2. Description of the Related Art For example, soft soil is generally used as landfill after being mixed with a solidifying agent to improve the soil quality. Examples of methods for improving the soil quality of soft soil include, for example, a premixing method (Conventional example 1) and a premix method (Conventional example 2).
Since the outlines of these construction methods will be described below, first, in the pre-mixing treatment construction method according to Conventional Example 1, soft soil is cut out from the hopper onto the feeder belt conveyor, and the feeding direction of the feeder belt conveyor is changed. Cement, which is a solidifying agent, is supplied to an intermediate position, and a soft soil is obtained by passing the feeder belt conveyor to a tripper belt conveyor having a chute in which round steel is arranged, and a chute of the tripper belt conveyor. It is a method of mixing soil and cement evenly to improve the soil quality, and providing the soil-improved soil with improved soil quality as landfill soil. Note that the soft soil whose soil quality can be improved by this premixing treatment method is sand, earth and sand, clay, and the like.

Next, in the premix method according to Conventional Example 2, the super soft soil is received in the hopper, cement milk as a solidifying agent is injected into the super soft soil received immediately before being supplied to the kneader, and the kneader is used. This is a method in which the mixture of agitated and mixed ultra-soft soil and cement milk obtained is pumped to a landfill site by a pressure pump via a pipe.

First, as described above, the premixing method according to Conventional Example 1 can be applied to improve the soil quality of soft soil such as sand, earth and sand, and clay. However, it cannot be applied to dredged ultra-soft soil such as mud. The reason why this pre-mixing method cannot be applied to ultra-soft soil is that not only is the transfer point from the feeder belt conveyor to the tripper belt conveyor and the chute of the tripper belt conveyor clogged with ultra-soft soil. This is because it is difficult to uniformly mix ultra-soft soil and cement.

Next, the premix method according to Conventional Example 2 is suitable for improving the soil quality of ultra-soft soil because it is a method of pressure-feeding with a pressure-feeding pump. However, not only is the kneader expensive, but a part of the mixture adheres to the pumping pipe and gradually grows, resulting in increased pumping power and difficulty in pumping, or being included in the dredged soil in the pumping pipe. Foreign matter (stones,
(Steel materials, etc.) may become clogged and pressure feeding may not be possible.
Preliminary removal work of foreign matter is required. That is, in addition to the increase in initial cost and pretreatment cost, there is a problem to be solved that it is difficult to improve the soil improvement efficiency because the operation of the equipment has to be stopped for cleaning the inside of the pumping pipe.

Therefore, at the exit portion of the belt conveyor 1, the wavy movement of the conveyor belt 4 further injects the solidifying agent S into the super soft soil mixed with the solidifying agent S, so that the ultra soft soil is solidified more. By mixing with the agent S, the soil quality of ultra-soft soil is further improved. Of course, the groove made in the mud mud 10 by the groove backfilling mechanism 9 is backfilled by the groove making mechanism 8. By the way, in this case, the drive motors are provided on both sides of the crankshaft, but the drive motors may be provided on either one of them. A cleaner for removing the mixture of the ultra-soft soil and the solidifying agent S scattered and adhered to the back surface of the conveyor belt 4 is provided at the exit of the belt conveyor 1, while the cleaner adheres to the inner wall of the splash shielding cover 5. It is preferable to provide a water jet device for removing the mixture of the super-soft soil and the solidifying agent S that are present.

Hereinafter, the operation mode of the belt conveyor 1 will be described by taking as an example the case where the ultra-soft soil is hed mud dredged by a dredger, and the hed mud dredged by the dredger is loaded into a hopper (not shown). The sewed mud is supplied from the hopper to the inlet portion of the belt conveyor 1 in a fixed amount. The mud 10 is carried by the carrying belt 4 of the belt conveyor 1, and the solidifying agent S such as cement milk or cement is continuously jetted from the nozzle 6 to the surface of the mud being carried. When the mud 10 having the solidifying agent sprayed on the entire surface is conveyed to the intermediate portion of the belt conveyor 1, the end portions are arranged so as to be alternately higher and lower along the conveying direction of the mud 10. Since the carrier belts 4 move in a wavy manner by the end carrier rollers 2b and 2b 'of each of the carrier rollers 2, the mud 10 is forcibly flowed during the transportation in the intermediate portion of the belt conveyor 1 and the mud 10 The solidifying agent S is mixed with the soil to improve the soil quality of the mud 10.

When the mud 10 mixed with the solidifying agent S is conveyed from the intermediate portion of the belt conveyor 1 to the outlet portion, this time, by the grooved disk 8b of the grooved mechanism 8 at this intermediate portion. For grooving of the groove and the grooving mechanism 8 of the groove caused by the groove backfilling mechanism 9 using the groove backfilling disk 9b and the groove backfilling disk 9b of the groove backfilling mechanism 9 By repeating backfilling with the disk 8b and new grooving, a larger amount of the solidifying agent S is mixed with the mud 10 to further improve the soil quality of the mud 10.
The injection amount of the solidifying agent S from the nozzle 6 is determined by the test result, and should be changed depending on, for example, the softness of the dredged mud 10 and the required strength of the improved soil.

As described above, according to the belt conveyor 1 according to the embodiment of the present invention, the tripper belt conveyor is used for mixing the ultra-soft soil and the solidifying agent as in the premixing method according to the conventional example 1. Not a configuration. Therefore, the mud 10 which is super-soft soil does not become clogged at the transfer point from the feeder belt conveyor to the tripper belt conveyor and the chute of the tripper belt conveyor, and the wavy movement and the grooving of the conveyor belt 4 occur. By the grooving of the mechanism 8 and the groove backfilling of the groove 9
The solidifying agent S is surely mixed with the solidifying agent S, and the soil quality of the mud 10 is improved.

Further, unlike the premix method according to Conventional Example 2, the mud 10 and the solidifying agent S are not mixed by a kneader, but the mud 10 and the solidifying agent S mixed by the kneader are mixed. Since the solidifying agent S is mixed and mixed in the mud 10 being conveyed by the belt conveyor 1 instead of the method in which the mixture is pressure-fed by a pressure pump, an expensive kneading machine is not required and the mud 10 Since it is not necessary to remove foreign matters such as stones and steel materials in advance, it can contribute to the reduction of equipment cost and mud treatment cost, and the cleaning of the inside of the pressure-feeding pipe is also unnecessary, improving soil improvement efficiency. Not only can the landfill work be carried out stably, but the mixing performance of the mud and the solidifying agent is also excellent, so there is no need for ground improvement work after landfill, which is an extremely effective effect.
