Description

    FIELD OF THE INVENTION
  • The present invention relates to water engineering and reinforced concrete poling board integrated underground engineering, such as embankment, harbor waterway, artificial island, roadway bridge, sluice, culvert and water channel, and particularly to a hydraulic sliding insertion panel and its using method.
  • DESCRIPTION OF THE RELATED ART
  • The conventional hydraulic insertion of reinforced concrete poling board generally has the following shortcomings: 1. Hydraulic thrusting is the only means, so that sinking is slow and hard to bypass and eliminate the underground obstacles; 2. it is hard to form an integrated structure in the connection portion that has high strength and tightness. Although Chinese patent ZL200420040430.8 SLIDEWAY AND SLIDE PLATE OF A HYDRAULIC SLIDING INSERTION PANEL provides a connection technique, no inner cavity is formed in the connection portion of two panels that cannot be sealed by the water isolation path. Thus grout injected into the bottom of the connection portion of two panels cannot normally return to the top of the board due to leakage, thus the expected tightness of the connection portion cannot be achieved. 3. Each pile board and existing hydraulic sliding insertion panel has to be provided thereon with a flow guide tube, a sprinkler pipe and a sprinkler head, which substantially increases the cost in fabrication and steel consumption. And the high pressure water supply pipe needs to be connected once for each poling board during construction, thus extending the period spent for construction and increasing cost.
  • SUMMARY OF THE INVENTION
  • The object of the invention is to provide a hydraulic sliding insertion panel that can be quickly sunk into the stratum and effectively remove underground obstacles and the method of using the same. The prior art disadvantages and shortcomings may be effectively overcome by employing the connecting technique in which a connection between two boards which has a strength and tightness fully meeting the performance index of the board body and employing the constructing technique in which the engineering boards with no flow guide tube and water jetting pipe can in combination with a tool board sink into the stratum. In this way, the board sinking speed is increased, the capability of eliminating the underground obstacles is enhanced, the amount of steel consumed is reduced, time spent for loading and unloading of water supply pipe for each board is shortened, and the high strength integral connection between boards is achieved, so as to achieve the object of speeding up construction, reducing the engineering cost, enhancing safety and stability, and altering the constructing pattern of existing engineering construction.
  • The hydraulic sliding insertion panel according to one aspect of the invention comprises a reinforced concrete poling board, a flow guide tube vertically set in the poling board, a water distributing pipe communicating with the flow guide tube horizontally set in the bottom of the poling board, a slideway provided on the one side and a slide plate provided on the other side of the poling board respectively, and erection loops and inbuilt preset steel bars on the top of the poling board. The hydraulic sliding insertion panel further comprises vertical water isolation paths set in the reinforced concrete poling board on the two sides of the slide way and the slide plate.
  • In one aspect, the lower end of the reinforced concrete poling board has a level, tapered or unilaterally tapered shape. The water distributing pipe has an upper half embedded in the reinforced concrete poling board and a lower half provided with a plurality of sprinkler holes arrayed in an uniformly spaced jigsaw pattern, each of the sprinkler holes having a diameter of 2 to 8 mm, with a dispensing area of 9 to 36 cm2 on the cross section of the reinforced concrete poling board. Each of the water isolation paths is a groove vertically set on the side surfaces of the reinforced concrete poling board and having a cross section of semicircle, a semi-square, a semi-rectangle, a semi-rhombus or a semi-ellipse, and after two adjacent poling boards are sunk in the stratum, the two corresponding water isolation paths of the two adjacent poling boards will present a complete circle, square, rectangle, rhombus or ellipse shape. There may be one water isolation path on each side of the slideway and slide plate or one water isolation paths on either side of the slideway and slide plate, or no water isolation path is provided. The slideway is a finished steel product having a perpendicular recess, such as square steel, channel steel, angle steel and steel slab. The slide plate is an I-steel or T-steel, one half in the slideway and slide plate and another half exposed outside, which slides in the slideway while the reinforced concrete poling board is being sunk. In another aspect, the reinforced concrete poling board is designed to comprise a tool board structure having a metal cutting blade set in the bottom of and in parallel with the water distributing pipe. In still another aspect, the reinforced concrete poling board is designed to comprise a simplified engineering board structure only comprising a slideway, a slide plate and water isolation paths thereon. In still another aspect, the reinforced concrete poling board is designed to have an inverted T-shaped structure that is slim in the upper portion and thick in the lower portion.
  • A hydraulic sliding insertion panel and its using method according to the present invention comprises: (A) hoisting the reinforced concrete poling board by a lifting apparatus and sinking the reinforced concrete poling board into the stratum by hydraulic jet via the flow guide tube and the distributing pipe, then sinking another reinforced concrete poling board into the stratum by inserting the slide plate of another reinforced concrete poling board through the recessed hollow square steel slideway of the poling board that has already been sunk in the stratum, characterized by further comprising: (B) integrated connection between various boards, first flushing the water isolation paths by flushing pipes, then setting down a strip bag and infusing grout so as to form an inner cavity between the boards completely isolated from the exterior; (C) lowering a grout pipe into the hollow square steel in the inner cavity, and filling the inner cavity with grout from bottom to top so that an integrated structure of steel bar reinforced concrete with sandwiched steel sheet is formed in the connection portion; (D) casting the top crossbeam on site or not, when casting, casting after bonding together with the preset steel bars and the newly added crosswise steel bars to form a crosswise entity, and step (D) may be omitted depending on the specific project, in which case no steel bar is preset on the reinforced concrete poling board.
  • In another aspect, the step (A) may be performed as follows: cutting the stratum with a tool board having a metal cutting blade, removing the tool board, and sinking a simplified engineering board in the stratum cut by the tool board, wherein cutting and sinking is alternately carried out, with other steps being the same as (B), (C) and (D), so as to finally form the simplified engineering board integral structure in the stratum.
  • In still another aspect, the step (A) is implemented entirely by the tool board, with other steps being the same as (B), (C) and (D), so as to finally form the simplified engineering board integral structure in the stratum.
  • The present invention provides the following advantages over the prior art:
  • 1. The hydraulic sliding insertion panel has the functions of hydraulic cutting, integrated connection, on-site crossbeam casting and vertical lifting, may have the pile board form a firm integrated structure underground. And the connection between two boards may have a strength and tightness reaching or surpassing the performance of the board itself. So the problems, such as seepage, leakage and poor connection, generally involved in various existing piling engineering projects are avoided.
  • 2. The water distributing pipe is used to properly distribute water flow in high pressure. Thus the sinking speed in a normal condition is substantially increased. And the tool board is capable of effectively removing or bypassing the underground obstacles such as tree stems and stones.
  • 3. The conventional underground integrated structure is for the present built by digging earth, bonding steel bars and casting in position. Owing to the development of an unique underground poling boards connection technique and the special advantage of providing for the strength and tightness in the inter-board connection portion reaching or surpassing the performance of the board itself, the present construction technique allows a number of poling boards to be precast on the ground for implementing the integrated underground engineering, which are sequentially sunk into the stratum in a constructing manner similar to that of building toy bricks, and formed into an integrated structure by implementing integrated connection technique therebetween. For example, engineering projects like underground culverts and transportation tunnels may be carried out in this way. By replacing the conventional construction mode with the present invention, the construction speed is greatly increased, the engineering cost is lowered, and the safety and stability thereof is assured so as to provide a new way for reinforced concrete poling board underground integrated construction.
  • 4. No more need to install the flow guide tube, sprinkler head and sprinkler pipe on each poling board. So cost in fabrication and steel consumption is reduced.
  • 5. No more need to connect the water supply pipe once for each poling board during construction. So time and cost are saved.
  • 6. The top preset steel bars are bonded together with additional horizontal steel bars, and then cast into a crossbeam, so as to strengthen the connection.
  • 7. In the case when the hydraulic sliding insertion panel is used as supporting structures, e.g. bridge or pier piles, the portion of the poling board to be sunk into the stratum may be precast into an inverted T-shaped structure. Besides, the gap between the board and stratum is filled by grout injected by the flow guide tube within the board, immediately after that portion has been sunk into the stratum, so as to form an integrated concrete structure to substantially increase the bearing capacity of each board thus reducing the cost.

  • DETAILED DESCRIPTION OF THE EMBODIMENTS
  • With reference to FIGS. 1 to 18, a hydraulic sliding insertion panel comprises a reinforced concrete poling board 1, a flow guide tube 2 vertically set in the poling board, a water distributing pipe 3 communicating with the flow guide tube horizontally set in the bottom of the poling board, a slideway 5 provided on the one side and a slide plate 6 provided on the other side of the poling board respectively, and erection loops 8 and inbuilt preset steel bars 9 on the top of the poling board 1. The hydraulic sliding insertion panel further comprises vertical water isolation paths 7 set in the reinforced concrete poling board on the two sides of the slide way and the slide plate.
  • The lower end of the reinforced concrete poling board 1 has a level, tapered or unilaterally tapered shape. The water distributing pipe 3 has an upper half embedded in the reinforced concrete poling board and a lower half provided with a plurality of sprinkler holes 10 arrayed in an uniformly spaced jigsaw pattern, each of the sprinkler holes having a diameter of 2 to 8 mm, with a dispensing area of 9 to 36 cm2 on the cross section of the reinforced concrete poling board. Each of the water isolation paths 7 is a groove vertically set on the side surfaces of the reinforced concrete poling board and having a cross section of semicircle, a semi-square, a semi-rectangle, a semi-rhombus or a semi-ellipse. After two adjacent poling boards are sunk in the stratum, the two corresponding water isolation paths of the two adjacent poling boards will present a complete circle, square, rectangle, rhombus or ellipse shape. There may be one water isolation paths 7 on each side of the slideway 5 and slide plate 6, or one water isolation paths on either side of the slideway and slide plate, or no water isolation path is provided. The slideway is a finished steel product having a perpendicular recess, such as square steel, channel steel, angle steel and steel slab. The slide plate is an I-steel or T-steel, one half in the slideway and slide plate and another half exposed outside, which slides in the slideway while the reinforced concrete poling board is being sunk. The reinforced concrete poling board is further designed to comprise a tool board structure having a metal cutting blade 4 set in the bottom of and in parallel with the water distributing pipe. In still another embodiment, the reinforced concrete poling board is further designed to comprise a simplified engineering board structure only comprising a slideway, a slide plate and water isolation paths thereon. Whether there is a water isolation path or not depends on the specific project. The reinforced concrete poling board may have an inverted T-shaped structure that is slim in the upper portion and thick in the lower portion, when it is designed to support a heavy weight, such as when building bridge poles.
  • A hydraulic sliding insertion panel and its using method according to the invention comprises: (A) hoisting the reinforced concrete poling board by a lifting apparatus and sinking the reinforced concrete poling board into the stratum by hydraulic jet via the flow guide tube and the distributing pipe, then sinking another reinforced concrete poling board into the stratum by inserting the slide plate of another reinforced concrete poling board through the recessed hollow square steel slideway of the poling board that has already been sunk in the stratum. The method further comprises: (B) integrated connection between various boards, first flushing the water isolation paths by flushing pipes, then setting down a strip bag and infusing grout so as to form an inner cavity 14 between the boards completely isolated from the exterior; (C) lowering a grout pipe 15 into the hollow square steel in the inner cavity, and filling the inner cavity with grout from bottom to top so that an integrated structure of steel bar reinforced concrete with sandwiched steel sheet is formed in the connection portion; (D) casting the top crossbeam 16 on site or not as required by the engineering. When casting on site, casting is performed after bonding together with the preset steel bars 9 and the newly added crosswise steel bars to form a crosswise entity, and step (D) may be omitted depending on the specific project, in which case no steel bar is preset on the reinforced concrete poling board.
  • In another embodiment, the step (A) may be performed as follows: cutting the stratum with a tool board having a metal cutting blade, removing the tool board, and sinking a simplified engineering board in the stratum cut by the tool board. Cutting and the sinking is alternately carried out, with other steps being the same as (B), (C) and (D), so as to finally form the simplified engineering board integral structure in the stratum.
  • When the construction of the hydraulic sliding insertion panel is performed in water, particularly under sea, after the above steps (A) to (D), a further step may be added depending on the specific project, which is carried out by throwing rubbles on both sides of the hydraulic sliding insertion panel, so as to form a revetment 17 of a certain height for further increasing the stability and anti-fracture strength thereof.
  • In case the hydraulic sliding insertion panel is used as a supporting structure, e.g. a bridge or pier pile, when the poling board is precast on the ground, the portion to be sunk underground is spread out bilaterally to form an inverted T-shaped structure through bonding the steels bars and on site casting concrete. As a result, such a board after being sunk into the stratum has a side friction area and terminal bearing area far greater than that of a conventional board. Besides, the gap between the board and stratum is wholly filled with grout to form an integrated concrete structure to substantially increase the bearing capacity of each board. Thus the base of the board is shortened, and the construction cost is lowered.
