This engineering refers to leading-in of the municipal water source where the project is undertaken; the water pressure at where two water supply pipes are connected into is greater than or equal to 0.3 MPa.

进入场地后设总进水表及倒流防止器,管网环状布置。

After the pipes enter into the site, are installed a general intake gauge and a backflow stopper; and the pipe network is arranged in a circular state.

2.室外消防给水系统:

Outdoor fire-fighting water supply system:

该工程室外消防流量25L/S,室外生活及消防合用给水管网上设置室外地上式消火栓2套。

The outdoor fire-fighting flow of this engineering is 25L/S; and 2 sets of outdoor overground fire hydrants are mounted on the outdoor domestic and fire-fighting water supply pipe network.

3.污水系统:

Sewage system:

1) 本工程采用生活污水与雨水分流制管道系统。

This engineering includes separated system of domestic sewage and rainwater.

2) 场地内生活污水经室外污水管网收集后进入新建化粪池。

The domestic sewage within the site is collected by the outdoor sewage pipe network and then gets in the newly-built septic tank.化粪池采用钢筋砼结构,型号为G7-20SQF,容积20m%%179

The septic tank is structured by reinforced concrete, with the type of G7-20SQF, volume of 20m%%179.

4.雨水系统:

Rainwater system:

本工程场地内屋面雨水及室外场地雨水,经新建室外雨水管网收集后排入市政雨水系统中。

The roof rainwater within the site and outdoor rainwater on the site is collected by the newly built outdoor rainwater pipe network and then drained to the municipal rainwater system.

本楼年雷击次数为0.0541/a,按《建筑物防雷设计规范》第2.0.4条规定属于第三类防雷建筑物。建筑物的防雷装置应满足防直击雷、防雷电感应及雷电波的侵入,并设置总等电位联结。

The number of lightning of the building is 0.0541 times/a every year, and it belongs to the third class building according to the provisions of Article 2.0.4 stipulated in Code for design of lightning protection of buildings. Building lightning protection devices shall prevent the invasion of anti-direct lightning, induction lightning and lightning waves, and the main equipotential bonding is set.

2.接闪器:

在屋面及女儿墙顶部设置10镀锌圆钢作避雷带。屋顶避雷带连接网格不大于20mX20m16mx24m

2. Air-termination system:

10 galvanized round steel is set at the roof and the top of parapet as lightning belt. The grid connected the roof lightning belt is not greater than 20mX20m or 16mx24m.

3.引下线:

Down lead

利用建筑物钢筋混凝土柱子或剪力墙内两根16以上主筋通长焊接作为引下线,引下线间距不大于25m.

The reinforced concrete columns of the building or two 16 above reinforcement within the shear wall are in full length welded as down lead, and the spacing between down leads is not more than 25m.

4.接地极:Grounding pole:

利用建筑物基础作接地体,利用-40x4渡锌扁钢将结构独立基础内的钢筋焊接连通作接地装置,要求接地电阻不大于1, 如不满足要求,应另加设人工接地装置。引下线上端与避雷带焊接,下端与接地极焊接。在有    符号的引下线所在结构柱上距地0.5m处连接板(接地电阻测试点)。

The building basis is used as the grounding body, -40x4 galvanized flat steel is used to weld and connect reinforced bars within the independent basis of the structure as the grounding device, and the grounding resistance is less than 1ohm as required; if not, an additional artificial grounding device should be set. The upper end of the down lead is welded and connected with the lightning belt, and the lower end is welded with the grounding pole. Plates are connected 0.5m from the ground on the structure column of the down lead where there is  symbol (earth resistance test point).

5.凡突出屋面的所有金属构件、金属屋面、金属屋架、金属雨棚、钢柱等均与避雷带可靠焊接。突出屋面的所有金属构架至少应在两对角支撑点处与避雷带可靠焊接。不同高度的屋面接闪器应利用结构柱内主筋或沿墙暗设10镀锌圆钢焊接连通。竖直敷设的金属管道及金属物的顶端和底端应与防雷装置连接。电源引入的总配电箱处均装设过电压保护器。

5. All the metal members prominent on the roof, metal roofing, metal roof truss, metal canopy, steel columns and others are welded with lightning belts reliably. All the metal members prominent on the roof should be welded with lightning belts reliably at least at two diagonal support points. Different heights of roof air-termination systems should be welded and connected by use the main reinforcement in the structure column or by setting 10 galvanized round steel along the wall. Vertically laid metal pipelines and metal top and bottom should be connected with lightning devices. An over-voltage protector is installed at the general power distribution box where the power supply is input.
