(1)基础扩大法:通过设置混凝土围套或钢筋混凝土围套,增加广告牌底部基础的面积,改变因济南广告牌基础底面积偏小、承载力不足而产生的地基不均匀沉降。

(1) the basic expansion method: by setting up concrete or reinforced concrete enclosure, increasing the area of the bottom of the advertising brand, and changing the foundation caused by the low area of the foundation of Ji'nan advertising brand, the bearing capacity is not uniform.

(2)坑式托换法:直接在被托换基础下挖坑后浇筑混凝土。

(2) pit underpinning method: direct in underpinning foundation after digging pouring concrete.

(3)桩式托换法:采用在济南广告牌 http://www.xiongdiguanggao.com/ 基础的下部或两侧设置静压柱、打入桩、灌注桩等各类桩来进行基础加固的方法。

(3) a pile underpinning method: a method for strengthening the foundation of the foundation reinforcement of the bottom or both sides of the Ji'nan advertising licensing foundation.

(4)灌浆托换法:将化学浆液均匀地注入地基中,通过这些浆液把原来松散的土质或裂缝胶结固化,以达到提高地基承载力,防水抗渗的作用。

(4) grouting underpinning method: the chemical grout evenly into the foundation, through which the original loose soil or crack cement curing, in order to improve the bearing capacity of the foundation, waterproof and anti permeability.

纠偏就是采用人为的手段使已倾斜的地基进行反向倾斜的操作,以达到矫正济南广告牌倾斜的目的。

Rectification is the use of artificial means to make the sloping ground to reverse the operation, in order to achieve the purpose of correcting the tilt of the Ji'nan advertising brand.

常用的济南大型广告牌地基纠偏的方法有以下几种:

The method of correcting the foundation of large billboards in Ji'nan has the following methods:

(1)迫降纠偏法:在济南广告牌基础沉降多的一侧面采取阻止下沉的措施,而在另一侧采取迫降措施。迫降方法包括:加载钢锭或石块、修建悬臂梁、掏土迫降、注水纠偏等。

(1) landing correction method: Jinan billboard based settlement one side take prevent measures to sink in, and on the other side take measures of landing. Landing method includes: loading steel ingot or stone, built a cantilever beam, forced settlement, water injection correction.

(2)顶升纠偏法:在倾斜广告牌基础沉降大的部位,通过调整广告牌各部分的顶升量,使其沿某一点或某一直线作整体平面转动,以达到恢复原位的目的。

(2) the top - up correction method: on the basis of a large part of the site of the settlement of the advertising plate, adjust the top of each part of the advertising board to rotate, so that it can be used as a whole plane to achieve the purpose of restoring in situ.

钢性架构的维护与加固

Maintenance and reinforcement of steel structure

由于钢材的强度高于常见的其他工程材料,因此户外广告牌的主体支撑架构通常都以钢性材料为主。而钢性材料在露天环境中,受气温、湿度、有害物质等因素的影响,极易被氧化而引起锈蚀,严重的锈蚀可使钢性构件抗荷载的能力大大降低;钢性材料具有良好的韧性,但在长期负载或低温状态下,钢性材料也易产生脆化和断裂;加之在济南广告牌的设计构筑过程中,在局部甚至整体稳定性上有缺陷;或在使用、维修、改装过程中因螺栓松动、超载、外力冲击等导致整体失衡;另外,使用劣质钢材构筑济南广告牌的主体结构;不考虑其负载能力,随意在济南大型广告牌上焊接其它钢板件等都会造成严重的后果。

Because the strength of the steel is higher than other engineering materials, the main support structure of the outdoor advertising brand is mainly based on the steel material. The impact of the material in the open air, humidity, and other factors, the corrosion of steel members can easily be oxidized, severe corrosion can be greatly reduced steel components, steel material has good toughness, but in the long-term load or low temperature state, steel material is easy to produce and brittle, combined with the Ji'nan billboard design and construction process, in the design and construction process, the use, maintenance, maintenance, modification process due to the use of, maintenance, modification process, due to the use, maintenance, modification process, due to the use, maintenance, modification process, due to the use, maintenance, modification process, due to the use, maintenance, external shocks, etc., in addition, the use of poor quality steel and other, the main structure of the use of poor quality steel. Consequences.

钢性架构的日常维护应注意以下几点:

The daily maintenance of steel structure should pay attention to the following points:

严格选材。要选择钢材时,要对钢结构所用钢材的化学成份、机械性能进行测试,并对钢材的外观进行检查,弃置有裂纹、锈斑和疤痕等缺陷的材料。

Strict selection. To select the steel to on the steel structure with steel chemical composition, mechanical properties test, and check the appearance of steel, and dispose of a crack, rust and scars and other defects of the material.

谨慎施工。在济南广告牌的构建过程中,应避免对所使用钢材的外表进行损伤,对关键的受力部位,禁止打孔和焊接。

Careful construction. In the construction process of Ji'nan advertising brand, we should avoid the appearance of the use of steel damage, the key to the site, the prohibition of drilling and welding.
