[0002] Externally flared concrete pipes are often used in municipal drainage pipe construction. An externally flared section is set at one end of the externally flared concrete pipe. During construction, adjacent concrete pipes are socketed with each other, that is, the externally flared section of one concrete pipe is inserted into the outside of the thinner end of another concrete pipe.

[0003] At present, for the on-site socket-and-spigot construction of such externally flared concrete pipes, a cushion layer is usually laid in advance in the construction area. In some working conditions, the sockets are directly spliced ​​one by one after the cushion layer is laid out, and the externally flared section is directly placed on the cushion layer. After the socket-and-spigot, a wedge is inserted into the side of the externally flared concrete pipe to prevent it from rolling. In some working conditions, such as the municipal drainage pipe laying structure and cushion block disclosed in the invention patent with publication number CN219327162U, cushion blocks are added to the cushion layer to support the externally flared concrete pipe.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0027] In the present invention, if Figure 1-3 As shown, a construction structure of an externally expanded concrete pipe is provided, which is used to install an externally expanded concrete pipe. The externally expanded concrete pipe includes a cylindrical pipe body 1 and a flared section 2 formed at one end of the pipe body 1. The end of the pipe body 1 away from the flared section 2 can be inserted into the inner side of the flared section 2 of another externally expanded concrete pipe, and includes a first support seat 3 and a second support seat 4. The top surface of the first support seat 3 is provided with a first arc groove 5, and the top surface of the second support seat 4 is provided with a second arc groove 6; the first support seat 3 has a first connecting portion 7, and the second support seat 4 has a second connecting portion 8. When the adjacent pipe body 1 and the flared section 2 are inserted, the externally expanded concrete pipe where the flared section 2 is located can be placed in the first arc groove 5, and the externally expanded concrete pipe where the pipe body 1 is located can be placed in the second arc groove 6, and the first connecting portion 7 of the first support seat 3 can be connected to the second connecting portion 8 of the second support seat 4; the first support seat 3 and the second support seat 4 can be connected to the externally expanded concrete pipe.

[0028] When the construction structure of the present invention is being constructed, the second support seat 4 and the first support seat 3 are first placed in the direction away from the already inserted concrete pipe at the position where the concrete pipe is to be inserted. At this time, the newly inserted concrete pipe can be placed on the first support seat 3 and the second support seat 4, and the newly inserted concrete pipe is axially moved at the same time. During the movement, the newly inserted concrete pipe synchronously drives the adjustment of the position of the first support seat 3 to perform the socket connection between the newly inserted concrete pipe and the already inserted concrete pipe. After the socket connection is completed, as shown in the figure, the position of the second support seat 4 can be fine-tuned at this time, so that the second support seat 4 can be matched and connected with the first support seat 3 at the position of the already inserted concrete pipe, and the second support seat 4 at this position is connected with the corresponding newly inserted concrete pipe, and the first support seat 3 is connected with the newly inserted concrete pipe at the corresponding position. At this time, the socket position of the newly inserted concrete pipe and the already inserted concrete pipe can be sealed by grouting. At this time, the next newly inserted concrete pipe can be installed.

[0029] The technical advantages of the present invention are as follows: First, by such a configuration, the two sections of concrete pipes can be laterally limited by means of the first support seat 3 and the second support seat 4 on both sides of the socket position of the concrete pipe, and the first support seat 3 is connected to the concrete pipe at the corresponding position, and the second support seat 4 is connected to the concrete pipe at the corresponding position, to provide axial constraints to the concrete pipe that has completed the socket. In this way, when the newly inserted concrete pipe is socketed again, the axial loosening of the inserted concrete pipe caused by the impact on the inserted concrete pipe during the socket process can be reduced, thereby maintaining the sealing stability of the socket position of the inserted concrete pipe. Second, after the overall completion of the socket construction, the adjacent concrete pipes can be connected at the socket position through the first support seat 3 and the second support seat 4, which can further stabilize the stability of the axial socket, so as to maintain the stability of the concrete pipe socket when micro-deformation of the formation and vibration disturbance occur, and further maintain the sealing effect.

[0030] In the embodiments of the present invention, in order to better describe the implementation process, the outward-flared concrete pipe is divided into a newly inserted concrete pipe and an already inserted concrete pipe at different stages. The specific basis for the distinction is that the already inserted concrete pipe is the one that has completed the socket and the first support seat 3 and the second support seat 4 at the corresponding position are respectively connected to the concrete pipe, and the newly inserted concrete pipe is the one that is in the adjustment and moving state during the construction process.

[0031] In a preferred embodiment, for the structure of the present invention, to be more specific, the first supporting seat 3 protrudes from the side of the flared section 2 to form the first connecting portion 7; the second supporting seat 4 is formed with a second connecting portion 8 that can be plugged into and fit with the first connecting portion 7.

[0032] As shown in the figure, by plugging and fitting the second connecting part 8 into the first connecting part 7, after the first support seat 3 and the second support seat 4 are connected, the constrained connection between the first support seat 3 and the second support seat 4 can be further stabilized to prevent the first support seat 3 and the second support seat 4 from lateral displacement.

[0033] As shown in the figure, the second connecting part 8 can be inserted on the outside of the first connecting part 7, so as to further ensure the coaxiality of the two sections of concrete pipes when connecting.

[0034] In a preferred embodiment, for the connection between the first support seat 3 and the second support seat 4 in the structure of the present invention, more specifically, the first support seat 3 is provided with a first connecting hole, and the second support seat 4 is provided with a second connecting hole; the construction structure also includes a first bolt 9, which can pass through the first connecting hole and the second connecting hole and fix the first support seat 3 and the second support seat 4.

[0035] As shown in the figure, after the newly inserted concrete pipe is inserted and plugged, the lateral position of the second support seat 4 and the cushion layer is relatively fixed. At this time, the second support seat 4 can be moved toward the direction of the inserted concrete pipe to make the first connection part 7 and the second connection part 8 plug in, and then the first support seat 3 and the second support seat 4 are connected by the first bolt 9. Then, the first support seat 3 is connected to the concrete pipe at the corresponding position, and the second support seat 4 is connected to the concrete pipe at the corresponding position.

[0036] In a preferred embodiment, for the structure of the present invention, more specifically, the first arc groove 5 includes a cylindrical section 501 capable of cooperating with the side of the tube body 1 and a deformation section 502 capable of cooperating with the side of the expansion section 2 .

[0037] As shown in the figure, after the first support seat 3 is connected to the concrete pipe, the deformation section 502 and the expansion section 2 cooperate to increase the difficulty of the first support seat 3 moving toward the new concrete pipe, thereby further improving the axial constraint effect after the first support seat 3 is connected to the concrete pipe at the corresponding position.

[0038] In a preferred embodiment, with regard to the connection method between the second support seat 4 and the concrete pipe in the structure of the present invention, to be more specific, the construction structure also includes a second fixing hoop plate 10, which can be connected to the second support seat 4 and clamped and fixed on the pipe body 1.

In this way, the friction between the second fixing hoop plate 10 and the second support seat 4 and the concrete pipe can be used to axially constrain the newly inserted concrete pipe to prevent the newly inserted concrete pipe from loosening in the axial direction.

[0040] In a preferred embodiment, for the structure of the present invention, further specifically, the second fixing hoop plate 10 includes an arc segment 1001 that can cooperate with the side of the tube body 1, and a connecting segment 1002 respectively connected to both sides of the arc segment 1001, and the connecting segment 1002 can be connected to the second support seat 4 so that the arc segment 1001 and the inner surface of the second arc groove 6 can clamp and fix the tube body 1.

[0041] As shown in the figure, the second fixing hoop plate 10 can be conveniently clamped on the outside of the tube body 1 from top to bottom, reducing the difficulty of assembling the second fixing hoop plate 10 and the tube body 1. The arc segment 1001 can also be used to provide a downward restraining force to the tube body 1, and the second arc surface of the second support seat 4 can be used to provide an upward supporting force to the tube body 1.

[0042] In a preferred embodiment, for the structure of the present invention, to be more specific, the second support seat 4 is provided with a slot 11 for the connecting section 1002 to be inserted, the connecting section 1002 is provided with a connecting hole, the second support seat 4 is provided with a threaded hole in the slot 11, and the construction structure further includes a second bolt 12, the second bolt 12 can pass through the connecting hole and be fixed in the threaded hole. As shown in the figure, the second fixing hoop plate 10 and the second support seat 4 can be connected by the second bolt 12, and the pressing force of the second bolt 12 on the connecting section 1002 can be adjusted to adjust the pressing force of the arc segment 1001 on the pipe body 1, so as to maintain the fixing effect of the arc segment 1001 and the second arc groove 6 on the pipe body 1, and prevent the pipe body 1 from being crushed.

[0043] In a preferred embodiment, for the structure of the present invention, to be more specific, the inner surface of the first arc groove 5 and / or the inner surface of the second arc groove 6 is provided with a rubber strip groove 13, and the construction structure also includes a rubber strip 14 arranged in the rubber strip groove 13.

[0044] As shown in the figure, by setting the rubber strip groove 13, a rubber strip 14 can be set in the rubber strip groove 13 to further improve the friction between the arc segment 1001 or the corresponding second arc groove 6 and the tube body 1, and further improve the axial restraint force on the tube body 1.

[0045] In the embodiment of the present invention, for the setting of the second fixing hoop plate 10, it is preferred to use the second fixing hoop plate 10 made of concrete building material, and for the connection structure between the bottom of the connecting section 1002 and the second support seat 4, it is preferred that a transversely extending boss is provided at the bottom of the connecting section 1002, and the boss is provided with a connecting hole, and the connecting section 1002 is pre-embedded with a metal reinforcing member at the boss position, and the metal reinforcing member forms a reinforcement structure of the boss and the connecting section 1002.

[0046] The structural arrangement of the second fixing hoop plate 10 is not limited to the form of the concrete structural component shown in the figure. In an optional embodiment, a metal second fixing hoop plate 10 or an engineering plastic second fixing hoop plate 10 can also be selected.
