must make punching force caused by reaction of subsoil outside punching section no more than punching ability of concrete at punching section, then it can be ensured that the bearing push-extend reamed itself do not produce punch failure, according to this it can be derived that the check formula which ensure the height of the bearing push-extend reamed, it means the height of the bearing push-extend reamed h should meet the formula as follow: For the bearing push-extend reamed are single slope, For the bearing push-extend reamed are single slope, In short, through the study of this paper, it is determined that the check formula of the height of bearing push-extend reamed and improves research results of the design of the bearing of the Push-extend Multi-under-reamed Pile, and it is put forward that the theoretical basis of engineering practice of the Push-extend Multi-under-reamed Concrete Pour Pile Acknowledgments This work was financially supported by National Natural Science

Natural fibers, such as cotton, coconut, sial, and WH, are sustainable materials for producing lightweight composites [1, 2].
They help reduce the use of synthetic materials and mitigate the greenhouse effect [1, 5].
WH exhibits a rich source of raw materials for this aquatic plant, with the highest percentage of cellulose content, significantly contributing to its enhanced thermal stability and tensile properties.
Materials and Methods Materials The WH plants were collected from a lake in Dong Tang Long, District 9, Ho Chi Minh City, Vietnam, with an approximate 50 cm length.

As people’s living standard’s improving, it becomes common to see obese children, so our kids can play with the swing machine and exercise their bodies to lose weight at the same time. 3 Rapid prototyping manufacturing The first thing we do is materials selecting and production process outputting.
It saves materials and extends the using period as well, which includes the entertainment.
Today’s society promotes energy efficiency, such a material-saving and durable cycle will be the trend.

For the building frame insulation, wool insulation material (Possibility of local industrial development) and EPS panel (Expanded Poly-Styrene) which is popular in China are used, and for the openings, the multi-layer glass is installed.
In addition, the difference in thermal conductivity of the insulating material, the indoor temperature is higher using EPS panel than the wool insulation material.
Residents provide biomass resources which become raw material for methane gas, and the heat is provided by the local methane gas boiler.
Compared to acquisition of raw material for biomass are relatively stable, solar power relies on weather, so it requires the auxiliary heat source for winter heating supply. 5.

Membranes suited for technical applications may be classified by the following characteristics [8-11]: · Membrane materials: Organic polymers, inorganic materials (oxides, ceramics, metals), mixed matrix or composite materials · Membrane cross-section: Isotropic (symmetric), integrally anisotropic (asymmetric), mixed matrix composite · Preparation method: Phase separation (phase inversion) of polymer, sol-gel process, interface reaction, stretching, extrusion, track-etching and micro-fabrication · Membrane shape: Flat sheet, hollow fiber, capillary, tubular and capsule.
Polysulfone (PSf) is an excellent UF membrane material because of its film and membrane forming properties and high mechanical and chemical stability [18].
