Technical Field

[0001] The present application relates to the technical field of aqueduct construction, and in particular to a prefabricated aqueduct body structure that is easy to install. Background Art

[0002] Aqueduct is a structure used to transport water, usually across rivers, streams or other terrain obstacles to ensure that water resources can flow smoothly to where they are needed, which helps to rationally utilize water resources and meet the water needs of multiple fields such as agriculture, industry and urban life. When building large aqueduct structures, prefabricated concrete troughs are usually used for splicing to improve the construction efficiency and quality of the aqueduct.

[0003] During the construction of the precast concrete trough body splicing structure, the frame columns used to support the trough body are cast first, that is, the bearing platform is cast on the ground first, and then the pillars are cast on the bearing platform. The cap beam is cast on the top of the pillar to complete the casting of the frame columns, and then the precast trough body is suspended between adjacent frame columns by a double crane, and the precast trough body is placed on adjacent cap beams. The above method is used to place the precast trough body section by section to form a continuous aqueduct.

[0004] Regarding the above-mentioned related technologies, when the prefabricated trough body is placed, it is difficult for the crane to control the position of the prefabricated trough body on the cap beam, resulting in the position of the prefabricated trough body being not accurate enough.

Figure 1 The prefabricated aqueduct body structure which is easy to install includes a frame column 1 and a trough body 2, and the trough body 2 is arranged on the top of the frame column 1. The frame column 1 includes a support column 11, a cap beam 12 and a tie beam 13. Two support columns 11 are symmetrically arranged along the laying direction of the trough body 2. The cap beam 12 is a rectangular beam body, and the cap beam 12 is located on the top of the two support columns 11. The tie beam 13 is a transversely arranged rectangular column, and the tie beam 13 is arranged between the two support columns 11. Two tie beams 13 are arranged at intervals along the height direction of the support columns 11.

[0034] The pillars 11, cap beams 12 and tie beams 13 are all formed by casting steel cages and concrete. Specifically, before casting the pillars 11, a bearing platform is first cast at a predetermined low point (not shown in the figure), and then the steel cage of the pillars 11 is placed on the bearing platform to cast the pillars 11. Then, the steel cage of the tie beam 13 is placed between the two pillars 11, and the tie beam 13 is cast. Finally, the steel cage of the cap beam 12 is placed on the top of the two pillars 11, and the cap beam 12 is cast, thereby completing the casting of the entire frame column. According to the above method, the frame columns are cast at equal intervals along the layout direction of the trough body 2, thereby facilitating the placement of multiple sections of the trough body.

[0035] Reference Figure 1 The trough body 2 is an arc-shaped trough body, and both ends of the bottom of the trough body 2 are integrally formed with supporting feet 21. The bottom surface of the supporting feet 21 is lower than the lowest point of the trough body 2. Two supporting feet 21 are provided at one end of the trough body 2. The two supporting feet 21 are symmetrically arranged on both sides of the trough body 2 along the length direction of the trough body 2. There is a certain distance between the supporting feet 21 and the end surface of the trough body 2. In this embodiment, the distance between the supporting feet 21 and the trough body 2 is 80 mm. By setting the distance, it is convenient to install a sealing structure between adjacent trough bodies 2. The sealing structure is not shown in the figure.

[0036] Reference Figure 1 and Figure 2A positioning assembly 3 is provided on the cap beam 12, and the positioning assembly 3 includes two positioning members, and the two positioning members are symmetrically arranged along the length direction of the trough body 2. The positioning member includes a mounting portion 31 and a guide portion 32. The mounting portion 31 is plugged into the cap beam 12, and two adjacent mounting portions 31 are detachably connected, so that the two mounting portions 31 are clamped on the cap beam 12, and the guide portion 32 is arranged on the top of the mounting portion 31, so as to facilitate the positioning and guiding of the support leg 21.

[0037] Reference Figure 3 The mounting portion 31 includes a first mounting plate 311, a second mounting plate 312, a third mounting plate 313 and a fourth mounting plate 314, and all of them are rectangular plates. The first mounting plate 311 is vertically arranged, and there are two second mounting plates 312. The second mounting plate 312 is perpendicularly arranged to the first mounting plate 311, and the two second mounting plates 312 are respectively welded to the two ends of the first mounting plate 311. The third mounting plate 313 is perpendicularly arranged to the first mounting plate 311 and is parallel to the top surface of the cap beam 12. The third mounting plate 313 is welded to the top of the first mounting plate 311, and the third mounting plate 313 is located between the adjacent legs 21 on the two trough bodies 2. Refer to Figure 4 The fourth mounting plate 314 is vertically arranged on the first mounting plate 311 and is parallel to the bottom surface of the cap beam 12. The fourth mounting plate 314 is welded to the bottom of the first mounting plate 311. In this embodiment, in order to avoid the pillar 11, there are two fourth mounting plates 314, which are respectively located on both sides of the pillar 11.

[0038] When the mounting part 31 is plugged into the cap beam 12, the first mounting plate 311 abuts against the end wall of the cap beam 12, the second mounting plate 312 abuts against the side wall of the cap beam 12, the third mounting plate 313 abuts against the top surface of the cap beam 12, and the fourth mounting plate 314 abuts against the bottom surface of the cap beam 12, thereby realizing the plug-in of the mounting part 31 and the cap beam 12.

[0039] Reference Figure 2 and Figure 3 The second mounting plate 312 is welded with an ear plate 33 at one end away from the first mounting plate 311. After the two mounting parts 31 are plugged into the cap beam 12, the adjacent ear plates 33 of the two mounting parts 31 are fixed by bolts so that the two mounting parts 31 are fixed on the cap beam 12.

[0040] Reference Figure 3 and Figure 4The guide portion 32 includes a first guide plate 321, a second guide plate 322, and a third guide plate 323, and all of them are inclined plates, and the inclination direction is inclined from bottom to top in a direction away from the support leg 21. The bottom of the first guide plate 321 is welded to the top of the first mounting plate 311. Two second guide plates 322 are provided, and the bottoms of the two second guide plates 322 are respectively welded to the tops of the two second mounting plates 312. Two third guide plates 323 are provided, and the bottoms of the two third guide plates 323 are welded to both sides of the two third mounting plates 313.

[0041] When the guide portion 32 guides the support leg 21, the second guide plate 322 and the third guide plate 323 guide the support leg 21. Figure 2 The two first guide plates 321 on the two guide parts 32 guide the support legs 21 as shown in the front and rear directions. Figure 2 The left and right directions shown are used for positioning and guiding, so that the support feet 21 are positioned all around, thereby improving the accuracy of the tank body 2 during installation.

[0042] Reference Figure 3 and Figure 4 The two ends of the first guide plate 321 are respectively welded to the two second guide plates 322 , and the third guide plate 323 is welded to the first guide plate 321 to improve the anti-deformation ability of the guide portion 32 , thereby improving the strength of the positioning assembly 3 .
