The content of the invention：
The purpose of this utility model is that and overcomes above-mentioned the deficiencies in the prior art, and provides a kind of pipe gallery
Prefabricated assembled tube coupling, the tube coupling directly can produce side using structure shape in itself and dead load during right angle setting
Waterproof adhesive tape is extruded to the extruding force of extruding force and vertical direction, to reach the purpose of sealing, waterproof.Meanwhile, waterproof adhesive tape
Can at once be installed after the completion of engineering is prefabricated, so as to improve installation effectiveness, reduce field installation procedure, reduce and be constructed into
This.
As above conceive, the technical solution of the utility model is：A kind of prefabricated assembled tube coupling of pipe gallery, its feature exists
In：Including trapezoid tunnel segment structure and inverted trapezoidal tunnel segment structure；The fracture surrounding of the trapezoid tunnel segment structure is formed with tang, convex
Mouth surrounding is formed with waterproof adhesive tape mounting groove, and both sides mounting groove is located at tang front, and upper and lower mounting groove is located at the top surface of tang,
The reserved lifting bolt hole in both sides side wall top of trapezoid tunnel segment structure；The surrounding of the inverted trapezoidal tunnel segment structure is recess；
The tang of the trapezoid tunnel segment structure and the recess of inverted trapezoidal tunnel segment structure realize that " Z " font tongue and groove connects in installation process
Connect.
Above-mentioned trapezoid tunnel segment structure base opening 2.5m~3.0m wide, 1.5~2.0m wide suitable for reading.
Above-mentioned trapezoid tunnel segment structure both sides mounting groove sets rounding bottom land with upper and lower mounting groove connecting part.
Above-mentioned inverted trapezoidal tunnel segment structure 2.5m~3.0m wide suitable for reading, lower mouth 1.5~2.0m wide.
The utility model can save prestress wire or bolt is pre- compared with traditional prefabricated pipe gallery construction technology
The working procedure of tight pressurization, directly can be produced lateral crowded using structure shape in itself and dead load during right angle setting
The extruding force of pressure and vertical direction extrudes waterproof adhesive tape, reaching the purpose of sealing, waterproof.Meanwhile, waterproof adhesive tape can be
Installed at once after the completion of engineering is prefabricated, so as to improve installation effectiveness, reduce field installation procedure, reduce construction cost.

Specific embodiment：
As shown in Figure 1：A kind of prefabricated assembled tube coupling of pipe gallery, by trapezoid tunnel segment structure and inverted trapezoidal tunnel segment structure
Composition.
As shown in Figure 2：Trapezoid tunnel segment structure 1, base opening 2.5m~3.0m wide (standard fragmentation width, according to actual conditions
Can suitably adjust), 1.5~2.0m wide suitable for reading, the surrounding of fracture is formed with tang 31, and waterproof adhesive tape mounting groove 4 is formed with tang 31,
Both sides mounting groove 4 is located at the front of tang 31, and upper and lower mounting groove 4 is located at the top surface of tang 31.As shown in Figure 4：In both sides mounting groove
4 set rounding bottom land 5 with the connecting part of upper and lower mounting groove 4 carries out transition processing.It is pre- at the top of the both sides side wall of trapezoid part
Lifting bolt hole 6 is stayed, lifting installation is carried out using special hanger in later stage installation process.
Fig. 3 be inverted trapezoidal tunnel segment structure 2,2.5m~3.0m wide suitable for reading, (standard fragmentation width can be fitted according to actual conditions
When adjustment), lower mouth 1.5~2.0m wide, front and rear both sides surrounding is recess 32, tongue and groove company is carried out with tang 31 in installation process
Connect.
As shown in Figure 1：The utility model first installs trapezoid tunnel segment structure 1 one by one, after inverted trapezoidal section of jurisdiction knot is installed one by one
