Abstract
Description
Technical Field
[0001] This utility model relates to the field of cross-river aqueduct construction technology, and in particular to a formwork installation and support device for cross-river aqueducts in sand and gravel strata. Background Technology
[0002] An aqueduct is a channel used to transport water across rivers, valleys, depressions, and roads. It is currently widely used for irrigation, flood control, and sediment removal. When constructing an aqueduct in gravelly soil, due to the presence and varying depths of water in this soil, piers are often required to support the aqueduct. The typical construction sequence is: trench excavation → pile head chiseling → pier reinforcement → pier formwork erection → scaffolding erection → upper tie beam bottom formwork erection → upper tie beam reinforcement installation → upper tie beam side formwork erection → upper pier formwork erection → pier and upper tie beam concrete pouring. During formwork installation, wooden formwork is typically used. However, due to the long length of the aqueduct, it is difficult to find suitable lengths of wooden planks for use as formwork; therefore, multiple planks are spliced together. This method inevitably results in gaps in the formwork. When pouring concrete, some of the concrete will seep out from these gaps, making the surface of the aqueduct uneven. In severe cases, it can even cause structural damage to the aqueduct, leading to water seepage and even breakage during long-term use. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a template installation and support device for a river crossing aqueduct in sandy and gravelly strata, which addresses the shortcomings of the prior art. The gaps between adjacent templates are filled with rubber, and the clamping mechanism and telescopic mechanism are combined to ensure the force between adjacent templates, so that the surface of the aqueduct is smooth after pouring.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a support device for installing a formwork for a river crossing in sand and gravel strata, including a support frame located at the bottom of the aqueduct formwork, a longitudinal support plate respectively provided on the left and right sides of the support frame, the support plate being connected to the support frame through a telescopic mechanism with adjustable length and limit, a longitudinal U-shaped rubber plate being provided on the top of the support plate, the U-shaped rubber plate corresponding to the end face section of the aqueduct formwork, and a clamping mechanism for clamping the aqueduct formwork being provided on the support frame.
[0005] Furthermore, the telescopic mechanism includes a first spring, with its two ends connected to the support frame and the support plate, respectively. An adjustable telescopic rod is fitted inside the first spring, with its two ends connected to the support frame and the support plate, respectively.
[0006] Furthermore, the surfaces of the two U-shaped rubber plates on opposite sides are each provided with a number of recesses, which are used for screws that fix the U-shaped rubber plates to pass through.
[0007] Furthermore, a rubber sheet is attached to a point on the edge of the recessed opening.
[0008] Furthermore, the clamping mechanism includes horizontal support rods respectively disposed on the front and rear sides of the support frame. Each horizontal support rod has a groove on its upper surface along its length direction. A slider is slidably connected to the groove. The slider is positioned on the groove by a limiting mechanism. A vertical support rod is connected to the slider. A clamping plate is disposed on the top of the vertical support rod.
[0009] Furthermore, the limiting mechanism includes a second spring and an elastic connecting band. The two ends of the second spring are respectively connected to the support frame and the vertical support rod, and the two ends of the elastic connecting band are respectively connected to the two clamping plates.
[0010] Furthermore, the clamping plate is detachably connected to the elastic connecting strip.
[0011] Furthermore, the top of the support frame is provided with a support pad for lining the bottom of the aqueduct template.
[0012] This utility model has the following advantages compared with the prior art:
[0013] This utility model provides a support device for the installation of formwork for a river crossing in sandy and gravelly strata. It uses U-shaped rubber plates corresponding to the cross-section of the aqueduct formwork end face to cover the end face of the formwork. During the splicing of the aqueduct formwork, two matching U-shaped rubber plates press against each other, filling the gaps between adjacent aqueduct formwork surfaces that need to contact with each other. Simultaneously, combined with a clamping mechanism for positioning the aqueduct formwork, a telescopic mechanism brings the U-shaped rubber plates and the end faces of the aqueduct formwork into place, ensuring no gaps between them. This guarantees stable filling of the gaps between adjacent aqueduct formwork, resulting in a smooth aqueduct surface after pouring, thus enhancing the safety of the aqueduct during long-term use and improving the aqueduct construction process.
[0014] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] like Figure 1-4 As shown, the present invention provides a support device for the installation of a cross-river aqueduct template in sandy and gravelly strata, including a support frame 1 located at the bottom of the aqueduct template 6. A longitudinal support plate 4 is respectively provided on the left and right sides of the support frame 1. The support plate 4 is connected to the support frame 1 through a telescopic mechanism with adjustable length and limit. A longitudinal U-shaped rubber plate 5 is provided on the top of the support plate 4. The U-shaped rubber plate 5 corresponds to the end face section of the aqueduct template 6. A clamping mechanism for clamping the aqueduct template 6 is also provided on the support frame 1.
[0022] In this utility model, the support frame 1 is used to provide support when building the aqueduct template 6. The aqueduct template 6 will be removed after pouring, thus obtaining an aqueduct.
[0023] This invention uses U-shaped rubber plates 5 corresponding to the cross-section of the aqueduct template 6 to cover the end face of the aqueduct template 6. When splicing the aqueduct template 6, the two matching U-shaped rubber plates 5 are pressed against each other, so that the surfaces of the two adjacent aqueduct templates 6 that need to contact are filled with rubber. At the same time, combined with the positioning of the aqueduct template 6 by the clamping mechanism, the telescopic mechanism fits the end face of the U-shaped rubber plate 5 and the aqueduct template 6 together, so that there are no gaps between the aqueduct template 6 and the U-shaped rubber plate 5. This ensures that the gaps between the two adjacent aqueduct templates 6 are stably filled, so that the surface of the aqueduct is smooth after pouring, thereby improving the safety of the aqueduct in long-term use and improving the construction process of the aqueduct.
[0024] To further optimize the telescopic mechanism of this utility model, a new embodiment is proposed. The telescopic mechanism includes a first spring 10, with its two ends connected to the support frame 1 and the support plate 4, respectively. An adjustable telescopic rod 3 is fitted inside the first spring 10, with its two ends connected to the support frame 1 and the support plate 4, respectively. The telescopic rod 3 ensures that the first spring 10 deforms only in a straight line during telescopic movement and does not bend in other directions.
[0025] Meanwhile, in order to make the gap between two adjacent aqueduct templates 6 more tightly filled, the two U-shaped rubber plates 5 on opposite sides of this invention are respectively provided with a number of recesses 11, which are used for screws that fix the U-shaped rubber plates 5 to pass through. A rubber sheet 12 is connected to a point on the edge of the opening of each recess 11.
[0026] The screw passes through the recess 11 to fix the U-shaped rubber plate 5 to the cross section of the aqueduct template 6. The screw head is located inside the recess 11. The rubber sheet 12 can close and fill the recess 11 with the screw, so that the surface of the U-shaped rubber plate 5 is flat.
[0027] In this invention, in order to fix the position of the aqueduct template 6 and prevent it from shifting during installation, a clamping mechanism is proposed. In this invention, the clamping mechanism includes horizontal support rods 2 respectively disposed on the front and rear sides of the support frame 1. Each horizontal support rod 2 has a groove 14 opened on its upper surface along its length direction. A slider 13 is slidably connected to the groove 14. The slider 13 is limited in position on the groove 14 by a limiting mechanism. A vertical support rod 7 is connected to the slider 13. A clamping plate 8 is provided on the top of the vertical support rod 7.
[0028] In this invention, clamping plates 8 clamp the aqueduct template 6, and their fixation is achieved by a limiting mechanism that reduces the distance between the two clamping plates 8, thus securing the aqueduct template 6 tightly. To further optimize the technical solution of this invention, the limiting mechanism includes a second spring 16 and an elastic connecting band 9. The two ends of the second spring 16 are respectively connected to the support frame 1 and the vertical support rod 7, and the two ends of the elastic connecting band 9 are respectively connected to the two clamping plates 8. The elastic connecting band 9 and the second spring 16 retract the clamping plates 8 towards the aqueduct template 6 from both vertical and horizontal directions, thus securing the aqueduct template 6 tightly by the clamping mechanism. As an optimization, for convenient and quick edge construction, the clamping plates 8 and the elastic connecting band 9 are detachably connected.
[0029] In addition, in this utility model, the top of the support frame 1 is provided with a support pad 15 for padding the bottom of the aqueduct template 6, thereby effectively protecting the bottom of the aqueduct template 6. The support pad 15 can be made of rubber.
[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
