Concrete structure member connects；The upper end of lower supporting part is connected with lower connecting portion；And under the lower surface length of lower supporting part is more than
The length of supporting part upper surface.
The cross section of the upper supporting part is right-angled trapezium, and right-angled trapezium is gone to the bottom as the upper surface of upper supporting part, directly
The trapezoidal upper bottom in angle is the lower surface of upper supporting part；The cross section of the lower supporting part is under right-angled trapezium, and right-angled trapezium
Bottom is the lower surface of lower supporting part, and the upper bottom of right-angled trapezium is the upper surface of upper supporting part.
The upper surface of upper supporting part is provided with the bolt hole I for connecting outer concrete structural elements, in lower support
The lower surface in portion is provided with the bolt hole II for connecting outer concrete structural elements；The lower end of upper connecting portion is provided with spiral shell
Keyhole III, in the upper end of lower connecting portion bolt hole IV is provided with, and the active section position corresponding with upper connecting portion is provided with bolt
Hole V, the active section position corresponding with lower connecting portion is provided with bolt hole VI, and upper connecting portion and lower connecting portion pass through respectively spiral shell
Bolt is connected with active section.Because steel structure member is only framework so the installation of bolt is very convenient with dismounting.
Linked together by active section between upper standard knot of the present utility model and lower standard knot, and the width of active section
Less than upper standard knot and the width of lower standard knot, there is gap between two adjacent activities sections in use, in dismounting,
The hydraulic means such as jack are placed in the gap between active section and are held out against upper standard knot and lower standard knot, replaces active section
Effect, so active section can be removed, and discharge upper standard knot and lower standard knot due to lotuses such as soil pressure, water pressures
The tube coupling internal force that load is caused, can easily remove standard knot group after the completion of release.The utility model simple structure, with reinforced concrete
Soil collectively constitutes prefabricated component and is constructed, and removes and installs conveniently, improves efficiency of construction, and safe and reliable, may be implemented in road and
Building lower section is safe efficient, environmentally friendly and economically builds large-scale rectangular and class rectangle cross-section underground space engineering.

Specific embodiment
As shown in figures 1 to 6, a kind of component easy to disassemble for underground engineering prefabricated component, including standard knot group and active section
5.The standard knot group includes upper standard knot 3 and lower standard knot 4, is connected by active section 5 between upper standard knot 3 and lower standard knot 4
It is connected together, the width of the active section 5 is less than upper standard knot 3 and the width of lower standard knot 4.
The upper standard knot 3 includes upper supporting part 3-1 and upper connecting portion 3-2.The upper end of upper supporting part 3-1 by bolt with
Outer concrete structural elements connects.The lower end of upper supporting part 3-1 is connected with upper connecting portion 3-2.And the upper end of upper supporting part 3-1
Length of the face length more than upper supporting part 3-1 lower surfaces.The cross section of the upper supporting part 3-1 is right-angled trapezium, and right angle is terraced
Shape is gone to the bottom as the upper surface of upper supporting part 3-1, and the upper bottom of right-angled trapezium is the lower surface of upper supporting part 3-1.
The lower standard knot 4 includes lower supporting part 4-1 and lower connecting portion 4-2；The lower end of lower supporting part 4-1 by bolt with
Outer concrete structural elements connects；The upper end of lower supporting part 4-1 is connected with lower connecting portion 4-2；And the lower end of lower supporting part 4-1
