Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cast-in-place pile measurement platform. Background Art

[0002] As the most common construction technology in pile foundation construction, bored piles are used very frequently in the industry. The biggest advantage of this type of pile is that it can be applied to various geological conditions. Whether it is soft soil, silt, sand or rock, bored piles can be used for construction. Compared with prestressed high-strength concrete pipe piles, manually dug piles and other pile types that have more stringent geological conditions, bored piles are easy to construct and less affected by geological factors, and have better manual controllability.

[0003] During the bored pile construction process, it is necessary to carry out pile core positioning, casing installation, hole opening acceptance, drilling rig placement, pile hole drilling, rock assessment, hole depth measurement, steel cage production, final hole acceptance, primary hole cleaning, steel cage lowering, secondary hole cleaning, guide tube installation, and underwater concrete pouring. Among them, the hole opening acceptance, hole depth measurement and final hole acceptance all require project-related operators to stand directly above the casing to carry out related measurement work. Usually, an operating platform is set up directly above the casing.

[0004] However, the existing operating platform is a steel mesh made of criss-crossed steel bars welded together. During use, the steel mesh is easy to deviate or slip, and operators are prone to step on air and fall into the pile hole, posing a huge safety hazard. Moreover, the steel mesh does not have a dedicated measuring point, and it is difficult for operators to accurately find the pile core position during hole opening inspection, resulting in distorted measurement data and affecting construction quality.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0025] Reference Figures 1 to 4 An example of the utility model provides a bored pile measurement platform, including a frame 100, a support plate 110 arranged on the frame 100, a length measuring hole 120 is arranged at the center of the support plate 110, the length measuring hole 120 is used to accommodate the length measuring rope to fall to the bottom of the pile hole, the length measuring hole 120 is covered with a cover plate 130, a pile core positioning point 140 is arranged at the center of the cover plate 130, and the pile core positioning point 140 is a concave point. A plurality of limit blocks 150 are arranged at the bottom of the frame 100, and the limit blocks 150 are used to limit the outer periphery of the casing 250.

[0026] It should be noted that, in order to facilitate placing the platform on the casing 250, there is a certain gap between the limit block 150 and the outer side of the casing 250, and a wooden wedge can be inserted into the gap between the limit block 150 and the casing 250 to prevent the platform from shifting.

[0027] By setting the skeleton 100, the skeleton 100 can provide support force for the support plate 110 and increase the overall structural strength of the platform. A plurality of limit blocks 150 are set at the bottom of the skeleton 100. On the one hand, the outer periphery of the casing 250 can be limited to prevent the platform from shifting, thereby improving the stability and safety of the platform. On the other hand, the skeleton 100 and the support plate 110 can be positioned so that the center of the support plate 110 is located at the center of the casing 250, and the length measuring hole 120 and the cover plate 130 are located at the center of the support plate 110, so that the pile core positioning point 140 on the cover plate 130 is aligned with the center of the casing 250.

[0028] When the operator is inspecting the hole opening, the cover plate 130 is placed on the length measuring hole 120, and the operator places the measuring instrument on the pile core positioning point 140, thereby facilitating the operator to accurately locate the pile core, ensuring that the measuring instrument will not shift, and improving the accuracy of the measurement data.

[0029] When measuring the hole depth, the operator opens the cover plate 130 covering the length measuring hole 120, and drops the measuring rope from the length measuring hole 120 to the bottom of the pile hole, thereby facilitating the operator to measure the hole depth and improving convenience.

[0030] In some preferred embodiments, the skeleton 100 includes a cross beam 160, a longitudinal beam 170 and a circular ring beam 180.

The inner hole of the vertical pipe 200 forms a length measuring hole 120, and the cover plate 130 is covered on the top of the vertical pipe 200. Specifically, the cross-sections of the cross beam 160 and the longitudinal beam 170 are both square, and the vertical pipe 200 is a square tube. The cross beam 160 and the longitudinal beam 170 are respectively fixedly connected to the adjacent two sides of the square tube, thereby facilitating the connection of the cross beam 160 and the longitudinal beam 170.

[0033] Furthermore, one side of the riser 200 is connected to one side of the cover plate 130 via a hinge 210, so that the cover plate 130 can be flipped over for easy operation and to prevent the cover plate 130 from being lost.

[0034] In some preferred embodiments, the support plate 110 is a metal mesh. On the one hand, the metal mesh can prevent water accumulation, and on the other hand, it can increase friction to prevent workers from slipping and improve its safety performance.

[0035] In some preferred embodiments, a fence 220 is provided on the circular ring beam 180, and the fence 220 is provided with an opening section.
