Embodiment

[0028] Example: such as Figure 1-6 As shown, the present embodiment relates to a discontinuous PRB reaction column layout method, the method steps are as follows:

[0029] a. Calculate the spacing, thickness, number of rows and height of the reaction column 1;

[0030] B, select the medium reaction material of reaction column 1;

[0031] c. If Figure 5 As shown, according to the calculated spacing, thickness, row number and height of the reaction column 1, the construction is carried out according to the following process:

[0032] (1) Make a plan according to the calculation results, and obtain the coordinates or latitude and longitude of each reaction cylinder;

[0033] (2) According to the longitude, latitude and coordinates of the reaction cylinder, use theodolite to place and locate points;

[0034] (3) Use a professional engineering drilling rig to drill holes, dig multiple wellheads, and fill the tube wells 3 below each wellhead with filter material and form a wel...

Abstract

The invention discloses an arrangement method of discontinuous PRB reaction columns. The arrangement method comprises the following steps: a, calculating the spacing, thickness, row number and heightof the reaction columns; b, selecting a medium reaction material of the reaction column; c, digging a tube well according to the calculated spacing, thickness, row number and height of the reaction columns, and filling the tube well with the medium reaction material to form the reaction columns; and d, completing the arrangement of all the reaction columns. The method has the advantages that on the premise that the repairing effect is not affected, the construction cost is effectively reduced, and the constructability is improved.

Description

technical field [0001] The invention relates to the technical field of environmental geotechnical engineering, in particular to a method for arranging discontinuous PRB reaction columns. Background technique [0002] Permeable reaction technology (PRB) is an effective in-situ remediation technology for groundwater pollution that has developed rapidly in recent years. PRB technology does not require external force devices, and the reaction rate of the active medium is very slow. It can play a repairing role for a long time, and has little disturbance to the ecological environment. Except for a large one-time investment and long-term monitoring, it requires almost no cost. For the reclamation site The fit is high. [0003] In the field of conventional groundwater remediation, PRB is gradually replacing the pumping treatment technology with high operating costs, and has become the most promising in-situ remediation technology for groundwater pollution. In a broad sense, PRB t...
