Problems solved by technology

The combined steel sheet pile formed by H steel pile and steel sheet pile is widely used in foundation pit support due to its better bending resistance and construction performance. In the area where it is used as a non-permanent pile, the combined steel sheet pile can be At present, the pile extraction work of H steel piles and steel sheet piles in the combined steel sheet pile is generally carried out by large-scale high-frequency vibration equipment. These pile extraction equipment are not only expensive, but also in the process of pile extraction. Generate large vibration and noise pollution, cause damage to surrounding buildings, and affect the normal life of surrounding residents, especially for buildings that have just completed construction, because the concrete has not yet reached the curing period, and its strength has not reached its maximum value. The stabilization produced by the pile pulling equipment will have a certain impact on the strength of these buildings

Embodiment 1

[0074] The operation platform for the pull pile will be described below.

[0075] See Figure 1 - Figure 3 ,exist figure 1 In the arrow marked as m, the arrow indicates the M axis, the direction of the arrow Y1 is the first direction, and the direction of the arrow Y 2 is the second direction. The first direction and the second direction are opposite to the opposite direction, and each is perpendicular to the m axis.

[0076] The operating platform is used to pull out the steel pile in the combined steel plate pile wall. The operating platform includes a support table 110 having an upper surface and a lower surface of the opposite side, and a continuous seam 120 penetrates the upper surface and the lower surface, and the support table 110 is cut into a first partition 111 and the second. Division 112, the continuous seam 120 extends in the direction of the m axis, and through the opposite sides of the support table 110, the M axis parallel to the upper surface.

[0077] The upper s...

Embodiment 2

[0090] A pilot device comprising an operational platform in Example 1, and a first pushing machine and a second piler.

[0091] The first pile driver will be described below.

[0092] See Figure 7 - Figure 12 In the present application, the axial direction refers to the extending direction of the axis, for example, the first axis direction refers to the extended direction of the first axis, and the second axis direction refers to the extended direction of the second axis, and is pushed.

[0093] The first pile driver is used to unplug the H steel pile, which includes a support frame 60 including a rectangular force frame 61 and a support plate mounted at the bottom of the force frame 61. 62. The top of the force frame 60 is open, and a steel pile aisle 65 for use in the h-steel pile 800 is formed on the support plate 62; two first first in the inner cavity 63 of the support frame 60; The clip pile jack 70, the two first clip pile jack 70 is located on both sides of the steel pile ...

Embodiment 3

[0120] A method for extraction of a combination of steel sheet piles, piles using pulling apparatus embodiment is performed, comprising the steps of:

[0121] (1) recovering steel pile H:

[0122] See Figure 1 - Figure 17 Firstly the first pile drivers supported on the platform, the first lift jack on each side of the web of the H steel piles, steel piles and H is inserted into the channel steel piles, a steel pile above the ground in H the body defines an end portion of the pile hole.

[0123] Adjusting the first lift jack A second extension length of the piston rod, the inner and outer Pile Holes Pile Holes and Piles body facing, with pin holes through the outer pull the pile, the pile body and the inner hole Pile Holes the steel piles H hanging on the lifting member and the second elongate rod a, H steel piles driven upwardly until the maximum elongation a second piston rod, after, removal of the pin, so that departing from the steel pile H lifting members.

[0124] A second pi...

Abstract

The application discloses an operation platform for pulling piles, which includes a support platform, and a continuous seam cuts the support platform into a first subsection and a second subsection; the continuous seam includes 6-12 sequentially connected The steel sheet pile seams are referred to as the first steel sheet pile seam and the second steel sheet pile seam respectively, and the first steel sheet pile seam and the second steel sheet pile seam are arranged alternately; the notch of the first steel sheet pile seam faces the first direction , the notch of the second steel sheet pile slit faces the second direction; the first direction and the second direction point oppositely; corresponding to each first steel sheet pile slit, an H steel pile slit is provided. The application also discloses a pile-extracting device, which includes a first pile-extractor, a second pile-extractor and the aforementioned operating platform. The present application also provides a method for pulling out a combined steel sheet pile. Utilizing the application, the static pile extractor can be directly supported on the operating platform for operation, reducing noise pollution in the area and the impact on newly-built buildings, especially avoiding the impact on the strength of the newly-built buildings.

Description

Technical field [0001] The present invention relates to an operation platform, a pulling device and a pull pile method for combining steel sheet pile piles. Background technique [0002] After the end of the foundation pit support construction, the various piles used in the support foundation pit must be removed. First, the piles have been avoided in the ground, and thereby causing pollution on environmental underground soil and soil. The second is to recycle materials, reduce construction cost. The combined steel sheet pile formed by the H-steel pile and the steel sheet pile is widely used in the foundation pit support due to better bending and construction performance, and the combined steel sheet pile can be used as a non-permanent trap. Recycling, at present, the pile of the H-steel pile and steel sheet pile in the combined steel sheet pile is generally carried out by a large-scale high-frequency vibration, but these piles are not only high, but in the process of pulling pile...
