Technical field
This utility model relates to field of power transmission, is specifically related to a kind of prefabricated steel and moulds cable pipe trench.
Background technology
While China " on the ground " builds and develops rapidly, the construction of " underground " engineering but rests on traditional mode always, there is bigger gap with the Western European countries.
For the outstanding problem that long-standing Urban Underground infrastructure falls behind, Premier of the State Council Li Keqiang points out will from China's actual conditions, use for reference international advanced experience, build for concentrating the underground pipe gallery laying the municipal pipelines such as electric power, communication, broadcasting and TV, plumbing, heating power in city.
Cable duct is one of infrastructure important during Urban Underground is built, and in current Urban Underground infrastructure construction, cable pipe trench adopts traditional concrete cast-in-situ form. The shortcomings such as the cable duct of this form in use also exists operational procedure complexity, long construction period, service life is short, operation and maintenance expenses are high.
Summary of the invention
For above-mentioned prior art, the technical problems to be solved in the utility model is in that to provide a kind of easy construction, short construction period, long service life, and cable pipe trench moulded by the prefabricated steel that easy to maintenance, operation and maintenance expenses are low. This pipe trench be a kind of environmental protection, energy-conservation, can prefabricated product, can be used for country and carry out upgrading urban and rural power grids engineering, it is achieved the general requirement that supervisor ministries and commissions of country " put cable underground ".
For solving above-mentioned technical problem, this utility model provides a kind of prefabricated steel and moulds cable pipe trench, the cable bearer moulded cable pipe trench including steel, be arranged in cable pipe trench, is provided with the ventilation mouth of pipe in described cable pipe trench, the described ventilation mouth of pipe is connected with air inlet and air outlet by ventilation shaft.
Adopt this structure, it is possible to simplify cable duct construction technology, improve cable duct protection against the tide, antiseptic property, drastically increase the service life of cable duct, reduce cable duct operation and maintenance expenses use, save equipment investment, accelerate speed of application, there is bigger economic benefit; Prefabricated steel is moulded cable duct and is provided with Multiple Type, according to actual demands of engineering flexible customization, can improve cable duct construction complexity greatly, adopt this pre-manufactured steel to mould cable duct, it is possible to accelerate speed of application, reduce situ wet operation; Mould at steel simultaneously and the ventilation mouth of pipe and entry/exit air port are set in cable duct, meet heat dissipation ventilation requirement.
As further improvement of the utility model, the described ventilation mouth of pipe arranges a place every 70m. Adopt above structure, in cable pipe trench, be provided with the ventilation mouth of pipe, ventilation and heat requirement can be met.
Further improve as of the present utility model, it is provided with access hole and discharge outlet in described cable pipe trench, access hole and discharge outlet can be set according to related specifications in ditch, it is easy to the interior maintenance of pipe trench, draining, arc threeway, four-way inspection shaft can be set according to different project situation in pre-fabricated electric cables ditch, and safety vent is set at inspection shaft.
Further improving as of the present utility model, also include prefabricated fire resistant doorsets and fire wall, fire wall arranges a place every 75m, and fire wall thickness is not less than 100mm. Fire resistant doorsets and fire wall can be set according to relevant regulations and code inside cable duct, meet power industry fire-fighting requirements.
Further improve as of the present utility model, be provided with an elongated grounding flat steel in described cable tube furrow bank, square steel tube is welded with elongated grounding flat steel, and one place's Earth pile-head is set every 10m, connect for grounding lead. Meet the requirement of ground connection in code.
Improving as another step of the present utility model, described air outlet place is provided with rainhat.
In sum, above-mentioned prefabricated steel is used to mould cable pipe trench, it is possible to simplify cable duct construction technology, improve cable duct protection against the tide, antiseptic property, drastically increase the service life of cable duct, reduce cable duct operation and maintenance expenses and use, save equipment investment, accelerate speed of application, there is bigger economic benefit; Prefabricated steel is moulded cable duct and is provided with Multiple Type, according to actual demands of engineering flexible customization, can improve cable duct construction complexity greatly, adopt this pre-manufactured steel to mould cable duct, it is possible to accelerate speed of application, reduce situ wet operation; Mould at steel simultaneously and the ventilation mouth of pipe and entry/exit air port are set in cable duct, meet heat dissipation ventilation requirement. The all of reserved mouth of pipe all have accordingly can prefabricated corollary equipment, well ensure that the integrity of cable duct pattern and uniformity, real achieves the requirement that cable duct is all prefabricated.
