Abstract
The utility model discloses a pipe-jacking construction guide pipe provided with a deviation rectification wing board, belongs to the technical field of rectification of outdoor pipeline installation engineering pipe-jacking construction, and aims to overcome the defects that a simple and effective method is not provided for complex rectification operation and pipe-jacking rectification of small pipe diameters during pipe-jacking construction processes at present. The pipe-jacking construction guide pipe comprises a guide pipe provided with the rectification wind board, the right end of the rectification wing board, close to the guide pipe edge, is hinged with the guide pipe, and the left end of the rectification wing board is provided with a jacking mechanism. The pipe-jacking construction guide pipe is suitable for pipe-jacking construction work.
Description
Technical field
The utility model relates to a kind of deviation correcting technology of yard piping installing engineering jacking construction, particularly relates to a kind of jacking construction elder generation conduit that the correction wing plate is housed.
Background technique
Laying of yard piping, the general method that adopts the fluting pipe laying, but, when pipe top earthing is dark, the fluting earth volume is too large, perhaps traversing pipe line railway, highway, river, urban road and various building, fluting is had any problem, and when the busy section of town construction can not be stopped traffic, all will adopt the Pressure pipe method of construction.Pipeline is in jack-in process, because the frontal resistance that the nonuniformity of misoperation and soil property causes is irregular, the uneven and jack top power of frictional force small eccentric waits and all may cause first conduit direction of advance to be offset or rotate around the tube wall.In order to guarantee the construction quality of pipeline, must in time to correct, just can avoid deviation excessive.Experience according to long-term jacking construction, people have summed up the method for several corrections, as the correction method of cutting the earth, jack rafter correction method, little jack method, add pading plate correction method etc., the method for correcting error that these are different, although effectively, all need to have the special messenger to go operation, and corresponding operating space will be arranged, in a word, complicated during operation; Especially can't when the less jacking construction of caliber, adopt.The less correction of pipeline in the jacking construction process proofreaied and correct for caliber at present, also do not have comparatively simple and easy effective method.Usually can only adopt the method for cushioning wedge between push pipe terminal and top iron, make to form an angle between push pipe and the top iron, make push pipe when jacking, get back to gradually the tram,, this correction method formerly conduit from initial position close to the time more effective, in case jacking was just often lost efficacy after dark.
Summary of the invention
The purpose of this utility model provides a kind of jacking construction elder generation conduit that the correction wing plate is housed, and overcomes at present in the jacking construction process, and the correction operation is complicated, for the deficiency that also is provided with a kind of simple and easy effective ways than the top pipe deviation correcting of pipe with small pipe diameter.
The utility model is achieved by following technical proposals.
The utility model comprises first conduit, is provided with the correction wing plate, the right-hand member of described correction wing plate, namely near an end of described first conduit cutting edge be connected first conduit strand and connect, be provided with at the left end of described correction wing plate and back down mechanism.Pipe during jacking, can run into the resistance of two aspects forward: the one, and the frictional force of pipeline outer wall and soil, the 2nd, the crush resistance of first conduit front end soil compaction.Because guide's pipe has cutting edge, its crush resistance is significantly smaller than the frictional force of pipeline outer wall and soil.In the utility model, utilize just the method for backing down described correction wing plate, the frictional force of the radially some directions of described first conduit outer wall and soil is increased, thereby the direction of advance of described first conduit is changed.
In the utility model, the mechanism that backs down to described correction wing plate preferably adopts gusset formula or wedgeplate-type, and the former is equipped with seat board on the described first conduit on described correction wing plate both sides, and gusset is housed between described seat board rotationally; Described first conduit is equipped with bearing on the described seat board left side, at described bearing nut and screw rod is housed, and by pull bar described gusset is connected with screw rod.The latter is equipped with door shape frame on the described first conduit on described correction wing plate both sides, between described door shape frame wedge is housed; Described first conduit is equipped with bearing on the described door shape frame left side, at described bearing nut and screw rod is housed, and by pull bar described wedge is connected with screw rod.When implementing, as long as the described screw rod of rotation makes described gusset rotation or wedge move left and right by described pull bar, described correction wing plate is backed down or returning position.
More accurate on direction for the correction power that described first conduit is subject to, should along the circumference of described first conduit, be provided with in uniform way six described correction wing plates.Simultaneously, for the less first conduit of caliber, be convenient to carry out at the push pipe terminal remote positive and negative rotation operation of described screw rod, the left end of described screw rod is connected with extension rod.
Against existing technologies, the beneficial effects of the utility model are:
Can make the correction operation in the jacking construction easier, especially to the top pipe deviation correcting operation than small-caliber pipeline, can carry out telecontrol, definite effect.
Description of drawings
Fig. 1 is the structural representation that mechanism is the embodiment of gusset formula that backs down described in the utility model, Fig. 2 be the A of Fig. 1 to diagram, Fig. 3 is the structural representation that mechanism is the embodiment of wedgeplate-type that backs down described in the utility model.Among the figure: 1, first conduit, 2, the correction wing plate, 3, seat board, 4, gusset, 5, bearing, 6, nut, 7, screw rod, 8, pull bar, 9, door shape frame, 10, wedge, 11, extension rod.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Because in the jacking construction, various parts all will be subject to great active force and reaction force, and all be in extremely abominable underground environment work, so each parts in the utility model, part must have enough rigidity, to correction wing plate 2 Ying Zaiqi inwardly one side establish stiffening rib.In the jacking construction process, when occurring to carry out first conduit 1 correction timing, radially seeing of before conduit 1, handle the extension rod 11 to an anti-side of deflection direction, screw rod 7 is screwed out from nut 6, gusset 4 is forward rotated or wedge 10 is moved to the left by pull bar 8, correction wing plate 2 is backed down.The correction wing plate 2 that backs down plays two effects, the one, increased and soil between frictional force, the 2nd, the afterbody of first conduit 1 is applied moment, make first conduit produce corner, thereby change the direction that first conduit 1 advances, reach the purpose of correction.Sometimes also can close several correction wing plates 2 simultaneously in various degree back down the operation of rectifying a deviation.After the correction operation was finished, as long as screw rod 7 precessions are gone, then gusset 4 backward rotation or wedge 10 withdrawed from, and under the pressure of soil, correction wing plate 2 can automatically reset.
