Abstract
The utility model discloses an underground injection pipe, and belongs to injection pipes. The injection pipe is connected by a plurality of sections of injection pipes, wherein the two adjacent injection pipes are connected through a fast pipe joint connecting structure, the fast pipe joint connecting structure has the structure that the outer walls on two ends of each section of the injection pipe are respectively welded with a positioning ring, the joint of two injection pipes is sleeved in a sealing ring, a fast pipe joint is used for fixing the outside of the joint of two injection pipes, a groove is arranged on the pipe joint corresponding to the positioning ring, the positioning ring is clamped in the groove, the fast pipe joint consists of two semicircular joints whose inner diameter is matched with the outer diameter of the injection pipe, and the two ends of the fast pipe joint are fastened by high-strength bolts and nuts. The underground injection pipe has the advantages that the injection pipe and the pipe joint do not need welding to connect, the hidden danger of weld line leakage is avoided, the detachment is convenient, the service life is long, and the strength of field maintenance and replacement by workers is reduced.
Description
Technical field
The utility model relates to a kind of Grouting Pipe, specifically is a kind of down-hole Grouting Pipe.The grouting pipeline that is fit to slurry conveyed in the mortar depositing construction of down-hole uses.
Background technology
At present, the grouting pipeline that down-hole mortar depositing construction engineering is used does not still have standard, and pipeline fast joint directly welds at the Grouting Pipe two ends in each mortar depositing construction unit now, utilizes U type card that two Grouting Pipe joints are connected.The major defect that this scheme exists is:
1. between Grouting Pipe and pipe joint welding line is directly contacted slurries, bear liquid high pressure.Because on-the-spot no weld seam inspection machine only with perusal, can not accomplish to weld zero-fault.The grouting pipeline of postwelding very easily seeps water when carrying slurries under pressure, water leakage fault, and then causes the spillage accident, influences construction safety and job scheduling.
2. pipeline fast joint is for being rigidly connected, and axially and all flexible surplus of angle direction, and joint is an embedded structure between two Grouting Pipe, must guarantee end play greater than embedding apart from the time just can take apart.Because the restriction of structure makes grouting pipeline to take apart arbitrary joint in the centre, this changes to field maintenance and brings very big inconvenience.As long as when having a Grouting Pipe generation seepage to change in the construction, must from whole grouting pipeline system begin foremost tear the Grouting Pipe that need are changed open always, could change, waste time and energy, influence work efficiency.
Summary of the invention
In order to overcome the deficiency of existing down-hole grouting pipeline welding seam leakage, repair and replacement difficulty, the utility model provides a kind of down-hole Grouting Pipe, and this down-hole Grouting Pipe has not only fundamentally been stopped the problem of welding seam leakage, and on-the-spot replacing is easy, time saving and energy saving; And keep certain axial telescopic gap and deflection angle between Grouting Pipe, allow Grouting Pipe that certain angular deviation, dislocation are relatively arranged.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of down-hole Grouting Pipe, connect to form by some joint Grouting Pipe, it is characterized in that adopting the quick coupling syndeton between adjacent two joint Grouting Pipe, described quick coupling syndeton is: be welded with a locating ring on the outer tube wall of the two ends of every joint Grouting Pipe, the joint of two joint Grouting Pipe is enclosed within the sealing ring, the outside is fixedly connected with quick coupling, the position corresponding to locating ring of union is provided with groove, locating ring is stuck in the groove, described quick coupling is made up of the semicircle joint that two internal diameters cooperate with the Grouting Pipe external diameter, and its two ends are fastenedly connected with the high-strength bolt nut.
Owing to adopted technique scheme, making adjacent two Grouting Pipe axially be not direct contact, but by the high pressure rubber ring set in the middle of two Grouting Pipe, the physical dimension of union, Grouting Pipe and sealing ring guaranteed two Grouting Pipe can be in effective seal distance of sealing ring axial telescopic gap and free deflection angle, allow Grouting Pipe that certain angular deviation, dislocation are relatively arranged.Gapped expansion, the contraction that adapts to pipeline between the two Grouting Pipe pipe ends, and easy disassembly.
The beneficial effects of the utility model are: owing to the welding of employing between Grouting Pipe and the union, thereby fundamentally stopped the hidden danger of welding seam leakage; And the existence at axial telescopic gap between two Grouting Pipe and free deflection angle can be taken the Grouting Pipe of arbitrary position at an easy rate at the scene apart, need not from order completely knocked down foremost.The functional reliability that this has improved Grouting Pipe has greatly prolonged its application life, has reduced the intensity that workman's field maintenance is changed simultaneously, has improved operating efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1. Grouting Pipe, 2. locating ring, 3. sealing ring, 4. union, 5. high-strength bolt, 6. packing ring, 7. high-strength nut.
The specific embodiment
As depicted in figs. 1 and 2, the two ends of sealing ring 3 are set with 1 of 1, two Grouting Pipe of two Grouting Pipe and leave the gap.Locating ring 2 is welded on the outer wall of Grouting Pipe 1, and quick coupling 4 is made up of the semicircle joint that two internal diameters cooperate with the Grouting Pipe external diameter, and its two ends are connected and fixed with high-strength bolt 5, packing ring 6, high-strength nut 7.Union 4 utilizes locating ring 2 axial location, and the grouting pipeline after the assembling utilizes the existence of the elasticity and the end play of sealing ring, can allow Grouting Pipe that certain angular deviation, dislocation are relatively arranged, and can adapt to expansion, the contraction of pipeline simultaneously, and easy disassembly.Can be in effective seal distance of sealing ring between two Grouting Pipe axial telescopic gap 4～20mm, 0 °～3 ° at free deflection angle.
Claims (2)
1. down-hole Grouting Pipe, connect to form by some joint Grouting Pipe (1), it is characterized in that adopting the quick coupling syndeton between adjacent two joint Grouting Pipe, described quick coupling syndeton is: be welded with a locating ring (2) on the outer tube wall of the two ends of every joint Grouting Pipe, the joint of two joint Grouting Pipe is enclosed within the sealing ring (4), the outside is fixedly connected with quick coupling (4), the position corresponding to locating ring (2) of union (4) is provided with groove, locating ring (2) is stuck in the groove, described quick coupling (4) is made up of the semicircle joint that two internal diameters cooperate with the Grouting Pipe external diameter, and its two ends are fastenedly connected with the high-strength bolt nut.
2. down-hole according to claim 1 Grouting Pipe is characterized in that leaving the gap between two joint Grouting Pipe.
