Abstract
The utility model relates to a dam with silt filled geotextile bags, and relates to dams. The dam is composed of silt, the geotextile bags, plastic drainage plates and precipitation wells. The dam is characterized in that the content of particles of which the particle size is greater than 0.075mm in the silt does not exceed 50% of the total mass; side faces of the geotextile bags are made of composite geotextiles, and upper and lower surfaces of the geotextile bags are made of woven fabrics; prisms formed by the silt filled geotextile bags are arranged on the two sides of the dam, silt fills the middle of the dam to form a core of the dam, and horizontal drainage channels formed by the horizontal plastic drainage plates are formed among the silt filled geotextile bags; the precipitation wells are distributed in the core of the dam. The dam is suitable for causeway, cofferdam, revetment, approach bank, breakwater, sea wall and embankment construction.
Description
Technical field
The utility model relates to the dykes and dams of harbour, water conservancy, highway.
Background technology
At harbour, water conservancy, ground, municipal administration, highway professional domain, complete at present with ongoing geotextile filling bag embankment and formed in dam construction, current specifications requires casting resin should select sandy soil, the granule content that particle diameter is greater than 0.075mm should be greater than 50%, this is easier to realize for the abundant area ratio in sand source, has good using value.But lack for sandy soil, and the resourceful area of silt, because silt particle is thinner, drainage and soil conservation are poor, and dykes and dams soil solidifying is slow, the domestic successful case that rarely has at present the fill of employing silt filling geotextile bag.
Summary of the invention
The problem that the utility model need to solve is lack and under the resourceful condition of silt, research and develop a kind of silt and substitute the dykes and dams that sandy soil filling geotextile bag is constructed at sandy soil.
Silt, geotextile bag, plastic draining board and dewatering well for the technical solution of the utility model Bian, is characterized in that the granule content that particle diameter in silt is greater than 0.075mm is no more than 50% of gross mass; Geotextile bag side adopts composite earthwork cloth, and top and bottom adopt woven cloth to make, and composite earthwork cloth is by 150 ~ 250g/m
2woven fabric and 100 ~ 250g/m
2non-woven geotextile is composited, and woven cloth specification is 150 ~ 300g/m
2; Dykes and dams two sides are the rib body that geotextile bag filling silt builds up, and in the middle of dykes and dams, are the hydraulic reclamation silt dike heart, between the geotextile bag of filling silt, bury level underground to plastic draining board, connect the hydraulic reclamation silt dike heart and the external side of rib, form transverse drainage passage; Dike is distributed with dewatering well in the heart.
Remarkable technological progress of the present utility model is the restriction that has broken through geotextile filling bag in current specifications and need adopt casting resin sandy soil, by taking effective configuration to solve the technical barriers such as drainage, soil conservation, consolidated compacting that silt fill exists be slow, realize direct employing silt filling geotextile bag fill and formed dykes and dams; The main grain group of composition silt is powder, particle size range is between 0.075 ~ 0.005mm, and the physico-mechanical properties of silt is subject to powder control, and particle is thin, hole is little, viscosity is low, weak～medium water permeability, natural drainage consolidation time is long, is difficult to meet dam construction application demand; Once but silt discharging consolidation is closely knit, there is the feature that intensity is high, compactness is high, bearing capacity is high, it is good banking material; The utility model, by adopting the technical measures such as drainage path, dewatering well, foreshortened to the silt discharging consolidation time about 5 days by 20 days above, and bearing capacity of foundation soil meets dam construction application demand.Geotextile bag side adopts composite earthwork cloth, woven fabric intensity is high, porosity is high, non-woven geotextile has the advantages that soil conservation is good, the two is compound, efficiently solve silt and charge draining, the soil conservation technical barrier that geotextile bag exists, and upper and lower sides adopts woven cloth to be beneficial to draining, reduce cost simultaneously; Plastic draining board is set, utilizes plastic draining board to form drainage channel, shorten drainage path; Dewatering well is set, removes the part Free water in silt, dewatering, realizes good closely knit effect.

Detailed description of the invention
The utility model is silt, geotextile bag, plastic draining board and dewatering well (see figure 1) for Bian, and the granule content that in silt, particle diameter is greater than 0.075mm is no more than 50% of gross mass; Geotextile bag (see figure 4) side adopts composite earthwork cloth 8, and top and bottom adopt woven cloth 9, and composite earthwork cloth is by 150 ~ 250g/m
2woven fabric and 100 ~ 250g/m
2non-woven geotextile is composited, and woven cloth specification is 150 ~ 300g/m
2; Dykes and dams two sides are the rib body 1 that geotextile bag filling silt builds up, in the middle of dykes and dams, it is the hydraulic reclamation silt dike heart 2, the level that is embedded with between the geotextile bag of filling silt is to plastic draining board 3, connect the hydraulic reclamation silt dike heart and the external side of rib, form transverse drainage passage, plastic draining board level interval 1 ~ 5m; Dike is distributed with dewatering well 4 in the heart.The utility model construction adopts the low-lying level dynamic compaction machinery 5 that energy is 800 ~ 1200kJ, can accelerate the discharging consolidation speed of the hydraulic reclamation silt dike heart, improves compactness and the bearing capacity of the dike hydraulic reclamation silt dike heart.After the fill of silt filling geotextile bag completes, construct rigidifying structure 6 and outer slope safeguard structure 7.
