Description
Technical field
The utility model relates to a kind of safety device of municipal manhole.
Background technology
Municipal administration manhole also claims people's well, common are cable manhole, communication manhole etc., and namely in order to overhaul, the facility of threading, can the vertical channel of servant every one section of excavation one; Along with the quickening of expanding economy, Urbanization Construction, greatly promoted infrastructure construction, newly-built community, road occur in a large number, as long as there is the place of the communal facilities such as municipal administration, communication, just need to arrange installation check well.Along with rolling up of manhole, it is frequently existing that the pedestrian caused because of manhole cover damage, heavy rain wash away, the reason such as theft causes manhole cover loss falls the personal safety accidents such as well.As can be seen here, along with the continuous increase of manhole, safety device supporting with it also must supportingly carry out.
The supporting protector of usual manhole is for arrange safety net at well head, the installation process of conventional security net is for opening well lid, put down bamboo ladder, workman enters in manhole along bamboo ladder, safety and borehole wall situation in manhole, then the correct position near well is selected, in same level, six deciles or eight equal parts carry out mark, with Churn drill in the boring of borehole wall mark position, imbed the expansion bolt of buckle, on expansion bolt, hang up safety net subsequently, complete the installation of safety net.Whole work progress needs 3 workmans and works 2 hours, needs to be equipped with engineering truck, generator, Churn drill, bamboo ladder and other conventional tool simultaneously, improves installation cost, reduces installation effectiveness.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of safety device of municipal manhole, this device conveniently can be implemented installation, safeguards, change operation, be applicable to the security protection of all kinds of manhole, improve installation exercise efficiency, reduce construction cost, the personal safety accident that can effectively avoid manhole cover loss to cause.
For solving the problems of the technologies described above, the safety device of the utility model municipal administration manhole comprises well lid and safety net, also comprise annular well head frame, some hook bolts and some hooks, the well head stepped locations of manhole is located at by described annular well head frame, described well lid is covered in the inner ring of described annular well head frame, described some hook bolts twist the lower edge in described annular well head frame inner ring uniformly at intervals, and described safety net connects described some hook bolts by described some hooks.
Further, described hook is self-closing annular hook.
Further, described safety net is nylon anti-drop net.
Because the safety device of the utility model municipal administration manhole have employed technique scheme, namely this device comprises well lid and safety net, also comprise annular well head frame, some hook bolts and some hooks, the well head stepped locations of manhole is located at by described annular well head frame, described well lid is covered in the inner ring of described annular well head frame, described some hook bolts twist the lower edge in described annular well head frame inner ring uniformly at intervals, and described safety net connects described some hook bolts by described some hooks.This device conveniently can be implemented installation, safeguards, change operation, is applicable to the security protection of all kinds of manhole, improves installation exercise efficiency, reduce construction cost, the personal safety accident that can effectively avoid manhole cover loss to cause.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the safety device schematic diagram of the utility model municipal administration manhole;
Fig. 2 is annular well head frame and some hook bolt connection diagram in this device;
Fig. 3 is the schematic diagram linked up with in this device.
Detailed description of the invention
As depicted in figs. 1 and 2, the safety device of the utility model municipal administration manhole comprises well lid 1 and safety net 2, also comprise annular well head frame 3, some hook bolts 4 and some hooks 5, the well head stepped locations of manhole 6 is located at by described annular well head frame 3, described well lid 1 is covered in the inner ring of described annular well head frame 3, described some hook bolts 4 twist the lower edge in described annular well head frame 3 inner ring uniformly at intervals, and described safety net 2 connects described some hook bolts 4 by described some hooks 5.
Further, described hook 5 is self-closing annular hooks.
Further, described safety net 2 is nylon anti-drop nets.
In this device, annular well head frame and well lid can adopt composite material to make, improve workability, reduce weight and cost of manufacture, hook bolt and hook adopt stainless steel material, avoid corrosion, hook bolt can adopt six or eight and annularly well head frame inner ring is uniform; The each parts of this device can assemble in factory, are directly transported to manhole scene during installation, and this device assembled directly is covered in manhole well head., the well lid that installation process only needs a workman to open manhole just can complete, and greatly improves installation effectiveness.
This device can conveniently be implemented to install the operation of safe fall-proof net, be applicable to the occasion of the manholes such as little regional park, nonmotorized vehicle lane, sidewalk, greenbelt, improve the efficiency of construction maintenance, reduce the cost of construction, avoid the manhole cover loss because the reasons such as damaged, heavy rain washes away, theft cause and cause pedestrian to fall the personal safety accidents such as well.And do not affect the original technical data of manhole, do not affect the construction technology of manhole, and the construction technology of installing safe fall-proof net simplifies greatly, improve installation effectiveness, reduce safe fall-proof net construction and installation cost, stopped the potential safety hazard of manhole.
