Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building grouting, in particular to a steel pipe pile grouting sealing cover with a pressure gauge. Background Art
[0002] In municipal foundation pit support projects, steel pipe piles are widely used, but their support effect depends largely on the quality of grouting. Traditional grouting methods have many limitations, which not only affect the progress of the project, but also may cause hidden dangers to the safety of the project.
[0003] First, traditional grouting methods often rely on workers' experience and feelings to control grouting pressure, which lacks precision and easily leads to unstable grouting pressure. Excessive pressure may damage the soil around the pile and affect the stability of the foundation pit; while too little pressure may lead to insufficient grouting, voids inside the pile, and reduced support strength.
[0004] Secondly, due to the inability to accurately monitor the pressure changes during the grouting process, it is difficult to ensure the uniformity and fullness of the grouting with traditional methods. This may lead to uneven distribution of grout inside the steel pipe pile, forming local weak points, thus affecting the overall support effect.
[0005] In addition, it is difficult to visually inspect and evaluate the grouting effect after the traditional grouting method is completed. In this case, once the grouting is not full or has defects, it is difficult to detect and correct them in time, which may bring safety hazards in the subsequent construction process.
[0006] In view of the above problems, the steel pipe pile grouting cap with pressure gauge developed by us is particularly important. It effectively solves the problems of inaccurate pressure control and difficult to ensure grouting effect in traditional methods, and greatly improves the quality and safety of municipal foundation pit support projects. Utility Model Content

[0008] The technical solution adopted by the utility model is: a steel pipe pile grouting sealing cover with a pressure gauge, comprising a steel pipe pile, wherein the steel pipe pile is in the middle of the slope soil, a sealing cover is threadedly installed on the top of the steel pipe pile, a grouting port is penetrated through the middle of the sealing cover, a grouting pipe is inserted in the grouting port, a sealing cover is installed between the grouting pipe and the grouting port, a pressure gauge is installed on the upper side of the grouting pipe, and a valve is fixedly installed on the outer side of the grouting pipe.
[0009] As a further improvement of the utility model, a plurality of slurry outlets are evenly opened on the outer side of the steel pipe pile.
[0010] As a further improvement of the utility model, a pressure relief valve is installed on the upper side of the sealing cover.
[0011] As a further improvement of the utility model, an observation port is installed on one side of the pressure relief valve.
