2. The trenching unit of claim 1 , wherein the insert profiles ( 17 a , 17 b ) are formed symmetrically.
3. The trenching unit of claim 1 , wherein the insert profiles ( 17 a , 17 b ) each comprise multiple plug-in blocks ( 18 ).
4. The trenching unit of claim 3 , wherein the plug-in blocks ( 18 ) are arranged in a cross shape.
5. The trenching unit of claim 4 , wherein the plug-in blocks ( 18 ) each comprise reinforcing ribs ( 19 a , 19 b ) arranged in a cross shape.
6. The trenching unit of claim 1 , wherein the contour of the contact surfaces ( 20 ) is formed wavy.
7. The trenching unit of claim 1 , wherein the contact surface ( 20 ) of the adapter ( 15 ) is formed substantially in the form of a ring ( 23 ), the external diameter of the ring ( 23 ) is larger than the diameter of the column openings ( 14 ).
8. The trenching unit of claim 7 , wherein the plug-in blocks ( 18 ) are connected to the ring ( 23 ).
9. The trenching unit of claim 3 , wherein the plug-in blocks ( 18 ) are connected to one another.
10. The trenching unit of claim 4 , wherein the plug-in blocks ( 18 ) arranged in a cross shape are aligned with main ribs of the upper base plate ( 12 ) in at least two directions extending perpendicularly in relation to one another.
11. The trenching unit of claim 1 , wherein multiple adapters ( 15 ) are connected to one another, wherein the position of the adapters ( 15 ) corresponds to the location of the column openings ( 13 a , 13 b ).
12. An adapter for a trenching unit comprising at least two trenching bodies ( 10 a , 10 b ), each of the at least two trenching bodies ( 10 a , 10 b ) comprise an upper base plate ( 11 ), a lower base plate ( 12 ), and hollow columns ( 13 a , 13 b ), the hollow columns ( 13 a , 13 b ) are arranged perpendicularly between the upper and lower base plates ( 11 , 12 ) and form column openings ( 14 ) in the upper and lower base plates ( 11 , 12 ), wherein the adapter comprises a bearing surface ( 16 ) and two insert profiles ( 17 a , 17 b ), the two insert profiles ( 17 a , 17 b ) are arranged on both sides of the bearing surface ( 16 ) and are connected thereto, wherein the two insert profiles ( 17 a , 17 b ) are insertable in a form-fitting manner into the hollow columns ( 13 a , 13 b ) to connect the trenching bodies ( 10 a , 10 b ) and the bearing surface ( 16 ) protrudes outward beyond the two insert profiles ( 17 a , 17 b ), the two insert profiles ( 17 a , 17 b ) each comprise a contact surface ( 20 ) that abuts an inner side ( 21 ) of the hollow columns, the contact surface ( 20 ) is contoured to the inner side ( 21 ) of the hollow columns.
