Embodiment Construction

[0042] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0043] Such as figure 1 As shown, the construction method of the corrugated pipe replacing the concrete corridor of the belt conveyor in the gravel system includes the following steps:

[0044] ① Bellows selection: Determine the burial depth of the bellows and the material and size of the bellows according to the stacking height of the silo, and determine the size and material of the bellows;

[0045] ②Construction preparation: Prepare auxiliary equipment such as excavators, loaders, cranes, vibrating mills and welding machines, test materials, construction points and equipment and make records; arrange superfine crushing adjustment silos and corrugated pipes for finished silos according to the design drawings location, the silo is divided into an ultrafine crushing adjustment silo and a finished product silo, wherein the ultrafin...

Abstract

The invention provides a construction method of replacing a sealing-tape machine concrete gallery in a gravel system with a corrugated pipe. The construction method comprises the following steps of construction preparation, ditch excavation, foundation treatment, corrugated pipe assembly, pipeline linear laying, backfill, reinforcement of a discharging opening and a pneumatic segment gate, backfill of pipe body top and load test and completion test. The construction method has enough strength and tenacity, so that certain material accumulation load and foundation settlement deformation can be borne; the assembly construction period is short; the construction method is not limited by climate conditions; prefabricated semi-products produced by factories are assembled on site, so that construction site occupation is small; backfill can be rapidly performed after assembly to form a material bin platform; the construction method is not limited by the coagulation period of concrete; a site can be provided for other operation in advance; operation personnel are fewer; used transfer materials are fewer; construction cost is low; and after construction is finished, the metal corrugated pipe can be recycled for repeated utilization, so that a certain recycle value is provided.

Description

technical field [0001] The invention relates to the technical field of the pipeline industry, in particular to a construction method of a corrugated pipe in a gravel system. Background technique [0002] The project is located in Sangri County, Tibet, and the project area is about 219km away from Lhasa City. The only way to get from the construction site to Lhasa is by road, mainly relying on the new S306 provincial road, which currently has some mud and gravel roads, and the external traffic conditions are poor. The project is located in a plateau area at an altitude of about 3500m, where production and living materials are relatively scarce, and most of the production and living materials need to be transported inland. According to our company's previous construction experience, the key and difficult points of construction in such areas mainly include the guarantee of production and living materials, construction resource allocation, and external coordination to reduce in...
