Construction method for preventing leakage of cast-in-place pile and row pile supporting structure
The invention discloses a construction method for preventing leakage of a cast-in-place pile and row pile supporting structure, and relates to the technical field of building construction. The construction method for preventing leakage of the cast-in-place pile and row pile supporting structure comprises the following specific operation steps that before a foundation pit supporting structure is constructed, surveying and paying off are conducted to determine the position of a reinforced concrete cast-in-place pile of the supporting structure, and then the cast-in-place pile is constructed. According to the anti-seepage construction method for the cast-in-place pile row pile supporting structure, when cast-in-place piles are adopted, high-pressure jet grouting is conducted on the outer sides of the cast-in-place piles after the cast-in-place piles are constructed and before earth excavation. The grouting material is injected into a soil body through a high-pressure grouting machine, and the grouting material is diffused towards the surrounding soil body through the grouting holes under the action of high pressure and is solidified so as to fill pores of the soil. Therefore, underground water is prevented from flowing in soil, and the water stopping effect inside and outside the foundation pit is achieved. And after the construction of the cast-in-place pile is completed, the grouting soil body constructed on the outer side of the cast-in-place pile plays a waterproof role, so that leakage of the side wall of the foundation pit is prevented.
本发明公开了一种灌注桩排桩支护结构防渗漏的施工方法，涉及建筑施工技术领域。该灌注桩排桩支护结构防渗漏的施工方法，具体操作如下：施工顺序为基坑支护结构施工前，先测量放线确定好支护结构钢筋混凝土灌注桩位置，接着施工灌注桩。该灌注桩排桩支护结构防渗漏的施工方法，采用灌注桩时，在灌注桩施工后，土方开挖之前，在灌注桩位置的外侧施工高压喷射注浆。将注浆料通过高压注浆机打入土体中，因高压作用，注浆料通过注浆孔向周围土体发散、并凝固，进而填充土壤的孔隙。从而阻止地下水在土壤中流动，达到基坑内外的止水效果。当灌注桩施工完成后，在灌注桩外侧施工完成的注浆土体即起到隔水作用，从而达到防止基坑侧壁渗漏。
