Abstract
The invention discloses a falling-preventing safety inspection shaft wood frame which is characterized by being composed of an inspection shaft wood cover (1) and a wood frame support pillar (2). The falling-preventing safety inspection shaft wood frame is easy to manufacture and convenient to place, when an inspection shaft cover is lost unexpectedly, the falling-preventing safety inspection shaft wood frame can effectively prevent pedestrians and children from falling into the inspection shaft, simultaneously when the inspection shaft opening without the inspection shaft cover is submerged in flood, the inspection shaft wood cover (1) can float on the water due to buoyancy of wood so as to prompt pedestrians the danger of the inspection shaft opening, the long wood frame support pillar (2) can be clamped in the inspection frame, the flood cannot wash away the whole wood frame, and the effect of well safety protection can be achieved. The falling-preventing safety inspection shaft wood frame is simple in structure, can be produced in scale mode, and can eliminate the danger that people fall into the inspection shaft when the frame is placed in the inspection shaft.
Description
Technical field
The invention belongs to the technical field of Seat for manhole cover, especially a kind of fall arrest manhole yoke.
Background technology
The inspection shaft of urban road comprises that " rain, sewage, communication, tap water, natural gas, electric power, chemical industry etc. pipeline inspection shaft is the hole that make things convenient for engineering staff come in and go out of shielding for safeguarding that underground utilities are reserved at present.Use in the city and to manage the department of pipeline inspection shaft numerous, the quantity of pipeline inspection shaft is very big.In Guangzhou City 120,000 pipeline inspection shafts are just arranged, belong to 18 accountability unit such as water utilities, electric power, communication, combustion gas.On densely populated avenue, inspection shaft mismanagement and the security incident that causes take place at any time, use the safety design of inspection shaft and safeguard procedures to remedy very necessity of managerial deficiency.But the design specifications of the urban road pipeline inspection shaft in the Shanghai City that industrial technology is leading does not provide the necessary security setting yet now.As above " the separate type Seat for manhole cover " of Haiti side's design standard on the closing in member of inspection shaft pit shaft, overlapping the pedestal basis, is Cover of inspection well and cast iron seat with the pavement of road design elevation at pedestal, central without any the safety precaution design.When the unexpected disappearance of Cover of inspection well, inspection shaft is as the tiger that eats the people.Changsha suddenly rained cats and dogs and caused road ponding more than 9 evening on March 22nd, 2013.Be coated with house towards a vast expanse of water, helvolus road, 21 years old girl Yang Lijun falls into sewer accidentally, is swept away by torrent immediately, and is missing.Do not salvaged yet to this girl on the 25th, do not know whether one is dead or alive.The sewer mouth well lid that meets accident may be washed away by too much too urgent rainwater, breeds disaster, and such report is of common occurrence, and walking reaches by bike because do not note meeting the injured people of the inspection shaft of no well lid just more.How to transform the inspection shaft of existing One's name is legion in the city, design has the inspection shaft facility of safe precaution measure, guarantees that pedestrains safety is necessary.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, develop a kind of fall arrest manhole yoke that has safe precaution measure
Technical solution of the present invention is as follows:
1, a kind of fall arrest manhole yoke is characterized in that, as shown in the figure, fall arrest manhole yoke is made up of inspection shaft plank lid 1, yoke support column 2.
2, inspection shaft plank lid 1 is the plank of a circle, and its diameter is more smaller than inspection shaft diameter, puts into easily and takes out, and is unlikely to again too to become flexible; Arrange the aperture that drills on the circular plank, make things convenient for flowing of water.
3, yoke support column 2 and inspection shaft plank lid 1 firmly is connected, and the length of yoke support column 2 determines with the degree of depth of inspection shaft, when yoke is put inspection shaft into, should be able to guarantee inspection shaft plank lid 1 below the inspection shaft lid and press close to inspection shaft to cover.
4, the timber of fall arrest manhole yoke uses preservative treatment, can soak without putrefaction for a long time in water.
Fall arrest manhole yoke is simple in structure, lay conveniently, when inspection shaft lid accident is lost, can prevent that pedestrian and child from falling in the inspection shaft, when flood inundation on tracks did not have the inspection shaft mouth of inspection shaft lid, inspection shaft plank lid 1 was owing to the buoyancy of timber can float on the surface simultaneously, remind the pedestrian to note existence and the danger of inspection shaft mouth, long yoke support column 2 is stuck in the inspection shaft, and flood can't wash away whole yoke, plays safety precaution effect preferably.
Description of drawings:
Accompanying drawing is fall arrest manhole yoke outline drawing.
The specific embodiment:
Specific embodiments of the invention:
1, a kind of manhole cage is characterized in that, as shown in the figure, fall arrest manhole yoke is made up of inspection shaft plank lid 1, yoke support column 2.
2, inspection shaft plank lid 1 is the plank of a circle, and its diameter is more smaller than inspection shaft diameter, puts inspection shaft and taking-up easily into, is unlikely to again too to become flexible; Arrange the aperture that drills on the circular plank, make things convenient for flowing of water.
3, yoke support column 2 and inspection shaft plank lid 1 firmly is connected, and the length of yoke support column 2 determines with the degree of depth of inspection shaft, when yoke is put inspection shaft into, should be able to guarantee inspection shaft plank lid 1 below the inspection shaft lid and press close to inspection shaft to cover.
4, the timber of fall arrest manhole yoke uses preservative treatment, can soak without putrefaction for a long time in water.
Claims (4)
