Abstract
The utility model discloses a grooved perforated small duct for grouting, and aims to solve the technical problems of low overall rigidity, complex manufacturing process and high time consumption of the conventional small duct. The grooved perforated small duct for grouting comprises a grouting tube body (1), grooved grouting holes (2) and a tapered tube tip (3), and is characterized in that the grooved grouting holes (2) are arranged in the grouting tube body (1); the openings of the grooved grouting holes (2) are grooved in the longitudinal direction; the grooved grouting holes (2) are arranged in the surface of the grouting tube body (1) in a plum flower form; and the tapered tube tip (3) is arranged at the tail part of the grouting tube body (1). Due to the adoption of the grooved perforated small duct for grouting, the manufacturing process is simple, less time is consumed, the overall rigidity of a steel tube for grouting is reduced slightly, and the slurry discharge amount per unit time shows little change, so that the advanced support capability of the small duct for grouting is effectively enhanced.
Description
One, technical field
The utility model relates to a kind of slot-like opening slip casting ductule in the tunnel civil engineering, is the improvement to existing slip casting ductule.
Two, background technology
In constructing tunnel, often adopt advanced tubule that weak, broken, loose country rock are carried out advance support and grouting and reinforcing, the supporting capacity that is used for guaranteeing the safety of digging process and strengthens preliminary bracing.The advanced tubule grouting support mainly is to apply ductule along arch, tunnel periphery hoop, by the plum blossom-shaped injected hole on the ductule slurries is diffused to loose rock mass, utilizes the slurry consolidation rock mass, forms stable fixed donor together with ductule.Grouting Pipe has two effects: the one, and the effect of Shed-pipe Advanced Support; The 2nd, the effect of grouting and reinforcing.
The normal mode that adopts of traditional slip casting ductule is: bore the approximately circular hole of 1～2cm on steel pipe (being ductule) surface, about spacing of wells 15cm, injected hole is plum blossom-shaped and arranges.Because the diameter of steel tube itself that slip casting ductule adopts is less, the lengthwise of steel pipe and the ratio of diameter are very large, this mode at the intensive layout injected hole of steel tube surface, although considered slip casting effect, but causing the reduction of the integral rigidity of ductule, obviously is disadvantageous for its function of strengthening adjoining rock stability of performance.
Three, summary of the invention
The utility model purpose provides a kind of novel slot-like opening slip casting ductule, is used for solving traditional ductule integral rigidity low, the technical problem that complex manufacturing technology and spended time are more.
The technical scheme that realizes the utility model and adopt is:
A kind of slot-like opening slip casting ductule, comprise slip casting body, flute profile injected hole, taper tip, it is characterized in that: at the slip casting body flute profile injected hole is set, flute profile injected hole opening be shaped as longitudinally flute profile, the flute profile injected hole is plum blossom-shaped to be arranged in the Grouting Pipe surface, at slip casting body afterbody the taper tip is set.
The length of described flute profile injected hole and width ratio were greater than 15: 1.
The spacing of described flute profile injected hole between vertically is greater than 3 times flute profile injected hole opening length.
Apply the advantage that method is compared and had with existing: adopt this novel flute profile slip casting ductule, manufacture craft is simple, the time less of cost, integral rigidity for the grouting steel pipe reduces less, and the slurry-outlet quantity of unit interval changes little, thereby has effectively strengthened the advance support ability of slip casting ductule.
Four, description of drawings
The structural representation of this device of Fig. 1
Five, the specific embodiment
Referring to Fig. 1, the utility model is a kind of slot-like opening slip casting ductule, it comprises slip casting body (1), flute profile injected hole (2), taper tip (3), it is characterized in that: at slip casting body (1) flute profile injected hole (2) is set, flute profile injected hole (2) opening be shaped as longitudinally flute profile, flute profile injected hole (2) is plum blossom-shaped to be arranged on slip casting body (1) surface, at slip casting body (1) afterbody taper tip (3) is set.
The length of described flute profile injected hole and width ratio were greater than 15: 1.
The spacing of described flute profile injected hole between vertically is greater than 3 times flute profile injected hole opening length.
The slip casting body is formed by the steel pipe cutting processing, and the steel pipe afterbody is pounded pointed tapered tip after cutting into the slit, and the flute profile injected hole can form not perforate in distance steel pipe tail end 100cm by the cutting machine cutting.By the perforate mode of flute profile, the percent opening of steel tube surface reduces, and integral rigidity increases than traditional approach.
Claims (3)
1. slot-like opening slip casting ductule, it comprises slip casting body (1), flute profile injected hole (2), taper tip (3), it is characterized in that: at slip casting body (1) flute profile injected hole (2) is set, flute profile injected hole (2) opening be shaped as longitudinally flute profile, flute profile injected hole (2) is plum blossom-shaped to be arranged on slip casting body (1) surface, at slip casting body (1) afterbody taper tip (3) is set.
2. described slot-like opening slip casting ductule according to claim 1 is characterized in that, the length of described flute profile injected hole (2) and width ratio were greater than 15: 1.
