Description

Prevent subsiding cable shaft suitable for cable duct bank

Technical Field

The utility model relates to a cable duct bank technical field, concretely relates to prevent subsiding cable shaft suitable for cable duct bank.

Background

In a transformer substation, there are two main ways of leading out wires from inside to outside of a building of a switch cabinet, namely an overhead outgoing line type and a cable outgoing line type, and the two outgoing line ways have respective advantages and disadvantages: the overhead outgoing line type is more economical, but the maintenance amount is large, the number of connecting points is large, the overhead outgoing line type is easily influenced by severe weather and external force damage, and the range of accidents is not controlled; the cable outlet type is safer and more widely applied, but the safety of the cable outlet type can also be influenced by factors such as site geological conditions, embedding modes of cable pipes and the like, for example, when the cable is led out from the buried pipe, if a large settlement difference occurs at the junction of a building and the site and reasonable settlement prevention measures are not adopted, the buried pipe of the cable can be broken and other damage modes, the cable is damaged, and accidents are caused.

At the indoor outer handing-over department of building, traditional cable outlet method is that the cable calandria directly leads to the place from the building, do not establish the transition between them, this ramming and filling quality requirement to the basement backfill is very high, and require building and place uneven settlement very little, if the backfill compactness under the cable calandria is not up to standard, the uneven settlement of place and building has appeared, then the cable calandria appears the crack very easily, wholly clear even fracture, make the protection tube of cable calandria lose the function of protection, the cable easily receives soil and rainwater, groundwater etc. corrodes, cause the fracture damage of cable even, cause the accident. For coastal soft soil foundation, the bearing capacity characteristic value of the foundation is generally not more than 50kpa due to thick soft soil layer, and if no measures are taken, the settlement difference between a building and a site is generally more than 300mm, which is unacceptable for electrical professional design. Considering the cost, the field is generally treated by adopting a composite foundation, the pile length is generally short, and the difference between the pile length and the bearing stratum of the building pile foundation is large, so that the unavoidable difference still exists in the settlement difference.

Based on this, the utility model designs a prevent subsiding cable shaft suitable for cable duct bank to solve above-mentioned problem.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-3, the present invention provides a technical solution: an anti-settling cable well suitable for cable duct banks comprises a supporting base 1, wherein the periphery of the upper end of the supporting base 1 is fixedly connected with a brick wall 2, the brick wall 2 is provided with a plurality of groups of preformed holes 3 which are mutually matched at the left end and the right end, a cable 4 is arranged in each preformed hole 3, a supporting rod 5 is fixedly connected between the brick walls 2 at the front end and the rear end, the cable 4 is arranged at the upper end of the supporting rod 5, the upper end of the brick wall 2 is fixedly connected with a fixed ring 6, the upper end of the fixed ring 6 is fixedly connected with a supporting ring 7, the upper end of the inner side of the supporting ring 7 is provided with a groove 8, a threaded rod 9 is arranged at the bottom end of the groove 8 in the supporting ring 7, the lower end of the threaded rod 9 is fixedly connected to the bottom end in the supporting ring 7, the other end of the threaded rod, the lower end of the supporting plate 10 is rotatably connected with a threaded sleeve 12 through a bearing 11, the lower end of the threaded sleeve 12 is in threaded connection with the threaded rod 9, and a cover plate 13 is arranged at the upper end of the supporting plate 10.

Wherein, support base 1 lower extreme and seted up water catch bowl 14, water catch bowl 14 communicates in urban drainage pipe, and water catch bowl 14 can be used to collect the catchment in the cable shaft, discharges ponding to urban drainage pipe in through water catch bowl 14, avoids the well catchment too much to cause the damage to cable 4. Control both ends preformed hole 3 and be located same height, make the bearing structure at cable 4 both ends be in same height, it is low to avoid the high one end of 4 one ends of cable, thereby the eminence takes place to the circumstances such as low landing, 3 diameters in multiunit preformed hole are all inequality, can place the cable 4 of the different diameters of multiunit, bracing piece 5 with control both ends preformed hole 3 height-alike, play the supporting role to the middle-end of cable 4, avoid the long-time atress of cable 4 middle-end to lead to cable 4 outside insulating layer fracture. The inner side walls of the left and right brick walls 2 are fixedly connected with tension rings 15 at the lower ends of the preformed holes 3, and the tension rings 15 are used for fastening pulleys when cables 4 are laid. When the cable 4 is laid in the construction, the orifice of the preformed hole 3 is prevented from being damaged or cracked. The lateral wall end of the cover plate 13 is provided with a layer of rubber pad, raised dots are arranged on the surface of the rubber pad, the contact between the cover plate and the inner side of the groove 8 is increased, the cover plate 13 is prevented from shaking on the supporting ring 7, the stability is kept, and meanwhile, the cover plate 13 and the groove 8 are prevented from being damaged due to friction.

One specific application of this embodiment is: when the device is used, a proper preformed hole 3 is selected according to the diameter of a cable 4, a pulley is arranged on a tension ring 15 at the lower end of the preformed hole 3, then the cable 4 is pulled into the preformed hole 3 at the other end through the pulley, the pulley is convenient and labor-saving, the damage or the crack of the preformed hole 3 caused by the cable 4 is avoided, furthermore, the middle end of the cable 4 can be placed on a support rod 5 to support the cable 4, after the device is installed, a cover plate 13 can be installed on a support ring 7, because the cover plate 13 is flush with the road surface, a concrete cushion is needed when the base of the cover plate 13 is installed, because the base and a cable well body are separately poured, the concrete of the base can be damaged after a vehicle rolls for a long time, the cover plate 13 is settled and sags, therefore, the threaded sleeve 12 can be rotated to drive the support plate 10 to move upwards, and the height of the cover plate 13 is adjusted, the height of the cable well is consistent with the height of the road surface, and furthermore, the collected water in the cable well can be discharged into a city drainage pipeline through a water collecting groove 14, so that the damage to the cable 4 caused by excessive water collection in the well is avoided.
