Problems solved by technology

Therefore, there are the following problems in the design and embankment: (1) Weak foundation: the general treatment method is to avoid the weak foundation or excavate the weak soil layer, but for many projects with deep buried soft foundation, this method is not suitable actual
(2) Excessive weight of the embankment: For soft foundations, the heavier the gravity dam, the better. Under the action, the direction of the principal stress of the substratum changes continuously, leading to foundation damage; on the other hand, the overweight of the dam body will limit the height of the embankment crest in the design process, which will easily cause over-waves and over-wave water to wash the embankment. Afterwards, it was washed into a deep ditch, and the wave wall sank and toppled, forming a flood of sea water to wash away the earth embankment, causing the stone retaining wall to collapse layer by layer until the embankment was flattened.
(3) The dam materials are loose and poor in seepage resistance: the dams made of mud and stones are all loose materials for the Shili Long embankment. If the foundation is slightly changed, there will be gaps, and water will leak out.
Leakage of the embankment is a major hidden

Embodiment 1

[0022] Embodiment 1, the beach oil exploration project of a certain oil field builds a drilling platform (artificial island) and a transportation channel (dam) in the intertidal zone. It takes several years when there is oil, and it is abandoned if there is no oil. It was originally built with stone cubes, but due to the weak foundation and the erosion of the tide, it sank within a few days, sinking and filling, filling and sinking. Not only the quantity is big but the cost is high, and it can't work normally. For this reason, according to foundation and actual conditions, the dam body type adopts the method of the present invention, and size is: dam height 5m, dam crest 5m, 17m at the bottom of the dam. Since the dam crest is required to be open to traffic, the outer shell is reinforced concrete, the dam crest cover plate is 15cm thick, and the other hard shell is 10cm; 3 ; The lightweight cushion is foam, with a bulk density of 0.4kN / m 3 . It is assumed that the dam crest...

Embodiment 2

[0023] Embodiment 2, a sluice reconstruction project.

[0024] Due to the low drainage standard of the originally designed 2×3m gate, it cannot meet the flood control and drainage requirements. In order to enhance the flood discharge capacity, the original two-hole sluice was abolished and a 5×5m five-hole sluice was rebuilt. The upstream of the project is the reservoir area, and the downstream is the sea surface, which is greatly affected by typhoons, rainstorms and tides. There are both floods and sea tides, and the hydrological changes are relatively large, which brings difficulties and risks to the construction and maintenance of the cofferdam. Moreover, according to the traditional cofferdam, the foot of the weir is wide, the amount of earthwork is large, the stability is poor, and the demolition is not complete. By adopting the structural method of the present invention, an arched steel plate hard shell structure with a height of 7m and a width of 17m is set, and 0.5m t...

Abstract

The present invention is rainbow type light dam structure and its construction process, and relates to dam building technology. The dam casing is made with high strength material, supported with ribs in the easy-to-deform parts and filled with other material. In soft foundation, light cushion layer is set in some easy-to-subside part; and in girt foundation, continuous antiseepage plates are inserted. The whole dam is integrated for balanced load, strengthened integral stability and raised strength.

Description

technical field [0001] The invention relates to the construction technology of dikes (cofferdams, roadbeds, retaining walls). It is a new type of bionic structure and method for building embankments on weak foundations. The invention relates to a method for factory production of embankment components and rapid embankment construction. Background technique [0002] "Soldiers come to block, water comes to cover up" This is the theory of truth for thousands of years. This seemingly simple embankment structure is not without research. Since Dayu's flood control, according to available historical data, embankment technology has always been a major research topic that threatens people's peace of life and plagues social and economic development. With the development of environmental science, geological science, computer technology, two-phase flow and non-cow flow technology, people's research on dyke technology has developed by leaps and bounds. There are a large number of repor...
