[0023] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.

[0024] Example 1

[0025] Reference Figure 2 and Figure 3 The cover structure utilizing the existing terrain in the recessed area includes a supporting cover plate 4. The supporting cover plate 4 is fixedly installed on the existing slope 5 and the existing low retaining wall 6 on both sides parallel to the width direction of the drainage ditch 2. The supporting cover plate 4 is located below the newly constructed embankment 7. When widening the existing roadbed, if the embankment 7 needs to encroach on the existing drainage ditch 2, the supporting cover plate 4 is erected on the drainage ditch 2. The two sides of the supporting cover plate 4 are fixed on the existing slope 5 and the existing low retaining wall 6, respectively. Then the embankment 7 is constructed. If the supporting cover plate 4 is placed under the embankment 7, or embankment is carried out on one side of the supporting cover plate 4, the drainage ditch 2 of the existing project 1 is preserved, the construction cost is reduced, and the construction efficiency of the widening project is improved.

[0026] Reference Figure 2 and Figure 3 In this embodiment, the support cover plate 4 is arched, and the center of the support cover plate 4 faces the drainage ditch 2; the arched support cover plate 4 increases the load-bearing capacity of the support cover plate 4, thereby facilitating the construction of the filling project 7.

[0027] Reference Figure 2 and Figure 3 To facilitate the connection of adjacent support cover plates 4 and improve the overall stability and load-bearing capacity of the support cover plates 4, a connector 8 is provided at the end of the support cover plate 4 along the length direction of the drainage ditch 2. The connector 8 is used to connect adjacent support cover plates 4. In this embodiment, the connector 8 includes a first protruding insert 81 provided at the end of the support cover plate 4 and a first protruding slot 82 opened at the end of the adjacent support cover plate 4. The curvature of the first protruding insert 81 and the first protruding slot 82 is consistent with that of the support cover plate 4. The first protruding insert 81 is inserted into the first protruding slot 82 of the adjacent support cover plate 4. The first protruding insert 81 is located at both ends of the support cover plate 4, and the first protruding slot 82 is located at both ends of the adjacent support cover plate 4. The support cover plates 4 with the first protruding insert 81 and the first protruding slot 82 are arranged at intervals. When installing the support cover plate 4, the first protruding insert 81 is inserted into the adjacent first protruding slot 82, thereby connecting the adjacent support cover plates 4 into a whole. The operation is simple and convenient, and the construction efficiency is improved.

[0028] Reference Figure 2 and Figure 3In other embodiments of this application, the connector 8 can be replaced by a second protruding insert block disposed at the end of the support cover plate 4 and a second protruding slot opened on the support cover plate 4. The second protruding slot is located at the end opposite to the second protruding insert block. When the support cover plate 4 is installed, the second protruding insert block is inserted into the second protruding slot to complete the connection of the support cover plate 4. The operation is simple and convenient. Moreover, the support cover plate 4 of the above shape has the same specifications, which facilitates prefabrication and construction, thereby improving the prefabrication efficiency of the support cover plate 4.

[0029] The implementation principle of Example 1 is as follows:

[0030] When widening an existing roadbed, if the embankment project 7 needs to encroach on the existing drainage ditch 2, a support cover plate 4 is erected on the drainage ditch 2. The two sides of the support cover plate 4 are fixed to the existing slope 5 and the existing low retaining wall 6, respectively. Then, the support cover plate 4 is laid along the direction of the drainage ditch 2 so that the adjacent support cover plates 4 are interlocked. Then, the embankment project 7 is constructed. If the support cover plate 4 is placed under the embankment project 7, or if embankment is carried out on one side of the support cover plate 4, the existing drainage ditch 2 of the existing project 1 is preserved, the construction cost is reduced, and the construction efficiency of the widening project is improved.

[0031] Example 2

[0032] The difference between Example 2 and Example 1 is that, referring to... Figure 4 and Figure 5 The supporting cover plate 4 is Z-shaped. The supporting cover plate 4 includes an L-shaped first retaining wall 41 and a baffle 42 set on the first retaining wall 41. The horizontal plate of the first retaining wall 41 is fixedly set on the low retaining wall 6 and the vertical plate is used to block the filling of the new project. The baffle 42 is set on the vertical plate of the first retaining wall 41 and spans the drainage ditch 2 and is fixedly set on the existing slope 5. Furthermore, the baffle 42 extends into the existing slope 5.

[0033] When constructing drainage ditch 2, the horizontal plate of the first retaining wall 41 is fixed to the existing low retaining wall 6, and then the baffle 42 is installed on the first retaining wall 41. The free end of the baffle 42 is fixed in the existing slope 5, thereby completing the protection of drainage ditch 2. The operation is simple and convenient. Moreover, under the action of the first retaining wall 41, the end of the filling project 7 is blocked, reducing the possibility of landslide of the filling project 7.

[0034] Reference Figure 4 and Figure 5 To facilitate the installation and fixing of the baffle 42, an installation groove 9 is provided on the top surface of the vertical plate of the first retaining wall 41. One end of the baffle 42 is snapped into the installation groove 9, and the other end is fixedly set on the existing slope 5. When installing the baffle 42, the file is snapped into the installation groove 9 and the other end is inserted into the existing slope 5. The operation is simple and convenient.

[0035] Reference Figure 4 and Figure 5 To facilitate the collection of rainwater into the drainage ditch 2, baffles 42 are arranged at intervals on the vertical plate; rainwater enters the drainage ditch 2 through the gaps between adjacent baffles 42, reducing the possibility of landslides in the embankment project 7.

[0036] Reference Figure 4 and Figure 5 When the height of the fill project 7 is large, in order to facilitate the support of the fill project 7, the number of vertical support cover plates 4 is at least one. When the number is greater than one, the support cover plates 4 overlap vertically. It also includes fixing components for fixing the vertically overlapping support cover plates 4. The fixing components include insert bars fixed on the vertical plate of the first retaining wall 41 and insert holes opened at the bottom of the horizontal plate for insert bars to be inserted. The insert bars are set vertically. When supporting the fill project 7 with a large height, a suitable number of support cover plates 4 are selected and overlapped. The vertical support cover plates 4 are connected by insert bars. The operation is simple and convenient.

[0037] The principle of Example 2 is as follows:

[0038] When constructing drainage ditch 2, the horizontal plate of the first retaining wall 41 is fixed to the existing low retaining wall 6, and then the baffle 42 is installed on the first retaining wall 41. The free end of the baffle 42 is fixed in the existing slope 5, thereby completing the protection of drainage ditch 2. The operation is simple and convenient. Moreover, under the action of the first retaining wall 41, the end of the filling project 7 is blocked, reducing the possibility of landslide of the filling project 7.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
