Abstract
Description
Technical Field
[0001] This utility model relates to the field of static load testing technology for foundation piles, and in particular to an auxiliary accessory for testing the horizontal bearing capacity of foundation piles. Background Technology
[0002] Since ground-based foundation piles are mostly constructed on hillsides, deserts, wastelands, fields, tidal flats, and swamps, they serve as a crucial structure for photovoltaic power stations, bearing the weight of the support structure and photovoltaic modules, and resisting all dynamic loads, including wind loads, snow loads, rain loads, and seismic loads. Under dynamic loads, if the foundation piles are unstable, the support structure may experience uplift, displacement, uneven settlement, or breakage, severely impacting the normal operation and lifespan of the photovoltaic power station. Therefore, in the construction of photovoltaic power stations, it is extremely important to emphasize the control and testing of the bearing capacity of the foundation piles, both in the design and construction phases.
[0003] Currently, static load testing of foundation piles faces several challenges. Firstly, ground-mounted photovoltaic power stations are often built in the field, and heavy static load testing equipment increases the difficulty of the test. Secondly, the use of cranes for hoisting, erection, and dismantling is cumbersome and time-consuming, hindering cost savings. Thirdly, when testing the horizontal bearing capacity of the foundation, the existing method involves fixing the measurement on top of the foundation. This is inconvenient, requires building high scaffolds to support the jacks, is inefficient and unsafe, and necessitates operators climbing onto the foundation piles to fix the device, which is time-consuming, labor-intensive, and poses safety risks.

It is not only simple in structure and easy to operate, but also can significantly reduce the testing period and testing cost.
[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides an auxiliary accessory for detecting the horizontal bearing capacity of a foundation pile, including a force-measuring horizontal bar. The length of the force-measuring horizontal bar is adjustable. Both ends of the force-measuring horizontal bar are respectively connected to an arc-shaped plate and a flat plate. The arc-shaped plate is used to support the side wall of the foundation pile, and the flat plate abuts against a jack. The force-measuring horizontal bar is placed horizontally.
[0006] In one embodiment, the force-measuring crossbar includes a first sleeve and a second sleeve. One end of the first sleeve is fixedly connected to the arc-shaped plate, one end of the second sleeve is fixedly connected to the flat plate, and the other end of the second sleeve is movably connected to the other end of the first sleeve.

The two force-measuring crossbars are symmetrically arranged, and the arc-shaped plates of the two force-measuring crossbars abut against the sidewalls of the piles respectively.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] The purpose of this invention is to provide an auxiliary accessory for testing the horizontal bearing capacity of foundation piles, so as to solve the problems existing in the prior art. It is not only simple in structure and easy to operate, but also can significantly reduce the testing period and testing cost.
[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1-3 As shown, this utility model provides an auxiliary accessory for testing the horizontal bearing capacity of a foundation pile, including a force measuring crossbar. The length of the force measuring crossbar is adjustable. The two ends of the force measuring crossbar are respectively connected to an arc plate 5 and a flat plate 1. The arc plate 5 is used to support the side wall of the foundation pile, and the flat plate 1 abuts against the jack 6. The force measuring crossbar is placed horizontally.
[0024] The arc-shaped plate 5 is pressed against the side wall of the foundation pile, and a horizontal force measuring bar is placed horizontally. The other end of the force measuring bar is jacked by jack 6 to apply horizontal bearing force, thereby applying a horizontal load to the test foundation pile.
[0025] In one embodiment, the force measuring crossbar includes a first sleeve 4 and a second sleeve 2. One end of the first sleeve 4 is fixedly connected to the arc plate 5, one end of the second sleeve 2 is fixedly connected to the flat plate 1, and the other end of the second sleeve 2 is movably connected to the other end of the first sleeve 4. The length of the force measuring crossbar can be changed by changing the relative position of the first sleeve 4 and the second sleeve 2 to adapt to different pile spacings.
[0026] In one embodiment, one end of sleeve 4 is welded to the arc-shaped plate 5, and one end of sleeve 2 is welded to the flat plate 1. The arc-shaped plate 5 abuts against the outer surface of the pile, and the arc-shaped surface of the arc-shaped plate 5 is fitted to the arc-shaped surface of the pile, which can better transfer the horizontal bearing capacity to the surface of the pile.
[0027] In one embodiment, a plurality of pin holes 3 are evenly distributed along the length of sleeve 4; a plurality of pin holes 3 are evenly distributed along the length of sleeve 2. The length of the force-measuring crossbar is adjusted by changing the corresponding positions of the pin holes 3 on sleeve 4 and sleeve 2. After determining the length of the force-measuring crossbar, pins are inserted into the corresponding pin holes 3 on sleeve 4 and sleeve 2.
[0028] In one embodiment, sleeve 2 is fitted inside sleeve 4; based on the distance between the foundation pile and the jack 6, the corresponding pin hole 3 on sleeve 4 and the corresponding pin hole 3 on sleeve 2 are connected by a pin shaft.
[0029] In one embodiment, such as Figure 3 As shown, during use, two force-measuring crossbars are installed between two adjacent piles. The two force-measuring crossbars are symmetrically arranged, and the arc-shaped plates 5 of the two force-measuring crossbars abut against the side walls of the piles. A jack 6 is installed between the flat plates 1 of the two force-measuring crossbars. The flat plate 1 has mounting holes, and the jack 6 is fixed to the flat plate 1 by bolts passing through the mounting holes.
[0030] The auxiliary accessory for testing the horizontal bearing capacity of foundation piles in this utility model can measure the horizontal bearing capacity between two foundation piles. The force-measuring crossbar consists of two sleeves, with a pin hole 3 at the sleeve joint. The pin can adjust the joint length of the two sleeves, thereby adjusting the overall length of the force-measuring crossbar. Simultaneously, one sleeve 4 is welded with an arc-shaped plate to better support the foundation pile, and the other end supports one end of a jack 6. The other end of the jack 6 is also equipped with a set of force-measuring crossbars to support another foundation pile. The entire auxiliary accessory for testing the horizontal bearing capacity of foundation piles can be placed on scaffolding without requiring manual climbing, reducing transportation difficulty and costs. The ease of assembly and disassembly makes the testing operation more convenient, reducing construction safety risks, shortening the testing period, and lowering testing costs.
