Description

Technical Field

[0001] This utility model relates to the field of foundation bearing capacity measurement technology, and in particular to a foundation bearing capacity measurement device. Background Technology

[0002] In the field of foundation engineering, accurately determining the bearing capacity of the foundation is a crucial step in ensuring the safety and stability of structures such as buildings, bridges, and roads. Foundation bearing capacity refers to the ability of foundation soil to resist deformation and failure when subjected to external loads, and its value directly affects the formulation of engineering design and construction plans. Traditional methods for determining foundation bearing capacity mainly include static load tests, standard penetration tests, and dynamic cone penetration tests, but these methods have certain limitations in practical applications.

[0003] Traditional methods struggle to balance accuracy and efficiency. Static load tests offer high accuracy but low efficiency, while dynamic penetration tests are highly efficient but have limited accuracy. Many traditional methods rely on manual operation, which can easily introduce human error and affect the reliability of measurement results. Traditional methods are also less adaptable to site conditions and geological environments, making it difficult to achieve accurate measurements under complex geological conditions.

[0004] Therefore, it is essential to invent a foundation bearing capacity measuring device. Utility Model Content

The foundation bearing capacity testing device includes a stabilizing plate, a penetration rod, a positioning marker, a hammer pad, a sliding rod, a core hammer, a support rod, and a measuring ruler. The positioning marker is fixedly installed on the outer side of the top of the penetration rod, and the hammer pad is fixedly installed on the top of the sliding rod, which in turn is fixedly installed on the top of the hammer pad. The core hammer is slidably installed on the sliding rod, and the support rod is fixedly installed on the surface of the stabilizing plate. The measuring ruler is fixedly installed on the surface of the stabilizing plate and slidably installed inside the positioning marker.

[0006] The hammer includes a force-applying hammer, an extension base, an electromagnet, an electromagnetic generator, and a traction cable. The force-applying hammer is slidably mounted on a sliding rod, and the extension base is fixedly mounted on the outside of the force-applying hammer. The electromagnet is attracted to the surface of the extension base, and the electromagnetic generator is fixedly mounted on top of the electromagnet. The traction cable is fixedly mounted on top of the electromagnetic generator.

[0007] The support rod includes a load-bearing rod, a central seat, an extension rod, a support frame, and guide wheels. The load-bearing rod is fixedly installed on the surface of the stabilizing plate, and the central seat is fixedly installed on the top of the load-bearing rod. The extension rod is fixedly installed above the central seat, and the support frame is fixedly installed on the top of the extension rod. The guide wheels are rotatably installed at both ends of the support frame. A tension cable is wound around the outside of the guide wheels.

[0008] The internal hammer of the through hammer is a standard quality steel hammer body, and a pentagonal channel is set in the center of the hammer, which extends outward; the electromagnet and electromagnetic generator can generate magnetic force and lift the hammer upward by pulling the steel cable.

[0009] The force-bearing rod inside the support rod is an inclined steel metal rod, and the central seat is suspended directly above the hammer through the support of the force-bearing rod. The extension rod and the support frame form a "T"-shaped steel support structure; the guide wheel is a set of two steel metal wheels.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This utility model relates to a through-hole hammer designed to apply standardized impact force. Slidingly mounted on a sliding rod, it falls freely and strikes the hammer pad, transmitting the impact force to the penetration rod, driving it into the foundation. The internal force-applying hammer uses a standard-quality steel hammer body, ensuring consistent impact energy for each strike and improving measurement accuracy and repeatability. Simultaneously, the through-hole hammer is equipped with an electromagnet and an electromagnetic generator, enabling automated operation via a pulling steel cable, reducing human error. Furthermore, the through-hole hammer, in conjunction with the sliding rod, ensures the penetration rod enters vertically, preventing skewing from affecting the measurement results. The overall design enables the through-hole hammer to efficiently and accurately determine the foundation bearing capacity, improving measurement efficiency.

[0012] 2. The support rod of this utility model is fixed to the surface of the stabilizing plate by a force-bearing rod, providing stable support for the entire device and ensuring the stability of the equipment during measurement. The central seat of the support rod is suspended directly above the mandrel, ensuring that the mandrel can move vertically along the sliding rod and avoid tilting. The top support frame is equipped with guide wheels to guide the movement of the traction cable, ensuring that the force-applying hammer can be lifted and released smoothly. The support rod adopts an inclined steel metal rod design, combined with the extension rod and the support frame to form a "T"-shaped steel support structure, further enhancing the stability and anti-tilting ability of the device. The overall design ensures that the insertion rod and the mandrel remain vertical during measurement, thereby improving the accuracy and reliability of the measurement.

[0013] 3. This utility model discloses a foundation bearing capacity measuring device. It assesses the bearing capacity of a foundation using standardized and precise measurement methods, providing reliable foundation mechanical parameters for engineering construction. The device penetrates the foundation using a penetration rod, and, combined with a standardized impact force applied by a center hammer, measures the penetration depth and calculates the bearing capacity. A support rod, through a "T"-shaped steel support structure formed by a load-bearing rod, a central seat, an extension rod, and a support frame, provides stable support for the device. Simultaneously, guide wheels guide the movement of the traction cable, ensuring smooth operation. The device design ensures that the penetration rod and center hammer remain vertical during the measurement process, avoiding skewness, improving measurement accuracy and efficiency. It is applicable to various foundation conditions and provides important data for engineering design and construction. Attached Figure Description
