Description

Technical Field

[0001] The utility model belongs to the technical field of guide wall templates, and particularly relates to a bite-type row of piles concave arc-shaped guide wall template. Background Art

[0002] In the field of construction, interlocking pile rows are a common engineering method and are widely used in foundation pit support projects. Interlocking pile rows refer to continuous pile walls with soil retaining and water stopping functions formed by interlocking concrete piles.

[0003] Interlocking piles are suitable for foundation pit support projects with large foundation pit depth, complex surrounding environment, poor geological conditions, high groundwater level, surrounding buildings that are sensitive to settlement or no precipitation conditions. They can be used in various geological conditions such as fill, silt, clay, silt, sand and rock, especially saturated soft loess, silt or other soft soil layers, with good applicability and economic benefits.

[0004] In order to ensure that the precise positioning and verticality of the interlocking pile row meet the requirements of the specification and provide necessary support for the construction of the drilling rig, it is necessary to build the guide wall before the interlocking pile construction. The guide wall plays the role of positioning, guiding and locking, which is directly related to the hole accuracy and quality of the interlocking pile. The guide wall should be made of cast-in-place reinforced concrete, and the quality of the guide wall formwork support is the prerequisite for the construction of the interlocking pile.

[0005] At present, most of the guide wall formworks are made of wood or steel formworks. Such formworks are complex to assemble, time-consuming and labor-intensive, and have poor economic efficiency. There are also integrated steel formworks made of angle steel and arc steel plates welded together. Such steel formworks are mainly suitable for straight sections, and still need to be assembled in large quantities at corners and arc sections. Both of the above formworks have major defects, low efficiency, and it is difficult to ensure the construction quality. Utility Model Content

[0006] In view of the above-mentioned problems, the purpose of the utility model is to provide an interlocking pile row concave arc guide wall formwork, which utilizes the omnidirectionality of the circle and connects circular arc plates and cylindrical formworks through repeated combination and connection at intervals, without the need for on-site loose assembly, and can effectively solve the formwork problems in the above-mentioned different sections.

[0007] The technical solution of the utility model is: a bite-type pile row concave arc-shaped guide wall template, comprising:

[0008] A plurality of circular arc plates, all of which are column tubes with the same specifications;

[0009] A plurality of concave arc plates, each of the concave arc plates comprises two symmetrically arranged first arc plates, the arc openings of the two first arc plates are opposite to each other, and the concave arc plates further comprise two symmetrically arranged second arc plates, the arc openings of the two second arc plates are opposite to each other, and the second arc plate is connected and arranged between the two first arc plates;

[0010] The curvatures of the first arc plate and the second arc plate are the same as the curvature of the circular arc plate.

[0011] Furthermore, a positioner is provided on the circular arc plate.

[0012] Furthermore, the locator comprises:

[0013] Two steel bars are vertically and cross-arranged on the upper end of the circular arc plate, and the intersection point is located on the central axis of the circular arc plate;

[0015] Furthermore, a vertical groove is provided on the side surface of the first arc plate near the second arc plate, and the lower end of the vertical groove is open for inserting the circular arc plate.

[0016] Furthermore, the thickness of the circular arc plate, the first arc plate and the second arc plate are all 10-20 mm.

[0017] Furthermore, the diameter of the steel bar is 8-15 mm.

[0018] The construction method of the utility model: after the site is leveled and compacted, a total station is used to measure and place the pile positions of the interlocking piles. According to the measured pile positions, the position of the circular arc plate is first determined. The circular arc plate is accurately positioned by a positioner and is placed at a corner or an arc. After the position is determined, four ground anchors are symmetrically driven into the circular arc plate. The ground anchors are made of threaded steel with a diameter of 20 mm and a length of 1.0 m, which are driven into the soil by no less than 0.5 m. Similarly, multiple circular arc plates are positioned in sequence, and then a concave arc plate is inserted from top to bottom between two cylindrical templates so that the circular arc plate is inserted into the vertical groove. The position of the concave arc plate is checked. After determining that it is accurate, two ground anchors are symmetrically driven into the connection between the concave arc plate and the circular arc plate. The template is symmetrically fixed by the ground anchors to ensure that the layout is consistent with the installation position and that the template does not run during the pouring process.
