Description

Technical Field

[0001] This utility model relates to the field of piling construction technology, and in particular to a piling platform for waterfront construction using steel pipes. Background Technology

[0002] When constructing in a water-adjacent environment, the pile foundation is designed on the water-adjacent bank of the river. Common river piling construction methods include: Larssen steel sheet pile cofferdam, earth filling cofferdam, steel pipe pile cofferdam, caisson construction, etc.

[0003] A search revealed Chinese patent CN109281328B, which discloses a precise construction method for positioning piles of steel cofferdams, relating to the field of bridge construction technology. The method includes the following steps: A) Constructing a construction platform on a steel trestle bridge platform; B) Measuring the position of the steel casing; using a pile driver on the construction platform to drive the steel casing into the riverbed; forming a positioning pile construction area inside the steel casing; C) Measuring the position of the positioning piles within the positioning pile construction area; using a pile driver on the construction platform to drive the positioning piles from the construction area into the riverbed; D) Removing the positioning steel casing. The steel casing acts as a water barrier, ensuring that the water within the positioning pile construction area is still and free from flow, thus preventing the positioning piles from being affected by water flow during driving, resulting in precise positioning pile construction and consequently, precise lowering of the steel cofferdam.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] The aforementioned patented construction materials are expensive, require multiple steel casings, and involve additional pile driving and extraction operations, which have a greater impact on the surrounding environment and sensitive structures. The construction costs and time are significantly increased, thus limiting its effectiveness. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a water-side piling platform constructed with steel pipes, which is low in cost, quick to erect and dismantle, has a short construction period, and does not damage the river environment.

[0007] The technical solution to achieve the purpose of this utility model is: a water-side piling platform constructed with steel pipes, including patterned steel plates and supporting components;

[0008] A steel casing is installed through a patterned steel plate, and a shock-absorbing rubber plate is fixedly installed between the steel casing and the patterned steel plate.

[0009] Preferably, the support assembly includes multiple uprights fixedly installed on the bottom of the patterned steel plate, and the uprights are arranged around the steel casing.

[0010] Preferably, a platform guardrail is fixedly installed on the surface of the patterned steel plate, horizontal bars are fixedly installed between the multiple uprights, and vertical bars are fixedly installed between the multiple horizontal bars.

[0011] Preferably, a pair of horizontal scissor braces are fixedly installed on the crossbar, and a pair of vertical scissor braces are fixedly installed on both sides of the upright.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model is used when the pile foundation design is located near the riverbank, avoiding the use of relatively complex construction methods such as Larssen steel sheet pile cofferdams, earth-fill cofferdams, steel pipe pile cofferdams, and caisson construction.

[0014] Secondly, this utility model is easy to construct and has low construction costs. It allows workers to quickly set up or dismantle the structure, can be recycled to reduce material costs, has a short cycle time, does not damage the river environment, protects the natural ecology, and is a green construction method.

[0015] This solution addresses the problems of high cost of existing patented construction materials, the need for multiple steel casings, and the additional piling and extraction operations that cause greater impact on the surrounding environment and sensitive structures, significantly increasing both construction costs and time.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved version of a water-based piling platform constructed with steel pipes. The technical solution of this utility model is as follows:

[0025] like Figures 1-4 As shown, a water-based piling platform constructed with steel pipes includes a patterned steel plate 1, a support platform that provides a foundation for personnel construction, and also includes support components and a steel casing 3.

[0026] The steel casing 3 is installed through the patterned steel plate 1. A shock-absorbing rubber plate is fixed between the steel casing 3 and the patterned steel plate 1. The casing is fixed around the perimeter with steel clamps. The steel casing 3 is fixed by the cooperation of the rubber plate and the clamps to ensure its stability in working condition.

[0027] The support assembly includes multiple uprights 5 fixedly installed at the bottom of the patterned steel plate 1. The uprights 5 are arranged around the steel casing 3 to provide strong support for the platform and prevent dangerous situations such as collapse.

[0028] Platform railings 2 are fixedly installed on the surface of the patterned steel plate 1. Horizontal bars 4 are fixedly installed between multiple uprights 5, and longitudinal bars 7 are fixedly installed between multiple horizontal bars 4, further reinforcing the connection between steel pipes and avoiding more complex construction methods such as Larssen steel sheet pile cofferdams, earth-fill cofferdams, steel pipe pile cofferdams, and caisson construction.

[0029] A pair of horizontal scissor braces 6 are fixedly installed on the crossbar 4, and a pair of vertical scissor braces 8 are fixedly installed on both sides of the upright 5, enabling rapid construction, convenient disassembly, and reusability.

[0030] The specific working method is as follows: First, load calculation and structural design are carried out. Based on the self-weight of the reverse circulation drilling rig, the dead load of the drilling tools (steel casing 3, drill rod, etc.), the construction live load (personnel, material stacking, dynamic coefficient), and wind load, the total load of the support (including a safety factor ≥ 1.5) is calculated; the spacing of the uprights is determined by back-calculation of the bearing capacity to ensure that the axial force of a single upright 5 is ≤ the allowable bearing capacity of the steel pipe; the horizontal bar spacing is set according to the stability requirements to ensure that the slenderness ratio λ ≤ 150; then the structural measures are set, and vertical scissor bracing 8 is continuously set along the outer facade of the support; at the top layer, A layer of horizontal scissor bracing 6 is installed every ≤6m at the bottom and middle levels; outriggers (anti-overturning): when the support height is ≥6m, outriggers are added around the perimeter, with an angle ≤60° to the ground. A patterned steel plate 1 is laid on top, and the steel plate is welded and fixed to the keel. The joints are fully welded to prevent misalignment. The steel casing 3 is vertically hoisted to the center of the support platform using a crane. A rubber pad is added between the bottom of the casing and the steel plate to reduce vibration. The perimeter is fixed with steel clamps. The drilling rig is hoisted to the platform, and the drill rod and mud circulation system are connected. The center of the drilling rig is checked to be aligned with the axis of the casing. A graded loading test run is conducted. After confirming that there is no abnormal deformation of the support, formal drilling construction begins.

[0031] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
