Description

Foundation bearing capacity detection equipment

Technical Field

The utility model relates to a technical field building technical field specifically is a foundation bearing capacity check out test set.

Background

The bearing capacity of the foundation is the bearing potential exerted along with the increase of the load on the unit area of the foundation soil, and the common unit KPa is a comprehensive word for evaluating the stability of the foundation. It should be noted that the bearing capacity of the foundation is a practical term for foundation design to facilitate evaluation of the strength and stability of the foundation, and is not a basic property index of soil. The shear strength theory of soil is the theoretical basis for researching and determining the bearing capacity of the foundation.

In the general foundation bearing capacity detection process, a probe rod is usually driven into a foundation, the number of hammering times required for driving the probe rod into a certain depth is recorded to embody the bearing capacity of the foundation, the current detection method is to sleeve a heavy hammer on the probe rod and manually lift the heavy hammer, then loosen the heavy hammer and drive a probe into the foundation, and the method needs a person to hold the probe rod and lift the heavy hammer, so that the danger is easily caused by errors; meanwhile, the lifting distance is difficult to grasp when the heavy hammer is lifted manually, so that the hammering force is different every time when the hammer is dropped, and the detection result is inaccurate.

The utility model provides a foundation bearing capacity check out test set, including base, roof and the support of connection between base and roof, the top surface center of base is equipped with the through-hole, the vertical probe of having placed in the through-hole, the bottom of probe is leveled with the bottom surface of base, the top fixedly connected with hammer stem of probe, the bottom of hammer stem has the boss, the cover is equipped with sliding fit's weight with it on the hammer stem, the both sides of weight have the horizontal pole, the cover is equipped with running fit's movable pulley with it on the horizontal pole, biax synchronous machine is installed to the top surface of roof, respectively the cover is equipped with fixed connection's take-up pulley with it in two pivots of biax synchronous machine, the take-up pulley hanging wall is around there being the steel cable, the top surface of roof is located the take-up pulley below and still is equipped with the square hole, walk.

Furthermore, a linear bearing is sleeved in the through hole and is tightly matched with the through hole, and the probe rod is placed in the linear bearing and is in sliding fit with the linear bearing.

Furthermore, the top end of the probe rod is in threaded connection with a boss at the bottom end of the hammer rod.

Furthermore, scales are arranged on the side surface of the probe rod.

Furthermore, the top of hammer stem is equipped with the gag lever post, and the bottom of gag lever post is equipped with distance sensor, and distance sensor and biax linear electric motor signal connection.

Compared with the prior art, the utility model discloses the beneficial effect who gains does: the utility model has novel structure, adopts the double-shaft synchronous motor to replace the manual lifting of the heavy hammer, and improves the safety of building construction; meanwhile, the lifting height can be better controlled by adopting a double-shaft synchronous motor, and the accuracy of a detection result is improved.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
