The confirmation of the engineering quality supervision commitments is the sign that specific responsibilities and primary organizations is carried out in construction engineering quality (security).
The supervision scheme in construction engineering quality (security) should have standardized format and content requirements, including the basic situation of the engineering, the main contents of selective examination in construction engineering quality (security), relevant formalities selective examination, engineering entity quality audit, quality control in important parts etc [8].
The construction bodies’ quality behaviors are the key and focal point of supervision in construction engineering quality (security).
Hence, listening to the construction bodies’ report on spot is key link to carry out supervision in construction engineering quality (security) effectively [11].

Information management system Basic structure of information management system Information management system of TBM construction is composed of 8 parts: system display interface, engineering progress, cutting wheel, screw conveyor, time statistics, materials consumption, single-ring and multiple-rings.
Among them, system display interface, engineering progress, cutting wheel and screw conveyor belong to display interface, the major functions are to display various parameters, engineering progress and the relationship between engineering progress and significant risk evaluation engineering.
So, information management system is developed mainly to propose a tool or method for user to monitoring the whole process of TBM tunneling and achieving risk prediction and management through the analysis of key parameters and the statistics of main materials.
l The system can display engineering progress and analyze risk management information timely, it also provides convenient for the users to analyze the distribution situations and mechanical mechanism of major risk engineering, and proposes the keys in management and controls.
l The system can make detail statistical analysis on consumed materials during TBM construction, concluding tail grease, foam volume and grouting quantity, then construction quality and cost can also be controlled.

A Brief Analysis on the Design of Polystyrene Composite Thermal Insulation Material in Terms of Thermal Characteristics Wang Chao1, a, Yin Zhonghai 2,b and Chen Xuejun 3,c 1 Architecture and Material Engineering Department, Hubei University of Education, China 2 Architecture and Material Engineering Department, Hubei University of Education, China 3 School of Materials Science and Engineering, Wuhan University of Technology, China aemail: wcrcr@163.com bemail: sunyq_95508@163.com cemail: chen1964@163.com Key words: Thermal characteristics; Polystyrene composite thermal insulation material; Heat transfer coefficient; Design Abstract: In the field of architecture, “energy-saving building” has been mentioned as a strategy which is as important as the ones of our population, resources, environment and sustainable development.
The design of the building wall materials in the building envelope is the key step of the wall insulation, which can be taken as the key technology in building energy efficiency.
Thus the thermal resistance of composite materials is increased

Research On Model of Division of Tender of Engineering: A Minimization Cost Perspective Ling Yan1, a, Qiong Sun 2, b 1, 2 Management School, Tianjin University Of Technology, Tianjin,300384,China b tutsuniqong@126.com Keywords: Tenders Division; Engineering Projects ;Engineering Cost; Model Abstract.
Besides engineering cost, Li Qingmei [1]holds the perspective of tenders division is also one of the key factors to the quality and duration of the engineering.
What’s worse, the method has a bad influence on the whole engineering.
What’s more , tenders division affects the costs of engineering.
Source: drawing according to the research Regard to production costs, to contractors, tenders division has influence on the allocation of construction labor, the materials and machinery and equipment investment and other factors.

So the design innovation would focus on the thinness with low cost key components. size target is 98x44x10mm, for others key specifications, it was required to have the functions of blue tooth, VGA camera, 128x160 TFT display and MP3 ringing tones.
Light guide was used to keep the key lighting in dark environment, here a new technology was used for part of light guide, it used silicon material with special guiding method, thickness is just 0.2mm, it contributes a lot for product thickness.
Key components list Key components Specification Engine GSMCost3.01 w/ UPP8Mv6.x.
for covers and related parts design, design for manufacture is one of the most important items considered by engineer.
Figure 4 shows the simulation status in the face down dropping situation, the result conclusion is, the crack risk of LCD glass is low, the front cover, back cover and battery cover have plastic deformation at some local areas, especially front cover, since its material is relatively soft, it used PC resin, back cover used PA resin and battery cover used metal material.

In the teaching reform including investigative study and the integration of information technology, is generally accepted that the integration of information technology with curriculum strategy are: optimizing the course structure of space and time, innovation course materials, course materials bag is mainly composed of electronic schoolbag, local curriculum material storage, remote material storage and teaching platform.
And based on the supporting materials, many schools draw lessons from foreign experience, to fixed teaching material in the form of notes, reduce practice principle part, don't write practical steps, mainly is the question for higher College of Engineering students to solve.
Open practice teaching emphasizes the subjectivity of the engineering students in higher College of Engineering, thus more conducive to excavate the potential of engineering students in higher College of Engineering to meet the psychological needs of engineering students in College of Engineering.
The correct way to learn is to make higher College of Engineering students "creation", also is the engineering students in College of Engineering I have to learn the knowledge discover or created.
Emotions in the field of practice teaching goal: higher College of Engineering students in practice attitude, interests, habits; Higher College of Engineering students and teachers, the engineering students in College of Engineering and emotional communication between engineering students in higher College of Engineering: the cultivation of the scientific spirit, etc. all belong to feelings.

In order to make ensure that concrete has good anti-cracking property, volume stability and impermeability, three points of concrete's mix proportion design should be paid attention to: To use cementitious material system with low heat of hydration.
Besides, it should pay attention to key indexes such as the proportion of water quantity, degree of fineness and loss on ignition.
Thus, it is an important work and a key technique of controlling bulky concrete's quality to study how to control bulky concrete cracks.
