Technical field
The utility model relates to a kind of inclinometer pipe, in particular a kind of based on the inclinometer pipe in deep footing groove enclosing structure concrete.
Background technology
In recent years, the underground engineering construction of China, water conservancy construction and urban traffic infrastructure construction all achieve unprecedented development, along with the raising of social production force level and the extensive use of a large amount of new technology, new construction, new technology, new material and new equipment, the building technology of underground construction is made to have also been obtained unprecedented development.
The peak period that China carries out underground engineering construction construction at present, by resource-constrained between hemisphere, the development trend of following infrastructure is city underground engineering Application and Development, in support system space enclosing structure, for ensureing space enclosing structure construction quality, all will carry out super filling by code requirement, general surpassing fills with 50cm, sometimes because construction control is bad, super length of filling with is higher than specification.Inclinometer pipe pre-buried in measuring for foundation ditch, is easily subject to space enclosing structure top super filling concrete chisel removal and is destroyed during Guan Liang construction.
Urban Underground deep pit digging, first Guan Liang construction is carried out by operation, need to cut the super concrete of filling with of space enclosing structure, cut and super fill with general and adopt artificial and machinery to cut, for ensureing space enclosing structure quality, the general artificial chisel that all adopts removes, but artificial chisel except also easily causing inclinometer pipe to be destroyed, fracture, the phenomenon such as the mouth of pipe blocks.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of based on the inclinometer pipe in deep footing groove enclosing structure concrete, and this inclinometer pipe can prevent from cutting in super filling process and damage.
The utility model is achieved through the following technical solutions:
A kind of based on the inclinometer pipe in deep footing groove enclosing structure concrete, its design feature is, comprise PVC inclinometer pipe and steel sleeve, described PVC inclinometer pipe is vertically embedded in space enclosing structure layer of concrete, described PVC inclinometer pipe lower end flushes with the reinforcing cage bottom in space enclosing structure layer of concrete, upper end extend to be positioned at space enclosing structure layer of concrete top hat beam above, described steel sleeve and PVC inclinometer pipe are coaxially arranged, be embedded in space enclosing structure layer of concrete bottom described steel sleeve, top exceeds reinforcing cage 20cm.
Further, described PVC inclinometer pipe and steel pipe socket are fixed by the reinforcing cage be located in space enclosing structure layer of concrete.
Further, described steel sleeve length is 1150mm-1250mm, and the length that described steel sleeve is positioned at space enclosing structure layer of concrete is 500mm-850mm.
Further, described steel sleeve upper end flushes with PVC inclinometer pipe upper end, and described PVC inclinometer pipe height exceeds hat beam upper surface 80-120mm.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model inclinometer pipe is with PVC inclinometer pipe for agent structure is embedded in deep footing groove enclosing structure concrete and hat beam, and due to PVC inclinometer pipe, the cost of material is low, light weight, therefore can be cost-saving, convenient construction, the utility model is when space enclosing structure is constructed, in advance rigid safeguard measure is taked to inclinometer pipe agent structure, namely steel sleeve and PVC inclinometer pipe is adopted coaxially to arrange, be embedded in space enclosing structure layer of concrete bottom steel sleeve, top exceeds hat beam upper surface, prevent from damaging inclinometer pipe agent structure cutting in super filling process, avoid disintegrating slag cleaning in the inclinometer pipe that needs because inclinometer pipe suffers breakage in installation to carry out, to join two pipes together and even plugging such as to scrap at the work, it also avoid simultaneously and affect later stage monitoring measurement work because inclinometer pipe suffers breakage in installation and the security risk brought to deep pit digging, when steel sleeve top flushes with PVC inclinometer pipe top, when can also prevent hat beam concrete from cutting further, inclinometer pipe is not destroyed.
Accompanying drawing explanation
Fig. 1 is the generalized section of using state of the present utility model.
Fig. 2 is using state cross-sectional view of the present utility model.
Number in the figure: 1 space enclosing structure layer of concrete, 2 reinforcing cages, 3 Guan Liang, 4PVC inclinometer pipes, 5 steel pipe sockets.
Detailed description of the invention
Below comprehensive accompanying drawing is described in detail to the utility model; clear, perfect description is carried out to the technical scheme in the utility model embodiment; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
See Fig. 1 and Fig. 2, a kind of based on the inclinometer pipe in deep footing groove enclosing structure concrete, comprise PVC inclinometer pipe 4 and steel sleeve 5, PVC inclinometer pipe 4 is vertically embedded in space enclosing structure concrete 1, its lower end flushes with the reinforcing cage bottom in space enclosing structure layer of concrete 1 or exceeds 20-30cm, upper end extend to be positioned at space enclosing structure concrete top hat beam 3 above, steel sleeve 5 and PVC inclinometer pipe 4 are coaxially arranged, be embedded in space enclosing structure layer of concrete bottom it, top exceeds hat beam upper surface.The utility model, by the setting of steel sleeve, can prevent from cutting in super filling process, pound disconnected PVC inclinometer pipe.Avoid disintegrating slag cleaning in the inclinometer pipe that needs because inclinometer pipe suffers breakage in installation to carry out, to join two pipes together and even plugging such as to scrap at the work, it also avoid simultaneously and affect later stage monitoring measurement work because inclinometer pipe suffers breakage in installation and the security risk brought to deep pit digging.
Wherein, PVC inclinometer pipe and steel pipe socket are fixed by the reinforcing cage 2 be applied in space enclosing structure layer of concrete and hat beam, and the overhead height of reinforcing cage 2 is apart from the low 5-10cm of hat beam upper level.
