Abstract
The invention provides an H-shaped steel welding template construction device and method for joints of an underground diaphragm wall. The device comprises a platform steel plate, a plurality of supporting steel plates, multiple pairs of herringbone inclined struts and hinges, wherein the platform steel plate provides a mounting platform for the supporting steel plates and the herringbone inclined struts; the plurality of supporting steel plates are parallelly arranged along the length direction of the platform steel plate in an equally spaced manner; the panels of the supporting steel plates are vertical to the plane of the platform steel plate; the long edges of the supporting steel plates are vertical to that of the platform steel plate and are welded to the platform steel plate; the multiple pairs of herringbone inclined struts are symmetrically distributed on two sides of the plurality of supporting steel plates in the length directions separately, and are connected and fixed to the platform steel plate through the hinges. The method is based on the device. According to the device and the method provided by the invention, the H-shaped steel manufacturing process flow is greatly simplified, the production potential safety hazard is reduced, the production efficiency is increased, and the production cost is lowered. The H-shaped steel produced by the device and the method can meet the engineering demand, accords with the demand on construction machinery in construction sites, and has a very good engineering application prospect.
Description
technical field [0001] The invention relates to a construction device and method in the technical field of construction engineering, in particular to a construction device and method of H-shaped steel welding templates for underground diaphragm wall joints. Background technique [0002] Major cities across the country are constructing urban underground rails and various underground space buildings on a large scale, usually requiring excavation of foundation pits. When the excavation depth is large, the surrounding environment of the site is complex, or the reverse construction method is used, it is usually necessary to use the underground diaphragm wall as a temporary structure for retaining soil and water, and it can also be used as a part of the permanent structure of the underground project. There are many types of joints for underground diaphragm walls, including: circular lock pipe joints, corrugated pipe joints, H-shaped steel joints, etc. Among them, the H-shaped ste...
