This paper introduces the uses and working principles of TBW250/ 40 mud pump in geological exploration drilling, and in the light of the problems o f the valve base occurring in its application, puts forward a restoring method o f increasing the aperture and then making the inserted cover.

The paper pointed out the reason about the balll machine's shaft running outsaid lane and expounded two restoring methods:restored by traditional machine process and restored by adopting new style mending agent.

Some kinds of condition of IE browsers destabilized by web virus were introduced,and the restoring methods were pointed out.

To explore the principles and techniques of ecological rehabilitation of the rivers,the ecological engineering principle and technology were used to study the rehabilitation methods of damaged riverside plant communities in subtropical waterhead of Tian-xia River.

Because of the local collapse of the 300t mixer receiving iron mouth and a lot of consumption about receiving iron jackets,after analyzing three restoration schemes,the field hot pouring schem is adopted combining the practice production.

Furthermore,the suitability of each repairing method was analyzed.

Based upon introduction of the classification of the cracks of concrete the reasons caused those concrete cracks are analyzed,at the same time corresponding prevention measures and repairing methods are proposed in order to promote the application of measures in practice.

Based on the practice of the treatment of the quality defects occurring on the Precast reinforced concrete members used in some engineering of the Fenghuangshan Coalmine, this paper analyzes on the causes why the fractures occur on the Precast reinforced concrete members, and puts forward some repairing methods, which obtain good results.
