In this paper, the waterlogging damage to the cement concrete pavement is analyzed, effective prevention and control measures are put forward. 关键词:水毁 水泥混凝土 破坏及防治Key words: cement concrete damage and damaged by flood prevention and control 一、概述A, an ov
3、erview of the 水泥混凝土路面受水的侵蚀,在综合因素及环境、气候等影响下基层失稳,产生病害。近几年来,我县、各乡、镇修筑了大量的水泥混凝土路面,毋庸置疑,这对提高我县的公路路面质量,增强公路的抗灾能力,改善公路行车条件,提高客货运输效益均起到了积极的作用。Cement concrete pavement is eroded by water, the comprehensive factors and environment, and climate affect supply instability, produce disease. In recent years, our c
4、ounty, and village, the town built a large number of cement concrete pavement, needless to say, to improve the quality of our county highway pavement, enhance the capacity of highway disaster, improve road traffic conditions, improve the efficiency of the passenger and cargo transportation has playe
5、d a positive role. 但是在重交通荷载、超载、水毁、其它自然环境等诸多外部因素的影响下,近期修建的水泥混凝土路面行车后不久就出现了许多不同程度的病害,导致路面的使用性能迅速下降,严重地影响了车辆快速、安全行驶,而且给养护和维修带来了巨大的压力。通过分析水毁原因,从设计、施工、养护三个环节提出防治办法。But in heavy traffic load, overload, waterlogging and other natural environment under the influence of many external factors, such as, the re
6、cent construction of cement concrete pavement appeared shortly after driving many of the different degree of disease, rapid drops in the performance of pavements, seriously affect the fast, safe driving vehicle, and to the maintenance and maintenance has brought great pressure. Analyzes reason of wa
7、terlogging, in three stages: from the design, construction, maintenance, prevention and control measures are put forward. 二、病害情况极其特点Second, disease is extremely characteristic 现举实例:某一路段全长5.26Km。路面结构为:18cm325水泥混凝土面层,20cm砂砾垫层,30cm土基处理。到目前为止出现路面病害如下:Now for instance: a road about 5.26 Km. 18 cm325 ceme
8、nt concrete pavement, pavement structure as follows: 20 cm gravel cushion, 30 cm soil foundation treatment. Pavement diseases so far are as follows: 1、路面病害特点1, the road surface plant disease characteristics (1)板块连续纵向裂缝较多(1) plate continuous longitudinal cracks (2)板块角隅断裂现象较多,断裂位置接缝材料剥落严重,且积水严重;(2) pl
9、ate corner fracture is more, jointing material peeling off serious fracture, and the water is serious; (3)断板和严重破碎板较多,基本上都是在前两种病害基础上进一步发展而产生;(3) so and more severe crushing plate, are basically in the former two diseases on the basis of the further development and produce; (4)病害严重位置的接茬处沥青面层损坏较严重,由于积水
10、和冻融作用使沥青砼松散。(4) the disease location of summer-planting asphalt layer damage more serious, due to water and asphalt concrete freeze-thaw action. 2、路面病害处治情况对照2, the pavement disease treatment situation (1)对混凝土板块凿除重新修复;(1) plate chisel in addition to the repair of concrete; (2)对裂缝板和板底脱空的板块进行压浆灌缝处治达到规范
11、要求;(2) was carried out on the pavement cracks in the plate and the plate at the end of the plate grouting filling and seaming treatment meet the specification requirements; (3)在板块完好而积水严重位置处设置了横向排水体系。(3) in the plate is in good condition and serious water location set up horizontal drainage system. 3
12、、水毁分析3, the waterlogging analysis 3.1 水泥混凝土路面结构层水的来源3.1 the source of the cement concrete pavement structure layer of water 水毁的防治,必须先了解积水产生原因,切断积水的产生渠道,及时处理、排除积水,增强对水的抵抗力,就能达到防治的目的,混凝土路面结构层水的来源主要有以下几方面:Prevention and control of waterlogging must first understand the causes of water cut of water chan
13、nels, timely treatment, eliminate seeper, enhanced resistance to water, can achieve the purpose of prevention and control, the concrete pavement structure layer of water source has the following several aspects: (1)冬、春季节地下水位升高,路面设计标高较低;(1) the rise of underground water level in winter and spring sea
14、sons, pavement design level is low; (2)路面水从路面“三带”、接缝和裂缝中渗入;(2) the surface water from the three zones, joints and cracks in the infiltration; (3)毛细管中的水位上升或相互连通水膜中水的垂直运动;(3) in the capillary water rise or even the water in the water film vertical movement; (4)路肩、绿化带水的渗入。(4) the road shoulder, green w
15、ater infiltration. 3.2 路面积水原因3.2 the road seeper (1) 非机动车道(1) the non-motor vehicle lanes 施工时,非机动车道横坡控制不好形成反坡;通车后,机动车道沉降量大于非机动车道,导致非机动车道偏高,产生积水。When construction, non-motor vehicle driveways transverse slope control not good form against slope; Opened to traffic, vehicle road subsidence quantity is
16、greater than the non-motor vehicle lanes, lead to non-motor vehicle lanes on the high side, produce water. (2) 接缝渗水(2) joint ooze water (3) 填缝料剥落,导致路面雨水渗入基层。(3) joint sealant spalling, caused the rainwater seeping into the soil. 3.3路面结构层处于水饱和状态,在重载频繁作用下,基层条件恶化3.3 in water saturated state, the paveme
17、nt structure layer under the effect of overloading is frequent, the basic conditions deteriorate 实践和研究表明,路面过早的破坏在很大程度上是由于水渗入路面结构层引起的。水渗入路面结构层,得不到及时有效排除和处理,就会使得路面结构层长期处于水饱和状态,这是引起路面早期破坏的主要原因。Practice and research show that pavement premature failure is largely due to water seeping into the pavement s
18、tructure layer. Water seeping into the pavement structure layer, cant get timely and effective eliminate and handling, will be the pavement structure layer in water saturated condition for a long time, this is a major cause of pavement early damage caused. 受综合因素、环境、气候等的影响,使得混凝土路面基层条件恶化,导致面层唧泥、裂缝、断板、
19、错台、拱起等各种病害的发生,进而造成混凝土路面破坏,失去其应有的功能。Influenced by comprehensive factors, environment, climate, etc., makes concrete pavement base conditions deteriorate, leading to pumping mud on the surface, cracks, so, wrong table, arch, etc. The occurrence of various diseases, causing the concrete pavement damage
20、, lost its due function. 路面结构层长期处于水饱和状态,在重载、水泥混凝土板块收缩应力、翘曲应力等重复作用下,使得路基发生唧泥、冻融现象,路基土不均匀膨胀和沉降,细粒材料的冲刷及流失,导致基层脱空,使混凝土板块支承条件恶化。Pavement structure layer in water saturated condition, for a long time in overloading, cement concrete plates, contraction stress, buckling stress under the action of repeated,
21、 such as pumping mud, freeze-thaw occur makes roadbed, roadbed uneven expansion and subsidence, soil erosion and loss of fine grained material, lead to grassroots escapes, worsen concrete plate support conditions. 4、防治措施4, prevention and control measures 水毁原因特别复杂,要想有效防治,必须从设计、施工、养护三个环节入手,加强重视。Waterl
22、ogging reason extremely complex, to effective prevention and control, must be from the design, construction, maintenance, three links, strengthen the attention. 4.1设计阶段4.1 the design phase 4.1.1横断面4.4.1 cross-sectional 为了保证路面水能够及时排除,横坡以3%为宜,目前横坡设计多为1.5%2%,由于下沉和施工等原因,常出现平坡甚而反坡现象。To ensure the road su
23、rface water in a timely manner to eliminate, transverse slope with 3% advisable, cross slope design is 1.5% 2% more, because the reason such as sinks and construction, often appear flat slope even reverse slope phenomenon. 4.1.2排水体系4.1.2 the drainage system 路面下排水不足是引起路面性能不佳和路面早期破坏的主要原因。所以,设计时应考虑一个合理
