[0033] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] like Figure 5 A construction method for a straddle-type monorail PC track beam in a tunnel with a circular section as shown, comprising the following steps:

[0035] Step 1. Provide a self-deformable tire-type beam erecting machine 1 and a self-deformable tire-type beam transport vehicle 3 that can walk on curved surfaces;

[0036] Step 2: Install and fix the PC track beam 2 on the self-deformable tire-type beam transport vehicle 3, and drive the self-deformable tire-type beam erecting machine 1 into the circular cross-section tunnel 4 to be in place;

[0037] Step 3: The self-deformable tire-type beam transport vehicle 3 transports the PC track beam 2 into the self-deformable tire-type beam erecting machine 1. At this time, the self-deformable tire-type beam transport vehicle 3 is located in the transverse clamp holding device 14 below;

[0038] Step 4. Start the hoisting device 12 of the self-deformable tire-type beam-erecting machine 1 to lift the PC track beam 2. After the PC track beam 2 falls on the concrete anchor box base 5, start the transverse clamp of the self-deformable tire-type beam-erecting machine 1 The holding device 14 is used for horizontal adjustment, and at the same time, the self-deformable tire type beam transport vehicle 3 exits the circular cross-section tunnel 4;

[0039] Step 5. The self-deformable tire-type beam erecting machine 1 erects the PC track beam 2 according to the design and construction drawing, and the self-deformable tire-type beam transporter 3 returns to transport the next PC track beam 2;
