Embodiment Construction

[0024] The method for pile bottom grouting proposed by the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0025] The core idea of ​​the present invention is to provide a method for pile bottom grouting, which is used to fill the space left by the pile bottom sediment area of ​​the pile foundation after removing the sediment. The pile bottom grouting method includes step 1: using The grouting pump pours the thick cement slurry into the bottom of the pile through the core hole through the conduit, and replaces all the clear water poured into the sediment area during the ...

Abstract

The invention provides a pile bottom grouting method. Grouting materials are utilized as pile bottom filling replacement materials to replace cement slurries, cement mortars or fine aggregate concretes. Compared with the cement slurries and the cement mortars, the grouting materials are large in vertical expansion ratio and high in strength; compared with the fine aggregate concretes, the grouting materials have pourable construction feasibility inside narrow and small holes; accordingly the grouting materials are capable of saving the grouting amount and grouting time when grouting operation is performed; and the pile bottom grouting efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for pile bottom grouting. Background technique [0002] When performing pile bottom grouting operations, the general grouting method is to pour cement slurry, cement mortar or fine stone concrete into the sediment area at the bottom of the pile to fill the space left by the sediment removal, but due to the cement slurry and The expansion rate of cement mortar is not large, and the fine stone contained in fine stone concrete will also cause the blockage of the conduit, so these three grouting methods will affect the efficiency and quality of grouting work, and the required cement slurry or cement mortar The amount is very large, resulting in increased cost and waste of materials. Contents of the invention [0003] The purpose of the present invention is to provide a method for pile bottom grouting to solve the problems of high cost and low efficiency of grouting op...
