Hollow slab beam end plugging process
The invention relates to a hollow slab beam end plugging process. The hollow slab beam end plugging process comprises the following specific steps that drilling is conducted, specifically, construction holes are drilled in a hollow slab beam; construction equipment extends into the construction holes, plugging materials are sprayed to the two ends of the hollow slab beam through the construction equipment, and the foaming materials are foamed to form plugging layers; a water inlet pipe is inserted into one construction hole, a water drainage pipe is inserted into the other construction hole, water is injected into a cavity of the hollow slab beam along the water inlet pipe, and water inflow is stopped when water flows out of the water drainage pipe; inspecting: observing the water leakage condition of the end part of the hollow slab beam; if the hollow slab beam plug does not leak water, the plug is plugged successfully, and construction is completed; and if the plug leaks water, the steps of'cavity filling 'and'water injection' are repeated until the end part of the hollow slab beam does not leak water, and the construction is finished. The method has the beneficial effects that the plugging material is sprayed to the end of the hollow slab beam, corrosive media such as water can be prevented from entering an inner cavity of the hollow slab beam, and the durability and safety of the hollow slab beam are improved.
本申请涉及一种空心板梁端部封堵工艺，其具体步骤如下：钻孔：在空心板梁上钻施工孔；补腔：将施工设备伸入施工孔中，利用施工设备将封堵材料分别喷在空心板梁的两端，发泡材料发泡形成封堵层；注水：将进水管插入其中一个施工孔中，排水管插入另一个施工孔，将水沿着进水管注入空心板梁的空腔中，待排水管出水，停止进水；检验：观测空心板梁端部漏水情况；若空心板梁堵头无漏水情况，则堵头封堵成功，施工完毕；若堵头漏水，则重复“补腔”和“注水”步骤，直至空心板梁端部不漏水为止，施工结束。本申请具有效果在于：将封堵材料喷在空心板梁的端部，能够阻止水等腐蚀性介质进入空心板梁内部空腔，提高了空心板梁的耐久性和安全性。
