Abstract
The utility model discloses an it advances structure to contain notched box culvert top. Wherein: turn right from a left side and link to each other with first box culvert knee wall's one end, second box culvert knee wall's one end in proper order in one side of box culvert roof, the remaining one end of first box culvert knee wall all is provided with an arc iron sheet respectively with the remaining one end of second box culvert knee wall, first box culvert knee wall be equipped with the one end of arc iron sheet, one end that second box culvert knee wall was equipped with the arc iron sheet respectively with first recess, second recess sliding connection. Need filling talcum or other some media of reducing friction between box culvert and the slide, but after the filling medium, influencing the plane degree of slide easily, influence the propulsion of box culvert, the propulsion of box culvert is usually because the deviation appears removing in the skewness of the thrust of jack in addition, precision that the influence was under construction. The utility model has the advantages of: the great reduction of in -process frictional force that the box culvert advances on the top to make more simple and convenient of work progress, reduced the time that the construction consumes.
Description
Technical field
This utility model relates to a kind of box culvert advancing structure, particularly relates to a kind of containing reeded box culvert advancing structure.
Background technology
In the box culvert construct that some are small-sized, need between box culvert and slide plate to fill Talcum or the medium of other some minimizing frictions, but after filled media, easily affect the flatness of slide plate, affect the propelling of box culvert, in addition the propelling of box culvert is usually because movement deviation, the precision of impact construction occurs in the skewness of the thrust of jack.
Summary of the invention
Task to be solved in the utility model is to provide a kind of containing reeded box culvert advancing structure so that reach to reduce the purpose of frictional force during box culvert advancing.
In order to solve the problems referred to above, this utility model is achieved through the following technical solutions:
Containing reeded box culvert advancing structure, including box culvert top board, the first box culvert knee wall, the second box culvert knee wall, arc iron sheet, the first groove, the second groove, arc iron plate, slide plate；Wherein: the side of box culvert top board is connected with one end, one end of the second box culvert knee wall of the first box culvert knee wall the most successively；First remaining one end of box culvert knee wall and second remaining one end of box culvert knee wall are all respectively arranged with one block of arc iron sheet；The first groove, the second groove it is disposed with from left to right on slide plate；One piece of arc iron plate all it is respectively arranged with on the inwall of the first groove and the second groove；First box culvert knee wall is provided with one end of arc iron sheet, the second box culvert knee wall is provided with one end of arc iron sheet and is slidably connected with the first groove, the second groove respectively.
The utility model has the advantage of: by reducing the structure of box culvert on the premise of not affecting box culvert quality, decrease the use of construction material, groove is set, with iron plate, iron sheet, box culvert frictional force during jacking is greatly reduced, and make work progress the easiest, decrease the time spent by construction.

Reference: box culvert top board the 1, first box culvert knee wall the 2, second box culvert knee wall 3, arc iron sheet the 4, first groove the 5, second groove 6, arc iron plate 7, slide plate 8.
Detailed description of the invention
Embodiment, containing reeded box culvert advancing structure, including box culvert top board the 1, first box culvert knee wall the 2, second box culvert knee wall 3, arc iron sheet the 4, first groove the 5, second groove 6, arc iron plate 7, slide plate 8；Wherein: the side of box culvert top board 1 is connected with one end, one end of the second box culvert knee wall 3 of the first box culvert knee wall 2 the most successively；First remaining one end of box culvert knee wall 2 and second remaining one end of box culvert knee wall 3 are all respectively arranged with one block of arc iron sheet 4；First groove the 5, second groove 6 it is disposed with from left to right on slide plate 8；One piece of arc iron plate 7 all it is respectively arranged with on the inwall of the first groove 5 and the second groove 6；First box culvert knee wall 2 is provided with one end of arc iron sheet 4, the second box culvert knee wall 3 is provided with one end of arc iron sheet 4 and is slidably connected with first groove the 5, second groove 6 respectively.
Operation principle: owing to this box culvert advancing structure is mainly used in the little small bridge of stress and constructing tunnel, therefore original box culvert structure is being simplified in the case of calculating by measurement, the weight making box culvert is mitigated, first box culvert knee wall the 2, second box culvert knee wall 3 is provided with arc iron sheet 4 simultaneously, and in first groove the 5, second groove 6, it is provided with arc iron plate 7, so make box culvert frictional force during jacking greatly reduce.
