To meet the ever-growing needs for the new material of wall-hollow bricks,block forming machine automation needs to be improved.

Based on the vibration forming principle and vibration forms of block forming machine,this paper mainly illustrated the effect of vibration on block compactness through studying vibratory directions,frequency,amplitude,acceleration and vibration energy.

An electro-hydraulic proportional control system is designed for the block forming machine in this paper.

The Design for U Type Concrete Block Forming Machine and the Study about Its Automatic Control System;

The theoretical design of vibratory parameters of concrete block forming machine was introduced,and some computing formula related to vibratory parameters was deduced,the experimental results show the mothed is feasible.

Based on concrete block forming machine vibration mechanical model and kinematic equation, and improved, vibration testing method is proposed develop the concrete block forming machine vibration test system with virtual instrument technology combined with PC-DAQ scheme.

A main way of block forming is that concrete mix aggregate in the shape box and shape by vibration and pressure.

Owing to the crack problem of concrete small block, various preventions from the material, design and construction.

According to the construction quality checking and accepting gauge of GB 50203-2002 bricking-up project,it puts forward the specific construction technique requests to the quality control of concrete small block bricking-up,to prevent the generation of construction quality technique problems and assure the construction quality of concrete small block bricking-up.
