Installing device and method for inclinometer tubes in concrete diaphragm wall

The invention discloses an installing device and method for inclinometer tubes in a concrete diaphragm wall. The device comprises a plurality of the inclinometer tubes, galvanized steel tubes and concrete weight blocks, the bottom of each inclinometer tube is inserted into one galvanized steel tube, the bottoms of the galvanized steel tubes are poured into the concrete weight blocks, steel hangingrings are arranged on the concrete weight blocks, a crane is adopted to hang the concrete weight blocks, the galvanized steel tubes and the poured inclinometer tubes into a slotted hole of the diaphragm wall and slowly lower, the inclinometer tubes on the upper part are connected section by section in the lowering process, and meanwhile clear water is injected into the inclinometer tubes to assist sinking till the concrete weight blocks sink to the bottom of the slotted hole. The device guarantees that the bottoms of the inclinometer tubes are located at relatively stable positions, guarantees the accuracy and reliab
