[0010] The dam shoulder of the dam body corresponds to the bottom of the concrete chute, and the dam body is between the two mountain bodies.

[0011] The concrete chute is composed of a corrugated pipe cut in half, and the concrete chute has a semicircular annular hole.

[0012] The support frame assembly comprises a vertical rod inserted into the slope surface and knocked, and the vertical rod is distributed on both sides of the concrete chute at intervals;

[0013] A longitudinal bottom rod connected to the vertical rod, which is distributed longitudinally;

[0014] A transverse bottom rod distributed transversely and contacting the bottom surface of the concrete chute;

[0015] A pull ring penetrating the annular hole of the concrete chute, the pull ring has a sleeve ring fixed at both ends, and the sleeve ring is fixed on the vertical rod.

[0016] The longitudinal bottom rod is fixed with the horizontal bottom rod through a pipe buckle; and the horizontal bottom rod is fixed with the vertical rod through a pipe buckle.

[0017] The loop and the pull ring are integrally formed at both ends.

[0018] The pull ring and the loop are made of a force-bendable metal steel rope.

[0019] The beneficial effect of the present application is that the annular holes at different sections of the concrete chute pass through the pull ring, the pull ring is sleeved on the vertical rod at both ends and fixed, when the concrete conveying vehicle on the transportation road pours the concrete into the concrete chute on the inclined surface, the pull ring at different sections of the concrete chute can disperse and transmit the impact through the vertical rod to the inclined surface, thereby solving the problem that the gravel in the concrete will impact the chute surface and easily cause the unstable installation state of the concrete chute when a large amount of concrete is conveyed.

[0024] The technical scheme of the present application is further described below, but the scope of protection is not limited to the description.

[0025] As Figs. 1-2 shown.

[0026] The distribution structure of the dam body side dam shoulder concrete pouring of the present application comprises:

[0027] The inclined surface 11 is obtained by excavating the mountain 1, and the transportation road 12 is provided on the top of the inclined surface 11 for the concrete conveying vehicle to walk.

[0028] The concrete chute 2 is supported and installed on the inclined surface 11 through the support frame assembly 3, and the concrete chute 2 is obliquely installed on the inclined surface 11.

[0029] The bottom of the concrete chute 2 corresponds to the dam shoulder 41 construction area of the dam body 4, and the dam body 4 is between the two mountains 1.

[0030] The concrete chute 2 is composed of a corrugated pipe cut in half, so that the concrete chute 2 has a semicircular annular hole.

[0031] The support frame assembly 3 comprises vertical rods 31 inserted into the inclined slope surface 11, which are spaced apart on both sides of the concrete chute 2;
