Description

Technical Field

[0001] The invention relates to the field of building construction, in particular to a cement pile stabilizing device used in the field of construction. Background Art

[0002] Cement pile is a method used to reinforce saturated soft clay foundation. It uses cement as a curing agent and a special mixing machine to force the soft soil and curing agent to mix deep in the foundation. A series of physical and chemical reactions between the curing agent and the soft soil are used to harden the soft soil into a high-quality foundation with integrity, water stability and a certain strength. The reinforcement depth usually exceeds 5m, the dry reinforcement depth should not exceed 15m, and the wet reinforcement depth should not exceed 20m. The cement slurry pressed into the soft soil is forced to mix with the surrounding soft soil with rotating mixing blades to form a mud reinforcement body. The basic principle of cement reinforced soil is based on the physical and chemical reaction process of cement reinforced soil. It is different from the hardening mechanism of concrete. Due to the small amount of cement, cement reacts in the presence of a certain active medium - soil. The hardening speed is slow and the action is complex. After cement hydrolysis and hydration to form various water compounds, some of them undergo ion exchange and granulation as well as hardening reaction, which greatly improves the strength of cement soil.

[0003] In the process of construction, cement piles are often used to reinforce the foundation. The general way of piling is to drill holes in the ground first, then place the cement piles in the holes, and hammer the cement piles into the ground with external machinery. However, in the process of cement piling, the stability of the cement piles is poor, and it is easy to tilt during piling, which is inconvenient to operate, thus affecting the subsequent use of the foundation and reducing the stability of the foundation. Summary of the invention

[0004] The purpose of the present invention is to overcome the problems raised by the above-mentioned background technology and to provide a cement pile stabilizing device for use in the construction field to avoid external machinery hammering the cement pile into the ground. However, during the cement pile driving process, the cement pile has poor stability and is prone to tilting during pile driving, which is inconvenient to operate and affects the subsequent use of the foundation, reducing the stability of the foundation.

[0005] The purpose of the present invention is mainly achieved through the following technical solutions:

[0006] A cement pile stabilizing device used in the construction field comprises a back plate, two slide grooves are provided on the side wall of the back plate in the horizontal direction, a matching slider is slidably provided at both ends of each slide groove, a swing rod is rotatably provided on the side wall of the back plate, and the swing rod is located between the two slide grooves, and a pull rod is hinged at both ends of the swing rod, two clamping plates I are slidably provided on the side wall of the back plate with the swing rod as the symmetry axis, the back plate located on the same side of the swing rod in the vertical direction is connected to the two sliders, a cavity is provided inside each clamping plate I, a hydraulic cylinder is provided in the cavity, the output end of the hydraulic cylinder is hinged to one end of the swing rod, a connecting block is provided on the side wall of the back plate away from the clamping plate I, and a connecting block is provided on the connecting block. A clamping assembly for clamping cement piles is provided on the block, and through holes I connected to the cavity are provided on opposite side walls of two clamping plates I, and a round rod is movably provided in the cavity, and the round rod movably penetrates the cavity and extends outward, and two half gears are rotated in the cavity with the round rod as the axis of symmetry, and two spur racks are slidably provided on the inner wall of the cavity with the round rod as the axis of symmetry, and the half gears located on the same side of the round rod are meshed with the spur racks, and clamping plates II are provided on opposite end faces of the two spur racks, and each clamping plate II movably penetrates the through hole I and extends outward, and two straight rods are hinged on the outer wall of the round rod with the axis of the round rod as the axis of symmetry, and the straight rods located on the same side of the axis of the round rod are hinged to the half gears.

[0007] The purpose of the present invention is to solve the problem that during the construction process, the foundation is reinforced by cement piles. The general piling method is to first drill holes on the ground, then place the cement piles in the holes, and hammer the cement piles into the ground by external machinery. However, during the cement piling process, the cement piles have poor stability and are prone to tilting during piling, which is inconvenient to operate, thereby affecting the subsequent use of the foundation and reducing the stability of the foundation.

[0008] The present invention provides a device for fixing cement piles. First, when the device is working, it is first fixed on the vertical column of the external machine through two clamping plates I. When the external machine hoists the cement column, the cement pile is auxiliary clamped by the clamping assembly for clamping the cement pile. By fixing the device on the vertical column of the external machine, the construction workers can use the hydraulic hammer to drive the cement pile into the ground to provide auxiliary support. First, the back plate can be temporarily fixed on the vertical column of the external machine by two clamping plates arranged on the back plate, and then the clamping plates are fixed on each clamping plate. Ⅰ is provided with a cavity inside, and a through hole Ⅰ connected to the cavity is provided on the opposite side walls of the two clamping plates Ⅰ. A round rod is movably provided in the cavity, and the round rod movably penetrates the cavity and extends outward. Two half gears are rotated in the cavity with the round rod as the symmetry axis, and two spur racks are slidably provided on the inner wall of the cavity with the round rod as the symmetry axis. The half gears located on the same side of the round rod are meshed with the spur racks. Clamping plates Ⅱ are provided on the opposite end faces of the two spur racks. Each clamping plate Ⅱ movably penetrates the through hole Ⅰ and extends outward. Two straight rods are symmetrically hinged on the outer wall of the round rod. The straight rod located on the same side of the round rod axis is hinged with the half gear. When the opposite side walls of the two clamping plates I are in contact with the vertical column of the external machine, another group of clamping plates II arranged on the opposite side walls of the two clamping plates I can fix the back plate on the vertical column of the external machine to prevent the back plate from shaking on the vertical column of the external machine, thereby causing the cement pile to have poor stability during the process of driving the cement pile into the ground by the hydraulic hammer device on the external machine. The pile is prone to tilting during driving, which is inconvenient to operate, thereby affecting the subsequent use of the foundation and reducing the stability of the foundation. The round rod is a hydraulic telescopic rod. When When the hydraulic telescopic rod is contracted, the output end of the hydraulic telescopic rod will pull the gear to rotate through the straight rod, thereby pulling the two spur racks to move towards each other, so that the clamping plate I can be stabilized on the vertical column of the external machinery through the clamping force of the two clamping plates I and the clamping plate II arranged inside the clamping plate I, and the back plate can be firmly fixed on the vertical column of the external machinery to prevent the back plate from shaking on the vertical column of the external machinery, thereby causing the auxiliary support of the clamping assembly to the cement column to be unstable, thereby causing the cement pile to shake on the soft soil under the action of the hydraulic hammer of the external machinery.

[0009] Furthermore, the clamping assembly includes a cross bar, which is fixedly arranged on the end face of the connecting block. Through holes II are opened at both ends of the cross bar, and a rotating rod is rotatably arranged in each through hole. Both ends of the rotating rod are movable through through hole II and extend outward. A two-way hydraulic cylinder is arranged on the outer wall of the cross bar in the horizontal direction, and one output end of the two-way hydraulic cylinder is hinged to a rotating rod. Arc plates are arranged on the two rotating rods, and the centers of the circles where the two arc plates are located are coaxial. By providing a cross bar on the end face of the connecting block, in the initial state, that is, before the piling work begins, the rotating rods are not parallel to each other, and the angle between the two rotating rods and the cross bar is an obtuse angle. When the hydraulic hammer on the external machine hammers the cement pile, the two rotating rods move towards each other under the fixed action of the bidirectional hydraulic rod on the cross bar, so that the inner wall of the arc plate provided on the rotating rod contacts the outer wall of the cement column, thereby providing auxiliary support for the cement pile and preventing the cement pile from tilting during the process of hammering the cement pile into the ground by the external machine, which makes the operation inconvenient and affects the subsequent use of the foundation and reduces the stability of the foundation. The cement pile and the vertical column of the external machine are combined into a relative whole by the device to prevent the cement column from shaking and the cement pile from tilting when the hydraulic hammer hammers the cement pile.

[0010] Furthermore, a plurality of blind holes are provided on the inner wall of each splint, and a push rod is movably provided in each blind hole, and the push rod movably passes through the blind hole and then extends outward, and a rubber wheel is sleeved on the outer wall of the push rod, and one end of the rubber wheel is connected to the outer wall of the push rod, and the other end of the rubber wheel is connected to the inner wall of the blind hole, and a rubber wheel is rotatably provided on the end surface of the extended end of each push rod. By providing a blind hole on the inner wall of each splint, a push rod is movably provided in each blind hole, and a rubber wheel is rotatably provided on the end surface of the extended end of each push rod, the cement column can smoothly pass through between the arc plates when the cement pile is driven by an external machine, thereby preventing the wear of the arc plate caused by the transitional contact between the cement pile and the arc plate, which causes the service life of the arc plate to be too short.

[0011] Furthermore, a rectangular hole I is provided on each rotating rod, a moving rod is slidably provided in the rectangular hole I, both ends of the moving rod are movable through the rectangular hole I and then extend outward, the moving rod is hinged to the arc plate, an external thread is provided on the extended end of the moving rod, and a nut matching the external thread is provided on the extended end of the moving rod. By providing a rectangular hole I on each rotating rod, a moving rod is slidably provided in the rectangular hole I, both ends of the moving rod are movable through the rectangular hole and then extend outward, the moving rod is hinged to the arc plate, an external thread is provided on the extended end of the moving rod, and a nut matching the external thread is provided on the extended end of the moving rod, different types of cement piles can be adapted, and different cement piles can be auxiliary supported, so as to prevent the cement piles from tilting during the process of hammering the cement piles into the ground by external machinery, which makes the operation inconvenient, thereby affecting the subsequent use of the foundation and reducing the stability of the foundation.

[0012] Furthermore, a plurality of rectangular holes II are provided on the side walls where the splint II and splint I contact the external mechanical vertical column, and a guide wheel is rotatably provided in each rectangular hole II, and the outer wall of each guide wheel partially protrudes from the rectangular hole II. By providing a plurality of rectangular holes II on the side walls where the splint II and splint I contact the vertical column, and a guide wheel is rotatably provided in each rectangular hole II, and the outer wall of each guide wheel partially protrudes from the rectangular hole II, it can play a guiding role. When the cement pile is hammered by an external machine, the displacement of the device and the cement pile is consistent, so that the cement pile provides good auxiliary support when being hammered into the ground, and prevents the cement pile from tilting due to the hammering of the external machine during the process of being buried in the ground, which makes the operation inconvenient, thereby affecting the subsequent use of the foundation and reducing the stability of the foundation.

[0013] In summary, compared with the prior art, the present invention has the following beneficial effects: another group of clamping plates II arranged on the opposite side walls of the two clamping plates I can fix the back plate on the vertical column of the external machine to prevent the back plate from shaking on the vertical column of the external machine, thereby causing the cement pile to have poor stability during the process of driving the cement pile into the ground by the hydraulic hammer device on the external machine, and it is easy to tilt during pile driving, which is inconvenient to operate, thereby affecting the subsequent use of the foundation and reducing the stability of the foundation. A rubber wheel is rotatably provided on the end surface of the extended end of each push rod, and by arranging the rubber wheel, When cement piles are driven by external machinery, cement columns can pass smoothly between the arc plates, preventing the wear of the arc plates due to the transitional contact between the cement piles and the arc plates, which causes the service life of the arc plates to be too short. When cement piles are hammered by external machinery, the displacement of this device is consistent with that of the cement piles, so that the cement piles can provide good auxiliary support when being hammered into the ground, preventing the cement columns from tilting due to the hammering of external machinery during the process of being buried in the ground, causing inconvenience in operation, thereby affecting the subsequent use of the foundation and reducing the stability of the foundation.
