Sufficient of Sun irradiation, especially winter can makes sheds warm, and dry and eradication disease original microbial, j so, using natural lighting of sheds first to select good sheds of azimuth, towards South sunny better? second, Windows of area size also to appropriate, species with sheds Windows and ground area of than to 1:5 better, meat with sheds is relative small some: closed type sheds to gives strength right of artificial lighting, as degrees lower not conducive to chicken group of produced egg. as degrees partial high both waste power and easy caused sucking fetish of occurred. Hen activities take place inside the hens chicks and laying hens illuminance of 10 lux and 5~10, respectively. (5) the right density: stocking density is directly related to the health, growth, development and performance. Density is too little equipment investment increased stocking density reduced weight gain, increased egg mortality of the General Assembly. Therefore, the chicken area must be consistent with the capacity of appropriate density. (6) for disinfection and epidemic prevention: in order to improve the sterilization effect of wall surface to be smooth, there must be concrete and Dado. hen-house population should be equipped with disinfection of pools: mechanical scraping manure sheds its outward of the gutter should be placed in the 一、 工程概况 福州生态温泉城---疗养度假及旅游综合配套项目2#楼，本工程地 2上七层，局部五层、六层，建筑面积5503.65m，建筑物的层高:底层是4.07m，2,7层的层高均为3.10m，闷顶层的层高为1.43m，屋面层的层高为3.3m，建筑物的总高度为23.8m。砼的强度等级:墙、柱分别为C35、C30、C25四个等级;梁、板分别为C30、C25两个等级，本工程的基础采用预应力管桩，管桩的规格为PHC-500，AB型号，单桩的竖向承载力特征值为2000KN，锤击控制的贯入度为30mm/10击，静压重压力为400t，施工的总桩数为111根，采用“圆锥形”桩尖，桩基施工开工于2013年7月20日,,013年7月28日，基础施工时间为2013年8月,2013年9月，在福建六建集团有限公司精心安排下，组织精干力量，按照建设单位要求的节点工期目标，完成地基与基础的施工。 本工程的主体结构形式为钢筋砼框架结构，基础为预应力管桩，桩承台和地梁相连的基础形式，预应力管桩进入持力层的深度:卵石层为大于或等于3m，设计结构使用年限为50年。抗震设计等级为三级。 二、监理工作情况 受业主委托，项目监理部依据《监理合同》、《施工合同》和工程建设的有关规范、法律法规等要求对桩基子分部施工进行了全过程监理。结合《监理规划》、《旁站监理》及《监理》制定了现场监理工作制度和监理工作流程，指导施工过程中的各项监理工作。桩基施工前，先进行试桩，并制定试桩标准，然后根据试桩标准，再of relative humidity's not over 65%, Yu into and the layers homes requirements 55~65%: to prevent humidity had big. also must has enough of ventilation volume, built cement ground, don't in low-lying at built sheds,, (4) sufficient of Sun irradiation: this main on open sheds,.
