Description
Technical field
The present invention relates to the underground distribution device in a kind of urban construction or power construction and installation method thereof, specifically, relate to cable shaft.
Background technology
Existing bilge well, catch-basin, storm-water inlet, combustion gas valve pit, power cable well, all kinds of weak-current cable well and other kinds common-use tunnel equipment raise generally adopt the masonries such as brick to build by laying bricks or stones, or adopt cast-in-place method to make concrete equipment raise in erecting bed. Wherein, cable shaft, is play in cable burial engineering in construction and the underground inspection shaft of installation or maintenance effect after completion of works. It is generally divided into manhole shaft and hand hole well. Manhole shaft is relatively larger, and people following can carry out constructing operation inside well. Hand hole well is generally smaller, and only hands can put in and be operated, and is typically all for branched line, and in well the cable of traverse few, main effect is to do an outdoor transitional function, during for dark applying, facilitates threading. What traditional cable shaft great majority used is all formed by brick or concreting.
Generally, in order to keep in repair facility, generally every cable all can leave reserve level in cable shaft, in case of need. in prior art, the cable in stock in each loop, access lines cable is stacked in same cable well after all unifying to be wound around lopping, now cable may Stagger-wrap together, even tie a knot, so occurring cable fault to need to use cable in stock constantly, can not quickly make cable in stock in order, it is difficult to extract cable in stock out carry out in time keeping in repair and handling failure, especially when cable is stacked, it is very difficult to find out the cable of bottommost, this cable is relatively heavy, generally require by extraneous instrument, fault time delay is longer, maintenance and troubleshooting are inconvenient, delay cable to use. additionally, when the cable in a loop breaks down, the cable in other loops also can receive impact, it is possible to related fault, the more important thing is, be likely to be placed with charged and uncharged cable with in a cable shaft simultaneously, forming maltilevel security hidden danger when construction and maintenance, especially when there is hydrops in well, charged will be more dangerous. What is more, and under the ground of mounted outdoor equipment during construction, both dangerous also inconvenient, especially construction space is minimum, when having an accident, it may be difficult to escape.
Additionally, it was verified that existing brick or concreting cable shaft be embedded in underground soaked by slowly drained soil and steam, dampness, acid-alkali salt corrode very easily corrosion spalling and lose waterproof ability, easily infiltration, poor durability, and intensity reduces, fragile; Arranging owing to cable distribution and cable shaft are both along road both sides, so such cable shaft is once damage that to have an effect on urban highway traffic unobstructed, being also unfavorable for the protection of groundwater resources. And use clay brick to cause clay resource to waste in a large number, do not meet environmental protection policy; What is more, with existing structure, when checking some specific demand of cable, it is necessary to brick is knocked out, then could check, so not only lost time but also work consuming, must lay bricks after then having overhauled again, thus caused very big waste. Or utilizing well lid to close in the structure of cable shaft, the structural strength of well lid is not enough again, in-convenience in use.
