DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the utility model provides a reinforced concrete drain pipe, as Figures 1-4 shown, which includes a drain pipe body 1. There is a corrosion-resistant layer 4 inside the drain pipe body 1. Fixed cylinders 7 are provided at the centers near the front and rear sides of the bottom of the drain pipe body 1. Ground plugs 8 are connected to the bottoms of the two fixed cylinders 7, and fixing components 6 are provided in the inner cavities of the two fixed cylinders 7; the two fixing components 6 include drive plates 61 located at the centers near the tops of the inner cavities of the two fixed cylinders 7, and the two drive plates 61 are symmetrically arranged front and back with the center of the inner cavity of the drain pipe body 1 as the axis of symmetry.

[0021] It should be noted that since the existing reinforced concrete drain pipes are weak in strength and poor in fixing stability, therefore, in order to solve the problems that occur during the use of the existing reinforced concrete drain pipes, this solution solves the problems of weak strength and poor fixing stability of the existing reinforced concrete drain pipes by the coordinated use of various components inside the drain pipe body 1 and by additionally providing fixing components 6 in the inner cavities of the two fixed cylinders 7.

[0022] In a further preferred embodiment of the utility model, as Figures 1-4As shown in the figure, connecting rods 62 are connected to both the front and rear sides of the two drive plates 61 near the centers of the left and right sides. At one end away from the center of the inner cavity of the adjacent fixed cylinder 7, several connecting rods 62 on the front and rear sides are movably connected to movable plates 63. At the center of the bottom of one side of several movable plates 63 on the front and rear sides close to the center of the inner cavity of the adjacent fixed cylinder 7, connecting shafts 65 are movably connected. At one end of the adjacent two connecting shafts 65 close to the center of the inner cavity of the adjacent fixed cylinder 7, a plug rod 64 is jointly connected. Through holes are provided at the centers of the left and right sides of the two fixed cylinders 7. At one side away from the center of the inner cavity of the fixed cylinder 7, the two plug rods 64 on the front and rear sides are movably connected in the adjacent through holes.

[0023] In this embodiment, when the staff wants to lay the reinforced concrete drain pipe, first, the staff connects several drain pipe bodies 1 end to end. Then, through the two ground plugs 8 on the drain pipe body 1, the adjacent two fixed cylinders 7 are inserted into the soil. Next, the staff drives the adjacent two drive plates 61 to move downward. When the adjacent two drive plates 61 move downward, they can drive the adjacent four movable plates 63 to gradually rotate towards the horizontal state, so that the adjacent four movable plates 63 can quickly push the adjacent two plug rods 64 out of the adjacent fixed cylinder 7 and insert them into the soil, thereby applying a horizontal force to the reinforced concrete drain pipe, and further fixing the reinforced concrete drain pipe, so that it can be firmly fixed on the ground for use.

[0024] In a further preferred embodiment of the present invention, as Figure 2 and 3 shown, electric telescopic rods 66 are provided at the bottoms of the two drive plates 61. The bottoms of the two electric telescopic rods 66 are respectively connected to the inner part near the center of the bottom of the adjacent fixed cylinder 7, and the tops of the two electric telescopic rods 66 are respectively connected to the bottom near the center of the adjacent drive plate 61.

[0025] In this embodiment, the staff starts the two electric telescopic rods 66 through an external power supply. The two electric telescopic rods 66 start to contract inward when powered on, so that the two electric telescopic rods 66 quickly drive the two drive plates 61 to move downward.

[0026] In a further preferred embodiment of the present invention, as Figure 1 shown, there is a joint 5 at the rear side of the drain pipe body 1. A connection hole is provided at the center near the front side of the inner cavity of the joint 5. The side wall of the drain pipe body 1 near the rear side is connected to the inner wall of the connection hole.

[0027] In this embodiment, by connecting the joint 5 at the rear side of the drain pipe body 1, it is beneficial to connect several drain pipe bodies 1 end to end through the joint 5 for use.

[0028] In a further preferred embodiment of the present utility model, as Figure 2 and 3 shown, at the positions near the centers of the tops of the two fixing cylinders 7, fixing rods 9 are respectively connected, and the tops of the two fixing rods 9 are respectively connected to the positions near the centers of the front and rear sides of the bottom of the drain pipe body 1.

[0029] In this embodiment, by connecting two fixing rods 9 to the tops of the two fixing cylinders 7, the two fixing cylinders 7 can be firmly connected to the front and rear sides of the bottom of the drain pipe body 1 through the two fixing rods 9 for use.

[0030] In a further preferred embodiment of the present utility model, as Figure 1 and 2 shown, there is a reinforcing layer 3 outside the corrosion-resistant layer 4, and the inner wall of the reinforcing layer 3 is connected to the outer wall of the corrosion-resistant layer 4. The outside of the reinforcing layer 3 is connected to a compressive layer 2, and the outside of the compressive layer 2 is connected to the inner wall of the drain pipe body 1.

[0031] In this embodiment, by connecting the compressive layer 2 and the reinforcing layer 3 inside the 1, the compressive layer 2 and the reinforcing layer 3 can enhance the strength of the reinforced concrete drain pipe, avoiding problems such as easy cracking or disintegration during hoisting and installation. At the same time, by connecting the corrosion-resistant layer 4 inside the drain pipe body 1, the possibility of damage to the reinforced concrete drain pipe can be reduced, thereby increasing the service life of the reinforced concrete drain pipe.
