Embodiment 1

[0034] Embodiments of the present invention provide a small conduit grouting communication device, such as figure 1 As shown, it includes a connecting device 1 , a grouting pipe 2 and a small conduit 3 , and the small conduit 3 and the grouting pipe 2 are connected through the connecting device 1 .

[0035] Such as figure 2 As shown, the connecting device 1 includes an anti-slip joint 1-1, a positioning gear 1-2, a fixed plate 1-3, a bolt joint 1-4 and a nut, one end of the anti-slip joint 1-1 is connected to the bolt joint 1-4, and the bolt Install nuts on connectors 1-4. A fixed plate 1-3 is installed between the end of the anti-slip joint 1-1 connected to the bolt joint 1-4, and a plurality of positioning gears 1-2 are arranged at intervals along the outer side of the anti-slip joint 1-1.

[0036] Further, the anti-slip joint 1-1 has a hollow pipe inside, and the hollow pipe communicates with the inside of the bolt joint 1-4, thereby communicating with the grouting pipe ...

Embodiment 2

[0041] This embodiment provides a small conduit grouting system, including grouting equipment and the small conduit grouting communication device described in Embodiment 1, and the grouting pipe is connected to the grouting equipment.

Embodiment 3

[0043] This embodiment provides a method for using a small conduit grouting communication device, including the following steps:

[0044] (1) Determine the ratio of the slurry. The design parameters of the slurry mix ratio are determined through the indoor slurry mix ratio test.

[0045] (2) Check the grouting equipment. Before grouting the small conduit 3 on site, check the availability of the grouting equipment (grouting pump and mixing tank) according to the site construction conditions.

[0046] (3) Measurement lofting and drilling. Carry out on-site stakeout according to the designed position of the small conduit 3, use a drilling rig to drill the hole, and install the small conduit 3 to the designed depth.

[0047] (4) The grouting device and connecting device are in place. Install the grouting equipment on the construction site and connect it. Then, the connecting device 1 is installed inside the small conduit 3 through the anti-slip joint 1-1 and the positioning g...

Abstract

The invention discloses a small guide pipe grouting communication device, a system and a method. According to the technical scheme, the small guide pipe grouting communication device comprises a connecting device, a grouting pipe and a small guide pipe, and the small guide pipe is connected with the grouting pipe through the connecting device; and the connecting device comprises an anti-skid connector, a plurality of positioning gears are fixed to the outer side of the anti-skid connector, and the positioning gears can be attached to the inner wall of the small guide pipe. The grouting pipe and the small guide pipe can be conveniently connected, repeated welding and cutting can be avoided, and end plugging can be conveniently conducted.

Description

technical field [0001] The invention relates to the field of construction engineering soil reinforcement construction, in particular to a small conduit grouting communication device, system and method. Background technique [0002] With the rapid development of domestic economy and traffic engineering, more and more highways, railway tunnels and subway projects are being or will be constructed soon. Due to the vast territory of our country, the complex and changeable geological conditions and the development of joints and fissures in the rock mass, the excavation of underground engineering will inevitably cause the deformation of the rock mass. [0003] To solve this problem, small conduit grouting is a common construction method to quickly increase the strength of surrounding rock and reduce the degree of fragmentation of surrounding rock, thereby inhibiting the deformation of surrounding rock. However, the inventor found that due to the smooth wall of the small conduit, i...
