Abstract

The grouting pipe tee joint is mainly used for post grouting in building construction and comprises a transverse pipe, a vertical pipe, screw threads, a hose and binding wires; drilling a connecting hole with the diameter of 2cm in the middle of a 13cm long transverse pipe, welding a 10cm long vertical pipe through the connecting hole, enabling the transverse pipe to be perpendicular to the vertical pipe, and arranging threads at the end part of the vertical pipe; the two ends of the horizontal tube are inserted into the hose and sealed, and are fixed by binding wires. The utility model discloses if another mouthful also can smoothly slip casting of a mouthful jam, avoided slip casting pipe blocking phenomenon. The utility model discloses convenient to use uses manpower sparingly, material resources, improves and becomes stake quality, shortens corresponding time limit for a project and improves the engineering profit space.

Description

Three-way joint of grouting pipe

Technical Field

The utility model belongs to the building field mainly forms a complete set with the slip casting pipe.

Background

In recent years, the high-rise buildings in China are rapidly developed, the requirement on the bearing capacity of a foundation is higher and higher, and in order to meet the design requirement and ensure the bearing capacity of a pile foundation to be improved, the pile foundation of a building is generally designed with a post-grouting construction process. In the post grouting construction, the bottom sealing of the pile bottom grouting pipe is provided with a capsule type and a hose type, and the pile side is only provided with the hose type. In the process of pouring pile foundation concrete, the concrete easily wraps the grouting pipe, the bottom sealing hose cannot be opened by the pressure of the grouting pump, so that cement grout cannot be injected, and the bearing capacity of the foundation cannot meet the design requirement.

If the grouting pipe is blocked, not only is the labor wasted, but also the pile forming quality is influenced. Therefore, how to prevent the post-grouting pipe from being blocked is a necessary quality control measure in the current pile foundation construction.

Disclosure of Invention

In order to solve the jam of back slip casting pipe, the bearing capacity can not reach the problem of design requirement phenomenon, the utility model provides a convenient to use, labour saving and time saving can prevent that back slip casting pipe from blockking up, guarantees going on smoothly of back slip casting.

The technical scheme of the invention is as follows: the three-way joint of the grouting pipe is characterized by consisting of a transverse pipe, a vertical pipe, a screw thread, a hose and a binding wire; drilling a connecting hole with the diameter of 2cm in the middle of a 13cm long transverse pipe, welding a 10cm long vertical pipe through the connecting hole, enabling the transverse pipe to be perpendicular to the vertical pipe, and arranging threads at the end part of the vertical pipe; the two ends of the horizontal tube are inserted into the hose and sealed, and are fixed by binding wires.

The utility model discloses a use method: will the utility model discloses a standpipe is connected with slip casting pipe screw thread to closely transfer along with the steel reinforcement cage with the main muscle ligature of steel reinforcement cage together. The pile bottom of each pile is provided with 2 or 3 grouting pipes (the diameter of the pile is less than 1000mm, 2 grouting guide pipes are arranged, the diameter of the pile is more than 1000mm, 3 grouting guide pipes are arranged, and the grouting pipes are specifically determined according to the setting requirement). According to the geological and bearing capacity requirements, pile side grouting needs to be set for enhancing the grouting effect. The grouting slurry pipes are connected through screw threads, so that welding is avoided. The bottom of the grouting pipe is preferably extended out of the reinforcement cage by more than 10 cm.

The utility model discloses if another mouthful also can smoothly slip casting of a mouthful jam to slip casting pipe blocking phenomenon has been avoided.

The utility model discloses convenient to use, because the pipe blockage increases manpower, material resources when avoiding slip casting, shortens corresponding time limit for a project and improves engineering profit space.

Drawings

Fig. 1 is a structural diagram of a three-way joint according to embodiment 1 of the present invention.

Fig. 2 is a diagram of the three-way joint according to embodiment 1 of the present invention.

Fig. 3 is a position diagram of the three-way joint according to embodiment 1 of the present invention.

In the figure, the device comprises a transverse pipe 1, a transverse pipe 2, a vertical pipe 3, a screw thread 4, a grouting pipe 5, a three-way joint 6, a bottom sealing hose 7, a binding wire 8 and a reinforcement cage.

Detailed Description

Example 1: as shown in fig. 1, the three-way joint of the grouting pipe is characterized by comprising a horizontal pipe 1, a vertical pipe 2, a screw thread 3, a bottom-sealing hose 6 and a binding wire 7. The horizontal pipe 1 (firstly, a hole with the diameter of 2cm is drilled in the middle of the pipe) is welded with the vertical pipe 2, and the top of the vertical pipe is connected with a threading device 3. Finally, bottom-sealing hoses 6 are inserted into the two ends of the transverse pipe and fixed by binding wires 7.

Example 2: the utility model discloses when using with the cooperation of slip casting pipe 4, with

slip casting pipe

4 and 5 for the screw thread connection of three way connection and with the inseparable ligature of steel reinforcement cage 8 transfer along with the steel reinforcement cage together.
