Referring to fig. 1 and 2, the utility model discloses an underground pipeline's mounting structure, including bed course 1 and the drain pipe 2 of tiling on bed course 1 upper surface. The water discharge pipe 2 is formed by splicing a plurality of pipe joints 21 in an end-to-end butt joint mode. The upper surface of the cushion layer 1 is provided with a cushion seat 12 at a position opposite to each pipe joint 21 of the water discharge pipe 2, and the cushion seat 12 is fixedly connected with the cushion layer 1. A V-groove 121 is provided along the axial direction of the pipe joint 21 on the upper surface of the shoe 12, and the pipe joint 21 is snapped into the V-groove 121.

The positions, which are located on the upper surface of the cushion layer 1 and are opposite to each pipe joint 21, are respectively provided with a T-shaped sliding groove 11, and the length direction of the T-shaped sliding grooves 11 is vertical to the axial direction of the pipe joints 21.

Referring to fig. 1 and 3, each T-shaped sliding groove 11 is provided with a limiting device 3, each limiting device 3 includes a vertical column 31 vertically disposed above the cushion layer 1, a T-shaped sliding block 34 matched with the T-shaped sliding groove 11 is disposed at the bottom end of each vertical column 31, and the T-shaped sliding blocks 34 and the vertical columns 31 are fixedly welded to each other. The T-shaped sliding block 34 extends into the T-shaped sliding groove 11 and is connected with the T-shaped sliding groove 11 in a sliding mode.

The area of the top end face of the T-shaped slider 34 is larger than the area of the bottom end face of the upright column 31, so that when the upright column 31 is butted with the T-shaped slider 34, an exposed face 341 is left on the top end face of the T-shaped slider 34, a threaded hole vertically penetrating through the T-shaped slider 34 is formed in the exposed face 341, and a locking bolt 35 is connected to the threaded hole in a threaded manner. By rotating the lock bolt 35, the lock bolt 35 is moved in the direction of the bottom end of the T-shaped slider 34, and the position of the T-shaped slider 34 is fixed.

The top end of the upright column 31 is provided with a limiting rod 32 which horizontally extends towards the direction of the opposite pipe joint 21, and the limiting rod 32 is fixedly connected with the upright column 31 by welding. The end of the restraining bar 32 remote from the upright 31 is the free end of the restraining bar 32. When the column 31 moves along the T-shaped chute 11 in a direction to approach the pipe joint 21, the column 31 can come into contact with the pipe joint 21. When the upright 31 slides along the T-shaped chute 11 to abut against the opposite pipe joint 21, the restricting rod 32 is positioned right above the pipe joint 21 and the bottom end surface of the restricting rod 32 abuts against the top end surface of the pipe joint 21. When the upright 31 moves away from the pipe joint 21 along the T-shaped chute 11, the restricting rod 32 can be in a misaligned state with the pipe joint 21.

The rubber pad 321 is adhered to the bottom end surface of the limiting rod 32, and the limiting rod 32 body and the pipe joint 21 can be separated through the rubber pad 321, so that when the pipe joint 21 floats upwards, the pipe joint 21 and the limiting rod 32 are prevented from being extruded, and the limiting rod 32 is prevented from damaging the surface of the pipe joint 21.

A stay 33 is arranged between the limiting rod 32 and the upright 31, and two ends of the stay 33 are respectively fixedly connected with the limiting rod 32 and the upright 31 by welding. A triangular area is enclosed between the restraining bar 32, the upright 31 and the brace 33.

The length of the upright column 31 is adjustable, the upright column 31 comprises a movable rod 312 and a fixed rod 311 which are arranged up and down oppositely, a double-head positive and negative tooth screw 313 is arranged between the movable rod 312 and the fixed rod 311, and two ends of the double-head positive and negative tooth screw 313 are respectively in threaded connection with the movable rod 312 and the fixed rod 311. When the double-ended positive and negative threaded screw is rotated, the movable rod 312 and the fixed rod 311 can be controlled to relatively move closer to or away from each other. A guide rod 3121 parallel to the double-headed positive and negative threaded rod 313 is further disposed between the moving rod 312 and the fixed rod 311, one end of the guide rod 3121 is welded to the moving rod 312, and the other end of the guide rod 3121 is inserted into the fixed rod 311 and slidably connected to the fixed rod 311. An insertion hole 3111 into which the guide bar 3121 is inserted is formed at a position on the fixing lever 311 opposite to the guide bar 3121.

The double-headed positive and negative threaded rod 313 is located on the side of the guide bar 3121 facing away from the opposite pipe section 21.

An operating portion 3131 having a regular hexagonal cross section is provided at a middle position in the axial direction of the double-headed positive and negative-teeth screw 313, and the rotation of the double-headed positive and negative-teeth screw 313 is facilitated by the operating portion 3131.

The restraining bar 32 and the stay 33 are connected to the moving bar 312 of the column 31. By adopting the upright column 31 with adjustable length, when the appearance of the pipe joint 21 has errors due to production, the position of the limiting rod 32 can be adjusted, so that the limiting rod 32 can be ensured to be pressed against the top end of the pipe joint 21.

The implementation principle of the embodiment is as follows: before laying the drain pipe 2, the limiting device 3 is moved to one end of the T-shaped sliding groove 11 far away from the required installation position of the drain pipe 2, and then the pipe joints 21 are placed in the V-shaped grooves of the base 12, and the adjacent pipe joints 21 are butted end to end. After the drain pipe 2 is laid, the movable limiting device 3 moves towards the drain pipe 2, so that the limiting rod 32 is pressed on the end face of the top end of the opposite pipe joint 21, and the pipe joint 21 is limited to float upwards when concrete is poured.
