二、地下室工程的防水施工
Two 、 basement waterproof construction
对于防空地下室来说,防水质量可以说是工程是否能够达到设计使用功能的决定性因素,任何材料、设计、施工、管理方面的缺陷都会通过渗漏这一特殊的方式表现出来。
In the basement, the waterproof quality can be said to be the decisive
factor of whether the project can meet the design function, the defects
of any material, design and construction, management will be through the
leakage this special form.
(一)、砼构件引起的渗漏
(1) leakage caused by concrete members;
1、混凝土蜂窝、麻面、露筋、孔洞等造成地下室渗水,主要原因是配合比不准,坍落度过小,长距离运输和自由入模高度过大,造成混凝土离析;局部钢筋密集或预留洞口的下部混凝土无法进入,振捣不实或漏振,跑模漏浆等。针对以上情况对混凝土应严格计量,搅拌均匀,长距离运输后要进行二次搅拌。对于自由入模高度过高者,应使用串桶滑槽,浇筑应按施工方案分层进行,振捣密实。对于钢筋密集处,可调整石子级配,较大的预留洞下,应预留浇筑口。模板应支设牢固,在混凝土浇筑过程中,应指派专人值班“看模”。
1, concrete honeycomb, surface voids, reinforcement and holes caused by
water seepage in basement, the main reason is to mix, the slump is too
small, long distance transportation and free die height is too large,
resulting in lower part of the concrete reinforced concrete segregation;
dense or reserved hole can not enter, vibrating false or leak
vibration. Run mode leakage. In view of the above circumstances,
concrete should be strictly measured, mixing evenly, long distance
transportation after two mixing. For the high degree of freedom to enter
the mold, should use a series of bucket chute, pouring should be
layered according to the construction plan, vibration compaction. For
reinforcing bars, the gravel gradation can be adjusted, and the pouring
holes shall be provided under the larger reserved holes. The formwork
shall be firmly supported. In the process of concrete pouring, a special
person shall be assigned to watch the mould on duty".
2、混凝土结构的施工缝也是极易发生渗水的位置,其渗水主要原因为施工缝留设位置不当;施工缝清理不净,新旧混凝土未能很好结合;钢筋过密,混凝土捣实有困难等。防止施工缝部位渗水可采取以下措施:首先施工缝应按规定位置留设,防水薄弱部位及底板上不应留设施工缝,墙板上如必须留设垂直施工缝时,应与变形缝相一致。其次施工缝的留设、清理及新旧混凝土的接浆等应有统一部署,由专人认真细致地做好。还有设计人员在确定钢筋布置位置和墙体厚度时,应考虑方便施工,以保证工程质量。如发现施工缝渗水,可采用防水堵漏技术进行修补。
2 construction of concrete structure, seam is prone to leakage location,
the main cause of water seepage for construction joints remaining
improper location of construction joints; clean up dirty, not a good
combination of new and old concrete; reinforced concrete tamping is too
dense, difficult. Construction joints to prevent seepage may take the
following measures: first, the construction joint shall be in accordance
with position setting, waterproof weak parts and the bottom plate
should not leave construction joints, leaving the vertical construction
joints such as wallboard must, should be consistent with the deformation
joint. Secondly, the construction of the joint stay, cleaning, and new
and old concrete pulp should be unified deployment, by special personnel
to do a good job. There are designers in determining the location of
steel reinforcement and wall thickness, should consider the convenience
of construction, in order to ensure the quality of the project. If it is
found that the construction joints water seepage, waterproof plugging
technology can be used to repair.
3、混凝土裂缝产生渗漏。混凝土裂缝产生的原因很多,可由于干缩、温度、水泥用量过大或水泥安定性不好等因素引起。防水混凝土所用水泥必须经过检测,杜绝使用安定性不合格的产品,混凝土配合比由试验室提供,并严格控制水泥用量。对于地下室底板等厚大体积的混凝土,应遵守大体积混凝土施工的有关规定,严格控制温度差。设计时应综合考虑诸多不利因素,使结构具有足够的安全度,并合理设置变形缝,以适应结构变形。
3, concrete cracks. There are many causes of concrete cracks, which can
be caused by such factors as dry shrinkage, temperature, excessive
cement content, or poor cement stability. The cement used for waterproof
concrete must be tested to prevent the use of unstable and substandard
products. The concrete mixture ratio is provided by the laboratory and
the cement dosage is strictly controlled. For thick mass concrete such
as basement slab, we should obey the regulations of mass concrete
construction and strictly control the temperature difference. In the
design, a lot of unfavorable factors should be considered synthetically,
so that the structure has enough safety degree, and the deformation
joint should be set reasonably to adapt to the structural deformation.
4、预埋件部位产生渗漏。产生渗漏的原因有预埋件过密,埋件周围混凝土振捣不密实;在混凝土终凝前碰撞预埋件,使预埋件松动;预埋件铁脚过长,穿透混凝土层,又没按规定焊好止水环;预埋管道自身有裂缝、砂眼等疪病,地下水通过管壁渗漏等。为防止预埋件部位产生渗漏,可采取以下方法:预埋件应有固定措施,预埋件密集处应有施工技术措施,预埋件
钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修 铁脚应按规定焊好止水环。地下室的管线应尽量设计在地下水位以上,穿墙管道一律设置止水套管,管道与套管采用柔性连
4, embedded parts leakage. Causes of leakage of the embedded parts are
too dense, buried around the concrete vibrating compaction; before the
final set of concrete collision embedded parts, make embedded parts
loose; embedded iron feet long, penetrating the concrete layer, and not
in accordance with the provisions of the welded seal ring; buried
pipeline has cracks, trachoma and other disease problems, groundwater
through the wall leakage etc.. In order to prevent the leakage location
of embedded parts, can take the following methods: embedded parts should
be fixed at the proper measures, technical measures for the
construction of intensive embedded parts, iron feet shall be embedded
parts welding sealing ring. The basement pipeline shall be designed
above the water level, and the water supply pipe shall be provided
through the pipe through the wall, and the pipe and casing shall be made
of flexible connection
