[背景材料] 某建筑工程，地下1层，地上16层。总建筑面积28000m2，首层建筑面积2400m2，建筑红线内占地面积6000m2。该工程位于闹市中心，现场场地狭小。 施工单位为了降低成本，现场只设置了一条3m宽的施工道路兼作消防通道。现场平面呈长方形，在其斜对角布置了两个消火栓，两者之间相距86m，其中一个距拟建建筑3m，另一个距拟建建筑43m。 为了迎接上级单位的检查，施工单位临时在工地大门入口处的围墙上临时悬挂“五牌”、“二图”，检查小组离开后，项目经理立即派人将之拆下运至工地仓库保管，以备再查时用。 [问题]1.该工程设置的消防通道是否合理请说明理由。

In these years, economic, social and technological factors have influenced the kitchens’ design. 61) Since it is often used simultaneously by both family members as well as guests, the kitchen requires not only a glamorous look but a practical one. Also, the design elements must meet the needs of modem family.Environmental concerns have had an enormous impact on the design of kitchens. 62) This concern includes recycling of household materials, as well as energy efficient appliances and the purity of both water and air. Research shows that up to 85 percent of the population is concerned about what comes out of their tap. This is why it’s important to consider adding a water filter system.63) The character of today’s kitchen is very different from the way it was thirty years ago. There’s more sophistication in food preparation, and more technological help with cooking and cleaning up. When choosing cabinets, first consider the style. Use the architectural style of your house as guide. Because cabinets are a big investment, it is best to choose quality. Popular styles in kitchen cabinets are framed panel doors with raised or recessed panels of wood, cabinet fronts with glass panes, or simple slab doors in a rich painted or laminated finish. Cabinet pulls, handles and knobs are offered in a myriad of designs and finishes. Treat hardware as jewelry and don’t be afraid to mix and match styles.64) Because many of today’s kitchens consist of two or more cooks sharing in the meal preparation, there is a need for more counter space, cooktops and sinks. Life styles are changing, but the primary function of the kitchen as an area for preparing food has remained unchanged. The sink remains one of the most used areas in the kitchen as well as an important decorative statement.Appliance technology is moving very fast. Choosing what type of appliances as well as how many will depend on several factors such as how often and how much you cook and the size of your kitchen.Don’t limit yourself to one of each kind of appliance. 65) You can have a refrigerator in one place and a freezer in a separate area or two sets of cooktops: one on the counter next to the wall oven and one on an island. You can even have two dishwashers if size and budget require and permit -- think of it as saving time in the long run. Since it is often used simultaneously by both family members as well as guests, the kitchen requires not only a glamorous look but a practical one.
