Abstract
The utility model discloses a wall-protecting mold board for artificially excavating an electric pole pit. The wall-protecting mold board comprises a plurality of fan-shaped unit boards with large size on top and small size at bottom, wherein the plurality of the fan-shaped unit boards are embedded and encircled to form a circular truncated cone shape with large size on top and small size at bottom, a 7-shaped fitting groove is formed in the longitudinal edge of each fan-shaped unit board, the cross section of the matching surface of two adjacent fan-shaped unit boards are Z-shaped, and a handle is arranged on the large end surface of each fan-shaped unit board. According to the wall-protecting mold board for artificially excavating the electric pole pit, the plurality of the fan-shaped unit boards are embedded and encircled to form the circular truncated cone shape with large size on top and small size at bottom, the 7-shaped fitting groove is formed in the longitudinal edge of each fan-shaped unit board, and the handle is arranged on the large end surface of each fan-shaped unit board, therefore, the wall-protecting mold board can achieve a wall-protecting effect by the plurality of the fan-shaped unit boards when the quick-sand electric pole pit is artificially excavated, and the fan-shaped unit boards can be removed from the electric pole pit by the handles for repeated use after an electric pole is assembled.
Description
Technical field
The utility model relates to a kind of hand excavation's electric rod pit aid, particularly relates to a kind of hand excavation's electric rod pit dado template.
Background technology
At drift sand area hand excavation's electric rod pit, the aids such as the oil drum generally adopting at present, culvert pipe are constructed.Utilize oil drum excavation drift sand electric rod pit to carry out electric pole group and stand, exist oil drum to reclaim, cause the defects such as waste of material; Utilize culvert pipe excavation drift sand electric rod pit to carry out electric pole group and stand, culvert pipe weight is larger on the one hand, and construction is difficulty comparatively, and culvert pipe cost is high on the other hand, is unfavorable for reducing construction cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of economical and practical, practical and convenient hand excavation's electric rod pit dado template.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of hand excavation's electric rod pit dado template, comprise the sector element plate that polylith is up big and down small, described polylith sector element plate is chimeric surrounds up big and down small round platform tubular, the longitudinal edge of described sector element plate is provided with 7 font fit, the cross section of the fitting face between described adjacent two blocks of sector element plates is zigzag, on the large end end face of described sector element plate, is provided with handle.
As preferably, the quantity of described sector element plate is 3 to 5.
As preferably, described sector element plate and handle are made by metal material.
As preferably, described handle is welded on sector element plate.
A kind of hand excavation's electric rod pit of the utility model dado template, surround up big and down small round platform tubular by polylith sector element plate is chimeric, and at the longitudinal edge of sector element plate, 7 font fit are set, on the large end end face of sector element plate, handle is set, so both can reach by polylith sector element plate the retaining wall effect of hand excavation's drift sand electric rod pit, and can after group pole erecting, by handle, sector element plate be withdrawn to reuse from electric rod pit again.
A kind of hand excavation's electric rod pit of the utility model dado template, not only structure design is simple, uses easy to operately, and greatly reduces construction cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of hand excavation's electric rod pit of the utility model dado template.
Wherein, Reference numeral: 1 is sector element plate, 2 is handle.
The specific embodiment
Disclosed all features in this manual, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this manual, unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
As shown in Figure 1, a kind of hand excavation's electric rod pit of the utility model dado template, comprise the sector element plate 1 that polylith is up big and down small, described polylith sector element plate 1 is chimeric surrounds up big and down small round platform tubular, the longitudinal edge of described sector element plate 1 is provided with 7 font fit, the cross section of the fitting face that described adjacent two blocks of sector element plates are 1 is zigzag, so, by 7 font fit on two sector element plate 1 limits, realize chimeric, on the large end end face of described sector element plate 1, be provided with handle 2.
As shown in Figure 1, in a kind of hand excavation's electric rod pit of the utility model dado template, consider processing and manufacturing and stability in use requirement, the quantity of sector element plate 1 is designed to 3 to 5, is designed to 3 here.Sector element plate 1 and handle 2 are made by metal material, have both guaranteed mechanical property, reusable again.For the ease of manufacturing, handle 2 can be welded on sector element plate 1.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
