           随着磐安县城市建设的日益发展，高层建筑不断涌现，大体积浇注工程、城市道路建设等日益增多，大跨度、大体积混凝土的构件也被大量采用，为了能保证混凝土质量、降低能耗、减少施工占地，减少噪音，美化环境，满足施工需要，排污泵我县城市建设也与去年开始，分别从东阳、浦江、义乌等地采购商品泵送混凝土到建设工地使用。

    今年6月我县也成立了泵送混凝土搅拌站，并开始试营运，部分建筑工地已在使用了此类商品泵送混凝土。但目前市场抽查发现，主要存在有的泵送混凝土强度不符合质量标准，多级泵施工方法不正确，养护不到位等问题，造成建筑结构表面经常出现干缩和温度裂缝等现象。因此，如何规范我县商品泵送混凝土市场迫在眉睫，笔者建议可从以下隔膜泵几方面加以严格控制：

    一是严格要求各建筑工地使用有商品混凝土生产资质证书和经营许可证等企业生产的商品泵送混凝土。泵送混凝土质量是否符合国这《钢筋砼工程施工及验收规范》(GBJ204-83)是保证建筑结构质量和安全的前提，因此应该及时取缔无证、无资质生产企业，净化商品泵送混凝土市场，保证泵送混凝土生产质量。

    二是严格要求项目部编制切实可行的泵送混凝土施工方案。泵送混凝土正式浇注前，项目部应事先编制切实可行的泵送商品混凝土施工方案，自吸泵明确混凝土泵送、浇注、振捣、养护、试块留置、拆模和施工缝留设位置和处理，混凝土降温和保温等施工质量保证措施，报公司技术质安科审批后，提交建设、监理确认方可进行施工。磁力泵对大体积混凝土夏季施工及混凝土冬期施工时混凝土在拌制、运输、卸料前的质量保证措施，需方可要求提供书面的降温(夏季)和保温措施，以便对进场混凝土进行监督检查。

    加强监督管理，确保施工方案符合国家《混凝土泵送施工技术规程》(JGJ/T10-1995) 三是严格控制浇注现场泵送混凝土施工管理和现场操作质量控制。泵送施工有不同于普通混凝土施工的规律和特点，施工质量直接影响混凝土结构安全，所以应采取有针对性的施工组织措施，在交接卸料现场需进行检验确认，在施工中严格加强施工管理和现场操作质量控制，确保泵送混凝土结构的施工质量。

        With Pan'an growing urban construction, high-rise buildings continue to emerge, a large volume casting projects, increasing urban road construction, large span, mass concrete structures are also widely used, in order to ensure that concrete quality, reduce energy consumption, reduce the construction land, reducing noise, landscaping, construction to meet the needs of urban construction in the county and last year, respectively, from Dongyang, Pujiang, Yiwu to purchase goods such as pumping concrete to construction sites to use. In June this year, the county has set up a pumping concrete mixing station, and started trial operation, part of the construction sites of such products already in use pumping concrete. However, Multi-stage pumpsthe market spot checks found that there is some major strength of the concrete pumping does not meet quality standards, construction methods are not correct, conservation issues are not in place, resulting in structures on the surface of the phenomenon of shrinkage and temperature cracks. Therefore, how to regulate county pumping concrete products market around the corner, I propose the following aspects can be strictly controlled: First, the various construction sites have strict commercial concrete production qualification certificate andSweage pumps &Sludge pumps business license production of goods such as pumping concrete. Concrete Pumping whether the country that "reinforced concrete construction and acceptance" (GBJ204-83) is to ensure the quality and safety of structural prerequisite, it should be promptly banned undocumented, non-qualified manufacturers, pumping Pneumatic and electric diaphragm pumpsconcrete cleaning products market to ensure production quality concrete pumping. Second, the project prepared by the Department demanding practical pump concrete construction program. Official pouring concrete pumping before the project department should be prepared in advance a practical program of premixed concrete, clear concrete pumping, pouring, vibration, maintenance, retention test block, form removal and location of construction joints and process design, concrete cooling and insulation, such as construction quality assurance measures, reported the company technical quality Anke approval, submit construction, construction supervisionSlurry pumps to confirm before proceeding. Summer Construction on the massive concrete and concrete construction in winter when the concrete in the mixing, transportation, quality assurance measures prior to discharge, be requested in writing before the cooling (summer) and insulation measures in order to supervise and inspect the concrete approach. Strengthen supervision and management, to ensure the construction program in line with national "Concrete Pumping Technical Specification" (JGJ/T10-1995) Third, strictly control the pouringOther pumps of concrete pumping site construction management and quality control of field operations. Pumping concrete construction are different from the ordinary rules and characteristics, construction quality directly affect the safety of concrete structures, it should be targeted to the construction of organizational measures, the transfer of discharging the scene for validation, strictly enforced in construction project management and quality control of field operations, to ensure the construction quality of concrete pumping.
