Abstract

The utility model relates to a mortar-intrusion pipe which comprises a pipe body and pipe joints, wherein the pipe body is provided with a pipe cavity and the pipe joints are arranged at the end part of the pipe body. Flanges which outwards extend along the radical direction of the pipe body are fixedly arranged on the pipe body, and raised convex ribs are arranged on the end surface of the flanges. Resistance force between the mortar-intrusion pipe and concrete in an axial direction is increased by the flanges, and the mortar-intrusion pipe does not easily generate axial displacement relatively to the concrete; thereby, the firmness of a concrete frame can be reinforced.

Description

Madjack pipe

Technical field

The utility model relates to a kind of constructing tunnel that is used for, and passes the madjack pipe of concrete slab.

Background technology

In the prior art, the madjack pipe that is used for the concrete slab of constructing tunnel generally includes body, and this madjack pipe passes concrete pipe and is embedded in the concrete, is used to pass bolt, lead etc. in the body.But because the body integral body of this madjack pipe is continuous cylindrical, thus its in concrete easily because vibrations etc. are former thereby relative concrete generation axial displacement, thereby easily accidents caused.

Summary of the invention

The utility model purpose provides a kind of madjack pipe, and its concrete relatively position in concrete slab firmly is difficult for moving axially.

For achieving the above object, the technical solution adopted in the utility model is: a kind of madjack pipe, comprise body with tube chamber, and be set with the flange that extends radially outwardly on the described body along body.

The end of described body is provided with union.

Lobed convex tendon on the end face of described flange.

Described convex tendon is the circular concentric with the flange concentric.

Have many convex tendons respectively on the both sides end face of described flange.

Because technique scheme utilization, the utility model compared with prior art has following advantage: fixedly install flange on body, flange makes the relative concrete of this madjack pipe increase at axial resistance, so the relative concrete of madjack pipe is difficult for producing axial displacement, thereby can strengthen the steadiness of concrete frame.

Description of drawings

Accompanying drawing 1 is a stereogram of the present utility model;

Accompanying drawing 2 is a front view of the present utility model;

Accompanying drawing 3 is a main sectional view of the present utility model;

Wherein: wherein: 1, body; 2, flange; 3, convex tendon; 4, tube chamber; 5, union;

The specific embodiment

Referring to accompanying drawing 1-accompanying drawing 3, a kind of madjack pipe, the union 5 of the end that comprise body 1 with tube chamber 4, is arranged at described body 1 is set with the flange that extends radially outwardly 2 along body 1 on the described body 1.The utility model passes bolt, lead etc. in the tube chamber 4 of its body 1 when practical application.The setting of flange 2 makes that the axial resistance between this madjack pipe and the concrete increases, and can make the relative concrete of madjack pipe firmly be difficult for producing axial displacement

Referring to accompanying drawing 2-accompanying drawing 3, lobed convex tendon 3 on the end face of described flange 2, described convex tendon 3 are the circular concentric with the axial line concentric of flange 2.In the accompanying drawing 2, have many convex tendons 3 respectively on the both sides end face of described flange 2, and the corresponding convex tendon 3 in both sides is the identical circle of radius.In the embodiment shown in Figure 2, have three convex tendons 3 respectively on the both sides end face of described flange 2.The formation of convex tendon 3 has strengthened the rigidity of flange 2, and is not yielding when making it be subjected to the concrete extruding, and increased the radially resistance between madjack pipe and the concrete, further strengthened the steadiness of this madjack pipe in concrete.
