Description
Technical field
The utility model relates to pipe manhole, belong to the ancillary structure of city planting ductwork facility, a specifically combined inspection shaft, it is particularly suitable for installing and using on the city planting ductworks such as optical-fibre communications, cable television, public lighting circuit, gas pipe and fire-fighting, plumbing.
Background technology
Along with the high speed development of Chinese national economy, the process that has effectively advanced Chinese Urbanization to build, in order to improve urban safety high efficiency smart operation level, need to lay such as optical-fibre communications specially at underground, cable television, public lighting circuit, gas pipe, the city planting ductwork such as fire-fighting and plumbing facility, can normally move steadily in the long term in order to ensure these pipe network infrastructure, generally all will be in pipeline intersection, turning, on caliber or gradient change place and straight line pipeline section, locate at a certain distance to build the vertical shaft that is exclusively used in maintenance overhaul, its objective is that being convenient to municipal pipeline maintenance management personnel is entered in pipeline and made regular check on and safeguard and repairing operation by vertical shaft.For a long time, the manhole of urban Underground pipeline is mostly to adopt traditional brick construction, but, the technical problem that in use exists all many-sides such as handling safety, environmental protection resource to be difficult to overcome due to this " manhole of laying bricks ", the Ministry of Construction of China just sent the documents and has clearly specified as far back as 2004: require to ban use of clay solid brick to build manhole, and the work of promoting Novel inspection well is researched and developed in active support on fund policy.Up to now, due to eliminating gradually of " manhole of laying bricks ", a kind of cement manhole of monobloc cast moulding is widely applied in municipal pipe network construction.We but find being engaged in for a long time in city planting ductwork equipment research and development and production installation practice: the cement manhole of this monobloc cast moulding is due to the large heaviness of body, in the manufacturing, transporting and hoisting and installation operation process, also there is many drawbacks, it has not only increased the expense of equipment in transhipment storage and installation, also increase the difficulty of on-site hoisting construction simultaneously and then affect installation exercise efficiency, seriously time, also can restrict the construction progress of city planting ductwork and incur loss through delay the construction period.In order to address this problem, some manufacturing enterprises start to attempt releasing the product of global formation all-plastic manhole (as polyethylene manhole), although it can alleviate the weight of manhole and have good toughness, but, still there is in actual use the structural defect of " bulky " in it, and because all-plastic manhole self material rigidity intensity is low, externally load-bearing voltage endurance capability is poor, easy crushing in actual use, this " all-plastic manhole " product that is existing exists that " rapid wear repair rate is high, working life is shorter " critical defect and a main cause being difficult to apply.This has become a pipe network equipment production industry and municipal administration department technical problem in the urgent need to address, and the utility model will address this problem just.
