Description
Technical field
The utility model relates to the deformation joint in the building engineering field, and concrete is the deformation joint of a kind of steam power station steel concrete pipe trench.
Background technology
The cast-in-situ steel reinforced concrete raceway groove of steam power station and other building engineering fields regular meeting under the extraneous factor effect produces distortion, causes cracking even destruction.Deformation joint is the build joint of reserving at this situation, and build joint can be divided into three kinds at shrinkage joint, settlement joint, aseismic joint, but shrinkage joint, settlement joint, aseismic joint often three sew up one in practical engineering application, the unified deformation joint that is called.
Deformation joint uses very general in the pipe of firepower electrical plant, ditch, because the pipe trench of steam power station is mainly used in make up water, recirculated water, draining etc., is water system important in the power plant, so pipe trench just seems very high to the requirement of deformation joint.
The cast-in-situ steel reinforced concrete raceway groove of steam power station is general to be designed according to " steam power station water conservancy project design specifications " (DL/T 5339-2006).The 8.3.16 bar regulation of " steam power station water conservancy project design specifications ": the spacing at cast-in-situ steel reinforced concrete raceway groove shrinkage joint, should be according to local temperature condition, foundation property, channel material, cross dimensions, earthing height, factor such as job practices and construction seasons is determined, is generally adopted 20m ~ 30m.When take measures through the demonstration after, the shrinkage joint spacing can increase.In addition, the 8.3.19 bar of " steam power station water conservancy project design specifications " is further stipulated: cast-in-situ steel reinforced concrete pipe, ditch should arrange flexible interface or settlement joint at two kinds of foundation soil intersections that may produce differential settlement or the two ends by railway, highway, dykes and dams and other fixed buildings.
The shrinkage joint of cast-in-situ steel reinforced concrete pipe, ditch and flexible interface comprise the build joint of reservation and the rubber fastening band that arranges in build joint, rubber fastening band is complied with the direction setting of build joint, and be in the medium position of pipe trench wall thickness, there are some assistants the both sides of rubber fastening band, assistant is cast in the steel concrete of pipe trench of build joint both sides, plays fixedly rubber fastening band.The joint filling board of build joint is filled up in the upper and lower surface setting of rubber fastening band in the build joint, in addition, for preventing that pipe trench from leaking at the build joint place, filleting sealing material is set in the build joint between joint filling board and the upstream face again, close the whole piece build joint, eliminate the influence to pipe trench such as flexible of uneven settlement of foundation and pipe trench with the structure of this shrinkage joint and flexible interface.
At pipe trench bottom foundation soil relatively evenly or under the little situation of pipe trench upper load difference, adopt the above-mentioned deformation joint substantially can engineering demands, but change greatly or under the pipe trench upper load difference situation greatly at pipe trench bottom foundation soil, the rubber fastening band that common plastic deformation seam place arranges is because the effect of shearing, be torn the situation of leaking easily.If deformation joint leaks, not only can cause the waste of valuable water resource, also may cause Power Plant completely not send out owing to the deficiency of the water yield, cause compressor emergency shutdown what is more, produce bigger economic loss and social influence.
The utility model content
It is simple and convenient that the utility model technical issues that need to address provide a kind of construction, can effectively regulate the differential settlement of the flexible and ground of pipe trench, avoid the deformation joint rubber fastening band by drawing crack, a kind of steel concrete pipe trench deformation joint of causing raceway groove to leak.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of steel concrete pipe trench deformation joint, comprise the rubber fastening band that is embedded in concrete reinforced pipe ditch wall thickness middle part along build joint, top and the following joint filling board that all arranges of rubber fastening band in the build joint, arrange between joint filling board above the rubber fastening band and the upstream face and prevent the filleting sealing material that leaks, the joint filling board below the described rubber fastening band is equipped with the shear reinforcement perpendicular to build joint.
Further improvement of the utility model is: the external coating of described shear reinforcement one end has oil layer.
Further improvement of the utility model is: described shear reinforcement line centered by build joint is symmetrical arranged.
Further improvement of the utility model is: the diameter of described shear reinforcement is 20mm, and length is 800mm.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
Steel concrete pipe trench deformation joint of the present utility model is applied to the steel concrete pipe trench of steam power station and other building engineering fields, not only construction is very simple and convenient, and can regulate the differential settlement of the flexible and ground of pipe trench effectively, thereby guaranteed the integrality of pipe trench, avoided deformation joint to be caused the leak generation of situation of pipe trench because of rubber fastening band by drawing crack.
The utility model is provided with shear reinforcement between rubber fastening band and back side; deformation joint since the shearing that the sedimentation of ground causes all born by shear reinforcement; shear reinforcement has good supporting role to rubber fastening band; effectively protected rubber fastening band; avoid the fracture of rubber fastening band and the integrality of pipe trench, and then avoided the leak generation of situation of pipe trench.In addition, shear reinforcement is arranged on away from upstream face, near the position of back side, can slow down infiltration to the corrosion of shear reinforcement, prolongs the application life of shear reinforcement.
The external coating oil layer of shear reinforcement one end makes this section shear reinforcement that the amount of movement of horizontal direction be arranged in concrete, not only satisfied the flexible requirement of steel concrete pipe trench, and the flexible effect of adjusting is remarkable, and functional performance is safe and reliable.
The utility model has only been set up shear reinforcement in original deformation joint, it is comparatively simple and convenient to construct.
