[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The present application embodiment discloses a grouting material proportioning machine for tunnel construction (hereinafter referred to as proportioning machine). Figure 1 and Figure 2 The grouting material proportioning machine for tunnel construction includes a conveying pipe 1, a conveying mechanism 2, a quantitative mechanism 3, a valve 4 and a transfer mechanism 5.

[0037] like Figure 3 As shown, a heating component 7 is provided on the surface of the conveying pipe 1, and the heating component 7 includes a heating layer 71 and an insulating layer 72. The heating layer 71 covers the surface of the conveying pipe 1 and is electrically connected to the power supply. The heating layer 71 is used to heat the conveying pipe 1, thereby heating the grouting material in the conveying pipe 1 to ensure that the grouting material melts and its performance is not affected by too low temperature during transportation; the insulating layer 72 is provided between the heating layer 71 and the conveying pipe 1, and the insulating layer 72 is used to separate the heating layer 71 and the conveying pipe 1, thereby providing electrical insulation for the heating layer 71 to prevent the heating layer 71 from being charged and causing the conveying pipe 1 to be charged, thereby reducing possible safety hazards.

[0038] Optionally, in an embodiment of the present application, the insulating layer 72 covers the entire outer surface of the heating layer 71 to isolate the influence of the external environment on the heating layer 71, thereby extending the service life of the heating layer 71 and reducing damage to the heating layer 71 caused by environmental factors; the heating layer 71 is specifically a thick film heating film.

[0041] Optionally, a baffle 34 is provided on one side of the screen 33, and the baffle 34 can prevent the grouting material from overflowing from the opening of the first barrel 31 due to excessive addition or vibration of the screen 33 when the grouting material passes through the screen 33, thereby keeping the construction environment clean and safe; the operator can pull out the screen, check the status of the screen 33, and promptly discover and solve possible blockages or other problems, such as whether the screen 33 is damaged, deformed or worn, or whether the pores of the screen 33 are blocked by lumps or large particles in the grouting material. Pulling out the screen 33 can quickly clear these blockages and restore the screening efficiency. The screen 33 can even be replaced when the screen 33 is seriously damaged or needs to be replaced with a screen 33 of different apertures to accommodate grouting materials of different particle sizes.
