GC灌浆质料正在合肥ABB公司运用状况实例

一、注浆前厂房地坪的状况

合肥ABB公司是一家消费大型变压器的中外合资企业,是正在合肥变压器厂基础上改建而成,消费车间应用局部旧厂房,其地坪承载的力小,而ABB公司消费的均是大型变压器,每台重100-150吨,因为遭到临时超载运用,地坪下沉严峻,地区面积2000余平方米,有的下沉深度凌驾15cm,严峻影响了消费一般运用。

二、地坪注浆状况

往年蒲月我公司应ABB公司要求,负担了ABB公司地坪注浆工程。

1.用上陆地泾水泥厂消费的GC灌浆材质料(地坪公用)停止单液注浆

GC灌浆质料的主要性能:

凝聚工夫初凝:1:02

终凝:1:31

自在膨胀率1天0.10%

28天0.23%

净浆强度(Mpa)1天25.0

28天55.0

2.厂房地坪注浆面积2100平方米,注浆量30000余立方米。

3.注浆要领

灌浆质料加水机器搅拌后,用压力泵将冻液注入灌浆孔,注浆终了后将注浆孔关闭。

三、运用结果

用上陆地泾水泥厂消费的GC灌浆质料(地坪公用)停止单液注浆完毕后下沉地坪上升规复原状(地坪高差小于1cm)第三天地坪可一般运用,安排重达100-150吨的变压器,至今已注浆加固的厂房地坪经由四个多月的载荷运用,没有发明下陷征象,用户反应优越。

此次合肥ABB公司地坪注浆获得予期的优越结果。因为分期分批停止注浆,出有影响一般消费。上陆地泾水泥厂消费GC灌浆质料是一种无机单液灌浆料,本钱低、强度下、耐久性好、施工轻易、奏效快,可作为地基加固或其他工程部位的灌浆质料。

GC Grouting Material Application Example in ABB Company

I. Factory building floor case before grouting

ABB Company was a sino-foreigtn joint-venture enterprise which produced large-scale transformers,which was established on the base of Hefei Transformer Factory.The existing factory building was used for production workshop,its floor loading force was small,while ABB Co.produced large-scale transformers,each equipment was 100-150t.As overloading had been undertaken for a long time,the floor was subsidence seriously,the area was up to over 2000 m2,some went down over15cm,which affected production seriously.

II. Floor Grouting Case

Invited by ABB Co last May,out company undertook floor grouting engineering for ABB Co.

1. GC Grouting Material(Special for Floor)produced by shanghai Yangjing Cement Factory was cast by single liquid grouting.The main properties of GC Grouting material were as follows:

1) Condesing time:Primary condensing:1.02

Final condensing:1.31

2) Free expansion rate:1 day 0.1%

28 day 0.23%

3) Net Mortar Srength(Mpa)1day 25.0

3day 36.0

28day 55.0

2. Grouting Area offactory building floor 2100m2,trouting quantity over 30000m3.

3. Grouting Method:

After water was added with grouting material and mixed by machine,the pressure pump was used for casting grouting into grouting holes,after grouting,the grouting hole should be sealed.

Result of use:

GC Grouting material(special for floor)produced by Shanghai Yanjing Cement Factory was cast by single liquid grouting,after grouting the factory building floor returned to the original situation(the floor error was less than 1cm),the 3rd day the floor could be used ,and 100-150t transformers,so far 4 months has passed,any mistakes had not been found,the customer felt it very good.

This Hefei ABB Co.floor grouting achieved good result which we expected.Using separating and batch by batch grouting,so it did not affect the normal production.GC Grouting Material produced by Shanghai Yanjing Cement Factory was a inorganic single liquid grouting material,with low cost,high strength,good durability,convenience construction,and seeing fast result,and it could be used for foundation reinforcement or other engineering grouting material.

特快硬混凝土正在大面积施工运用胜利

Express Hard Concrete Large Area Construction Application Successful

由上海市政工程研究院研制的特快硬混凝土正在上海市地道管理处的支撑下,正在洋泾水泥厂的合营下,89年正在上海市打浦路越江地道大面积水泥混凝土路面抢修工程中获得成功。

打浦路地道路面因为临时遭到地下水腐蚀,不均匀沉降,忙碌的交通流量及超载等身分的影响,破坏面积较大,路面板体破裂严峻。针对庞大路况,上海市市政工程研究所联合地道的实际情况,改动一样平常路面混凝土的施工工艺,使路面混凝土的平整度、精糙度、强度及耐磨性均到达了应急抢修的要求,完成了2800平方米的路面抢修义务。

特快硬混凝土及其维修手艺的研制是市建委针对上海市市政设备近况下达的科研项目,它的胜利运用弥补了水泥混凝土路面快速修补的空缺,其大面积运用已到达天下程度。

特快硬混凝土是采用上陆地泾水泥厂消费的硫铝酸盐超早强水泥,并取厂特种水泥运用技术研究土的易施工性,又补充了一般混凝土摄生期少影响城市交通的缺点。如:可大面积一连浇筑,浇后仅养护四小时便能通车(四小时抗压12.0Mpa抗折2.8Mpa)削减交通忙碌和要塞路段空中施工带来的影响。

理论证实,接纳特快硬混凝土维修水泥混凝土路面,其用度近低于环氧混凝土及其它早强混凝土,具有优越的经济效益,它的胜利运用也为市政工程的水泥混凝土路面革新和应用拓荒了一条新的路子具有辽阔的运用远景。

With the support of Shanghai Tunnel Administration and coordinating of Shanghai Yangjing Cement Factory,the express hard concrete developed by Shanghai Municpai Project Institute was used successfully for emergency large cement concrete road surface repairing engineering of Shanghai Dapu Road Cross-Over Wangpu River Tunnel.

Dapu Road Tunnel road surface was suffered from underground water subsidence,busy traffic and heavy loading,etc.influences,the large area of surface broken and damaged.For the complex road situation,Shanghai Municipal Engineering Institute linked the actual cases of tunnel,the common road surface concrete construction process was changed,to make road surface concrete leverl degree,rough degree and strength as well as wearproof all reached to the requirements of emergency repair,and finished 2,800m2 road surface repair work.

The development of express hard concrete and its maintenance technology was ordered by Shanghai Construction Commission for Shanghai municipal science project,its successful application made up the cement concrete road surface fast repair technology,which large area application has reached to the world level.

The expressed hard concrete is adoptecd by aluminum sulfate superstrong cement produced by Shanghai Yangjing Cement Application Technology institute,and after test and develop,it formed.It not only has easy construction of common cement,but also make up the short of long time concrete protection of common concrete which affected the city traffic.If large continual casting,after 4 hour could open traffic,(4 hours compression pressure 12.0 Mpa,anti-folding 2.8Mpa),it would not affect the city traffic and key road underground construction.

The exampl approve that using express hard concrete to repair cement concrete road surface,the cost was lower than epoxy concrete and other early strong concrete,it had good economic benefit.Its successful application developed a new gold road for cement concrete reform and application of municipal engineering,and it had wide application future.

上海虹桥国际机场停机坪混凝土修补讲演

Report for Concrete Repair of Shanghai Hongqiao Airport Parking Floor

上海虹桥国际机场停机坪运用频次较下,又果年久失修根蒂根基不均匀沉降等诸多身分,已泛起裂痕剥落、露筋等破坏征象,正在混凝土施工缝边沿破坏尤其严峻影响了飞机的一般腾飞和下降,急需加以修补。因为不克不及关闭机场,只能应用深夜飞机停飞的长久工夫停止施工、抢修、因此要求修补的混凝土正在4h后就能供飞机一般运用。便于事情本来没有云云超早强的混凝土手艺,只能用沥青混凝土络续暂时添补,这不仅不克不及彻底解决混凝土破坏题目,并且正在炎天沥青硬化净化了飞机轮胎,以至溅到机身上,同时停机坪及跑道内也随处是玄色的沥青陈迹/这不仅引发了海内航空公司的不满,并且外洋航空公司也有意见。针对这种情况我们应用上陆地泾水泥厂研制消费的硫铝酸盐超早强水泥,停止修补试点工程,而且与得了胜利。在此基础上于1989年7月-10月,应用深夜飞机停飞的6-7小时工夫对混凝土停机坪停止修缮,混凝土修补量约70立方米,修补面积500多平方米,别的借抢修了两块5x5m的大块混凝土。停机坪损坏的混凝土修复,确保了飞机的一般运用。
