Abstract
The invention discloses an elastic walling crib. The elastic walling crib comprises an inner walling crib and an outer walling crib which is arranged on an inspection well, wherein the outer walling crib is of a Z-shaped structure with a vertical barb; an annular groove is formed in the inner wall of the inner walling crib; the inner walling crib is clamped in the outer walling crib through the annular groove; a disc spring is directly arranged at the opening of the annular groove of the inner walling crib and on the vertical barb of the outer walling crib; a slot is formed between the inner walling crib and the outer walling crib. Sedimentation of the walling cribs can be effectively prevented by adopting the elastic walling crib.
Description
Technical field
The present invention relates to the category of well hole ancillary service, specifically a kind of elasticity walling crib.
Background technology
Current, along with development and the road reformation in city, being arranged on ground communication, power cable etc. in a large number all needs to move on to underground, re-starts and lays.Conveniently these facilities safeguarded in the future and change.So build a large amount of inspection shafts to meet engineering maintenance in the future and the needs of examine and replace with regard to needing.The appearance of these inspection shafts, provides great convenience really to maintenance in the future and examine and replace.But these inspection shafts are while providing convenience to work, also some troubles are brought, after motor vehicle or pedestrian roll repeatedly, well lid in walling crib easily sinks from centre or breaks, the lighter cause motor vehicle advance middle appearance shake, also can cause the damage of motor vehicle under serious conditions, but also large hot-tempered sound can be produced, affect the normal life of people.What is more, when pedestrian is broken suddenly in the process of walking, pedestrian dropped into inspection shaft, causes casualties, and therefore, elasticity walling crib just seems particularly necessary.
Summary of the invention
The present invention aims to provide a kind of elasticity walling crib, to solve the problem.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of elasticity walling crib, is characterized in that: comprise interior walling crib, the outer walling crib be arranged on inspection shaft; Described outer walling crib is the Z-type structure with vertical barb; Described interior walling crib inwall has annular groove, and interior walling crib is stuck in outer walling crib by annular groove; Disc spring is provided with between the annular groove notch of described interior walling crib and the vertical barb of outer walling crib; Gap is left between described interior walling crib and outer walling crib.
Further, described interior walling crib upper end is connected with well lid.
Beneficial effect of the present invention is: the design of inside and outside walling crib, well lid is arranged in interior walling crib, and disc spring is provided with between inside and outside walling crib, disc spring can not affect the use of inspection shaft, loaded vehicle is through out-of-date, the pressure ratio that well lid is subject to is larger, disc spring can be compressed downward, well lid also has certain displacement downwards along with the compression of disc spring, when vehicle is fast through later, well lid resets under the effect of disc spring, and hand over light pedestrian or vehicle through out-of-date, its pressure be subject to is less, displacement is also little, its effect is also not obvious, so, effectively prevent the well lid effect of being directly under pressure and produce deformation, play the effect preventing well lid sedimentation.
Accompanying drawing explanation
Fig. 1 is elasticity walling crib structural representation provided by the invention.
Mark in figure: 1 be interior walling crib, 2 be outer walling crib, 3 be annular groove, 4 for disc spring.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of elasticity walling crib, comprises interior walling crib 1, the outer walling crib 2 be arranged on inspection shaft; Described outer walling crib is the Z-type structure with vertical barb; Described interior walling crib 1 inwall has annular groove 3, and interior walling crib 1 is stuck in outer walling crib 2 by annular groove; Disc spring 4 is provided with between annular groove 3 notch of described interior walling crib 1 and the vertical barb of outer walling crib; Gap is left between described interior walling crib and outer walling crib.Described interior walling crib upper end is connected with well lid.
The design of inside and outside walling crib, well lid is arranged in interior walling crib 1, and disc spring 4 is provided with between inside and outside walling crib, disc spring 4 can not affect the use of inspection shaft, loaded vehicle is through out-of-date, the pressure ratio that well lid is subject to is larger, disc spring 4 can be compressed downward, well lid also has certain displacement downwards along with the compression of disc spring 4, when vehicle is fast through later, well lid resets under the effect of disc spring 4, and hand over light pedestrian or vehicle through out-of-date, its pressure be subject to is less, displacement is also little, its effect is also not obvious, so, effectively prevent the well lid effect of being directly under pressure and produce deformation, play the effect preventing well lid sedimentation.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.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.
Claims (2)
