Abstract:

There is mounting evidence that the increasing size of the construction industry may lead to significant changes in the global environment. Dewatering, as a crucial component of the construction industry, may have detrimental consequences on the soil and groundwater quality. Dewatering is a technique used to lower the high-water table during construction. The possible effects of dewatering on the soil and ground water quality were visualized and investigated using GIS technology. The analyses were conducted at small temporal and spatial scales. The aim is to give insights in the magnitude and

This paper reports the dewatering scheme of a deep excavation in sandy pebble strata. The excavation is in high permeability strata and is close to the Yellow River, making the dewatering difficult during construction. At present, few researchers have specially studied the dewatering scheme of deep excavations in strong permeable strata near the water resource. Field pumping test was conducted before the excavation activity, and the permeability coefficient of the strata was obtained by reverse analysis.

Dealing with contaminated effluent can be problematic when dewatering is required in the course of removing buried tanks, excavating contaminated soils or constructing groundwater remediation systems. An engineering solution put forward in this paper is the emplacement of a sandpack, around the dewatering well(s), that reacts with and sequesters groundwater contaminants of concern. If an appropriate granular reactive material is available, placing that material around the dewatering well screen can achieve a degree of contaminant treatment in-situ that may considerably reduce the costs of stor

A large amount of groundwater dewatering is beneficial to the foundation pit construction, but it will cause surface collapse, waste groundwater resources and damage the groundwater environment.

Flowing sand is a special surrounding rock encountered by tunnel construction. Due to the looseness and low viscosity of the flowing sand, after excavation, the sand body is easy to flow along the open surface. In addition, the water seepage also causes tunnel instability. Considering the characteristics of water seepage, how to improve the stability of flowing sand bodies and prevent the instability of surrounding rocks has become a difficult problem. In this paper, a parametric experiment on the surrounding rock taken from the project site was carried out, and then, a numerical simulation of

Abstract:

This study investigates the sustainable use of seabed dredged sediments and water treatment sludges as construction materials using combined dewatering and cement stabilization techniques. Dredged sediments and water treatment sludges, typically considered waste, were evaluated for their suitability in construction through a series of dewatering and stabilization processes. Dewatering significantly reduced the initial moisture content, while cement stabilization improved the mechanical properties, including strength and stiffness. The unconfined compressive strength (UCS), shear modulus, and m

Abstract:

Groundwater is unfavorable for construction activities, so groundwater dewatering or freezing needs to be carried out. The Happy complex is located in Tay Ho District, Hanoi city. The complex is to be constructed with 47 stations which are evenly distributed over a construction area of 10,000 m2 in the depth from 12.1 to 18.25 m below the ground surface. It is required to dewater groundwater to have the groundwater level to be 1.5 m lower the bottom of the stations. Vertical groundwater wells have been selected for the. The determination of groundwater pumping rates for the dewatering had been

Abstract:

This study addresses the water basin effect in the underwater sand layer of steel pipe pile cofferdams by integrating the concept from building foundation pits to cofferdam foundation pit analysis. A theoretical derivation is presented for the deformation evolution of steel pipe piles and bottom seals within the cofferdam pit. The cofferdam construction dewatering process is divided into four stages: riverbed excavation for bottom sealing, dewatering to the second support, dewatering to the third support, and dewatering to final bottom sealing. The steel pipe piles are modeled as single-span o

This paper reviews the process used to design the construction dewatering system at the Influent Pumping Station at Annacis Island Wastewater Treatment Plant. The design process followed the "observational method," as applied to soil mechanics by K. Terzaghi and set out by R.B. Peck in the Ninth Rankine Lecture. The design was based on a working hypothesis of behaviour anticipated under the most probable conditions identified in the data gathering and assessment program. The sensitivity of the design was evaluated by considering potentially unfavourable conditions evident in the available data

Abstract In recent years, underground spaces have expanded widely in the urban zone. The appropriate estimation number of dewatering well with economical costs and securing soil stability at construction sites is challenging in designing pumping schemes. This paper aims to present the numerical approach for the optimal number of wells for designing a dewatering deep foundation pit. First, the estimated hydraulic conductivity was selected among the Theis, Cooper-Jacod, and reverse groundwater modeling methods. The estimated hydraulic conductivity via reverse groundwater modeling shows the lowes

Abstract:

Sediment barriers are used on construction sites to protect downstream waterbodies from the impacts of sediment-laden stormwater runoff. Although ubiquitous on construction sites, many sediment barrier practices lack performance-based testing to determine effectiveness and treatment mechanisms, with previous evaluations being limited to conditions local to the Southeastern U.S., with conditions in other regions remaining untested. Testing was conducted to determine the effectiveness of woven silt fence barriers and provide structural improvements to common installation methods. Testing was con
