Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The hammering type waterproof conduit puncture shoe comprises end teeth 1, a steel tube section 2, outer reinforcing ribs 3 and inner reinforcing ribs 4, wherein a waterproof conduit is welded at one end of the steel tube section 2, tooth grooves 201 are uniformly formed in the circumference of the end face of the other end of the steel tube section 2, the end teeth 1 are welded in the tooth grooves 201, the part of the end teeth 1 welded in the tooth grooves 201 is of a rectangular structure, and the part of the end teeth 1 far away from the tooth grooves 201 is of a long bullet head structure; the outer wall circumference of the steel pipe shell ring 2 is uniformly welded with outer strengthening ribs 3, the outer strengthening ribs 3 are perpendicular to the steel pipe shell ring 2 in the radial direction, and the end parts of the outer strengthening ribs 3 are provided with chamfers, wherein the chamfers are 60 degrees; 2 inner walls of steel pipe shell ring evenly be equipped with interior strengthening rib 4, interior strengthening rib 4 divide into one section diagonal rib and two sections straight muscle, the diagonal rib radian laminate with 2 inner walls of steel pipe shell ring mutually, the diagonal rib both ends connect straight muscle, two sections straight muscle distribute on the circumference and differ 30, straight muscle tip be equipped with the chamfer, and the chamfer is 60.
The end teeth 1 are made of tungsten steel.
The number of the end teeth 1 is 24-48.
The number of the tooth grooves 201 is 24-48.
The steel tube shell ring 2 is a steel grade straight seam tube or a seamless tube.
The outer reinforcing ribs 3 are 12-24.
The inner reinforcing ribs 4 are 4-6.
The formula water proof pipe puncture shoes are hammered into to, and the steel pipe shell ring 2 inside and outside wall welding direction strengthening rib improves puncture shoes vertical and horizontal intensity and hammering direction. The front end of the puncture shoe is inlaid with the end teeth 1, so that the penetration degree of the hammering type water-resisting guide pipe is improved, the contact area of the end teeth 1 and rock soil is small, the hardness is high, and the puncture shoe has a better layer breaking effect when penetrating through a hard stratum and a gravel layer.
