Gate-type pier capping beam construction method
The invention discloses a gate-type pier capping beam construction method which comprises the following steps: S1, bearing platform construction: the excavation depth of a pier bearing platform is less than 4m, the excavation mode comprises slope excavation, in order to ensure that a pipeline is not influenced, the geology is investigated before excavation, and excavation is carried out after the pipeline is moved and changed in place; s2, pier body construction is conducted, specifically, in order to facilitate construction, a safety crawling ladder is erected on the outer side close to the pier body, the ladder cage is firmly connected with a bearing platform face in the erecting process, and the periphery is surrounded by a protective net; and S3, gate-type pier capping beam construction preparation: firstly, during steel pipe column foundation construction, construction measurement is carried out, the position of a steel pipe stand column embedded steel plate is measured, then materials enter the site and are detected to be qualified, machines enter the site and are accepted and accepted, and then it is confirmed that the site has construction conditions. According to the method, the bearing capacity of the support in gate-type pier cover beam construction is effectively improved, meanwhile, tensioning construction of a prestress system is effectively guaranteed, and the stability of the gate-type pier cover beam is improved.
本发明公开了一种门式墩盖梁施工方法，包括如下方法步骤：S1、承台施工：墩承台开挖深度＜4m，开挖方式具备放坡开挖，为确保对管道无影响，开挖前对地质进行调查，确保管线迁改到位后进行开挖；S2、墩身施工：为方便施工，在靠近墩身外侧搭设一道安全爬梯，梯笼搭设过程与承台面连接牢固，外围采用防护网围护；S3、门式墩盖梁施工准备：首先，钢管柱基础施工时，做好施工测量，测定钢管立柱预埋钢板位置，其次材料进场并检测合格，机械进场并验收合格，之后确认现场场地具备施工条件。本发明有效提高了门式墩盖梁施工中支架的承载能力，同时有效的保证预应力体系张拉施工，提高门式墩盖梁的稳定性。
