鉆孔灌注樁在城市建筑和橋梁工程中得到普遍應(yīng)用。但由于其施工工藝的特殊性和復(fù)雜性,施工的全過(guò)程質(zhì)量控制就顯得十分重要。筆者針對(duì)鉆孔灌注樁施工過(guò)程中常見(jiàn)的問(wèn)題,闡述正循環(huán)鉆孔灌注樁施工過(guò)程中質(zhì)量控制要點(diǎn)。
一、施工準(zhǔn)備
1、鉆孔灌注樁施工方案的審核
①根據(jù)設(shè)計(jì)圖紙、地質(zhì)報(bào)告、現(xiàn)行規(guī)范標(biāo)準(zhǔn)以及現(xiàn)場(chǎng)勘查結(jié)果,審查施工方案的編制依據(jù)、施工工藝流程、技術(shù)指標(biāo)、安全措施等內(nèi)容是否符合要求。針對(duì)混凝土初灌量的計(jì)算可參照J(rèn)TJ041-2000(公路工程標(biāo)準(zhǔn))的規(guī)定進(jìn)行復(fù)算。同時(shí)還應(yīng)審查施工方案中處置突發(fā)事件的應(yīng)急預(yù)案是否符合要求。對(duì)于施工方案的審核應(yīng)具有前瞻性,要善于提出問(wèn)題、發(fā)現(xiàn)問(wèn)
Bored in the city and bridge construction projects are universally applied. However, the construction process due to its particularity and complexity of the whole process of construction quality control is very important. I bored the construction process for common problems, described being bored during the construction cycle of Quality Control.
First, construction preparation
1, bored pile construction plan review
① According to design drawings, geological reports, the current specification standards, and site inspection results, review the basis for the preparation of construction programs, construction process, technical specifications, safety, etc are to meet the requirements. The amount of concrete filling for the beginning of the calculation can refer JTJ041-2000 (road engineering standards) the provisions of recalculation. Should also review the construction program to emergencies contingency plan is to meet the requirements. Construction program for the audit should be forward-looking, should be good to ask questions, find Q
