Embodiment Construction

[0023] First, five concrete blocks of different specifications, a, b, c, d, and e, are manufactured with molds. The concrete block of a specification is a rectangular parallelepiped of length×width×thickness: 1700mm×100mm×100mm; the concrete block of b specification is made in On the basis of the specification a, there is a card slot at the bottom with a length×width×height: 1500mm×100mm×30mm, and a protruding head at each end of the length×width×thickness: 100mm×100mm×30mm; the c-specification concrete block is in b On the basis of the specifications, there is a first length × width × height: 100mm × 50mm × 30mm card slot on the upper end surface 100mm away from the end, and then there are card slots of the same specification every 100mm. 8 pieces, on the basis of specification b, there is a first length x width x height: 100mm x 50mm x 30mm card slot on the upper end of the long side 200mm away from the end, and then every other There are 7 card slots of the same specificati...

Abstract

The invention discloses a method for monitoring the support effect of a self-locking solid wall of a new type of concrete prefabricated block, which belongs to the technical field of support for gob-side entry retaining in mining engineering. The masonry wall is composed of five concrete blocks of different specifications arranged in a reasonable and orderly manner. Through the careful design of the specifications of the concrete blocks and their arrangement sequence, the wall has a self-locking function, which enhances the wall's security. Integrity and ability to resist lateral thrust. From the three aspects of horizontal, vertical and inclination angles, the anti-deformation ability of the wall is observed, and the stress monitoring of different parts of the wall is carried out to analyze the support strength of the wall. Through the statistical analysis of the monitoring data, in order to improve the wall The overall quality provides an important basis.

Description

technical field [0001] The invention relates to the technical field of roadside support for gob-side entry retention in mining engineering, in particular to a method for monitoring the support effect of a self-locking solid wall of a new type of concrete prefabricated block. Background technique [0002] (1) At present, the supporting bodies beside the gob-side entry retaining mainly include concrete pouring solid walls, gangue bag anchor reinforcement walls, concrete prefabricated block hollow walls, concrete prefabricated block solid walls, etc., but basically there are certain defects, and the applicable conditions Limited, difficult to popularize and use. (2) The concrete prefabricated block self-locking solid wall is a new type of wall suitable for the side support of gob-side entry retaining. The factors considered in the design are more comprehensive, so that it has high early strength, good integrity, and lateral resistance. It has the advantages of strong pressure ...
