A significant impulse to focus the attention of not only the professional public on the issue of corrosion of steel prestressing ropes, was initiated by the unfortunate collapse of the footbridge in Prague - Troja, connecting the Vltava banks of the “Císařský ostrov” and “Troja”.
In some places, the water penetrating the structure evidently migrated in the core or on the surface of the prestressing rope wires, flowed down by gravity in the direction of the longitudinal slope of the bridge deck and rose by capillary forces in the narrow slots between the rope wires.
The state of humidity and the presence of water in the cavities of the Troja footbridge certainly affected the floods, during which the footbridge twice completely disappeared under the water and withstood the significant load of water-borne objects.
As the small semi-destructive probes showed, water entered the bridge deck, probably in the form of condensate, only through these hollow sections.
The cut heel of the original profile was left in the bridge deck, full of water and moss here The detected content of chloride ions in the concrete of the footbridge is very low and meets the limit required for prestressed structures of 0.2% by weight cement.

The rural environmental pollution is expanding from water-soil pollution to multidimensional-frame pollution.
Popularization of rural afforest is an important part of land greening, and it not only embodies the spiritual outlook of a country, a nation, an area or a countryside, but also is a forward position against desertification, water loss and soil erosion, protection of ecological environment.
Actively propagate of the principles of landscaping in the round, which is that the exposed and idle land is landscaped in the round, is an effective way to prevent water and soil erosion.
The receiver towers for wireless signal should be given regular maintenances by the professional staff to ensure them normal operation.

Key in the pattern to the computer or make a design directly by a designer at the computer, and then go through image processing software or professional color separation system software to process the editing.
Traditional digital inks can be divided into water-based ink and solvent-based ink.
Water-based ink primarily contains active dyes and acidic dyes.
Active dyes possess great water-solubility and color-fixing rates.
Furthermore, disperse dye is solvent ink; its molecular structure is relatively small, and poorly water-soluble, which exists mainly in the fine articles dispersing status in water.

Main architectures such as Dingyuan Department Store, Hawaii Hotel, Changchun Stadium, Water Garden Swimming Center, Zoological and Botanical Gardens, Nanguan City Government, Changchun Public and Security Bureau Nanguan Branch, Jilin Table tennis Training School, Jilin Institute of Physical Education, The Northeast Normal University, The Forestry Hotel and Changchun Mall are located along the road.
Specific advertisements and bill signs should be considered and designed by professional designers to make them a coordinating part of the whole construction and a good way of enriching the textural characteristic of elevations alongside the streets.
For the significant landscape connections, we should increase more detailed decorations. 3.3Change the Flat Roof into Pitch Roof Change the Flat Roof into Pitch RoofMost of the buildings that needed to be modified are flat roof ones, which bring the problem of water leaking for people and greatly influence the quality of living standards.
Solving problems water leaking and improving the problem of warm keeping and heat preventing have become the key issue in the modification.

At European level, there are several professional organizations and bodies that are constantly concerned about food security.
Observations were made on the distortion of the chemical composition of the base material near the welded seam, which led to a decrease in resistance to corrosive factors, both from food materials combined with various substances (salt, preservatives, etc.) and from water and solutions used for sanitation.
The research was carried out using the slam from natural membranes, which circulated through pipes with water recirculation pumps, during the technological process of membrane processing, during a shift, working period of eight hours.
This aspect can raise the question of including the quality of the water with which the sanitation was performed (Figure 3).
This can become alarming for drinking water transmission installations, where the risks are more widespread for all water supply installations in public networks.

Although manual excavated technique has many advantages as stated above, it has some problems when used in Hezhang Bridge site:
(1) Karst water and fissure water is easy to gush;
(2) Soft plastic muddy and sandy fillings make bad influence on the stability of pile hole;
(3) It is impossible to dewater for pile hole digging;
Punching Cast-in-place Pile.
Three approaches were carried out to avoid inclined hole: (a) Backfilling rubble to keep the hammer level; (b) Pouring plain concrete to maintain the hardness consistent; (c) Implementing blasting with explosive under water.
According to the actual project, it often hires the professional divers (at the site it is called ‘water monster’) to dive down into the hole to identify the laying situation of the hammer, and then takes the appropriate measures to deal with it.

This study uses area density as index and excludes sandy area, desert and water area in the measurement so as to guarantee the accuracy of result.
In the rural habitats located near the desert, water is a defining factor in its site selectionand its development.
Most of the habitats were built near water sources, and the water will be supplied and distributed through the digging of irrigation ditches for daily use.
In the rural habitats of Yishikuli, irrigation ditches are rich and the water system is well-developed.

Construction waste has broad, vague and lag features on our lives and the environment, that outstanding perform in the land, air, water, environmental and other impacts.
C.Pollution of Waters.In the process of construction waste pile or landfill, due to fermentation and rain leaching, erosion, and groundwater and surface water’s soak, the leachate is out of sewage, and surface water and groundwater are caused serious pollution.Leachate not only contains a lot of organic pollutants, but also contains a lot of metal and non-metallic contaminants.
Water quality has complex composition, if enters the drinking water source, it will be greatly harm for human bodies.
The British experience can be an appropriate reference, such as setting up professional groups for training courses, the implementation of construction waste and its environmental impact assessment model, and spread abroad the latest case, research and business opportunities through the network.

The main building and skirt building of this project are excavated respectively, the eastern foundation pit is supported with bond angle of cast-in place pile, the high grouting pile is applied among the pile and is lapped with the supporting pile to form curtain for cutting of water; and the western foundation pit is supported with the underground diaphragm wall and concurrently used as curtain for cutting of water.
The western river to the groundwater level of site (which is mainly quaternary upper pore water has small influence to rangeability.
But in case of flooding the rainy season, the river water can surge over the river, so it has certain influence to construct the west of site, and especially foundation pit of main building.
The groundwater exposed by site is quaternary upper pore and bedrock weathering fissure water, which have slight bearing pressure.
The software Plaxis of professional large geotechnical engineering finite element analysis is use for performing the simulation analysis to the pipe-jacking construction according to the finite element method of plane strain continuous medium.
