipe push pipe thus, favourable one side is if just grasp the direction of jacking in initial jacking, then can jacking afterwards in, steel pipe generally not conference produces bigger deviation, makes the push pipe jacking very well; Disadvantageous one side is if the jacking direction is grasped badly, just is not easy to correct to come.If that corrects is too quickly, problems such as push pipe distortion, weld bond disengagement also can occurs, even the disastrous effect that push pipe is scrapped can occur.
The model utility content
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provide a kind of economical and practical, good seal performance, easy for installation, simple to operate, correction flexible good, can prevent that high artesian from pouring into the relay well device of the higher relay jacking steel pipe of pipeline and intensity.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of relay well device of relay jacking steel pipe, comprise preceding steel pipe, back steel pipe, preceding apical ring, back apical ring, jack and inner sleeve, outer sleeve, preceding steel pipe is coaxial with the footpath setting with the back steel pipe, coaxially in preceding steel pipe install preceding apical ring, the coaxial back apical ring that installs in the steel pipe of back, the outer rim position installs jack between preceding apical ring and back apical ring, preceding steel pipe with the back steel pipe the interface position respectively coaxial package outer sleeve and inner sleeve are arranged, it is characterized in that: the interface position of steel pipe before described outer sleeve is packed in, outer sleeve is coaxial to be extended on the steel pipe of back, between outer sleeve and back steel pipe waterproof grommet is installed; Described inner sleeve is coaxial to be packed on the back apical ring of jack outer end, inner sleeve is coaxial extends to before in the steel pipe, between inner sleeve and preceding steel pipe, waterproof grommet is installed.
And, be coaxially installed with cushion pad respectively between described jack and preceding apical ring, the back apical ring.
And, be fixed with the triangle muscle respectively between described preceding apical ring, back apical ring and preceding steel pipe, the back steel pipe.
Advantage of the present utility model and beneficial effect are:
1, this relay well device all is provided with triangle muscle and apical ring before and after jack, make jack all power when work act on front and back apical ring and triangle muscle place fully, the thrust of bearing is about the twice of jack top power summation, has effectively strengthened the intensity of this device.
2, this relay well device is provided with cushion pad at jack and forward and backward apical ring contact position, when making the jacking steel pipe, the thrust of relay well jack acts directly on the apical ring, has avoided pressure to concentrate and the relay well apical ring sideslip problem that causes; Cushion pad is generally made by sandwich plate, also can make with rubber plate, can play the effect of even transmission top power.
3, this relay well device welds an outer sleeve at preceding steel pipe, and when the jack jacking, outer sleeve is mobile with preceding steel pipe, and twice water proof rubber circle is set in the outer sleeve, prevents that underground water from entering in the interior cover; Simultaneously inner sleeve be with the apical ring coaxial welding together, between inner sleeve and the preceding steel pipe twice waterproof grommet is set, can prevent the seepy question that causes after the seal ring damage of outer sleeve, strengthened the water-proof function of whole device.In addition, the setting of waterproof grommet also can effectively be implemented in and cross the river jacking and good sealing effect is arranged during the artesian water jacking construction under the highland.
