Description

Grouting pipe

Technical Field

The utility model relates to a construction technical field, in particular to slip casting pipe.

Background

In the building construction process, when reinforcing some sections or soft soil layers which are easy to collapse, grouting pipes are generally adopted to infuse grout into the corresponding sections or soil layers for reinforcement. During construction, a hole is drilled at a designated grouting position, and then a grouting pipe is inserted into the hole to perform grouting operation. When the lengths of the grouting pipes are insufficient, the grouting pipes are often connected with one another to increase the lengths, the existing grouting pipes are usually connected with one another by threads, and the grouting pipes can slip after being used for a long time; in addition, the grouting pipe or the pipe joint needs to be rotated in the process of threaded connection, the installation is more complicated, and particularly for longer cast-in-place piles, the installation speed is low, and the construction efficiency is influenced.

Furthermore, the utility model discloses still provide following subsidiary technical scheme: the inner diameter of the sleeve is larger than the diameter of the base.

The second wedge block comprises a contact surface abutted to the inner wall of the sleeve, and the contact surface is an arc-shaped contact surface.

The second connecting pipe also comprises a connecting pipe body integrally connected with the sleeve, and the connecting pipe body is communicated with the sleeve.

The connecting pipe body is internally provided with an accommodating cavity for accommodating the first connecting pipe.

The accommodating cavity is provided with an abutting part, and the end face of the first connecting pipe is abutted against the abutting part.

And a sealing ring is arranged between the end face and the abutting part.

Compared with the prior art, the utility model has the advantages of: the utility model discloses the first connecting pipe of slip casting pipe is equipped with the wedge that can outwards expand, and the second connecting pipe be equipped with the sleeve of wedge butt, need not to set up extra screwed pipe joint, and the installation rate is fast, and can not cause smooth silk phenomenon in the connection.

Detailed Description

The following non-limiting detailed description of the present invention is provided in connection with the preferred embodiments and accompanying drawings.

As shown in fig. 1, the present embodiment provides a grout pipe comprising a first connecting pipe 1 and a second connecting pipe 2 detachably connected.

With further reference to fig. 2, the first connecting tube 1 comprises a wedge set, an adjusting nut 4 and a base 5. The wedge block group includes first wedge 3 and second wedge 6, and first wedge 3 is connected in the outer wall of first connecting pipe 1, and recess 11 has been seted up to 1 outer wall of first connecting pipe, and first wedge 3 inlays to be established in recess 11 to fix through the screw. The base 5 is a circular base, the movable sleeve is arranged on the first connecting pipe 1, the second wedge block 6 is arranged on the base 5, the second wedge block 6 is matched with the first wedge block 3 in an inclined plane, and the second wedge block 6 is partially embedded in the groove 11 and used for positioning the second wedge block 6. The adjusting nut 4 is arranged below the base 5 and is in threaded connection with the first connecting pipe 1. Preferably, the wedge-block sets of this embodiment are three pairs and are evenly distributed along the circumference of the base 5.

With further reference to fig. 2 to 5, the second connecting pipe 2 includes a sleeve 7 and a connecting pipe body 8 integrally formed with the sleeve 7, the sleeve 7 is configured to be sleeved on the first connecting pipe 1, and an inner wall of the sleeve 7 abuts against the second wedge block 6. Preferably, the inner diameter of the sleeve 7 is larger than the diameter of the base 5, so that the base 5 can enter the sleeve 7 under the driving of the adjusting nut 4. Through rotatory adjusting nut 4, adjusting nut 4 upwards removes to drive base 5 rebound, second wedge 6 outwards expands along the inclined plane, makes its contact surface 61 and the inner wall looks butt of sleeve 7, thereby realizes that first connecting pipe 1 and second connecting pipe 2 are fixed. Preferably, the contact surface 61 is an arc-shaped contact surface, so that a larger contact area with the sleeve 7 is ensured, friction is increased, and the connection is firmer. Connecting pipe body 8 is linked together with sleeve 7, is equipped with the chamber 9 of acceping that holds first connecting pipe 1 in the connecting pipe body 8, and during the installation, first connecting pipe 1 wears to establish in acceping chamber 9 to communicate with each other with connecting pipe body 8. Specifically, the housing chamber 9 is provided with an abutting portion 91, and the end surface 12 of the first connecting pipe 1 abuts against the abutting portion 91. Preferably, a seal ring 10 is provided between the end face 12 and the contact portion 91, so that leakage of slurry can be prevented.

The utility model discloses when the slip casting pipe used, only need to establish sleeve 7 cover on first connecting pipe 1, make connecting pipe body 8's butt portion 91 and terminal surface 12 looks butt, rotatory adjusting nut 4 again makes second wedge 6 outwards expand and with sleeve 7's inner wall looks butt, can realize the connection of first connecting pipe 1 and second connecting pipe 2. The first connecting pipe 1 is inserted into the accommodating cavity 9 of the second connecting pipe 2, the end face 12 of the first connecting pipe 1 abuts against the abutting part 91 of the accommodating cavity 9, and the sealing ring 10 is arranged between the accommodating cavity 9 and the end face 12, so that the leakage of the pipe wall can be effectively avoided.

The beneficial effects of the utility model are that, the utility model discloses the first connecting pipe of slip casting pipe is equipped with the wedge that can outwards expand, and the second connecting pipe is equipped with the sleeve with the wedge butt, need not to set up extra screwed pipe joint, and the installation rate is fast, and can not cause smooth silk phenomenon in the connection.
