Description

Technical Field

[0001] The present invention relates to the technical field of composite foundation detection, and particularly to a walking type composite foundation detection device. Background Art

[0002] In the vast coastal areas of our country and on both sides of inland rivers and lakes, the shallow-layer geology is mostly formed by sedimentation: the soil is soft, with a high water content, and is prone to instability under load; and it is impossible to bypass the vast soft soil foundation in land use (the Pearl River Delta is a typical example); in engineering, composite foundations are mostly selected to effectively improve the bearing capacity, and the cement mixing pile is one of the treatment methods: the cement slurry is sprayed into the foundation soil in a rotating manner to form regular and continuous cylindrical cementitious materials, and the pile body of the cementitious material and the soil around the pile jointly form a composite foundation.

[0003] After the construction of the composite foundation is completed, a load test needs to be carried out. At present, the relatively common method is the surcharge method. The reaction force system with sand and gravel as the surcharge material mainly manually builds a surcharge platform. Although this method has low requirements for the test site, it is time-consuming, laborious, has a long test preparation time, resulting in an overly long overall cycle, and with the increase in labor costs, the test cost increases year by year. Summary of the Invention

[0004] The purpose of the present invention is to provide a walking type composite foundation detection device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A walking type composite foundation detection device includes a moving mechanism. Preferably, a load-bearing component is provided on the moving mechanism, support mechanisms that move horizontally are provided on both sides of the load-bearing component, a surcharge platform is provided on the load-bearing component, and a static load detection mechanism is connected below the load-bearing component.

[0006] Preferably, the moving mechanism includes a chassis, crawlers are provided on both sides of the chassis, and the load-bearing component is fixed on the chassis.

[0026] Please refer to Figures 1-9 , the present invention provides a technical solution:

[0027] A walking type composite foundation detection device includes a moving mechanism 1, a load-bearing component 2 is arranged on the moving mechanism 1, a support mechanism 3 that moves horizontally is arranged on both sides of the load-bearing component 2, a surcharge platform 4 is arranged on the load-bearing component 2, and a static load detection mechanism 5 is connected below the load-bearing component 2.

[0028] In this embodiment, the moving mechanism 1 includes a chassis 11, crawlers 12 are arranged on both sides of the chassis 11, and then the load-bearing component 2 is fixed to the chassis 11, and the entire detection device can be driven to move through this moving mechanism.

[0029] In this embodiment, the load-bearing assembly 2 includes two longitudinal load-bearing beams 21 and a plurality of transverse load-bearing beams 22. The two longitudinal load-bearing beams 21 are fixed to the chassis 11, and a reaction beam 23 is arranged between the two longitudinal load-bearing beams 21. Then, the static load testing mechanism 5 is connected below the reaction beam 23. By applying a vertical pressure through the static load testing mechanism 5, the vertical compressive bearing capacity or the horizontal bearing capacity can be observed.

[0030] A plurality of the transverse load-bearing beams 22 are arranged on the longitudinal load-bearing beams 21. Two first hydraulic cylinders 24 extending to both sides are arranged inside each of the transverse load-bearing beams 22, and a plurality of the first hydraulic cylinders 24 on each side are connected to the support mechanism 3. When the first hydraulic cylinders on both sides extend outwards, the support mechanism can be pushed to extend outwards as well.

[0031] A surcharge platform 4 is arranged on a plurality of the transverse load-bearing beams 22 for placing counterweight blocks.

[0032] In this embodiment, the support mechanism 3 includes an extension platform 31. The side of the extension platform 31 is fixedly connected to the first hydraulic cylinder 24. When the first hydraulic rods on both sides extend outwards, the extension platform can be pushed to move outwards, so as to match composite foundations with different building areas.

[0033] A plurality of second hydraulic cylinders 32 are arranged below the extension platform 31. The bottom of the second hydraulic cylinders 32 is fixed to the second cushion blocks 33. By the extension of the second hydraulic cylinders, the second cushion blocks can be made to fit the ground.

[0034] In addition, slide rails 34 are arranged on the lower table surfaces of the extension platform 31 on both sides of each second hydraulic cylinder 32. A slider 341 is arranged on each of the slide rails 34. A movable rod 35 is rotatably connected below the slider 341, and the end of the movable rod 35 is rotatably connected to the second cushion block 33. When the second hydraulic cylinder pushes the second cushion block to move downwards, the movable rod and the slider at its upper end will be driven to move. As the second cushion block approaches the ground, the movable rod is perpendicular to the second cushion block at this time. In this way, the movable rods on both sides and the second hydraulic cylinders can effectively support the extension platform.

[0035] In this embodiment, the surcharge platform 4 includes a bearing plate 41. The bearing plate 41 is fixed to a plurality of transverse load-bearing beams 22. A plurality of concave-shaped chutes 42 are arranged horizontally on the plate surface of the bearing plate 41. Two convex-shaped extension plates 43 arranged oppositely are arranged in each of the concave-shaped chutes 42. The end of each extension plate 43 is connected to the extension platform 31. When the extension platform extends outwards, the extension plates on both sides move towards both sides together, so that the bearing area of the entire bearing plate is increased, and more counterweight blocks can be surcharged.

[0036] In this embodiment, the static load detection mechanism 5 includes a jack 51. The upper end of the jack 51 is fixedly connected to the reaction beam 23, and a first cushion block 52 is fixedly connected below the jack 51. After the jack is jacked up between the ground and the detection device, since the multiple counterweight blocks stacked on the loading platform will continuously apply downward pressure, a displacement sensor 53 and a pressure sensor 54 are installed on the first cushion block 52 at this time, so as to detect the displacement and the pressure received by the jack 51 in real time, and thus obtain the vertical compressive bearing capacity or the horizontal bearing capacity of the composite foundation.

[0037] Working principle: The moving mechanism moves the device to the composite foundation where a load test needs to be carried out, and then through the extension of the first hydraulic cylinder, the support mechanisms on both sides are extended outwards, so as to stretch and extend the entire loading platform to match the support points of the composite foundation. Then, through the extension of the second hydraulic cylinder, the support mechanisms are fixedly supported on the ground of the composite foundation. At this time, the crane places the counterweight blocks on the loading platform, and then under the vertical pressure of the jack of the static load detection mechanism, the displacement sensor 5 and the pressure sensor detect the displacement and the pressure received by the jack in real time, so as to obtain the vertical compressive bearing capacity or the horizontal bearing capacity of the composite foundation.
