Abstract
The utility model discloses a measuring device for pile bearing force for determining pile bearing capacity, which is composed of a lower top plate, an upper displacement transducer and a lower displacement transducer, wherein, the lower top plate is provided with a hydraulic jack whose outer diameter is smaller than the outer diameter of a test pile; the hydraulic jack is composed of a cylinder body and a piston which is butted with the lower top plate; the cylinder body is provided with an oil inlet pipe; the upper displacement transducer is arranged on the cylinder body, and the lower displacement transducer is arranged on the lower top plate; a support casing is arranged outside the cylinder body; an upper top plate is arranged at the top part of an oil cylinder; the support casing is respectively fixed to the upper top plate and the lower top plate, and one of the fixations is firm. The utility model can reduce the cost of a test for determining pile bearing.
Description
The utility model relates to a kind of pile bearing capacity determinator that is used for the load-bearing capacity of definite stake.
Existing similar device is to make one with stake, and its external diameter is isometrical and cylinder wall is very thick with stake, and therefore, this determinator is bulky, from great, be not easy to transportation, install, and the manufacturing cost costliness.
Goal of the invention of the present utility model is to provide a kind of mensuration pile that can reduce to carry the pile bearing capacity determinator of experimentation cost.
The utility model adopts following technical scheme to realize its goal of the invention:
The utility model is made up of lower roof plate 4, upper transfer sensor 1 and bottom offset sensor 2, on lower roof plate 4, be provided with the hydraulic jack of external diameter less than detective pole, this hydraulic jack is made up of cylinder body 5 and piston 6, piston 6 offsets with lower roof plate 4, on cylinder body 5, be provided with oil inlet pipe 7, top offset sensor 1 is located on the cylinder body 5, and the next transfer sensor 2 is located on the lower roof plate 4.
Compared with prior art, the utlity model has following advantage:
1. can adopt the external diameter determinator little than detective pole owing to the utility model, this has just saved a large amount of steel, thus not only of the present utility model cheap, and can reduce the cost of determining the pile bearing capacity test.Simultaneously, because the miniaturization of device makes the utility model be convenient to transportation, install.In addition, the utility model is more suitable for determining in immersed tube bored pile bearing capacity.
2. since the utility model at the outer setting support housing of hydraulic jack, this just makes the utility model keep further having increased the bearing capacity at hydraulic jack position on its basis with low cost, safe, reliable when having improved the utility model work.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model embodiment.
Fig. 3 is the structural representation of the utility model when using in driven cast-in-place pile:
With reference to the accompanying drawings, embodiment of the present utility model being done one describes in detail:
