Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Fig. 1 shows and makes stand 100 according to the landform of ecological riverway model of the present invention.This making stand 100 comprises frame 50, it comprise at least two mutual parallel and be in the girder 1 of same elevation.This stand 100 also comprises the supporting leg 4 for liftably support girder 1.The quantity of supporting leg 4 is determined according to the length of girder 1, ensures that girder 1 can not bend.The crossbeam 2 be connected with many girders 1 sliding-contact formula is provided with above girder 1.Crossbeam 2 is mainly used in the narrower region that sectional board 5 length is less than the distance between adjacent girder 1.Wherein, all girders 1 and crossbeam 2 are equipped with scale, and object is the quick position facilitating sectional board 5.Easy understand, supporting leg 4 realizes the process of its lifting by adjustment bolt 12.
In this embodiment, above girder 1 and crossbeam 2, be equipped with longitudinal register groove 11, it is for holding dimensional scales part (not shown).This dimensional scales part is preferably tape measure.This structure also conveniently realizes the connection of locator 3 and girder 1 or crossbeam 2, as shown in Figure 1 and Figure 2.
As shown in Figure 2, this making stand 100 also comprises locator 3, and it comprises the connector 7 be connected with girder 1 matched.The second end 22 of this connector 7 is provided with the suspension groove 10 for engaging with the sidewall of locating slot 11, thus locator is suspended in frame.The first end 25 of this connector 7 is provided with hollow ring portion 24.The pivot 23 being located at installation end 21 place of U-shaped installing plate 9 is inserted into this hollow ring portion 24 and is formed hinged, and U-shaped installing plate 9 can be rotated around connector 7.Be provided with pointer 6 at the installation end 21 of U-shaped installing plate 9, this pointer 6 together can rotate with installing plate 9 with U-shaped.The inner chamber of U-shaped installing plate 9 is shown in Fig. 1 for installing sectional board 5().Sectional board 5 is fixed in the inner chamber of U-shaped installing plate 9 by the fixed wedge 13 filled between sectional board 5 and U-shaped installing plate 9.In order to strengthen the Stability Analysis of Structures of U-shaped installing plate 9, outside it, be such as welded with ribs 8.Conveniently in the location in elevation direction, outside U-shaped installing plate 9, be also provided with dimensional scales part (not shown).This dimensional scales part is such as tape measure, and it is arranged in the edge outside installing plate 9, and scale place and installing plate 9 coincident, thus convenient location sectional board elevation.Due to, this sectional board 5 is arranged in the inner chamber of U-shaped installing plate 9, can decrease the distortion of self, thus ensures the stability of sectional board 5 structure.
In this embodiment, as shown in Figure 1, the pointer 6 of locator 3 has two kinds to be distributed with two kinds of situations.A kind of situation is locator 3 when being connected to girder 1, and the sensing of pointer 6 is parallel with installing plate 9.Another kind of situation is locator 3 when being connected to crossbeam 2, and the sensing of pointer 6 is vertical with installing plate 9.The design of this spline structure is to ensure that pointer 6 points to scale place always.
According to the present invention, every block sectional board 5 is at least fixed by two locators 3, the section line then by regulating the axis of locator 3 on girder 1 or crossbeam 2 and angle position to determine sectional board.
Landform according to ecological riverway model of the present invention makes stand 100.Concrete steps in operation are as follows:
The first step, installation frame 50.First according to the test drawing of ecological riverway, in the lab, the river location of selected ecological model, according to axis, river course along selecting two main lines again.Selected main line is installed girder 1, and it is consistent for tentatively adjusting supporting leg 4 height by adjustment bolt 12, and then is finely tuned by level gauge, ensures be parallel to each other between these many girders 1 and be in same elevation.If experimental simulation river course is wider, the quantity of girder 1 can be increased in order to ensure the stability of sectional board 5.In addition, when sectional board 5 length to be installed is less than the distance between adjacent girder 1, needs crossbeam 2 to be connected with girder 1 sliding-contact formula, and then sectional board 5 is arranged on crossbeam 2, thus make up the defect that girder 1 can not locate shorter sectional board.
Second step, sectional board 5 is located.According to section line position, determine the position of sectional board 5 in frame 50 to be installed.Then the locator 3 being used for locating this sectional board 5 is arranged on different girders 1 respectively, then adjusts the position on locator 3 place girder 1 by pointer 6, the line of each locator 3 is overlapped with section line.The sectional board to be installed 5 completed marks the position of locator 3, is arranged on the inner chamber of locator 3, then adjust the elevation of sectional board 5 by the dimensional scales part outside U-shaped installing plate 9.After elevation is adjusted, between U-shaped installing plate 9 and sectional board to be installed 5, fill in fixed wedge 13, complete the three-dimensional localization in river model of sectional board.Easy understand, sectional board 5 be arranged on the operating procedure of crossbeam 2 and the above-mentioned step being arranged on girder 1 similar, belong to that the art personnel are readily appreciated that, no further details to be given herein.
Finally, with model sasnd, consolidation is filled and led up in the position of sectional board 5, uniform application forms landform.When after sectional board 5 fixation, remove this making stand 100, the landform completing this river model (ecological riverway model) makes.
Therefore, the landform of the ecological riverway model of the application of the invention makes stand 100, the three-dimensional localization quickly and accurately of sectional board can be realized, to the change of natural, ecological river topography greatly, section complicated situation has stronger compliance, environmental hydro science can be met, Ecological waterscape etc. are to river course flexibility and the multifarious demand of section, achieve bending, divide the branch of a river, shoal deep trouth replaces the making of the landform of the complex situations such as river course, save a large amount of manpower and special training is carried out to personnel, also improve stability and the positioning precision of sectional board structure simultaneously.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
