Description
Technical field
The present invention relates to one kind to be used for underground utilities ceiling mount bracket and pipeline protection method, and in particular to a kind of interim pipeline
Lower section ceiling mount bracket and excavation fluted tube line guard method.
Background technology
At present, municipal works (including water-supply line, communication pipeline, rainwater pipeline, sewer line, power pipeline) foundation ditch is opened
Change to above foundation ditch (i.e. above earth's surface), it is necessary to will move existing burning line and water supply line temporarily before excavation construction, so
It is the normal use for not influenceing combustion gas and supplying water to do purpose.When burning line and water supply line are moved back, progress groove of moving back is opened
Just interim the burning line changed is moved existing, below water supply line in the region of digging.Due to it is pressed for time, narrow field, it is impossible to
Secondary move is carried out to burning line and water supply line to change, and when digging foundation ditch, very strict is required to burning line and water supply line, combustion
Gas pipeline and water supply line must not move, and must not settle substantially, be needed with reference to the safety guarantee of field condition and burning line, be needed
There is supporting ceiling mount bracket to protect burning line and water supply line, make its immovable and settle.
The content of the invention
The present invention can not carry out secondary moving the feelings changed to solve live excavation to burning line and water supply line
Under condition, it is ensured that burning line and water supply line must not move, and must not settle the problem of obvious, and provide below a kind of interim pipeline
Excavate fluted tube line guard method.
Below a kind of interim pipeline of the present invention ceiling mount bracket include cross bar, vertical rod, suspension rod, diagonal brace, bracket, connecting plate and
Cross bar nut, vertical rod and suspension rod are vertically set on the both ends of cross bar, and vertical rod is located at the lower end of cross bar and welded with cross bar, suspension rod
Upper end is connected through cross bar and connecting plate with cross bar nut thread, and lower end and the bracket of suspension rod are detachably connected, and diagonal brace is arranged on
Between cross bar and vertical rod, one end of diagonal brace is connected with cross bar, and the other end of diagonal brace is connected with vertical rod.
Fluted tube line guard method is excavated below a kind of interim pipeline of the present invention, methods described is through the following steps that reality
Existing：
Step 1: two ceiling mount brackets are arranged in the both ends of longitudinal direction at the top of foundation ditch Guan Liang, on each ceiling mount bracket
Vertical rod is 4m~6m apart from the threshold value of foundation ditch Guan Liang；
Step 2: Guan Liang top steel plate is arranged between vertical rod and foundation ditch Guan Liang, Guan Liang top steel plate is consolidated using expansion bolt
It is scheduled in foundation ditch Guan Liang；
Step 3: vertical rod is connected with cross bar full weld；
Step 4: digging groove below water supply line, lower plate is put in a groove, burning line and water supply line are respectively positioned on
In the framework of bracket, lower plate and two round steel are assembled, tighten suspension bracket nut, bracket is connected with suspension rod；
Step 5: after foundation ditch is dug, when near pipe network channel excavation to bracket of moving back, groove construction side need to again by
Suspension bracket nut on bracket adds stubborn half-turn.
Technical scheme has the advantages that：
First, ceiling mount bracket can be effectively protected to pipeline below interim pipeline of the invention, it is ensured that be excavated
When, pipeline does not move, indeformable.The method of the present invention effectively solves the problems, such as pipeline robust, to ensure that pipeline is moved back work
It is smoothed out providing effective guarantee.
2nd, cross construction can be carried out using ceiling mount bracket below the interim pipeline of the present invention, i.e., after lifting terminates, so that it may
To carry out the work such as channel excavation, not schedule delays.
3rd, the inventive method construction is simple, conveniently, ceiling mount bracket can be carried out in advance prefabricated.
