Abstract

The invention provides an excavate-subside stack double wall method to construct the underground continuous wall. There are the working steps: (1) Install guide grooves and guide walls at the predetermined location. (2) Allocate the first continuous wall unit, double pre-fabricated, at the bottom layer between the guide walls. (3) Proceed the drilling grooves process after Install the driller: use driller equipped with water injector and dipping pump to work and let the lower wall unit subsided downward followed by the reducing groove volume. (4) Stack the upper wall unit of continuous wall section upon the lower wall unit from the bottom layer. (5) Install driller again to drill grooves. Return to the step (3) and employ driller to proceed drilling so that the upper wall unit can be further subsided downward. As several wall units have stacked up to predetermined depth, grout concrete from the top to complete the first working section of continuous wall. (6) Back to the step (2) and start another unit operation until the continuous walls are completed connected. In the weak or sandy loose soil structure, as starting grilling grooves or grouting, it probably collapses and increases the working difficulty. This construction method for continuous walls can effectively solve the problem to have better quality of finished continuous walls and waterproof function. Not only could reduce the consumption of labors and working period, but also could increase the constructing efficiency, lower the noise, vibration and air pollution, and won't pollute the underground water and water and sewage conduit.

Description

A7 B7 V. Description of the invention (I) The present invention relates to a method for digging and sinking double-walled underground continuous burial walls, in particular, it refers to the use of drilling equipment consisting of a water jet M and a draw spring to perform trenching. The iron excavator works, and at the same time, the wall of Xue Xia's unit gradually sinks into the trench, and then the unit structure wall above the continuous wall is above the unit wall below the bottom. After the trench is drilled until the unit wall body reaches a predetermined depth, a portion of concrete can be poured from the top surface, which is the operating stage of the continuous wall in the first paragraph; this is repeated until the continuous wall is completed; Μ Constructing continuous walls as the construction method above * For weak or sandy structural soil, due to the soil structure, continuous wall trench excavation or hole collapse during gambling can effectively solve the construction difficulties, and make the completed continuous wall With better engineering quality and water-stopping effect, not only can reduce the waste of manpower and man-hours, but also can improve work efficiency and can reduce noise, vibration, air pollution, and stable pollution of groundwater quality and sewage, etc. Environmental harm public, and because the use of composite construction method for application, and having better water resistance and other properties. // Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (谙 First read and read the notes on the back and then write this page) Press. Generally, the traditional underground continuous wall operation method is first tied to the ground area where the foundation is excavated. A deep trench is set in the surrounding area, and the deep trench is provided with a pre-assembled reinforced cage (or a PC board body implanted into a prefabricated state). A spare PC board) is placed in a deep trench, and then concrete is poured from above (or a mixed curing agent is injected from both sides of the PC board to harden it to form a wall with the PC board), but this construction method is suitable for Those who have a relatively dull and weak soil layer, because of the characteristics of their soil structure, have a hole collapse disaster when they dig trenches or surround concrete, which prevents them from completing smoothly. In addition to often causing construction blockage, interruption, and even The embarrassment of the project shutdown, and the loose paper size applies the Chinese National Standard (CNS) A4 (210X297 mm). Printed by the Consumers Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. A7 B7. 2) The instability of sand on the trench wall 'common is the collapse of soil and rock on the wall', which has a great impact on the grip of the steel cage structure and the strength of the concrete '. Moreover, in the face of weak soil layers, changes cannot be determined. 'When the trench is dug, it will have an impact on the structure of the adjacent soil layer', and even cause ground subsidence. In addition, the conventional underground continuous wall construction method still has the following shortcomings: 1. Due to the structure of the conventional continuous wall, it is formed by successively placing several successive unit wall bodies formed as described above * The continuous wall of the group is because there are no good components that can be combined between the two unit wall bodies, so that there is a gap at the joint between the two unit wall bodies. The requirements of watertightness and strength of the overall comprehensive wall surface. 2. As mentioned above, the gap between the two unit walls formed by the two units is caused by the tight connection between the rotor and the method. The gap naturally forms the diversion of the splashing water. Cii. 5-: Therefore, successive continuous walls are still produced. The situation of water splashing causes the danger of construction and the trouble of water leakage in the wall during future use. 3. The traditional method of pouring concrete after placing a reinforced cage in a deep trench is to reserve a gutter hole on the reinforced cage. After pouring the concrete once at the filling gate, the concrete will solidify to form a unit wall; However, due to the width of the trench and its extremely deep depth (usually more than 10 meters), and because it is filled in the trench filled with stable fluid, the steel cage is not only susceptible to contamination by the stable fluid, but also its gripping power. Because the wall soil and mud are easily mixed into the concrete, the strength of the concrete is affected, and the strength and quality are reduced. This paper size is applicable to China National Standard (CNS) A4 specifications (210X297mmt (please read the precautions on the back before writing this page privately)

1T Λ7 B7 Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the Invention (d) 4. Also, after the conventional PC board is inserted into the trench, the solidified solution prepared by mixing is injected into the trench to fill the bag Cover both sides of the PC board so that it can form a joint wall shape after curing. However, because there is no good connection mechanism between PC boards, and only the curing solution is used for bonding, it may be due to the proportion and time error when the curing solution is mixed and prepared. Vulnerable to change, thus affecting the overall structural strength. 5. Furthermore, the traditional continuous wall is formed by inserting a steel cage into the excavation groove and refilling the concrete; however, often due to poor site conditions and poor construction management control, vertical accuracy and smoothness of the concrete wall surface are caused. In addition, the thickness of the protective layer of the reinforcement is insufficient. Among them, in addition to easily causing wall cracks and rebar erosion, and jeopardizing the function of the retaining wall, it also increases the burden of construction and work. ZZ ;, 6. Because the traditional underground continuous wall is in a trench filled with stable fluid, the volume formed by the integral molding of the reinforced cage (or PC board) is too large, which makes it difficult to control the quality of the wall in addition to construction difficulties. Therefore, it is often necessary to build another wall on the inside of the excavated wall to decorate the rough or possibly cracked underground continuous wall wall surface, which not only reduces the volume of the basement volume, but also requires multiple reinforcements, which increases labor and labor. Costs such as time and material use are contrary to economic principles. For this reason, the present inventor has intensively studied and carefully designed and improved in view of this, and invented the present invention. The main purpose of the present invention is to provide a weak or sandy structure soil, which can effectively solve the construction difficulties, and make the finished wall with better engineering quality and water-stopping effect, not only can reduce manpower 2.
