Description
Technical field
The utility model relates to the common buildings grounding system, particularly a kind of subway loam cake property synthesis grounding system.
Background technology
Subway loam cake property synthesis generally is ground multilayer or high-rise commerce or office premises, and underground multilayer contains the station.Usually the subway station utilizes reinforcing bars of structural columns to collect stray electrical current, corrodes municipal pipeline and facility to prevent stray electrical current beyond being diffused into main body.Because the diaphragm wall of the underground main body of synthesis is outside at waterproofing course, each layer floor bar and diaphragm wall reinforcing bar adopt welding method to link together, the reinforcing bar of plate adopts welding method to link together in steel pipe column or reinforced concrete post and top board, negative, each layer, uplift pile reinforcing bar and negative reinforcing bar adopt welding method to link together, so agent structure post reinforcing bar has been realized good ground connection by uplift pile, diaphragm wall reinforcing bar, agent structure can't shield stray electrical current to the subway external leakage.
Above ground portion generally should be as the Equations of The Second Kind Lightning Protection Building, will utilize routinely in the post reinforcing bar to do down lead and connects with ground device, i.e. structure and ground device electric connection of needs.Underground main body is as the subway station, and subway adopts DC traction, need to take the stray current corrosion safeguard procedures, should insulate by current specifications structure and ground device.Because ground, underground structure are one, if grounded screen and under ground portion insulation also should be insulated with overground part.But the lightning protection device of superstructure is communicated with agent structure, adopts integrated ground just to utilize inevitably grounding structure, and has contradiction between the stray current corrosion protection.Agent structure should not be re-used as the auxiliary collecting net of stray electrical current.
Summary of the invention
The purpose of this utility model is to provide the subway loam cake property synthesis grounding system that a kind of Manual earth network construction process requirement that can solve contradiction between integrated ground and the stray current corrosion protection and employing and structural insulation is high, invest a large difficult problem.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of subway loam cake property synthesis grounding system, comprise and be arranged on the following pile foundation of subway station underground building base plate, be arranged on the metal Roof of subway station superstructure top layer or artificial arrester, vertically run through and entirely go up underground building and the reinforcing bars of structural columns, the railway roadbed reinforcing bar that is arranged on the railway roadbed bottom that are connected with metal Roof and pile foundation respectively of two ends and be arranged on electric substation in the subway station underground building up and down, reinforcing bars of structural columns directly contacts with the building structure of subway station, the railway roadbed reinforcing bar is connected with electric substation, consists of the loop; Be provided with M type Equipotential network in system, lead to some ground busbar from reinforcing bars of structural columns, ground busbar connects by cable each other; The railway roadbed reinforcing bar is as the stray electrical current collecting net, with the equal insulation processing in adjacent interval structure connecting sewing place; The reinforcing bars of structural columns of subway station and the adjacent electric disconnection of tunnel construction sections reinforcing bar.
Utilize the underground bottom pile foundation of engineering as the integrated ground device, draw from base arrangement post reinforcing bar that some forceful electric power protection groundings are always arranged, electrical grounding is always arranged.Simultaneously, adopt M type Equipotential network in system, various ground busbar connect by cable, and every layer electrical grounding terminal box also laterally connects by cable.Utilize surface structures metal Roof or artificial lightning conduction, lightning rod to do arrester, reinforcing bar is done down lead in the post, utilizes Main Underground body structure pile foundation to make ground device.
The surface structures part is carried out division and the surge protection setting of lightning protection zones routinely; introducing, the loop of drawing building and electric substation's low pressure inlet wires such as under ground portion access awning, cooling tower arrange surge protection by the first order; electric substation's low-voltage bus bar arranges surge protection by the second level, and the switchbox in weak current equipment room arranges surge protection by the third level.
Because reinforcing bars of structural columns directly contacts with the building structure of subway station, subway loam cake property synthesis utilizes structure as natural grounding substance, only implements equal pressure zone in the electric substation room.
Compare the Manual earth network that adopts with structural insulation, the utility model need not to take insulation measures and waterproof measure between reinforcing bars of structural columns and structure, and design and construction process requires simple, small investment.In addition, utilize reinforcing bars of structural columns to do natural grounding substance, still to the recycling of this resource of agent structure, saved a large amount of non-ferrous metals, insulation materials and the extra construction and installation expense of the outer worker's grounded screen that induces one.The reinforcing bar of Metro Station Structure consists of a huge equipotential farad cage, for general station, this faraday cup has several ten thousand steres approximately, is very easy to realize the ground resistance of requirement, can be used as the composite earthing network of subway fully, this is that any Manual earth network is incomparable.Therefore, no matter from technology or economic aspect, utilize agent structure to do grounded screen and all significantly be better than Manual earth network of the prior art.
Description of drawings
Fig. 1 is the structural representation of the utility model subway loam cake property synthesis grounding system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described in detail.
As shown in Figure 1, a kind of subway loam cake property synthesis grounding system comprises being arranged on the following pile foundation 1 of subway station underground building base plate, being arranged on the metal Roof 2 of subway station superstructure top layer, vertically running through and entirely go up underground building and the reinforcing bars of structural columns 3, the railway roadbed reinforcing bar 4 that is arranged on the railway roadbed bottom that are connected with metal Roof 2 and pile foundation 1 respectively of two ends and be arranged on electric substation 7 in the subway station underground building up and down; Reinforcing bars of structural columns 3 directly contacts with the building structure of subway station; Railway roadbed reinforcing bar 4 is connected with electric substation 7, consists of the loop; Be provided with M type Equipotential network in system, lead to some ground busbar from reinforcing bars of structural columns 3, ground busbar connects by cable each other; Railway roadbed reinforcing bar 4 is as the stray electrical current collecting net, with the equal insulation processing in adjacent interval structure connecting sewing place; The reinforcing bars of structural columns 3 of subway station and the adjacent electric disconnection of tunnel construction sections reinforcing bar.
