【摘要】：水电工程进场公路不仅是建设期施工物资(大型施工机械、施工材料等)的运输通道,同时也是地方交通网络的重要组成部分,公路设计等级高,施工质量要求高。路面摊铺厚度是影响进场公路耐久性能的关键因素之一。传统的路面摊铺厚度控制方法主要依靠现场施工人员随机插钢尺的方法进行人工控制,由于受人为因素干扰,难以实现摊铺厚度连续控制,且管理较粗放,往往易于造成摊铺厚度不达标的情况。而拉钢丝线法和架设平衡梁法等常规方法,由于其控制方法自身的弊端,难以保证其路面摊铺厚度控制精度,且不能对施工过程中路面摊铺厚度值进行记录,不利于实现摊铺厚度施工质量精确控制和有效管理,难以确保施工质量。在路面摊铺厚度检测方面,钻孔法和无损检测方法,只能实现路面摊铺厚度事后管理,且均未能提供检测位置的绝对坐标,无法实现路面摊铺厚度现场实时控制及事后检测位置处不合格区域的精确定位。因此,有必要结合水电工程进场公路路面摊铺厚度施工的特点,深入研究进场公路路面摊铺厚度实时监控技术,对于确保水电工程进场公路路面摊铺厚度的施工质量具有重要的现实意义。本文主要研究内容和成果如下:(1)结合全站仪自动跟踪定位技术、Zigbee通讯技术、激光测距技术及GPRS技术等,研制开发了路面高程实时采集装置,提出了路面高程计算方法,实现路面(摊铺基准面和摊铺面)高程值的连续、自动、高精度、实时采集,为路面摊铺厚度的计算提供基本依据。(2)依据路面摊铺基准面采集计算的离散采样点高程值,构建基准面TIN数字高程模型(DEM),提出了基于DEM的路面摊铺厚度(摊铺面与基准面高程差)的实时计算方法,实现了路面摊铺面采样位置处的摊铺厚度的实时计算。(3)研制开发了水电工程进场公路路面摊铺厚度实时监控系统,同时进行了工程初步应用,实现了路面摊铺厚度的实时显示、不达标区域的实时报警,可直观、准确地指示摊铺厚度不合格区域的坐标位置,便于及时指导质量补救,有助于建立路面摊铺厚度前方(摊铺施工仓面监理、施工单位)与后方(现场营地设计、业主等)结合的“司机-承包商-监理-业主”一体化的质量管理模式,有效提高了路面摊铺厚度施工质量的管理水平。
[Abstract]:The approach highway of hydropower project is not only the transportation passage of construction materials (large construction machinery, construction materials, etc.) during the construction period, but also an important part of the local traffic network. The highway design grade is high and the construction quality is high. Pavement paving thickness is one of the key factors affecting the durability of approach highway. The traditional method of pavement paving thickness control mainly relies on the method of randomly inserting steel ruler on site. Because of the interference of human factors, it is difficult to realize the continuous control of paving thickness, and the management is extensive. It is easy to cause the paving thickness to fail to meet the standard. However, the conventional methods, such as drawing wire wire method and erecting balanced beam method, are difficult to ensure the control accuracy of pavement spreading thickness due to the disadvantages of the control method itself, and can not record the pavement paving thickness value during the construction process. It is difficult to ensure the construction quality because it is unfavorable to the accurate control and effective management of the construction quality of the paving thickness. In the area of pavement paving thickness detection, drilling method and nondestructive testing method can only realize the management of pavement paving thickness afterwards, and neither of them can provide the absolute coordinates of the detecting position. It is impossible to realize the real-time control of the pavement paving thickness and the accurate location of the unqualified area in the post-inspection position. Therefore, it is necessary to study the real-time monitoring technology of the pavement paving thickness in the approach highway based on the characteristics of the construction of the pavement paving thickness in the approach road of hydropower project. It has important practical significance to ensure the construction quality of pavement paving thickness of approach highway in hydropower project. The main contents and results of this paper are as follows: (1) combining with the automatic tracking and positioning technology of total station, such as communication technology of Zigbee, laser ranging technology and GPRS technology, the real-time collection device of pavement elevation is developed, and the method of pavement elevation calculation is put forward. To realize the continuous, automatic, high precision and real-time collection of the elevation values of the pavement (paver datum and paving surface), which provide a basic basis for the calculation of the pavement paving thickness, and provide a basic basis for the calculation of the pavement paving thickness) the elevation values of the discrete sampling points collected and calculated according to the pavement paving datum, The TIN digital elevation model of datum level is constructed, and a real-time calculation method of pavement paving thickness (difference between paving surface and datum elevation) based on DEM is proposed. The real-time calculation of the paving thickness at the sampling position of the pavement paving surface is realized. The real-time monitoring system of the pavement paving thickness in the approach road of hydropower project is developed. At the same time, the preliminary application of the project is carried out, and the real-time display of the pavement paving thickness is realized. The real-time alarm of the sub-standard area can intuitively and accurately indicate the coordinate position of the unqualified area of spreading thickness, facilitate timely guiding quality remedy, and help to establish the front of paving thickness (supervision of storehouse surface of paving construction). The quality management mode of "driver, contractor, supervision and owner" integrated with rear area (site camp design, owner, etc.) has effectively improved the quality management level of pavement paving thickness construction.
