Embodiment 1

[0030] Embodiment 1 is a coastal soft foundation dam construction project, which is divided into 16 construction unit blocks, and its dam section is as follows: figure 1 As shown, the method includes the following steps:

[0031] A. Lay 500g / m on the embankment that has been measured and set out 2 Needle-punched non-woven geotextiles (2), throw medium-coarse sand with a thickness of 2m and a mud content of less than 5% on the geotextiles as a sand cushion (4), interspersed in a triangular arrangement with a spacing of 1.5m, and a depth of 16m The vertical plastic drainage plate (1) of the vertical plastic drainage board (1), forms the horizontal and vertical drainage channel; B. Buried the instrument, set the sign, lay the filter drainage vacuum pipe; cover three layers of polyvinyl chloride sealing film (5), excavate the vacuum preload Seal the film groove, lay the sealing film and backfill it with silt, and seal the surrounding groove (3); install a vacuum pump, connect the...

Embodiment 2

[0032] Embodiment 2 is the sea reclamation project of a certain soft foundation dam, and its dam section is as follows figure 2 Shown, its method is similar with embodiment 1, and difference is: F. fill the easily subsidence position of embankment core (11) with light material (17), mix in the earthwork of filling with light material (17) (18). G. After the embankment is stable, do the surface laying treatment of the embankment crest (10); use the top concrete (16) on the embankment top, and use concrete (15) on the water face to form slope protection and masonry anti-wave wall, use prefabricated 8 tons Twist " king " word block body face protection, lay face protection block body (14) from bottom to top.

[0033] Through the comparative analysis of various dams, the advantages of the present invention have been fully reflected: the added dam components are connected to each other to form a dam skeleton, which improves the slope coefficient of the dam body, and reduces the f...

Abstract

The invention provides an industrially-manufactured dam component and a method for quickly building dams, and belongs to the technology of dam building. The method comprises the steps that a foundation is quickly processed by the means of a plastic water drainage plate, geofabric, a sand cushion laye, a vacuum pumping combined pre-pressing means and the like; the mode that vacuum pumping is conducted under a sealing film is used, a secondary sand cushion layer is poured on a covered thin film, and an earthwork is input on a prefabricated part; combined prepressing of the water level, sand cushion layer earthwork heaping and vacuum pumping is formed; the method that a prefabricated dam component is built on a processed embankment foundation, the prefabricated dam component and the processed embankment foundation are connected with each other to form a dam framework, and a light cushion layer is laid is used. The stress balance of the dam is adjusted, and differential settlement and landslide are avoided. The problems of foundation strength and earthwork heaping are fundamentally solved, and mechanical and mass construction is facilitated. The advantages of saving cost due to the fact that stones are replaced by earth, increasing the construction speed, being stable and reliable and the like are achieved.

Description

technical field [0001] The invention relates to embankment construction, especially a method for rapid embankment construction on weak foundations. Belongs to dam construction technology. Background technique [0002] Dikes and dams are the general term for dikes and dams, and also generally refer to buildings and structures that are waterproof and water-retaining. There are long coastlines on the earth, and coastal tidal flats are extremely rich in resources, which must resist the erosion of tides and waves. The dam is its extremely important engineering facility. Building dams on natural soft soil foundations is bound to be limited by the physical and mechanical properties of natural foundation soils. Due to the high water content of coastal soils, low foundation bearing capacity, low permeability coefficient, slow consolidation, and high sensitivity, the loading speed must be controlled. The bearing capacity of the foundation is slowly increased before the load can be a...
