Abstract

The invention belongs to a pipe gallery advanced grouting device and method suitable for tree protection. The device is characterized in that a directional grouting pipe is characterized in that a grouting directional plate is arranged on the grouting pipe and is used for limiting grouting liquid in the grouting pipe from structurally diffusing from a grout outlet hole to one side of the groutingpipe, the grouting directional plate is located on the longitudinal outer wall of one side of the grouting pipe, the grout outlet hole is formed in the grouting pipe on the inner side of the groutingorientation plate. The method comprises the following steps that the pH value of soil and the pH value of grouting liquid are obtained according to data and experiments; a proper acid is selected, anda theoretical addition amount is calculated according to a formula; the actual adding proportion of the acid is determined in combination with the field condition; various factors are comprehensivelyconsidered, and the range of grouting pressure is preliminarily determined; the diffusion radius of grouting is determined, and the theoretical grouting amount is calculated; and a grouting test is carried out on site, and proper grouting pressure and grouting amount are determined according to the effect. The method solves the problem of tree protection in underground comprehensive pipe galleryconstruction, and has the advantages of being simple, practical and good in using effect.

Description

technical field [0001] The invention belongs to a device and method for advance grouting of pipe gallery suitable for tree protection. Background technique [0002] The underground comprehensive pipe gallery is a building facility that solves urban ills such as disorderly construction of municipal pipelines, traffic blocking construction, road "zippers", aerial "spider webs", and low utilization of underground space. In order to minimize the impact on the normal life of urban residents, the construction of underground comprehensive pipe corridors mostly adopts the underground excavation method for the construction of underground comprehensive pipe corridors. Well-developed, when pre-grouting for soil reinforcement, it is easy to touch the soil environment for the normal growth of trees, causing the trees to weaken or even die. If the tree is protected by transplanting, it is not only difficult to operate, but also consumes a lot of manpower and material resources, and it wi...
