Description
Technical Field
The utility model relates to the field of building construction, in particular to a joint device for a glass fiber rib ground connection wall female slot.
Background
The traditional joint method is to adopt a common I-shaped steel plate for welding, and the glass fiber reinforced plastic underground diaphragm wall needs no steel due to the fact that a shield is penetrated downwards, so that the joint needs to be constructed by a locking pipe. The concrete method is that after the grooving of a unit groove section is finished, a steel reinforcement cage is placed downwards, the end part of the groove section is hoisted by a crane or a jack hoisting frame, then the steel reinforcement cage is hoisted and poured with concrete, a fore shaft pipe is pulled out after the concrete is initially set, and the fore shaft pipe hoisting operation method comprises the following steps: firstly, the jacking machine is hung above the fore shaft pipe, and the fore shaft pipe is sleeved by the jacking machine and placed on the guide wall. The hoop force is applied to the hoop arm ring through the horizontal jack, the hoop arm ring tightly holds the fore shaft pipe, the vertical jacking and pulling device is used for jacking and pulling, then the horizontal jack is used for releasing pressure, the hoop arm ring is loosened, the fore shaft pipe is hung by a crane so as not to fall down, the vertical jacking and pulling device is contracted, and the hoop system is recovered to the initial position. And repeating the process until the required pulling force of the fore shaft pipe is less than the pulling force of the crane, and pulling out the fore shaft pipe by the crane. So that the ends of the unit groove sections are semicircular. The fore shaft pipe in the underground continuous wall has the advantages that the two adjacent groove ends are well embedded and connected, the water seepage phenomenon is avoided, and the purpose is to stabilize the reinforcement cage of the continuous wall and ensure that concrete turbulence is well controlled. However, the following problems occur:
1. the slot wall is not perpendicular, causing a shift in the position of the fore shaft: due to the reasons of machinery and manpower, the problem that two ends of the formed groove wall are not perpendicular always exists at the lower part, so that when the fore shaft pipe is arranged, the fore shaft pipe cannot be arranged according to the position of a preset sample, and the width of the wall and the downward placement of the reinforcement cage are influenced. Meanwhile, the rear surface of the fore shaft pipe is too large, so that the workload of earth backfilling is increased, and the problem of slurry leakage is easily caused.
2. The locking notch pipe is not fixed stably, so that the locking notch pipe is inclined: the fixed of fore shaft pipe is fixed including the upper end and the lower extreme is fixed: the lower end is fixed by lifting a section of the fore shaft pipe by a crane to enable the fore shaft pipe to freely fall and be inserted into the soil to be fixed, and the fixing method enables the lower end of the fore shaft pipe not to generate large displacement generally. The upper end is fixed and is generally driven into the pilot sleeper through the gap between the fore shaft pipe and the pilot wall, and is solved by the channel steel diagonal bracing, and the generation of the displacement of the fore shaft pipe can be basically avoided. The most used in practical construction is to pull the fore shaft pipe vertically upwards with 10 tons of force for 100 tons of crane, and when the fore shaft pipe is deviated, the fore shaft pipe can be returned with reverse force. The disadvantage of this method is that when small displacements occur, the forces in the opposite direction are small and cannot be reacted, so displacements are unavoidable and it is difficult for a 100 ton crane to find a suitable position when site conditions do not allow.
The first case is upper end deviation, the occurrence frequency is more, and the second case is lower end deviation, and the occurrence probability is lower. The occurrence of the sludge interlayer seriously affects the construction quality and can cause serious water leakage problem. The interlayer is prevented from inclining the fore shaft pipe, and the wall is brushed up by taking a thought when brushing the wall.
3. Problem of pulling out the fore shaft tube: in order to avoid using a hydraulic jacking frame when pulling out the fore shaft pipe, the fore shaft pipe is often pulled out when concrete is not poured, so that the pulling out is not impossible, the initial setting time of the concrete is only required to be mastered, and the pulling out cannot be mastered well in actual operation. The pipe drawing is too early, concrete is easy to leak slurry and even collapse, and serious quality problems of the diaphragm wall are caused; the tube drawing is too late, causes the hasp pipe "to inlay" easily and dies in the ground even wall, causes the shield to pass, loses the original effect of glass fiber muscle, causes certain loss to progress and economy.
4. Problem of backfill behind the fore shaft pipe: after the fore shaft pipe is placed down, the fore shaft pipe cannot be tightly attached to a soil body, a certain gap always exists, earthwork backfilling must be carried out, otherwise, concrete bypasses the fore shaft pipe, and a great obstacle is caused to the construction of the next continuous wall. However, the gaps are small and filled with slurry, so that the backfill is not easy to compact.
