Embodiment Construction

[0024] S1. Before construction, a professional monitoring team is required to conduct geological surveys at the location to be constructed, to find out the geotechnical engineering conditions of the site, and to provide geotechnical engineering basis for the foundation design and construction of the proposed building;

[0025] S2. After the geological survey is completed, it is necessary to analyze the survey results and calculate a reasonable construction plan, supplement or clarify the basic information of each construction location of the main project; improve the foundation depth of the main structure, the depth of the pit in the pit, and the enclosure The influence of the pit within the pit should be considered in the calculation; the specifications and distribution information of underground pipelines around the pit should be supplemented, and the general plan of the foundation pit should be improved;

[0026] S3, according to the general diagram of the foundation pit m...

Abstract

The invention relates to the technical field of earthwork construction, and discloses a water jetting method earthwork excavation construction method. The water jetting method earthwork excavation construction method comprises the following steps that S1, before construction, a professional monitoring team needs to go to a to-be-constructed position to carry out geological investigation, site geotechnical engineering conditions are found out, and a geotechnical engineering basis is provided for foundation design and construction of a proposed building. According to the method, perfect investigation can be carried out before construction, the occurrence of construction accidents during construction can be prevented, and reasonable design is carried out according to the local geology and water quality so as to ensure the construction safety and the service life of a project; the construction method of the water jetting method has the advantages of high efficiency, low cost, good engineering quality, no weather influence on construction and the like; and construction groove inspection and observation monitoring work is enhanced, special observation points are arranged for monitoring and measurement, networked, intelligent and informatization management is formed, problems occurring in the construction process can be fed back in time, and construction safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of earthwork construction, in particular to a water flushing earthwork excavation construction method. Background technique [0002] Under normal circumstances, excavation of excavation of excavation of foundation pit of building and structure engineering is carried out manually, mechanically or manually with machinery. If there is an open and unused site around which can be used as a spoil ground for earthwork excavation and there are ditches and ponds nearby, river water can be used for water flushing excavation construction. [0003] The water flushing method is a method of simulating the principle of water erosion in nature, and uses the action of hydraulic power to excavate, transport soil, and fill soil construction. The water passes through the high-pressure clean water pump to generate pressure water, and the high-speed water flow is injected through the nozzle of the water gun to remove the mud (san...
