Description of the invention (l) <Technical field to which the invention belongs> The present invention relates to a method for discharging and grouting of a through-hole dredging pipe at the bottom of a pile, in particular, a method for removing the mud at the bottom of the pile in advance and filling it Construction method of grouting and pressure grouting to improve the lack of mud at the bottom of the pile and strengthen the stratum at the bottom of the pile to increase its bearing capacity. Technology>; In general, when a ring pile is drilled and the bearing capacity is not easy to build at the bottom of the pile, the mesh reinforcement cage 1 1 slurry is used to discharge it. Due to the post-strength, the pile bottom does not bear the load, but the pile bottom and rock formation slurry method. In the same building, bridge, or important equipment, the common type foundation pile is used as the bearing foundation pile of the building, but such foundation pile sleeve rolls, impact foundation piles, etc.) are often caused by the bottom of the pile to the pile tip. ^ ^ 0 F τ Ding 0 Ξ) the situation is reduced, > the amount of child traps should be said, "increased 'affects the safety of the structure and even clears the lack of liquid in the construction method 11 2 is not uniform Figure 2 space can not be Adopt (reverse mud removal to make the foundation pile huge. When the poor 1 steel 2 the irrigation 3 is not or mixed to improve 0, the concrete system is set to improve the pile before mining the mud phase to improve the irrigation and productivity. The purpose of producing a sink is to form a hard and hard 'you' ni (such as closed irrigation) when it is not easy to use the slurry at the bottom of the grouting tube. Therefore, as shown in Figure 1, Phenomenon of the foundation piles shown) pinch, this reached changed to grams As shown in the figure, due to the inability of the pile 3 to carry water without a bottom bearing, Shen Shiruo's currently described pile bottom is tied to the foundation pile mud grouting liquid, and the mud-synchronous mixing method achieves that the rock layer 1 mud is limited by 567270 V. Description of the invention (2) 'A " <Contents of the Invention> ^ The main purpose of the invention is to provide the _ seed pile bottom through-hole drainage pipe of the sludge grouting construction method, tied to the foundation pile One or more sets of grouting pipes and sludge pipes are set in the steel reinforced cage, so that the top of the pipe protrudes from the ground by about 1.0M, and the pipe body is placed on the bottom of the foundation pile with the steel reinforced cage. Among them, the grouting pipe The bottom is provided with a one-way valve 'and the bottom section of the dewatering pipe is provided with uniformly distributed perforations. When the dewatering pipe = perforation section is filled with stuffing, the dredger can be removed when the pile bottom is sinking. The filling is removed, and then clear water is injected from the grouting pipe or any of the drainage pipes, so that the sediment is discharged from the drainage pipe due to pressure, and then the grouting pipe or any of the drainage pipes is used for filling and pressure grouting. Pouring cement slurry or solidified material to increase the bearing capacity of the pile bottom. Another object of the present invention, A through-hole sludge pipe is provided at the bottom of the sludge pipe. 'This through-hole sludge pipe can economically and effectively achieve the purpose of removing sediment. If the sludge pipe has no through-hole design, it is only at the bottom of the pipe. Through holes are provided. When the mud is thick and the bottom of the pipe is 1 · 0m to 2 · 0m, the removal and removal of the mud is not easy, which will reduce the effectiveness of the mud at the bottom of the pile.
因此本發明係於排泥管底段適當長度約1 · 5 m至2 • 5 m ’設有透孔可供水、沉泥或水泥漿液之進出，為避 免基樁施工過程中受雜物或混凝土阻塞，乃預先於排泥管 管内透孔段設有填充物，此填充物不會因浸水或水壓影響 而分解、破壞，另考慮施工的方便性及可行性，此填充物 為軟質低透水性之材料如水泥、皂土、砂之拌合物、保麗 龍、泡棉等材料，可用輕型鈷桿及清水报容易的將填充材 料清除導溝。當樁底沉泥厚度為5 〇公分或1 〇 〇公分、Therefore, the present invention relates to a proper length of the bottom section of the drainage pipe of about 1 · 5m to 2 · 5m '. It is provided with through holes for water, mud or cement slurry to enter and exit. In order to avoid debris or concrete during the foundation pile construction process, Blocking is provided with a filler in the perforated section of the drainage pipe in advance. This filler will not be decomposed or damaged due to the influence of water immersion or water pressure. In addition, considering the convenience and feasibility of the construction, this filler is soft and low-permeability. Materials such as cement, bentonite, sand mixes, polystyrene, foam and other materials can be easily removed from the filling channel with a light cobalt rod and clear water. When the sediment thickness at the bottom of the pile is 50 cm or 100 cm,

Refer to the steps below four, five, six, and seven: The top of the dredging pipe 4 2 is lightened by the through hole 42 1 of the steel brush 5 42 above the drill pipe 5 so that the mud 3 at the bottom of the pile is cleared 2 1 It can be discharged upwards, and it can also be discharged by mud. When the mud dredging pipe 4 2 leaves, the water flow can be divided vertically by π, so as to reach the grouting pipe 4 1 which is to be tied to the group of drilling foundation piles 4 or more. Wait for the grouting pipe 4 and wait for the drainage pipe 4 2 respectively to fill the filling 4 (Polyuron, foam, etc.), the one-way valve 4 1 of the tube 4 1 and when the grouting stops, the single backflow 'When the concrete pipe is filled with the mud pipe 4 2, the concrete slurry and the eight diagrams' are used in the present invention to remove the filler 4 2 1 from the construction-type drill pipe 5 (as shown in FIG. 8), and then the grout pipe 4 1 is used for water. When punching and draining from any of the sludge pipes 4 2 4 to clear water, it means piles

Description of the invention (4) The bottom sediment 3 is shown in Figure 5). 2. From the bottom of the pile at the same time, this method can also be used. 3. The front slurry 2 will be even, which means 4. Increase the length and formation fluid to the bottom of the pile to increase the foundation pile. The design of the mud dredging pipe in the upper hole, the pouring cement, sincerely pray to the bureau to grout the pipe 4 1 'The water is drained from any row of mud to the side of the pile, and the pile has been drained 4 2 Characteristics, suitable for the bearing capacity of the surrounding spreading (grouting, and its construction works know the construction method and improve the bottom of the pile, the present invention makes the sediment at the bottom of the pile, a novelty for review, has been removed already. Stop the water injection, at this time, the bottom of the pile will be filled with water slurry 2 to expel (inject cement, while one side of the slurry 2 is sealed with mud, and the top of the pile is pressed to seal the bottom of the pile. The top cover of the slurry 2 cannot be poured into the cement mud pipe 4 2 Pipe 4 2 irrigation & slurry 2 and the pressure when the cement is filled with water at the top of the pipe to achieve the figure 8) Other drainage pipe sequence, the bearing capacity of the cement liquid and the mud is set at the bottom of the pile to strengthen the pile properly The creation of sex is given by Zhunzhuan Figure 6) 2 slurry. The water is expelled from the sludge pipe 2 (closed as shown in the figure, and then force grouting is used, and a layer of sludge for the layer improvement is sealed because the liquid 2 can be evenly mixed and injected, of course, during the process, 4 2 overflows 7). The foundation piles are made for cement slurry purpose, and the pipes are closed for pouring. The lack of cloth at the bottom of the pile allows the grouting tube in the ribbed dragon to discharge the rain when it can discharge the bearing capacity of M ☆ & Zushi + the bottom of the pile is evenly distributed, which is a practical application for a patent application.
