Construction method for blasting and mud pressing of arc section

Abstract

The invention provides a construction method for blasting and mud pressing of an arc section dyke body. According to the drop bottom width and the mud thickness of the outer side of an arc section, the dyke body is constructed with the same construction footage, parameter design and construction are conducted on the outer side of the arc section according to the throw fill technology that the radian change is gradually reduced along with the throw fill width, and parameter design and construction are conducted on the inner side of the arc section according to the mud thickness and the current construction condition; the construction method specifically comprises the following steps that firstly, parameter design is conducted; secondly, construction is conducted in the pushing direction of a dyke head of a surrounding dyke on the side A; thirdly, construction parameters are rechecked; and fourthly, cyclic construction is conducted till construction of the arc section is finished. The construction method has the beneficial effects that by means of the construction method, construction is relatively convenient, the field throw fill control difficulty is lowered, and the construction safety is high; and the construction overlapping area cannot occur, resource waste is avoided, and the problems that due to stone coverage, the explosive distribution working face is reduced and mud outlets are reduced are solved.

Description

technical field [0001] The invention relates to a construction method for blasting and squeezing silt, in particular to a construction method for blasting and squeezing silt in an arc section. Background technique [0002] The blasting-squeeze soft foundation treatment technology has been widely used in port breakwaters, land reclamation and other projects, and has significant advantages in saving economy and ensuring safety. [0003] With the variability and complexity of the marine foundation environment, blasting and silting of complex foundations will gradually lead the blasting and silting market. At present, the blasting and silting construction method of complex foundations, especially the blasting and silting construction method at the arc section of the embankment, is mainly implemented by the following method: when one end is constructed to the corner position, the construction is suspended inside the axis of the embankment, and the axis of the embankment is used a...

Problems solved by technology

At present, the blasting and silting construction method of complex foundations, especially the blasting and silting construction method at the arc section of the embankment, is mainly implemented by the following method: when one end is constructed to the corner position, the construction is suspended inside the axis of the embankment, and the axis of the embankment is used as the center line. , according to certain throwing filling parameters and blasting parameters, several fan-shaped blasting and silting constructions are carried out on the outer side. However, this method is difficult for throwing and filling construction, and it is difficult to control construction safety and project quality. In view of this, it is urgent to develop a The Construction Method of Improving the Construction Ability of Blasting and Squeezing Silt in Circular Arc Section
