At present, there is a general problem of excessive process handover error between the sound barrier structure project and the civil engineering foundation project in the existing reserved foundations of urban rail transit sound barriers, resulting in the misaligned installation of the structural columns of the sound barrier, and then the roof structural beam cannot be installed or is forced to be installed, affecting the overall structural stability, resulting in reduced construction efficiency, slow construction progress, and a large number of non-standard parts in factory processing production, with complex processing.

[0010] (III) Beneficial effects
[0011] Compared with the prior art, the present utility model provides a column installation cushion beam base suitable for non-standard spacing or misaligned foundations of sound barriers, having the following beneficial effects:
[0012] By providing the column installation cushion beam base, the problem of misalignment deviation of the embedded bolts of the sound barrier structural column foundation pre-embedded part can be solved. Compared with the prior art improvement measures, it is not only applicable to the small-size deviation misalignment problem left by the civil engineering foundation pre-embedding, but also perfectly solves the large-size deviation problem.
[0013] By providing the column installation cushion beam base, the problems of time-consuming, labor-consuming and material-consuming of factory production of non-standard parts are greatly avoided. It replaces the cumbersome processing procedures caused by the eccentric welding of the sound barrier structural column and the bottom plate. And during the factory processing, various processes are produced according to standard parts, greatly improving the factory standardization production level and production efficiency.
[0014] By providing the column installation cushion beam base, great convenience is provided for the project construction and installation. In the past, due to the misalignment deviation problem left by the civil engineering foundation, most of the production of the sound barrier structural column and the sound barrier screen body was non-standard parts, which made the on-site installation very difficult. The data screening of the materials supplied to the construction site was numerous and easy to make mistakes, resulting in on-site material installation errors, rework, modification, unqualified quality, etc. By using the column installation cushion beam base provided in this application, the sound barrier structure above the base can be basically all standard parts, saving the on-site construction labor, machinery and schedule costs.
[0015] In addition, such a column installation cushion beam base is not only applicable to the installation of sound barriers on newly built lines, but also more applicable to the renovation and installation projects of sound barriers on existing lines. It is not only applicable to vertical sound barriers, but also applicable to fully and semi-closed sound barriers and other structural forms of sound barrier projects. Description of the drawings

Detailed implementation manners
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Refer to Figure 1 , and the problems existing in the currently reserved foundation of the sound barrier on the existing rail transit lines are marked by the cloud line in the figure: that is, there are problems of inconsistent axis deviation and dislocation on the reserved foundations on both sides of the track, where the dislocation dimensions such as L1, L2... Ln are of different sizes and various types. Specifically, it can be divided into two categories:
[0024] 1. The small deviation range is mostly in the range of 5 - 50 mm;
[0025] 2. The large deviation range is mostly in the range of 50 - 300 mm.
[0026] Regarding the dislocation dimensions such as L1, L2... Ln mentioned above, the current processing and installation technologies can only solve the problems in the small deviation range: that is, analyze, study, and adjust the small size errors that occur, and eliminate the errors during the prefabrication process in the factory. Refer to Figure 2, the method of eliminating errors during the prefabrication process in the factory is shown in the figure. By classifying and summarizing the smaller error data, a column grid layout plan that is convenient for factory prefabrication and conforms to the actual on-site situation is drawn. The requirement of installing the structural columns with the same longitudinal and transverse axes is achieved by slightly adjusting the relative positions of the steel columns and the column base plates and performing eccentric welding. In this way, although the method of slightly adjusting the relative positions of the structural columns and the column base plates and performing eccentric welding can solve the problem of small deviation misalignment of the reserved foundation of the sound barrier, this technical improvement measure increases the complexity of part assembly and dimension adjustment in the factory workshop. At the same time, this process requires production workshop managers and operators to have a certain ability to sort out professional dimension data, increasing the labor cost in the production process. Moreover, compared with the general production process of structural columns, this non-standard production process and technical improvement measure increase the processes of dimension marking adjustment, matching and assembly inspection, increasing the production man-hour cost and affecting the production progress. However, the construction site conditions of rail transit sound barriers are often very harsh, and their operation space, existing structures, and water and electricity facilities will all affect the accuracy of civil engineering foundation construction, resulting in different center distances of the embedded bolts of adjacent civil engineering foundations and excessive deviations, that is, the deviation ranges of L1, L2, L3... are 50 - 300 mm. This problem of excessive errors cannot be solved by civil engineering measures or the method of eccentric welding of structural columns.
[0027] To improve the existing technology, refer to Figures 3 to 5, this application proposes a structural column installation cushion beam base suitable for non-standard spacings or misaligned foundations of sound barriers. The top and bottom of the cushion beam base 10 are both formed as supports 11, and the middle of the cushion beam base 10 is formed as a support stiffener 12 fixedly connected to the two supports 11 respectively. A number of bottom reserved holes 14 matching the sound barrier foundation crown beam 20 are formed at the bottom of the cushion beam base 10, and a number of top reserved holes 13 matching the sound barrier structural column 30 are formed at the top of the cushion beam base 10. Moreover, the top reserved holes 13 are formed on the support 11 above the support stiffener 12, and the bottom reserved holes 14 are formed on the support 11 below the support stiffener 12. During installation or renovation, multiple cushion beam bases 10 can be distributed on opposite sides of the track, and each bottom of each cushion beam base 10 is fixedly connected to a sound barrier foundation crown beam 20, and each top of each cushion beam base 10 is fixedly connected to a sound barrier structural column 30. When the cushion beam base 10 is processed, the bottom reserved holes 14 can be opened in advance according to the non-fixed size spacing M between the embedded bolts 22 in every two adjacent sound barrier foundation crown beams 20 on the same side obtained by measurement, that is, the actual spacing between adjacent embedded bolts 22 is measured and recorded before construction, and the processing drawings are fed back to the prefabrication workshop for prefabrication of the cushion beam base 10 and opening of the bottom reserved holes 14. In addition, the spacing between the top reserved holes 13 on two adjacent cushion beam bases 10 is arranged and opened in advance as N, so that after the cushion beam bases 10 are installed, the spacing between the sound barrier structural columns 30 installed on every two cushion beam bases 10 is fixed as N.
[0028] A sound barrier foundation embedded part 21 is formed at the top of the sound barrier foundation crown beam 20, and a number of embedded bolts 22 passing through above the sound barrier foundation embedded part 21 are fixedly connected to the sound barrier foundation embedded part 21. When the cushion beam base 10 is installed, the upper end of the embedded bolt 22 passes through the bottom reserved hole 14 above it and is connected with a nut, thereby fixing the cushion beam base 10 on the sound barrier foundation embedded part 21.
[0029] A structural column bottom plate 31 is formed at the bottom of the sound barrier structural column 30, and a structural column stiffener 32 is formed at the bottom of the outer wall of the sound barrier structural column 30. The bottom of the structural column stiffener 32 is fixedly connected to the structural column bottom plate 31, and the entire sound barrier structural column 30 can be prefabricated with the same size.
[0030] When the sound barrier structural column 30 is installed, a plurality of fixing bolts 40 are arranged above the structural column bottom plate 31. The lower end of the fixing bolt 40 penetrates through the structural column bottom plate 31 and the top reserved hole 13 below it and is connected with a nut, thereby fixing the sound barrier structural column 30 above the cushion beam base 10.
[0031] In this embodiment, the cushion beam base 10 can be processed and manufactured using section steel. The specifications, models, and materials can be specifically designed and stability-checked according to the project characteristics, and the segmented length can be determined according to the actual requirements of the project. The sizes and quantities of the reserved holes at the top and bottom of the cushion beam base 10 need to be determined through design and checking and adjusted. Among them, the spacing N of the top reserved holes 13 affects the installation spacing of the sound barrier structure columns, and generally, a standard spacing of 2 m is used for layout. The spacing M of the bottom reserved holes 14 needs to be measured and determined according to the spacing of the embedded bolts of the existing foundation at the project site. The spacing of the support stiffeners 12 in the cushion beam base 10 can be determined according to the spacing of the structure columns, and is generally determined to be 1 / 3 of the structure column spacing.
[0032] Among all the solutions mentioned above, for the connection between two components, welding, connection with bolts and nuts, connection with bolts or screws, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated here one by one. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
