Description
Technical field
The utility model relates to the quick connection push pipe tube coupling device that a kind of concrete tube coupling that is applied to underground pipe-jacking project connects, and belongs to tube coupling connection set field.
Background technique
Push pipe tube coupling commonly used at present adopts the socket joint mode, is commonly called as " F pipe ", and this interface mode is a flexible interface, has occurred many problems in a large amount of using processs, and the one, the tube coupling drift can't be rectified a deviation when running into hag matter; The 2nd, in the push pipe jack-in process during backhaul of rear jack, tube coupling is prone to throw off etc. under the earth pressure effect; The 3rd, when surrounding soil ran off, opening sank easily.
For addressing these problems existing treatment measures in the practice of construction:
1, the pre-buried iron plate of push pipe precast plant, job site welding stiff skeleton connects;
2, push pipe precast plant does not have pre-buried iron plate, and job site welding stiff skeleton connects, and wherein tube coupling adopts bolt to be connected with stiff skeleton, and bolt adopts boring to bury underground.
More than the shortcoming of two kinds of methods be consuming timely longly influence work efficiency, bring potential safety hazard, and interim connect remove difficult.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, and a kind of all functions of existing tube coupling that both possessed are provided, the quick connection push pipe tube coupling device that can in needs, tube coupling carried out fast, effectively connect easily again.
The purpose of the utility model is accomplished through following technological scheme, and it comprises two continuous push pipe tube couplings, be provided with the arc pre-manufactured hole separately on described two push pipe tube coupling inwalls, and this arc pre-manufactured hole is symmetrical distribution; Described two push pipe tube couplings are provided with rubber seal outside these two push pipe tube couplings that are fixed together through the arc bolt together.
As preferably, the two ends of described arc bolt are provided with screw thread, and the two ends of this arc bolt are inserted in the arc pre-manufactured hole that is symmetrical distribution, and are tightened fixing by nut.
As preferably, the port of described push pipe tube coupling is 90 °, is provided with the depression Processing Structure around the inboard tail end of push pipe tube coupling tube wall.
The beneficial effect of the utility model is: can be fast, convenient and safe when requirement of engineering, effectively the push pipe tube coupling is realized connecting lock function through special arc bolt, mainly be presented as 3 points:
1, on the safety, novel push pipe tube coupling Placement is because of having avoided using electric welding, gas cutting in abominable, complicated, the confined space environment in the push pipe tube coupling of down-hole; And then avoid because the toxic flue dust gas of electric welding, gas cutting generation is managed the atmospheric pollution in the interior confined space to the down-hole; Avoid taking place the incident and the dead incident of getting an electric shock because the poisoning that electric welding, gas cutting factor bring is suffocated;
2, on the structure, novel push pipe tube coupling Placement is simple in structure, does not change push pipe tube coupling function of use, not only satisfies structure stress requirement and usage requirement in all constructions and the using process, also helps the working life of improving pipeline;
3, on the efficient, novel push pipe tube coupling connects means of fixation and adopts the connection of arc bolt fixing, connects in the pipe to need not heavy supplementary equipment; Only use artificial with the arc bolt; Install and insert tube coupling arc pre-manufactured hole, use torque wrench to tighten nut then and get final product, reduced operator's operation intensity and installation time greatly; And then shortened push pipe because of connect inevitably break period temporarily, improved push pipe operation effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Label in the accompanying drawing is respectively: 1, push pipe tube coupling, 2, the arc pre-manufactured hole, 3, the arc bolt, 4, rubber seal, 5, nut.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1; The utility model comprises two continuous push pipe tube couplings; It is characterized in that: be provided with arc pre-manufactured hole 2 separately on described two push pipe tube coupling 1 inwalls, and this arc pre-manufactured hole 2 is symmetrical distribution; Described two push pipe tube couplings 1 are fixed together through arc bolt 3, and these two push pipe tube coupling 1 outsides that are fixed together are provided with rubber seal 4.
The two ends of described arc bolt 3 are provided with screw thread, and the two ends of this arc bolt 3 are inserted in the arc pre-manufactured hole 2 that is symmetrical distribution, and tighten fixing by nut 5.The port of described push pipe tube coupling 1 is 90 °, is provided with the depression Processing Structure around the inboard tail end of push pipe tube coupling 1 tube wall.
The utility model is for realizing that the push pipe tube coupling is quick through the arc bolt, effectively connecting; On the prefabricated tube coupling of existing push pipe basis; Carrying out local structure improves; The tube coupling port is 90 °, is symmetrical set push pipe tube coupling 1, does depression around the inboard tail end of push pipe tube coupling 1 tube wall and handles (realizing through prefabricated press mold).Should guarantee pre-buried push pipe tube coupling 1 location in the prefabricated process accurately, and before dispatching from the factory, at push pipe tube coupling 1 outer wall delineation push pipe tube coupling control axis.
Novel push pipe tube coupling arc bolt attended operation step and requiring as follows:
1, checks whether the novel push pipe tube coupling 1 that dispatches from the factory is provided with correct, whether delineates pipe outer wall tube coupling control axis, and the sizing deviation should be greater than 2mm;
2, the push pipe tube coupling lifts by crane, transfers in the engineering and should align so that adjust tube coupling according to the control axis all the time with the control axis up, and deviation must not be greater than 1mm;
3, narrow and small because of space in the push pipe tube coupling 1, be not easy to many people's operations, adopt arc bolt 3 to connect, highlight advantage, single following operation: arc bolt 3 is inserted in the push pipe tube coupling 1 according to arcuate directions; If any inserting difficulty a little, then use hammer to knock arc bolt 3, make it to pass smoothly arc pre-manufactured hole 2; Use torque wrench that nut is tightened.
4, the arc bolt connects the fixing symmetry of answering.
Except that the foregoing description, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
