摘要： A method for reinforcing soft ground by post-grouting combined with pressurized vacuum preloading is proposed, by pre-burying prefabricated vertical drains and air-boosted pipes in granular material piles, and the air-boosted pipes are used as grouting pipes to reduce the number of times of piling, which not only improves the construction efficiency, but also reduces the structural disturbance of the soil and the influence of smear effect, thus reducing the impact on the radial permeability and the radial consolidation coefficients. The method does not use geotextile bags for granular materials, which can avoid the problem of forming a localized clogging area around the geotextile bags, and the method not only improves the efficiency of vacuum transfer in a pre-consolidation stage, but also improves the grouting effect in the later stage, effectively enhances the strength of soft soil and makes granular material piles and the surrounding soil form composite ground.

摘要： A core sheet includes a primary textured surface and separate secondary cuspations or corrugations. The core sheets are configured for use within a fluid or wastewater treatment unit that typically includes one or more fabric layers. The primary textured surface enhances retention of wastewater fluid received by the unit, which over time causes an increase in build-up of biomatter on the surface, which in turn enhances the efficacy of treatment of the wastewater.

摘要： A French drain drainpipe with built-in means for flushing iron ocher out of the drainpipe, out of the perforations, and out of the gravel surrounding the drainpipe. Said means may include chambers for receiving pressurized washing fluids and exit orifices from the chambers. Fittings are provided for connecting the chambers to a pressurized source of washing fluids, such as hose fittings for connecting to a normal household water supply.

摘要： A trenchless collector system is configured to intercept and direct surface and/or subsurface fluids to a designated reception location to control groundwater elevations. A target collection and drainage area is identified and a gravity drainage pipe is accessed or trenchlessly installed at the target collection and drainage area. The gravity drainage pipe can be accessed at one or more drawdown points. One end of a collection pipe can be connected to the gravity drainage pipe. Surface and subsurface water is hydrostatically drawn into the collection pipe from the target collection and drainage area through venting at the one end of the collection pipe connected to the gravity drainage pipe. The surface and subsurface water can be passively drained from the collection pipe into the gravity drainage pipe and onto the designated reception location.

摘要： A substantially polygonal drainage channel system is provided. The drainage channel can include a substantially polygonal cross-section that can have rounded corners or edges. More specifically, the cross-section of the drainage channel can be formed to resemble an “upside-down pear.” The drainage channel can have a cross-sectional shape that can be created by first placing two circles of different diameters on top of one another. The “top” circle can be larger than the “bottom” circle. The two circles can then be connected with two tangential lines, one on each side, resulting in a shape in which a top of the drainage channel tapers down toward a bottom of the drainage channel. The drainage channel can also include ribs, drainage slots, and a connector-check valve. A method for installing a drainage channel is also provided.

摘要： The present disclosure provides a system for accelerating salt leaching and drainage of soil based on a negative pressure, and relates to the technical field of soil improvement. The system includes a concealed pipe. The concealed pipe is communicated with a negative pressure chamber. The negative pressure chamber is communicated with an air extracting pump through an air extraction port, and the air extracting pump is configured to evacuate the negative pressure chamber. In the present disclosure, the concealed pipe is arranged, the structure of the concealed pipe is improved, and the negative pressure chamber is arranged between the air extracting pump and the concealed pipe. By evacuating the negative pressure chamber to form a negative pressure area around the concealed pipe for field drainage, the drainage of water in soil is accelerated by the pressure difference, thereby improving the efficiency of drainage and salt leaching per unit time.

摘要： A warning device for detecting water level in drainage well includes at least one level sensor and a transceiver. The level sensor includes an antenna and a first processing unit connected to the antenna. The first processing unit controls the antenna to transmit a signal to the transceiver as to increased fluid levels. The transceiver includes a first communication module and a second processing unit, the first communication module receives the signal and the second processing unit obtains the signal from the first communication module and determines the location of the level sensor and its urgency according to whether the signal decays or disappears because of inundation by drainage fluid. The second processing unit further sends information of the target level sensor to a terminal device.

摘要： A plastic arch-shape cross section corrugated stormwater chamber has a multiplicity of crest corrugations and valley corrugations which run transverse to its length. Sub-corrugations run along part or all of the arch-curve lengths of either crest corrugations or valley corrugations, or along both of them. A sub-corrugations are smaller in dimension than an associated crest corrugation or valley corrugation. Sub-corrugations may taper in width and depth and may taper to nothingness. A compound convex shape end cap, useful for closing off the ends of stormwater chambers, has substantially vertical corrugations with analogous sub-corruptions.

摘要： A modular porous swale. The modular porous swale may comprise a porous concrete block and filtration joint. The porous concrete block may snugly fit within a trench having a lower portion filled with an absorption media. The absorption media may include gravel, activated alumina, bone char, or an activated alumina and bone char mixture. The porous concrete block may have a top surface inwardly-sloped to a nadir. The filtration joint may be disposed within the porous concrete block and along the nadir. The liner may cover one or more sides of the porous concrete block. The perforated pipe may be located within the absorption media. The filtration joint may substantially align above a portion of the perforated pipe when the modular porous swale is installed within the trench.
