Control method of equipment for integrally forming internal and external arc-shaped corners of foundation pit and foundation trench

Abstract

According to the control method of the integrated forming foundation pit foundation trench internal and external arc angle equipment, a controller is electrically connected with a front drive motor, a middle drive motor, a rear drive motor and an infrared sensor, the length of a circular track corner section is recorded into the controller in advance, a stepping motor is adopted as the middle drive motor, and the step length of the stepping motor is consistent with the length of the circular track corner section; an internal corner driving system of the arc-shaped internal corner forming equipment and an external corner driving system of the arc-shaped external corner forming equipment are staggered from each other, and an infrared sensor emits infrared rays to irradiate a photosensitive plate, so that the internal corner driving system and the external corner driving system keep running in tandem; concrete slurry overflowing from the external corner mold falls to the right-angle internal corner of the foundation trench and is coated on the right-angle internal corner by the following internal corner mold, so that an arc-shaped internal corner formed by the internal corner mold cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of foundation groove forming equipment control, and relates to a control method for integrated forming foundation pit foundation groove yin and yang arc angle equipment. Background technique [0002] In the construction of super-large foundation pit engineering, there are many construction units, which are formed after vertical excavation from the ground surface. In order to solve the problem of water seepage in the foundation pit, it is usually necessary to excavate the foundation trench in the foundation pit, that is, the foundation trench The depth of the foundation pit is deeper than that of the foundation pit. By introducing the permeable water into the foundation pit and draining the outside, after the foundation treatment of the foundation pit and foundation pit, it is also necessary to carry out waterproof treatment to avoid surface water reverse seepage and later foundation pit storage. Water penetr...

Problems solved by technology

[0003] Therefore, it is also necessary to carry out multi-layer waterproof treatment on the foundation pit and foundation trench, such as sticking adhesive waterproof membranes in the foundation trench and on the surface of the foundation pit to improve the waterproof penetration performance; The material has a certain thickness, and there are right-angled internal angles and right-angled external angles at the bottom of the foundation groove, the joint between the foundation pit surface and the foundation groove, which makes it easy to hollow out when the coiled material is attached, resulting in a decrease in waterproof performance. In order to solve this problem, a This kind of molding equipment is used to process the right-angle internal angle and the right-angle external angle. However, this equipment is divided into internal angle processing equipment and external angle processing equipment. The two operate independently during operation, resulting in the right-angle internal angle and the right-angle external angle in the same base groove. The right-angle male angles on the surface of the base groove cannot be coordinated with each other, and there is an advanced operation or a lag operation. For example, the male angle processing equipment is located above the female angle processing equipment. If the male angle processing equipment lags behind, or the female angle processing equipment is ahead, it will lead to confusion When the mud slurry underflows, it will cause damage to the treated curved inner corner, and the forming part needs to be reprocessed
