[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] like Figure 1 、 2As shown in Figures 3 and 4, a high-speed railway ballastless track CPⅢ measuring device is characterized by: a contact network column foundation (1) is a contact network column foundation, which mainly stabilizes the CPⅢ foundation; a CPⅢ column foundation (2) is a CPⅢ column foundation, which is connected with the contact network column foundation (1) and the CPⅢ column foundation (2) to ensure the stability of the CPⅢ column foundation; the CPIII column bottom steel plate (3) is an 8mm galvanized steel plate, the stainless steel sleeve (5) is a 20mm stainless steel sleeve, and the stainless steel pipe (7) is a 120mm*300mm*5mm stainless steel pipe. The CPIII column bottom steel plate (3), the stainless steel pipe (7), and the stainless steel sleeve (5) are welded into a whole. When in use, the entire CPⅢ column is connected through the anchor bolts embedded in the CPⅢ column foundation; the embedded anchor bolts (6) are embedded anchor bolts, a total of 4; and the fixing bolts (4) are fixing bolts, which fix the entire CPⅢ column to the CPⅢ column foundation (2) through the fixing bolts.
[0021] The contact network column foundation (1) and the CPⅢ column foundation (2) are connected together by internal steel bar connecting rods during the pouring of concrete to ensure the stability of the concrete foundation of the CPⅢ column foundation (2).
[0022] The stainless steel pipe (7) is prefabricated with a galvanized stainless steel column, and the CPIII column bottom steel plate (3) and the stainless steel sleeve (5) are welded into a whole. During installation, four fixing bolts (4) and pre-buried anchor bolts are used for fixing.
[0023] The top of the stainless steel pipe (7) is sealed with stainless steel to form a conical drainage slope. The stainless steel pipe (7) is prefabricated with stainless steel columns, which changes the traditional PVC pipe to be poured with concrete, making it more economical, stable and beautiful.
[0024] The welding position of the stainless steel sleeve (5) and the stainless steel pipe (7) is 30cm below the top of the stainless steel and welded facing the line. The slope of the stainless steel sleeve (5) is set to 1:10 reverse slope to ensure that the CPⅢ prism rod slides out during measurement.
[0025] The utility model is realized by adopting the following technical solutions:
[0026] The contact network column foundation (1) and the CPⅢ column foundation (2) are the contact network support foundation and the CPⅢ column foundation respectively. When constructing the contact network column foundation, it is constructed together with the CPⅢ column foundation. At the same time, the four embedded anchor bolts (6) are accurately placed in the CPⅢ column foundation. The four anchor bolts are welded and fixed to the main reinforcement of the foundation.
[0027] After the concrete is poured and the concrete strength reaches 80% of the design, the prefabricated CPⅢ measuring device will be installed. During installation, the CPⅢ sleeve is located on the line side, and a spirit level is used to measure the verticality. When it is less than 3‰, it is fixed with bolts. When measuring, the CPⅢ sleeve cover on the column is removed and the CPⅢ prism is installed for measurement.
[0028] The stainless steel sleeve (5) is a CPIII prism, which mainly reflects the total station signal; No. 7 is a CPIII galvanized steel column, which mainly fixes the CPIII prism sleeve together through the CPIII column foundation; the CPIII column bottom steel plate (3) is a CPIII column bottom steel plate, which mainly welds the column to the steel plate and then connects and fixes it with the steel plate through embedded bolts, finally forming a high-speed railway ballastless track CPIII measurement device.
