The ever-changing rules and regulations, teaching systems and teaching methods of world education ensure great changes in the education system.In view of the practical problems existing in the construction of the rule of law culture in colleges and universities, it is necessary to realize the mufti-disciplinary, dimensional and multi-word collaborative innovation of integrating the rule of law culture into the ideological and political education of college students, break the original boundaries and constraints, truly achieve coordinated operation of departmental functions, integrated development of mufti-disciplines and effective participation of social resources, and comprehensively promote the new development of ideological and political education of college students. Under the guidance of collaborative innovation, we should grasp the concrete working logic in the practical construction, and make it clear that the construction of legal culture in colleges and universities is to adhere to the fundamental educational idea of “cultivating people by virtue”, integrate the concept of legal culture into ideological and political education, pursue the value orientation of legal culture, take socialist core values as the logical starting point, realize the main position of education from theoretical level to practical level, and make every effort to build a new pattern of ideological and political education for college students.The results show that: the number of students returning to the dormitory is the highest when the entrance guard is 20:50-21:10, and the lowest when the entrance guard is 17:50-18:20. The percentage of the students returning to the dormitory during the period of 13:40-13:55 is higher than that of the students in the period of 11:50-12:20.

Abstract. The deep foundation pit engineering is a complex system engineering. The supporting structure must be safe and reliable and the costs must be economical and practical in its design process. For coordinating the relationship between them, the optimization design of deep foundation pit supporting engineering is born. As the optimization of deep foundation pit supporting engineering has many difficulties, such as (1) continuous variables and discrete variables coexist in the design variables, variables are numerous, variable combination are large; (2) as the optimization goal and design variables are complex, each design variable on the sensitivity of the optimization goal is not consistent, set up reasonable explicit expression is more each design variable on the sensitivity of the optimization goal is not consistent, establish reasonable explicit expression is difficult, so the traditional optimization algorithm in the face of complex optimization problem of deep foundation pits are often powerless, therefore, to find a reasonable and feasible optimization algorithm is the key. This paper analyzes the reason of foundation pit supporting instability, optimizes the supporting design and puts forward the proposals of corresponding reinforcement.

Abstract. With the continuous expansion of application of the concrete structure materials in construction engineering, different types, different properties of concrete materials also have been developed in application, in which foam concrete is the more representative. Foam concrete is stirred with cement (425 above), fine sand as the base material, adding foaming agent, expansive agent, additives, and even waterproof agent and mixed by special mixer. It has millions of tiny independent. It is uniform distribution with closed pore structure. Light weight, good thermal insulation performance, sound insulation, fire resistance, good pump performance, good water resistance, strong water resistance, strong impact energy absorption performance, and low price. It can be widely used in foamed concrete block, foamed concrete lightweight wall panel, roof thermal insulation making slop, the ground insulation cushion, foundation pit filling, the wall pouring and other projects. This paper expounds the new type of insulation foam material mixed coagulation characteristics and the composition of the material, finally explains the foam concrete construction method and process, which shall be the reference to relevant personage.
