det365中文: 沉积物调查 & 疏浚

What is Sediment Build Up and Why Do I Need A 沉积物调查?

All lakes and 池塘s have a natural life span and fill up with sediment over time.  Sediment accumulation can be accelerated by shoreline erosion, 径流, or the seasonal buildup of organic material like submerged aquatic plants and leaves from trees. 最终, every lake and 池塘 in Illinois and Wisconsin require the sediment to be removed and needs to be dredged in order to maintain their intended use, whether its recreation or stormwater storage.

What Does A 沉积物调查 in Illinois/Wisconsin Involve?

A sediment 调查 tells us how much sediment buildup there is in your lake or 池塘.  它包括一个水深测量, which is an underwater topographical survey of the bottom of water body. It involves measuring the depth of water and the amount of sediment present before we reach the original, 坚硬的底部.  We collect data points throughout the waterbody using either sonar or sediment probing poles, 或两个, 视情况而定, and GPS track data collection points for future reference.  We use ESRI ArcMap software to create bathymetric, 沉积物厚度, and total depth maps and to calculate sediment volumes in order to make recommendations on how much lake sediment removal is necessary.

疏浚

When a sediment 调查 reveals that your lake or 池塘 has an unhealthy accumulation of sediment, 我们通常建议疏浚.  疏浚 is the partial or complete removal of sediment layers rich in nutrients and organic matter.  Often the goal is to return the lake or 池塘 back to its original depth while reducing nutrients, 如磷, that feed alga and aquatic plants that can grow out of control.  经过几十年的沉淀积累, dredging is often the best option to restore a degraded lake or 池塘 back to its beauty and function.

疏浚过程中发生的事情?

When a sediment 调查 reveals that your lake or 池塘 has an unhealthy accumulation of sediment, 我们通常建议疏浚.  疏浚 can be done either hydraulically or manually.  Access is a big factor in determining the most appropriate dredging method for your site, 幸运的是, our equipment is capable of fitting in even the most congested areas of Illinois and Wisconsin

液压挖掘 uses suction and is especially effective when removing loose muck.  液压挖泥船像吸尘器一样工作, sucking up a mixture of sediment and water and transferring it through a hose into, 最常, 脱水袋.  The 池塘 and lake sediment stays in the bag and clean water returns to the waterbody.  液压挖掘 is limited by the onshore space to keep the dewatering bag(s).  液压挖掘 is especially cost-effective when there is a use for the dredge material on site.  Our Truxor mini-hydraulic dredge is great for dredging 池塘s and small lakes or doing maintenance dredging 在更大的水域.

液压挖掘 uses suction and is especially effective when removing loose muck.  液压挖泥船像吸尘器一样工作, sucking up a mixture of sediment and water and transferring it through a hose into, 最常, 脱水袋.  The sediment stays in the bag and cleans water returns to the waterbody.  在液压疏浚期间, polymers are often used as a coagulating agent to bond suspended particles together and aid in the dewatering process.  When the fine particles bond together it increases their overall mass, 也叫絮团, and they drop out of the water column much quicker.

液压挖掘 is limited by the onshore space to keep the dewatering bag(s).  液压挖掘 is especially cost-effective when there is a use for the dredge material on site.  Our Truxor mini-hydraulic dredge is great for dredging 池塘s and small lakes or performing maintenance dredging, 尤其是码头附近, 在更大的水域.

机械挖泥机 work by mechanically digging sediment from the bottom using an excavator with a bucket. Mechanical dredging can be done either in the dry or “in the wet”.  Dry mechanical dredging involves either partially or completely draining the 池塘 or lake and using a long-reach excavator to scoop material from the bottom and into trucks.  The material is either repurposed on-site or transported to the nearest disposal site.

We also have a specialized amphibious excavator which allows us to work farther away from shore or in difficult conditions where a traditional excavator would sink.  在这种情况下, the material is scooped into a barge or sled and then transferred into trucks and hauled away. Wet mechanical dredging does not involve drawing down the 池塘 or lake and therefore can cause sediment resuspension. Wet mechanical dredging is done from shore or from a floating amphibious excavator.

 

允许

不管我们怎么疏浚, regulatory permits are typically required to perform this work.  det365中文提供所有 允许det365中文 作为疏浚作业的一部分.  It should be noted that permitting should begin at least 3-6 months before a project is expected to begin.
