[0002] Reinforced concrete circular pipe is commonly known as cement pipe, which is a commonly used pipe fitting in municipal water conservancy projects.

[0003] At present, most reinforced concrete circular tubes are provided with a cone-shaped structure at the head and a cone-shaped sleeve structure at the tail for the convenience of connection. During assembly, the head of the circular tube is inserted into the inner side of the tail to achieve the effect of connecting and assembling multiple reinforced concrete circular tubes. However, during the installation process, since the reinforced concrete circular tube itself is heavy and the diameter of the tail of the circular tube is larger than the diameter of the head, it is necessary to use an external hoist to lift the circular tube so that the head of the subsequent circular tube can be smoothly inserted into the inner side of the tail of the previous circular tube.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The reinforced concrete circular tube with a base involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0024] Reference Figure 1-4 The utility model provides a reinforced concrete circular tube with a base, including a base plate 1 and a circular tube body 2. The left end of the circular tube body 2 is provided with an inclined surface 21, and the right end of the circular tube body 2 is provided with a conical sleeve 22. The inclined surface 21 is adapted to the inner wall of the conical sleeve 22.

[0025] When assembling multiple sections of concrete circular tubes inside a tunnel, use an external lifting device to lift the circular tube body 2 to the tail of the previous circular tube body 2 in advance, and ensure that the head and tail of the circular tube body 2 correspond. Then, insert the head of the subsequent circular tube body 2 into the tail of the previous circular tube body 2. By setting the inclined surface 21 and the tapered sleeve 22 and adapting the inclined surface 21 and the tapered sleeve 22, the tightness of the connection of the circular tube body 2 can be improved.

[0026] Positioning plates 12 are welded to both the front and rear sides of the base plate 1 , and positioning tabs 13 are inserted into the surface of the positioning plates 12 .

[0027] By providing the positioning plate 12 and the positioning plug 13, after roughly adjusting the position of the circular tube body 2 to be assembled, the positioning plug 13 is inserted into the ground to firmly position the base plate 1, thereby avoiding displacement of the base plate 1 during assembly.

[0028] A connecting plate 3 is arranged on the top of the base plate 1 , the circular tube body 2 is arranged above the connecting plate 3 , a height adjustment component is arranged between the base plate 1 and the connecting plate 3 , and a pushing joint component is arranged between the connecting plate 3 and the circular tube body 2 .

[0029] The height adjustment assembly includes two side plates 4 symmetrically welded to the bottom end of the connecting plate 3 , a forward and reverse threaded screw 5 is rotatably connected between the two side plates 4 , and a driving assembly for driving the forward and reverse threaded screw 5 is arranged on the surface of the front side plate 4 .

[0030] The driving assembly includes a driving box 15 fixedly mounted on the front side of the side plate 4 , and a knob 16 for driving the forward and reverse threaded screw 5 to rotate is rotatably connected to the left side of the driving box 15 .

[0031] The knob 16 is fixedly mounted with a worm 17 on the surface inside the drive box 15 , the forward and reverse threaded screw 5 is rotationally connected to the drive box 15 , and the end of the forward and reverse threaded screw 5 extends into the interior of the drive box 15 and is fixedly mounted with a worm wheel 18 , and the worm 17 is meshed with the worm wheel 18 .

[0032] The surface of the positive and negative thread screw 5 is symmetrically threadedly connected with two sliders 6 , the bottom ends of the two sliders 6 are rotatably connected with support plates 7 , and the bottom ends of the two support plates 7 are rotatably connected to the upper surface of the base plate 1 .

[0033] The advancing joint assembly includes bosses 8 symmetrically fixedly installed on the front and rear sides of the circular tube body 2, an anti-slip disc 9 is welded to the end of the boss 8 away from the circular tube body 2, and two brackets 10 are symmetrically welded to the top of the connecting plate 3, and the surfaces of the brackets 10 are provided with limiting sliding grooves 11 for the boss 8 to slide.

[0034] Furthermore, when assembling the circular tube body 2, ensure that the head and tail of the circular tube body 2 correspond to each other. By setting a height adjustment component, the base plate 1 is tightened against the bottom of the pit. By turning the knob 16, based on the engagement of the worm 17 and the worm wheel 18, the positive and negative threaded screws 5 can be driven to rotate, thereby moving the two sliders 6. The support plate 7 is used to support the connecting plate 3 and the base plate 1, and the head height of the circular tube body 2 is finely adjusted to match the tail height of the previous circular tube body 2. Subsequently, the seam advancing component is used, and the tail of the circular tube body 2 is lifted by an external lifting device. Then, the boss 8 is used to slide inside the limiting slide groove 11, and the head of the circular tube body 2 can be very conveniently inserted into the tail of the previous circular tube body 2, thereby achieving a quick assembly effect.

[0035] It is worth noting that, when the lifting equipment is used for the subsequent lifting, the head of the circular tube body 2 is limited, which reduces the shaking effect of the circular tube body 2, thereby reducing the difficulty of assembly and improving the efficiency of assembly.

[0039] When the two circular tube bodies 2 are assembled and connected by using the pushing joint assembly, by rotating the adjusting screw 19, the pushing plate 20 can be driven to squeeze the boss 8 to the left, thereby driving the circular tube body 2 to move to the left, thereby facilitating the adjustment of the tightness of the connection between the two circular tube bodies 2.

[0040] It is worth noting that, at the beginning of assembly, the boss 8 is pre-controlled to be located at the rightmost side of the limiting slide groove 11 , so as to reserve space for the boss 8 to move leftward inside the limiting slide groove 11 .

[0041] A traction rod 23 for bolting an external rope is fixedly mounted on the surface of the circular tube body 2 .

[0042] It is worth mentioning that when it is inconvenient to use lifting equipment to lift the tail of the circular tube body 2 to be assembled, a traction rope and an electric hoist are bolted to the traction rod 23 on the surface of the previous circular tube body 2, and then the other end of the rope is connected to the boss 8 of the next circular tube body 2. By utilizing the pulling effect of the electric hoist on the next circular tube body 2, the tightness of the assembly connection of the circular tube body 2 can be further improved, and the assembly method of the circular tube body 2 is expanded, making the installation method flexible.

[0043] Finally, it should be noted that the drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention, and other structures may refer to the usual design. In the absence of conflict, the same embodiment and different embodiments of the present invention may be combined with each other.
