[0030] The culvert coping is an important part of the culvert structure, which is located at the top of the culvert body and mainly serves to support the bridge structure. The culvert coping back wall is a small wall structure located at the rear end of the culvert coping, which is closely connected with the coping. There is usually a step surface between the coping and the back wall. The back wall plays a special connecting and supporting role, mainly for supporting the fill above the culvert and preventing the fill from sliding off the end of the culvert.

[0031] During the construction of the culvert coping, wooden formwork not lower than the height of the back wall of the culvert coping is used to pour the coping. After the concrete on the coping surface is poured and initially cured, a single-sided formwork is arranged on the coping surface, and the back wall concrete is poured between the single-sided formwork and the wooden formwork. However, the single-sided formwork is difficult to position in space, and it is prone to deformation with the pouring of the back wall concrete. This further leads to quality problems such as poor verticality of the poured and solidified back wall and uneven appearance of the coping.

[0032] To solve the above technical problems, the utility model provides a culvert coping formwork structure, which is applied to the construction of the culvert coping and supports the pouring of the back wall of the culvert coping. It improves the problem that the traditional single-sided formwork is prone to deformation during the pouring of the back wall concrete, improves the verticality of the poured and solidified back wall, and improves the problem of uneven appearance of the coping, thereby improving the quality of the coping.

[0033] The overall structure, working principle and technical effects of the culvert coping formwork structure provided by the utility model are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0034] Please refer to Figure 1 and Figure 2 The culvert coping formwork structure provided by the utility model comprises a wall body formwork 100 and an embedded formwork 200. The wall body formwork 100 is arranged on both sides of the body position, and the height of the wall body formwork 100 is higher than the height of the back wall. The wall body formwork 100 has a first pouring cavity 110, a second pouring cavity 120 and a third pouring cavity 130 connected therewith. The first pouring cavity 110, the second pouring cavity 120 and the third pouring cavity 130 are arranged in sequence from bottom to top. The first pouring cavity 110 is used for pouring the body concrete, the second pouring cavity 120 is used for pouring the coping concrete, and the third pouring cavity 130 is used for pouring the back wall concrete. The embedded formwork 200 is arranged in the third pouring cavity 130. The embedded formwork 200 has a support surface 210 and a bearing surface 220 which are parallel to each other. The support surface 210 is in contact with the inner wall of the wall body formwork 100, and the bearing surface 220 is located in the middle of the third pouring cavity 130. When the back wall is poured, the back wall is formed between the wall body formwork 100 and the bearing surface 220.

[0035] After the table body is poured in the first pouring cavity 110 and the table cap is poured and initial setting in the second pouring cavity 120, the embedded formwork 200 is installed in the third pouring cavity 130, and the back wall concrete is poured in the third pouring cavity 130. By arranging the embedded formwork 200, the construction process of separately positioning and installing the single-sided formwork in the traditional construction is not needed, and only the embedded formwork 200 is integrally installed in the third pouring cavity 130 and attached to the wall body formwork 100, so that the construction is convenient and fast. Meanwhile, the embedded formwork 200 is an integral structure, the deformation of the bearing surface 220 in the concrete pouring process is small, so that the perpendicularity of the solidified back wall is good, thereby improving the problem of linear straightness of the appearance of the table cap and improving the quality of the table cap.

[0036] In order to make the embedded formwork 200 closely attached to the table cap when installed, avoid the concrete entering the gap between the embedded formwork 200 and the table cap, affect the pouring quality of the back wall, and cause poor flatness of the table cap surface. Based on this, in some optional embodiments, please refer to Figure 1 and Figure 2 The embedded formwork 200 also has a leveling surface 230, which is connected to the support surface 210 and the bearing surface 220 and located at the bottom of the embedded formwork 200. The leveling surface 230 is in a horizontal state and flush with the top surface of the second pouring cavity 120. In actual construction, after the table cap is initial setting, the embedded formwork 200 is installed on the table cap, at this time the leveling surface 230 is attached to the table cap surface, on the one hand, it plays a positioning role for the embedded formwork 200, on the other hand, it avoids the back wall concrete entering between the leveling surface 230 and the table cap surface, and at the same time, the leveling surface 230 also has the function of providing support for the support surface 210 and the bearing surface 220.

[0037] Please refer to Figure 2 Further, the embedded formwork 200 also has a connecting surface 240, which is arranged between the support surface 210 and the bearing surface 220, and is used to support the support surface 210 and the bearing surface 220.

[0038] In the construction process of the back wall, generally after the table cap is initial setting, the pouring of the back wall is carried out. The waiting for the initial setting of the table cap surface for a long time leads to low efficiency of the table cap construction process and long construction period of the table cap.

[0039] Based on this, in other optional embodiments, please refer to Figure 1 and Figure 2The culvert abutment formwork structure further comprises a fixing assembly 300 connected with the embedded formwork 200 and used for fixing the embedded formwork 200. Thus, in the abutment pouring construction process, the embedded formwork 200 is fixed to the position of the third pouring cavity 130 abutting against the wall formwork 100 through the fixing assembly 300, and then the second pouring cavity 120 and the third pouring cavity 130 are poured, so as to realize the integrated pouring forming of the abutment and the back wall. While improving the connection strength of the abutment and the back wall, the construction period can be significantly shortened, and the construction efficiency is improved.

[0040] Please refer to Figure 1 and Figure 2 The fixing assembly 300 comprises a connecting rod 310, a reinforcing rod 320 and a connecting piece 330. The connecting rod 310 is connected to the embedded formwork 200 in the vertical direction. The reinforcing rod 320 is arranged in the length direction of the embedded formwork 200, and is fixed to an external structure, such as a scaffold. The connecting piece 330 is used for connecting the reinforcing rod 320 and the connecting rod 310. The reinforcing rod 320 is fixed to the external structure, the connecting rod 310 is connected and fixed to the reinforcing rod 320 through the connecting piece, and the connecting rod 310 is fixed to the embedded formwork 200, so as to realize the effect of fixing the embedded formwork 200 to the reinforcing rod 320 and fixing the embedded formwork 200.

[0041] Further, please refer to Figure 1 and Figure 3 The fixing assembly 300 is arranged in multiple numbers along the length direction of the embedded formwork 200 on the embedded formwork 200. The reinforcing rod 320 is connected with multiple connecting rods 310, that is, multiple connecting rods 310 are connected to the same reinforcing rod 320. The multiple connecting rods 310 make the fixing effect of the embedded formwork 200 good, and the embedded formwork 200 is uniformly stressed, so as to increase the structural stability.

[0042] Further, in the embodiment, the connecting rod 310 comprises a tensioning screw rod, one end of the tensioning screw rod is connected to the embedded formwork 200, and the other end of the tensioning screw rod extends vertically upward away from the embedded formwork 200. The connecting piece 330 comprises a butterfly clamp, the butterfly clamp is threadedly sleeved on the tensioning screw rod, and the position of the reinforcing rod 320 on the tensioning screw rod is adjusted by adjusting the position of the butterfly clamp on the tensioning screw rod, so as to fix the reinforcing rod 320.

[0043] Please refer to Figure 1 and Figure 2 In the embodiment, the embedded formwork 200 is rectangular in cross section and is hollow. The rectangular structure of the embedded formwork 200 is convenient for production and manufacturing. The embedded formwork 200 is made of light material, and is hollow, so as to reduce the overall weight of the embedded formwork 200, and facilitate the installation, carrying and transportation of the embedded formwork 200.

[0044] In summary, the specific implementation principle of the culvert abutment formwork structure is: by setting the embedded formwork 200, without the construction process of separately positioning and installing the single-sided formwork in the traditional construction, only the embedded formwork 200 is integrally installed into the third pouring cavity 130 and adhered to the wall body formwork 100, so that the construction is convenient and fast; meanwhile, the embedded formwork 200 is a whole structure, the deformation of the bearing surface 220 in the concrete pouring process is small, so that the perpendicularity of the solidified back wall is good, thereby improving the problem of linear straightness of the abutment appearance, and improving the quality of the abutment.

[0045] The above is only a specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
