Problems solved by technology
The above-mentioned patents solve the problem to a certain extent that due to the low strength of the silt filling, the construction personnel and machinery need to wait for a long time for its consolidation before entering the construction. The solidification agent, and because the high compressive stress cannot be formed inside the sludge, the curing time is still long;
[0005]On the other hand, crop stalks are one of the main wastes in agricultural production. At present, about 97% of the stalks in the world are burned, piled up and abandoned, which is harmful to the environment. caused great damage

Embodiment Construction
[0030] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0031] Such as Figure 1-Figure 2 As shown, the present invention includes the following characteristic parts: 1 is the main straw rope, 2 and 3 are horizontal straw ropes, 4 is a vertical straw rope, 5 is a positioning rod, 6 is a tightening device, 7 is solidified mud, 8 For the cofferdam.
[0032] A method for forming a straw-solidified sludge ecological hard shell, comprising the following steps:
[0033] Step 1: Evenly insert at least two positioning rods on the cofferdam around the silt storage yard, and every two relative positioning rods separated by the silt storage yard are on the same vertical plane;
[0034] Step 2: Every two relative positionin...

Abstract
The invention relates to a forming method of straw-solidified sludge ecological hard shell and the formed hard shell. The aforementioned hard shell includes at least two horizontal wires arranged in the solidified sludge ecological hard shell and criss-crossing in the horizontal direction. Straw rope, using the reinforcing effect of straw rope, can effectively improve the strength of the hard shell; one end of the vertical straw rope is buried in the mud, and the other end connects two criss-crossing horizontal straw ropes together, using the straw rope Excellent water permeability, forming a drainage system, can reduce the water content of the sludge; through the forming method of the application, not only the amount of curing agent is greatly reduced, but also the thickness of the formed hard shell is greatly reduced, and the strength of the sludge can be improved and the hard shell layer can be increased. The bearing capacity of the shell.
Description
technical field [0001] The invention relates to a forming method of straw-solidified sludge ecological hard shell and the formed hard shell, belonging to the field of foundation treatment. Background technique [0002] The dredging of rivers in our country produces a large amount of dredged silt with high water content every year. Putting the dredged silt into the storage yard for disposal in the storage yard is an important disposal method for the dredged silt at present. In order to save land resources, increase the storage capacity of silt in the storage yard, and at the same time, turn the storage yard into a usable foundation as soon as possible, it is generally necessary to treat the silt in the storage yard. However, since the strength of the dredged silt is almost zero, it is impossible to carry out foundation treatment on the yard silt with large-scale machinery. The commonly used method is to firstly use artificial methods to make a hard shell on the surface of th...
