[0017] In order to better understand the purpose, structure and function of the utility model, a tunnel pavement base template component of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1~Figure 4 As shown, a tunnel pavement base template assembly is continuously arranged above the tunnel invert along the tunnel length direction with an interval of the width of the gravel blind ditch layer, including two transverse support templates 1 arranged perpendicularly and parallel to the ditch, one end of the two transverse support templates 1 is against the ditch, and the other ends are vertically connected to the longitudinal support template 2, the two end ends of the longitudinal support template 2 are bayonet ends 21, and the bayonet ends 21 are provided with bayonet parts 3, the transverse support template 1 is opposite to the bayonet end 21 The position is a fixed section 11, and the fixed section 11 is provided with an opening corresponding to the end face of the bayonet end 21, and the bayonet part 3 passes through the opening and is fixed using a fixing part 4.

[0019] In this embodiment, the transverse support template 1 is made of 16# channel steel, and a vertical opening is cut at the end position as the fixing section 11, so that the opening can be vertically inserted into the 16# channel steel. The longitudinal support template 2 is made of 16# channel steel, and the bayonet 3 is made of 10mm round steel bars, which are processed into a U shape. The longitudinal support template 2 and the bayonet 3 are welded. After welding, the bayonet end 21 of the longitudinal support template 2 is spliced ​​with the fixing section 11 of the transverse support template 1. The fixing member 4 is an inverted triangular wedge-shaped wooden block. After splicing, the fixing member 4 is used to reinforce the gap in the bayonet 3 to make the fixation more reliable and firm.

[0020] The pavement base template assembly of this embodiment has a support template connected to a support rod, and the support rod is fixed to the ground by a connecting rod. The installation is simple and convenient, and the fixation is firm and not easy to deform. The range can be adjusted by using support templates of different sizes, and the application range is wide.

[0021] The implementation process of the utility model is as follows:

[0022] 1. Cut the 16# channel steel to a length of 480cm;

[0023] 2. Make a hole at the end of the truncated 16# channel steel. The hole size should be consistent with the vertical cross section of the 16# channel steel. The horizontal support template 1 is then completed.

[0024] 3. Process the 10mm round steel bar into a U-shape. The end of the U-shape should be equal to the inner opening of the 16# channel steel. The bayonet 3 is then completed.

[0025] 4. Weld the round steel bar clamping piece 3 to the cut 16# channel steel. The welding method is: point-to-point welding of the 16# channel steel end and the round steel bar end. The longitudinal support template 2 is completed.
