The transient electromagnetic thchniques can be used to determine the key region for grouting reconstruction , guiding the drill hole layout and detect the grouting effect 利用瞬變電磁技術(shù)探測(cè)煤層底板含水層的賦水性特征,確定工作面內(nèi)注漿改造重點(diǎn)區(qū)域,指導(dǎo)鉆孔布置,并在底板改造后檢驗(yàn)注漿改造效果。
Based on this theory , outdoor experiment has obtained good results . a large amount of experimental data about pressure and displacement show that the soil - pressure ' s distribution and the grout effect accord with theory on the whole 按照理論計(jì)算的思路進(jìn)行室外現(xiàn)場(chǎng)試驗(yàn),取得了良好的效果,試驗(yàn)的壓力、位移數(shù)據(jù)表明,壓力分布與位移效果基本上與理論研究相一致。
During the past ten years , many kinds of synthesized acoustic detection methods have been the effective measures for detecting grouting effect , but it is not easy to decide whether the separate detecting result estimation about multifold methods meets the requirements of design standards or not 近十年來(lái),多種方法的綜合聲波測(cè)試已成為灌漿效果檢測(cè)的有效手段之一,但對(duì)多種方法檢測(cè)結(jié)果分別評(píng)判是否達(dá)到設(shè)計(jì)標(biāo)準(zhǔn)難下定論。
This paper introduces the applicability and grouting effect of the single cement slurry , double grout ( cement slurry water glass slurry ) and the fine cement slurry under different condition with an example of gele mountain , and puts forward that for the curtain grouting of karst tunnel the priority is given to improved single cement slurry 摘要通過(guò)歌樂(lè)山隧道帷幕注漿工程實(shí)例,介紹單液水泥漿、雙液漿(水泥水玻璃槳) 、超細(xì)水泥類(lèi)漿液在不同注漿條件下的適用性和注漿效果,提出巖溶隧道帷幕注漿材料的選擇應(yīng)以改良的單液水泥漿為主要材料,其它材料作為補(bǔ)充。
By integrating with the engineering practice of curtain grouting on the right abutment of houhe reservoir and on the basis of field tests , researches were conducted on the establishment of grouting parameters and gins , mix proportion of stable mortar as well as finishing standard of different gins under certain geological condition . and after checking the grouting effects , comparison was made between gin grouting and the traditional grouting technique 本課題結(jié)合后河水庫(kù)右壩肩帷幕灌漿的工程實(shí)踐,通過(guò)現(xiàn)場(chǎng)試驗(yàn)研究,就gin法灌漿在特定地質(zhì)條件下灌漿參數(shù)及gin值的確定,穩(wěn)定漿液的配方,不同gin值的灌漿結(jié)束標(biāo)準(zhǔn)等進(jìn)行了試驗(yàn)研究,并在對(duì)其灌漿效果加以檢查的基礎(chǔ)上,與傳統(tǒng)灌漿工藝進(jìn)行了對(duì)比分析。
