【摘要】：原位澆筑法非開挖修復(fù)(CITR)技術(shù)相比其它非開挖修復(fù)技術(shù)應(yīng)用更靈活、不受結(jié)構(gòu)斷面形式、類型等限制,可用于各類排水管道、檢查井的修復(fù);在大型管涵、隧洞、地下硐室等構(gòu)筑物修復(fù)、加固領(lǐng)域也有廣闊的應(yīng)用前景。本文對(duì)CITR技術(shù)應(yīng)用于地下排水管道設(shè)施修復(fù)的相關(guān)材料、技術(shù)工藝及相關(guān)理論進(jìn)行了系統(tǒng)深入研究,豐富了現(xiàn)有非開挖修復(fù)技術(shù)體系。1.對(duì)地下管道現(xiàn)狀及國(guó)內(nèi)外管道常用非開挖修復(fù)技術(shù)研究和應(yīng)用現(xiàn)狀做了簡(jiǎn)要分析,首次提出了原位澆筑法非開挖修復(fù)(CITR)技術(shù)概念,并對(duì)CITR技術(shù)原理做了詳細(xì)介紹。2.開展了CITR技術(shù)用高性能復(fù)合砂漿材料的試驗(yàn)研究。研究表明,增大基體表面的粗糙度可大幅提升內(nèi)襯砂漿與基體的粘接強(qiáng)度,同時(shí)有利于提高內(nèi)襯修復(fù)效果;抗拉增強(qiáng)材料可提高HPM內(nèi)襯的抗折強(qiáng)度,但對(duì)弧形板的抗折強(qiáng)度的增強(qiáng)效果遠(yuǎn)小于平板;添加抗拉增強(qiáng)材料的試塊抗折破壞特征與增強(qiáng)材料拉伸破壞特征類似,試塊中分開布置多層相同的增強(qiáng)材料的增強(qiáng)效果與單獨(dú)布置一層相當(dāng)。3.開展了圓形管道CITR技術(shù)(簡(jiǎn)稱:管盾技術(shù))的相關(guān)理論和實(shí)踐研究,對(duì)管盾技術(shù)工藝特點(diǎn)、適用條件等進(jìn)行了介紹;并針對(duì)舊管道的不同受力狀態(tài),提出了內(nèi)襯設(shè)計(jì)的基本原則,并建立了內(nèi)襯設(shè)計(jì)理論模型;通過對(duì)DN2,000塌陷管道修復(fù)工程的實(shí)施和總結(jié),驗(yàn)證了管盾技術(shù)工藝可操作性和相關(guān)理論可行性。4.開展了矩形管道CITR技術(shù)的理論和實(shí)踐研究,結(jié)合矩形管道受力及破壞規(guī)律,確定了矩形管道以半結(jié)構(gòu)性修復(fù)為主的基本原則,提出以“閉合剛架”模型做為矩形管盾的理論模型。詳細(xì)介紹了矩形管道CITR修復(fù)過程和內(nèi)襯設(shè)計(jì)的計(jì)算流程,并將技術(shù)和理論應(yīng)用到了矩形排水管道修復(fù)工程中。5.對(duì)傳統(tǒng)檢查井修復(fù)技術(shù)做了詳細(xì)介紹,并對(duì)檢查井的破壞規(guī)律進(jìn)行了系統(tǒng)研究。開展了檢查井離心澆筑修復(fù)技術(shù)(井盾)工藝和理論研究,建立了檢查井內(nèi)襯受力模型,推導(dǎo)并確立了井盾內(nèi)襯的理論計(jì)算模型,井盾技術(shù)及相關(guān)理論已經(jīng)用在500余口檢查井修復(fù)工程中;最后對(duì)全文做了總結(jié)和展望。
[Abstract]:CITR (in situ pouring method) is more flexible than other non-excavated restoration techniques, and can be used in various drainage pipes and inspection wells, and can be used in large pipe culvert, tunnel, etc. The restoration and reinforcement of structures such as underground chambers also have a broad application prospect. In this paper, the related materials, techniques and related theories of CITR technology applied to the repair of underground drainage pipeline facilities are systematically and deeply studied. It enriches the existing technology system of trenchless repair. 1. The present situation of underground pipeline and the research and application of non-excavated repair technology in domestic and overseas are briefly analyzed, and the concept of CITR technology of in-situ pouring method is put forward for the first time. The principle of CITR technology is introduced in detail. 2. The experimental study of high performance composite mortar used in CITR technology is carried out. The results show that increasing the roughness of the matrix surface can greatly improve the bonding strength between the inner lining mortar and the matrix. The tensile reinforcing material can improve the flexural strength of HPM liner, but the strengthening effect of arc plate is much less than that of flat plate. The flexural failure characteristics of the specimens with tensile reinforcement are similar to those of tensile strength. The reinforcement effect of the same reinforcement material arranged separately in the test block is equivalent to that of the single layer. 3. The theoretical and practical research on circular pipe CITR technology is carried out, and the technical characteristics of the tube shield technology are discussed. The applicable conditions are introduced, and the basic principles of lining design are put forward, and the theoretical model of lining design is established according to the different stress states of old pipelines. The feasibility and feasibility of tube shield technology are verified. (4) the theoretical and practical research of rectangular pipe CITR technology is carried out. Combining with the stress and failure law of rectangular pipeline, the basic principle of semi-structural repair of rectangular pipeline is determined. This paper presents a theoretical model of rectangular tube shield based on "closed frame" model. The CITR repair process of rectangular pipe and the calculation flow of lining design are introduced in detail. The technology and theory are applied to the repairing project of rectangular drainage pipeline. The traditional well repair technology is introduced in detail. The damage law of inspection well is systematically studied. The technology and theory of centrifugal pouring and repairing (well shield) are studied, the stress model of inspection well lining is established, and the theoretical calculation model of well shield lining is deduced and established. Well shield technology and related theories have been used in more than 500 inspection well restoration projects. Finally, the full text is summarized and prospected.
