DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application.

[0032] An embodiment of the temporary supporting mechanism for road drainage construction according to the present application is shown in Figures 1 to 12 .

[0033] The temporary supporting mechanism for road drainage construction is used for supporting a trench, the trench extends along a horizontal direction, the extension direction of the trench is referred to as a first direction, and the temporary supporting mechanism comprises a plurality of supporting units 100, the plurality of supporting units 100 are sequentially arranged along the first direction in the trench, and every two supporting units 100 arranged adjacently in the first direction can be arranged in a central symmetry or sequentially arranged.

The size of the first supporting plate 110 in the first direction is greater than the size of the second supporting plate 120 in the first direction. The first side plate 111 and the second side plate 121 are both arranged obliquely and face to face in the second direction, and the first side plate 111 and the second side plate 121 on the same side in the first direction are coplanar. The first side plate 111 of one of the supporting units 100 can abut against the second side plate 121 of another supporting unit 100 arranged adjacent to it in the first direction. The first supporting plate 110 and the second supporting plate 120 are provided with a first supporting piece 130 and a second supporting piece 140, the first supporting piece 130 and the second supporting piece 140 are arranged in sequence in the first direction, and the first supporting piece 130 and the second supporting piece 140 can move closer to or farther away from each other in the first direction.

The rotating disc 300 is provided with a clamping groove 320 on the end face close to the first support arm 131 in the second direction, the clamping groove 320 is coaxially arranged with the rotating disc 300, the locking plate 400 is provided with a clamping plate 420 close to one end of the clamping groove 320 in the first direction, the clamping plate 420 is arranged perpendicular to the locking plate 400, so that the locking plate 400 and the clamping plate 420 form an L-shaped structure. In the initial state, the first elastic member 410 makes the clamping plate 420 clamped with the outer wall surface of the clamping groove 320.

[0051] Specifically, the rotating disc 300 is coaxially and fixedly connected with a rotating column 330, the first support plate 110 and the second support plate 120 are each provided with a through hole 112, the rotating column 330 passes through the through hole 112 along the second direction, and the rotating column 330 is inserted with a locking pin 340 for restricting the rotating column 330 from being separated from the first support plate 110 and the second support plate 120.

[0052] In the initial state, the locking plate 400 extends out of the first side plate 111 of the first support plate 110 and the second side plate 121 of the second support plate 120 in the first direction, and at this time, the clamping plate 420 is clamped with the outer wall surface of the clamping groove 320 under the action of the first elastic member 410, that is, the rotation of the rotating disc 300 is limited by the locking plate 400, and the locking member is in the locked state.

[0053] After the support unit 100 is continuously lowered into the trench, the soil on the side wall of the trench will generate an upward force on the guide strip 310, and the component of the force in the first direction will promote the guide strip 310 and the first support plate 110 or the second support plate 120 to move in the first direction to the side of the other support unit 100 arranged adjacent to it, and assist the abutment of the first side plate 111 and the second side plate 121 arranged adjacent in the first direction, until the guide strip 310 is rotated to the vertical state.

[0054] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
