Background Art

[0002] In subway shield sections, dark tunnel concrete structures, special-shaped concrete curved buildings and municipal engineering, water drill cutting technology is widely used in the drilling and cutting operations of concrete structures. However, due to the curved surface characteristics of concrete structures, the traditional cutting process has many difficulties in fixing the water drill, such as: it cannot be quickly and stably fixed on the curved concrete pipe segment, the cutting line is not straight and beautiful, and manual secondary processing is required in the later stage. Most of them are fixed directly on the concrete pipe segment with fixing bolts, one hole and one fixation, and multiple fixations are required during the cutting process, which wastes a lot of manpower and material resources, and wastes labor and time.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] Example 1

[0017] like Figure 1-2 As shown, the present invention provides a fixing device for water drill cutting on a curved concrete pipe segment, including a water drill fixing base, which is made of two steel plates, namely a first base 1 and a second base 2. The steel plates are cut and formed according to the required size, and a slideway 4 is cut in the middle. The water drill fixing base can slide along the slideway 4. The slideway 4 is used as a guide for the water drill fixing base and the water drill 14 to ensure that the pipe segment cutting line is straight. The first base 1 and the second base 2 are fixedly installed vertically. A φ2cm round hole is opened at each end of the first base 1 and the second base 2 for matching with a fixing bolt 7, namely an expansion screw, and the first base 1 and the second base 2 are fixed to the curved concrete structure 8 by the fixing bolt 7. The water drill 14 is installed on the water drill fixing seat, and a mounting seat 9 is provided on the water drill fixing seat package. A driving rod 10 is provided on the mounting seat 9. The driving rod 10 cooperates with the water drill housing. The axial direction of the driving rod 10 is arranged parallel to the axial direction of the water drill bit. The water drill 14 is driven to move axially by the driving rod 10 to control the cutting depth of the water drill. The driving rod 10 can be set as a screw driven by a motor or as a hydraulic rod controlled by a hydraulic cylinder.

[0018] Adjustable support structures are respectively arranged on both sides of the middle of the first base 1 and the second base 2, and the adjustable support structure includes a mounting plate 11 fixed on the first base 1 or the second base 2, a threaded rod 12 with threaded matching is arranged on the mounting plate 11, and a hinge seat 13 hinged to the threaded rod 12 is arranged at the inner end of the threaded rod 12, and an adjustable threaded rod 12 is arranged in the middle part of the mounting plate 11. The threaded rod 12 is adjusted to make the hinge seat 13 fit with the concrete structure. The adjustable support structure is used to support the gap between the water drill fixing device and the curved concrete structure 8 and adjust the drilling angle, so as to ensure that the first base 1 or the second base 2 fits tightly with the concrete structure to prevent the base from vibrating and displacing during drilling.

[0019] This fixture needs to be firmly fixed to ensure the stability of the water drill in the later construction. The fixing position of the device is parallel to the design line to ensure that the line is straight and beautiful after cutting.

[0020] Example 2

[0021] like Figure 2-3 As shown, in this embodiment, a fixing device for water drill cutting on a curved concrete pipe segment includes a water drill fixing base, which is made of two steel plates, namely a first base 1, a second base 2 and a hinge bolt 3. The steel plates are cut and formed according to the required size, and a slideway 4 is cut in the middle. The water drill fixing seat can slide along the slideway 4. The slideway 4 is used as a guide for the water drill fixing seat and the water drill 14 to ensure that the pipe segment cutting line is straight, and a straight scale line 5 size is engraved on one side of the slideway 4 to control the water drill hole spacing and measure the cutting length. An angle ruler 6 is set on a section of one of the steel plates. In this embodiment, the angle ruler 6 is engraved on the second base 2. The first base 1 and the second base 2 are installed by the hinge bolt 3. When the hinge bolt 3 is loosened, the first base 1 and the second base 2 can rotate around the hinge bolt 3. When the hinge bolt 3 is tightened, the installation angle of the first base 1 and the second base 2 is fixed. The angle between the two tangents can be adjusted according to needs to achieve accurate line shape. A φ2 cm round hole is opened at each end of the first base 1 and the second base 2 for matching with a fixing bolt 7, i.e., an expansion screw, and the first base 1 and the second base 2 are fixed to the curved concrete structure 8 by the fixing bolt 7. The water drill 14 is installed on the water drill fixing seat, and a mounting seat 9 is provided on the water drill fixing seat package, and a driving rod 10 is provided on the mounting seat 9. The driving rod 10 matches with the water drill housing, and the axial direction of the driving rod 10 is arranged parallel to the axial direction of the water drill bit. The water drill 14 is driven to move axially by the driving rod 10 to control the cutting depth of the water drill. The driving rod 10 can be set as a screw driven by a motor or a hydraulic rod controlled by a hydraulic cylinder.

[0022] Adjustable support structures are respectively arranged on both sides of the middle of the first base 1 and the second base 2, and the adjustable support structure includes a mounting plate 11 fixed on the first base 1 or the second base 2, a threaded rod 12 with threaded matching is arranged on the mounting plate 11, and a hinge seat 13 hinged to the threaded rod 12 is arranged at the inner end of the threaded rod 12, and an adjustable threaded rod 12 is arranged in the middle part of the mounting plate 11. The threaded rod 12 is adjusted to make the hinge seat 13 fit with the concrete structure. The adjustable support structure is used to support the gap between the water drill fixing device and the curved concrete structure 8 and adjust the drilling angle, so as to ensure that the first base 1 or the second base 2 fits tightly with the concrete structure to prevent the base from vibrating and displacing during drilling.

[0023] This fixing device needs to be fixed firmly to ensure the stability of the water drill in the later construction. The fixing position of the device is parallel to the design line to ensure that the line is straight and beautiful after cutting.

[0024] The present invention realizes multi-hole cutting through one-time fixing, reduces the consumption of labor and materials, improves construction efficiency, controls the cutting line type, ensures that the cutting line is straight and beautiful, saves labor, and changes from the original one-hole-one-fixing to the current one-time fixing for multi-hole construction, saving a certain amount of labor costs.
