[0002] An 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, precast concrete trough bodies are usually used for splicing to improve the construction efficiency and quality of the aqueduct. When producing precast concrete trough bodies, the trough body formwork is first built, and then concrete is poured into the trough body formwork to form the trough body structure.

[0003] The commonly used aqueduct body formwork structure includes a formwork frame and a grouting port. During the pouring process, concrete is continuously poured into the grouting port to fill the entire formwork frame. When the concrete is completely solidified, the formwork frame is removed to form a prefabricated aqueduct body.

[0004] Regarding the above-mentioned related technologies, when the aqueduct body is an arc-shaped body, during the concrete pouring process, some air will accumulate near the lowest point on the inner side of the arc-shaped body to form an air cavity, which makes it impossible for the concrete to completely fill the interior of the formwork frame, resulting in low casting quality of the body.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a prefabricated aqueduct body template structure that is convenient for grouting. Figure 1 The prefabricated aqueduct body template structure for grouting includes a template frame 1 and an exhaust assembly 2 arranged on the template frame 1. The template frame 1 includes an outer template 11, an inner template 12 and two end templates 13. The outer template 11 and the inner template 12 are both arc-shaped as a whole. The diameter of the inner template 12 is smaller than that of the outer template 11 and is concentrically arranged with the outer template 11. The ends of the outer template 11 and the inner template 12 are flush. The two end templates 13 are respectively located at the two ends of the outer template 11 and the inner template 12, and are fixedly connected to the outer template 11 and the inner template 12 by bolts. The outer template 11, the inner template 12 and the two end templates 13 form an arc-shaped casting cavity. The top of the inner template 12, that is, the lowest point of the inner template 12, is provided with a plurality of exhaust holes 121, and the plurality of exhaust holes 121 are arranged at equal intervals along the length direction of the inner template 12. The exhaust assembly 2 is arranged near the exhaust holes 121 of the inner template 12.

[0033] Reference Figure 1The template frame 1 also includes a support frame 15 and a reinforcement frame 14. The support frame 15 is square steel. The support frame 15 is welded to both sides and the top of the template frame 1, thereby reducing the possibility of deformation of the template frame 1 and improving the stability of the template frame 1. The support frame 15 is evenly spaced along the length direction of the template frame 1. In this embodiment, the length of the template frame 1 is 6m, and there are nine groups of support frames 15. The spacing between adjacent support frames 15 is 0.6m. The reinforcement frame 14 is arranged on the inner template 12. The reinforcement frame 14 includes vertical reinforcement ribs 141 and transverse reinforcement ribs 142. The vertical reinforcement ribs 141 are rectangular steel rods. The vertical reinforcement ribs 141 are welded to the inner template 12. The vertical reinforcement ribs 141 are evenly spaced along the circumferential direction of the inner template 12. The transverse reinforcement ribs 142 are arc-shaped steel rods concentrically arranged with the inner template 12. The transverse reinforcement ribs 142 are welded to multiple vertical reinforcement ribs 141. The transverse reinforcement ribs 142 are evenly spaced along the length direction of the inner template 12. The support frame 15 is provided to reinforce the peripheral side of the template frame 1, and the reinforcing frame 14 is provided to reinforce the inner side of the template frame 1, that is, the inner template 12, so as to improve the deformation resistance of the template frame 1 and improve the casting quality of the trough body.

[0034] Since the pouring cavity is in an arc shape as a whole, when concrete flows in the pouring cavity, during the process of concrete accumulating from the lowest point to the highest point of the pouring cavity, some air is retained in the pouring cavity near the exhaust hole 121, forming an air cavity, which makes it impossible for concrete to completely fill the pouring cavity, resulting in multiple depressions in the poured aqueduct body and low quality. In the embodiment of the present application, the exhaust hole 121 is provided, and the exhaust hole 121 is controlled to be opened or closed by the exhaust component 2, so that the air in the air cavity is discharged from the pouring cavity, so that the concrete can fill the pouring cavity as much as possible, thereby improving the quality of the trough body casting.

[0035] Specifically, refer to Figure 2 and Figure 3 The exhaust assembly 2 includes a mounting plate 21, a slide bar 22 and a locking piece 23, and the slide bar 22 and the locking piece 23 are both arranged on the mounting plate 21. The mounting plate 21 is a U-shaped plate, and the long side direction of the mounting plate 21 is consistent with the length direction of the inner template 12, and the mounting plate 21 is welded on the inner template 12 by inverted buckle. The slide bar 22 is a round bar, and the exhaust hole 121 is a circular hole. The diameter of the slide bar 22 is the same as that of the exhaust hole 121. The slide bar 22 is vertically arranged and passes through the mounting plate 21, and is vertically slidably connected with the mounting plate 21. The slide bar 22 moves between two states of being plugged into the exhaust hole 121 and being detached from the exhaust hole 121. When the slide bar 22 is plugged into the exhaust hole 121, the exhaust hole 121 is in a closed state, and when the slide bar 22 is detached from the exhaust hole 121, the exhaust hole 121 is in an open state. When the exhaust hole 121 is in a closed state, the locking member 23 can lock the slide bar 22 to prevent the concrete in the casting cavity from pushing the slide bar 22 out of the exhaust hole 121 .

[0036] Reference Figure 3 A plurality of slide bars 22 are provided along the length direction of the inner template 12. The number of slide bars 22 is the same as the number of exhaust holes 121, and one slide bar 22 corresponds to one exhaust hole 121. In order to facilitate simultaneous control of the plurality of slide bars 22, a connecting plate 24 is provided on the side of the slide bar 22 away from the inner template 12. The connecting plate 24 is a rectangular plate, and the connecting plate 24 is welded to the ends of the plurality of slide bars 22 away from the template frame 1.

[0037] Reference Figure 2 and Figure 3 A limit plate 25 is provided on the slide bar 22. When the slide bar 22 is plugged into the exhaust hole 121, the limit plate 25 abuts against the inner template 12 to prevent the slide bar 22 from passing through the exhaust hole 121 into the casting cavity and affecting the casting quality of the trough body.

[0038] Reference Figure 2 and Figure 3 The locking member 23 includes a locking screw 231 and a locking nut 232. The locking screw 231 is vertically arranged and one end is welded to the mounting plate 21, and the other end passes through the connecting plate 24 and is slidably connected to the connecting plate 24. Two groups of locking members 23 are symmetrically arranged along the width direction of the inner template 12, thereby improving the stability of locking the slide bar 22.

[0039] When pouring concrete into the pouring cavity, the operator slides the sliding rod 22 upwards through the connecting plate 24 to disengage the sliding rod 22 from the exhaust hole 121. The exhaust hole 121 is opened, and the air between the concrete and the formwork frame 1 is squeezed by the concrete and discharged from the pouring cavity through the exhaust hole 121. When the concrete is about to emerge from the exhaust hole 121, the operator releases the connecting plate 24 to connect the sliding rod 22 with the exhaust hole 121, and threadedly connects the locking nut 232 with the locking screw 231, so that the locking nut 232 is pressed against the connecting plate 24, and the limiting plate 25 is used to lock the sliding rod 22, thereby closing the exhaust hole 121.

[0040] Reference Figure 2 When the slide bar 22 is plugged into the exhaust hole 121, that is, when the limit plate 25 is pressed against the inner template 12, the slide bar 22 is flush with the side of the inner template 12 close to the outer template 11, so that the cast trough body is relatively flat at the exhaust hole 121, reducing the possibility that the exhaust hole 121 affects the casting quality of the trough body.

[0041] The implementation principle of the prefabricated aqueduct body formwork structure that is convenient for grouting in the embodiment of the present application is as follows: by setting a support frame 15 to reinforce the surrounding side of the formwork frame 1, and by setting a reinforcing frame 14 to reinforce the inner side of the formwork frame 1, the deformation resistance of the formwork frame 1 is improved; by setting an exhaust hole 121 and an exhaust component 2, the exhaust component 2 controls the exhaust hole 121 to open, so that the air accumulated in the casting cavity is discharged through the exhaust hole 121, thereby reducing the possibility of the existence of an air cavity in the casting cavity, thereby improving the casting quality of the trough body.

[0042] In this embodiment, a plurality of vibrators are fixed on the peripheral side of the outer formwork 11, which are not shown in the figure. When pouring concrete, the vibration waves generated by the vibrators are indirectly transmitted to the concrete in the pouring cavity through the outer formwork 11, thereby accelerating the concrete to fill the pouring cavity and promoting the air entrained in the concrete to be discharged from the concrete, thereby further improving the pouring quality of the concrete.
