【摘要】：水電工程進(jìn)場公路不僅是建設(shè)期施工物資(大型施工機(jī)械、施工材料等)的運(yùn)輸通道,同時(shí)也是地方交通網(wǎng)絡(luò)的重要組成部分,公路設(shè)計(jì)等級(jí)高,施工質(zhì)量要求高。路面攤鋪厚度是影響進(jìn)場公路耐久性能的關(guān)鍵因素之一。傳統(tǒng)的路面攤鋪厚度控制方法主要依靠現(xiàn)場施工人員隨機(jī)插鋼尺的方法進(jìn)行人工控制,由于受人為因素干擾,難以實(shí)現(xiàn)攤鋪厚度連續(xù)控制,且管理較粗放,往往易于造成攤鋪厚度不達(dá)標(biāo)的情況。而拉鋼絲線法和架設(shè)平衡梁法等常規(guī)方法,由于其控制方法自身的弊端,難以保證其路面攤鋪厚度控制精度,且不能對(duì)施工過程中路面攤鋪厚度值進(jìn)行記錄,不利于實(shí)現(xiàn)攤鋪厚度施工質(zhì)量精確控制和有效管理,難以確保施工質(zhì)量。在路面攤鋪厚度檢測方面,鉆孔法和無損檢測方法,只能實(shí)現(xiàn)路面攤鋪厚度事后管理,且均未能提供檢測位置的絕對(duì)坐標(biāo),無法實(shí)現(xiàn)路面攤鋪厚度現(xiàn)場實(shí)時(shí)控制及事后檢測位置處不合格區(qū)域的精確定位。因此,有必要結(jié)合水電工程進(jìn)場公路路面攤鋪厚度施工的特點(diǎn),深入研究進(jìn)場公路路面攤鋪厚度實(shí)時(shí)監(jiān)控技術(shù),對(duì)于確保水電工程進(jìn)場公路路面攤鋪厚度的施工質(zhì)量具有重要的現(xiàn)實(shí)意義。本文主要研究內(nèi)容和成果如下:(1)結(jié)合全站儀自動(dòng)跟蹤定位技術(shù)、Zigbee通訊技術(shù)、激光測距技術(shù)及GPRS技術(shù)等,研制開發(fā)了路面高程實(shí)時(shí)采集裝置,提出了路面高程計(jì)算方法,實(shí)現(xiàn)路面(攤鋪基準(zhǔn)面和攤鋪面)高程值的連續(xù)、自動(dòng)、高精度、實(shí)時(shí)采集,為路面攤鋪厚度的計(jì)算提供基本依據(jù)。(2)依據(jù)路面攤鋪基準(zhǔn)面采集計(jì)算的離散采樣點(diǎn)高程值,構(gòu)建基準(zhǔn)面TIN數(shù)字高程模型(DEM),提出了基于DEM的路面攤鋪厚度(攤鋪面與基準(zhǔn)面高程差)的實(shí)時(shí)計(jì)算方法,實(shí)現(xiàn)了路面攤鋪面采樣位置處的攤鋪厚度的實(shí)時(shí)計(jì)算。(3)研制開發(fā)了水電工程進(jìn)場公路路面攤鋪厚度實(shí)時(shí)監(jiān)控系統(tǒng),同時(shí)進(jìn)行了工程初步應(yīng)用,實(shí)現(xiàn)了路面攤鋪厚度的實(shí)時(shí)顯示、不達(dá)標(biāo)區(qū)域的實(shí)時(shí)報(bào)警,可直觀、準(zhǔn)確地指示攤鋪厚度不合格區(qū)域的坐標(biāo)位置,便于及時(shí)指導(dǎo)質(zhì)量補(bǔ)救,有助于建立路面攤鋪厚度前方(攤鋪施工倉面監(jiān)理、施工單位)與后方(現(xiàn)場營地設(shè)計(jì)、業(yè)主等)結(jié)合的“司機(jī)-承包商-監(jiān)理-業(yè)主”一體化的質(zhì)量管理模式,有效提高了路面攤鋪厚度施工質(zhì)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.
