Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] An embodiment of the present application provides a trolley template for a culvert, which can solve the technical problem in the related art that when the cross-sectional span of the culvert is large, the size of the trolley template also needs to be made larger, which is not conducive to the overall movement of the trolley template.

[0034] See also Figure 1 and Figure 2 As shown, a trolley template for a culvert provided in an embodiment of the present application may include: a track 1, the extension direction of the track 1 is the same as the extension direction of the culvert to be cast; at least two trolley bodies 2, at least two of the trolley bodies 2 are arranged at intervals, and the trolley bodies 2 are each installed with a moving component, and the moving component can slide along the track 1. It should be understood that the number of trolley bodies 2 is set corresponding to the number of tracks 1. In the present embodiment, two trolley bodies 2 are provided. In some other embodiments, the trolley bodies 2 may be three or more depending on the span of the cross section of the culvert; a transverse connecting component 3, the two ends of the transverse connecting component 3 are respectively connected to two adjacent trolley bodies 2, and the two trolley bodies 2 are connected by the transverse connecting component 3, which can enhance the stability of the trolley body 2 during the concrete pouring process.

[0035] In addition, the culvert trolley formwork can also include an inner formwork 4, which includes a top plate 41 and side plates 42 fixed on opposite sides of the top plate 41, the top plate 41 is supported on the top of the trolley body 2, and the side plates 42 are connected to the trolley body 2 through a support assembly 24. It should be understood that the inner formwork 4 can be connected only by the top plate 41 and the side plates 42, or, according to the actual casting condition of the culvert, an inclined plate can be sandwiched between the top plate 41 and the side plates 42. In the present embodiment, the inner formwork 4 includes a top plate 41, a side plate 42 and an inclined plate, and the inclined plate is sandwiched between the top plate 41 and the inclined plate; an adjusting support column 5, the adjusting support column 5 is located between two adjacent trolley bodies 2, and one end of the adjusting support column 5 is supported on the top plate 41, and the other end is used to be installed on the guide wall 91. The adjusting support column 5 can be adjusted to facilitate its own movement, and can also enhance the stability of the trolley formwork during the casting process of the culvert. The trolley formwork is also the culvert trolley formwork. The embodiment of the present application sets at least two trolley bodies 2 in the trolley formwork for the culvert, so that when pouring the culvert with a large span cross-section, the trolley body 2 can be installed before being placed on the guide wall 91. Of course, a larger trolley can also be assembled before being placed in the culvert. However, compared with a larger trolley, the present embodiment uses multiple trolley bodies 2 in the trolley formwork, which is easier to hoist and has stronger safety. The trolley bodies 2 are respectively installed on the corresponding rails 1 and then connected by the transverse connecting components 3, which improves the assembly efficiency. In addition, multiple trolley bodies 2 are coordinated, and each trolley body 2 is equipped with a moving component. When the trolley formwork for the culvert needs to be transported, each moving component can only bear the mass of one trolley body, which can accelerate the transportation speed of the trolley body 2 while also facilitating the staff to control the pushing direction. In the direction, the displacement of the trolley body 2 during movement is reduced, and the overall movement of the trolley formwork for the culvert is more convenient. The transverse connection component 3 can be always connected to two adjacent trolley bodies 2, so that multiple trolley bodies 2 can always move in a flush manner during transportation. Preferably, during transportation, the transverse connection component 3 is removed from at least one side of the trolley body 2 to facilitate the staff to push a trolley body 2 alone. After the trolley body 2 moves to the specified position, multiple trolley bodies 2 are positioned and connected to the transverse connection component 3, and the inner formwork 4 and the guide wall 91 are supported by adjusting the support column 5. This can make the inner formwork 4 have stronger stability during the subsequent pouring process, which solves the technical problem in the related technology that when the cross-sectional span of the culvert is large, the size of the trolley formwork also needs to be made larger, which is not conducive to the overall movement of the trolley formwork.

[0043] In some optional embodiments, the trolley template for the culvert may also include: a tension screw 8, the tension screw 8 is passed through the side plate 42, and the tension screw 8 extends toward the side away from the trolley body 2. In this embodiment, the trolley template has completed the construction of the guide wall 91 before being placed in the culvert. After the guide wall 91 is built, the trolley template is placed on the track 1 fixed on the guide wall 91. An outer template 10 may be provided at a portion of the outer periphery of the culvert to be constructed. Preferably, the outer template 10 is provided at the side wall 92 (outer web), and the tension screw 8 is passed through the outer template 10 and the inner template 4. The tension screw 8 can be set as a three-section tension screw 8, the middle section is set as a water-stop screw 81, which can be an M16 water-stop screw 81, and the two ends are double-headed screws 82, which can be M18 trapezoidal double-headed screws 82, see Figure 3 As shown, the water-stop screw 81 and the double-headed screw 82 are connected by a conical nut 83. This arrangement can effectively prevent water seepage during culvert pouring. Figure 1 As shown, preferably, there may be a situation where two culverts need to be cast in parallel, and there is a partition wall 93 (middle web) between the two culverts. A three-stage tension screw 8 is also installed at the partition wall 93. At this time, the tension screw 8 can be installed with a PVC casing outside, so that the tension screw 8 used at the partition wall 93 can be reused. The full-length tension screw rods are constructed by passing through casing.

[0044] Preferably, the support assembly 24 includes a cornea 241, and the cornea 241 is connected to the inner template 4. The support assembly 24 also includes a diagonal brace 242, one end of the diagonal brace 242 is hinged to the cornea 241, and the other end is hinged to the trolley body 2. The support assembly 24 is supported between the inner template 4 and the trolley body 2. Multiple support assemblies 24 can be arranged along the height direction of the trolley body 2. According to the position of the support assembly 24, the diagonal brace 242 can form an angle with the top surface of the guide wall 91, or be arranged parallel to the top surface of the guide wall 91. The diagonal brace 242 is hinged to the cornea 241 and the trolley body 2. When the trolley template needs to be transported, the angle of the diagonal brace 242 can be adjusted so that the support assembly 24 no longer supports the inner template 4, thereby facilitating the separation of the cornea 241 and the diagonal brace 242 from the inner template 4.

[0045] In some optional embodiments, the pouring height of the guide wall 91 is determined according to the actual design size of the culvert, and a base plate can be fixedly installed at the bottom of the guide wall 91.

After that, the length of the threaded column 22 extending into the pipe column 211 and the length of the adjusting pipe 53 extending into the support pipe 52 are adjusted so that each component can support the inner template 4. After that, the outer template 10 is installed. Place it on the outside of the guide wall 91, so that the water stop screw 81 is left in the middle of the guide wall 91, and then connect and install the two sets of double-headed screws 82 through the conical nut 83, and then pull the outer template 10 close to the outer wall of the guide wall 91, so that the assembly of the trolley template can be completed quickly. The maximum spacing of the pulling screw 8 in the horizontal and vertical directions is 600mm*600mm. The inner side of the culvert can be easily controlled by the inner template 4 under the support of the trolley template. The lifting of the top plate 41 can be carried out by hydraulic jacks, and then the secondary pouring is carried out to complete the pouring of the side wall 92 and the main wall 94 of the culvert. After the poured concrete solidifies, the trolley body 2 is moved to the next construction section by a winch or manpower, and the inner template is transferred to the next continuous construction section by the pulley 73 bracket. Preferably, the inner template 4 is a steel template. In this embodiment, the span of the culvert is 500mm. In order to shorten the time for demolding and improve the turnover efficiency of the trolley formwork, two trolley bodies 2 are used for construction, and an adjustable support column 5 that can be quickly removed is added in the middle for construction. When dismantling, the trolley body 2 can be moved out to the lower section for installation, and the adjustable support column 5 can be removed for turnover after the concrete reaches the demolding strength. The double-headed screw 82 in the partition wall 93 can be recycled for reuse. At the same time, two trolley bodies 2 are arranged at the bottom of the inner formwork 4. The large span of the inner formwork 4 is divided into two parts by an independent adjustable support column 5, thereby further improving the transportation efficiency of the trolley formwork and shortening the assembly time of the trolley formwork, which has a good practical effect.
