The present invention provides a construction method of the backhoe machine for the heavily karstic water-rich urban shallow buried tunnels, comprising the following steps:

• S1: measuring and positioning the excavation tunnel area and geological prospecting using a leading geological forecasting system;
• S2: dredging the rock by means of a backhoe machine and the cutting teeth thereon and performing a primary discharge of the slag stones by means of a separate slag discharge device of the excavating machine;
• S3: When the cinder blocks accumulate to a certain extent, a load behind the excavator machine is carried out by means of an excavating machine, by means of a transporter or a belt conveyor conveyed the cinder blocks inside a collection funnel of the shaft and then through the hopper or other vertical conveyors to the ground be lifted;
• S4: After the excavator machine completes an excavation cycle, it is retracted for a certain distance behind the tunnel surface, then the anchor rod is used and the steel beams are erected;
• S5: performing the construction of an initial lining of the shotcrete, sealing the excavated rock face to complete the initial support;
• S6: performing the casting construction of the secondary lining concrete to form a forming tunnel.

With the above steps, excavation is performed by layer-removing the rock layer by means of a console excavator machine, thereby relatively little influence on the environment to improve the safety and quality of the construction, at the same time the construction efficiency is improved, and the construction cost is reduced.

Prior to step S2, a preliminary drilling or geological drilling is performed to explore whether there is a karst cave in a particular area in front of the tunnel surface, with a positive result showing the location and size of the karst cave, drainage and drainage Clogging and filling are performed by pouring and then excavation is performed, and in the case of a negative result, excavation is immediately performed.

With regard to the selection of the model of the excavator machine, the model of the excavator machine can be determined on the basis of parameters such as the total cutting height, width and rock hardness, eg: the total cutting height is 5.73 m, the width is 6.62 m and the rock hardness 30MPa up to 60MPa, based on the parameters an excavator machine with the model number EBZ260 can be selected.

When excavating, a method of cutting by means of a backhoe machine can be used after the backhoe machine reaches the correct position, a groove is cut horizontally from the bottom portion of the tunnel surface, the excavator machine is moved forward, and again reaches the correct position, after which Cutting head a from bottom to top and from left to right circularly running cutting, when cutting load the rake pawls of the airfoil section simultaneously the cut slag in a first transport conveyor, then transferred from the first transport conveyor to a second transport conveyor, the second transport conveyor loads the Slag immediately into a slag discharge vehicle and convey it out of the cave, after completing the excavation from the floor section to the head section, secondary trimming is performed to get a precise design cut t to achieve. When locally hard rocks having a hardness of more than 100 MPa exist, soft rocks in the vicinity can be excavated first, so that large blocks of rocks fall off to reduce the excavating difficulty and the consumption amount of the incisors. The backhoe machine uses a cutting method in that cutting first starts with the bottom portion and the above portions are cut off stepwise with a cutter path which is S-shaped or Z-shaped upwardly circulating from left to right.

As in 1 In the actual application, hard rocks can be cut off by means of a cutting head rotating to the right, first a rock is cut from right to left of the bottom section, then the rock moves from left to right from bottom to top or from right to left from above Stepwise cut below, in a rock with better developed joints, the rock should be cut stepwise along the joint direction of the rock.

For the rocks of different hardnesses, different incisors can be made, and the incisors are appropriately spirally distributed to ensure better cutting ability and self-cleaning function of the machine, after actual operating conditions, an optimum cutting head can be selected to improve the construction efficiency. If there is a hard rock locally, a cutting head with a small diameter can be selected which has a large cutting force and a better ability to break the rocks to reduce the excavating difficulty and the consumption amount of the cutting teeth.

In the dredging process, a backhoe and underbody control for the backhoe machine should be carried out. Since the tunneling has a complex environment, a construction method using the excavating machine with dredging without explosion is used. During the excavating process of the excavator machine, the machine can not be arranged for measurement all the time, so the For this purpose, a laser pointing device can be installed on a provisionally closed part of the tunnel, before the dredging the direction of the laser pointing device is adjusted, so that the laser is blasted onto the tunnel surface to guide the dredging, simultaneously the distance of the laser pointing device to the tunnel surface is appropriately set by the linear shape of the tunnel, the above method can better control over-dredging and sub-dredging to reduce spattering of the mixed materials, at the same time saving costs, thereby providing an instruction function for the Control of dredging of the tunnel reached.

In order to improve the construction environment in the cave and to reduce the work intensity in step S3, a small excavating machine and a tipper are arranged at the rear part of the excavating machine, which cooperate with the excavator when unloading the slags. The excavator machine loads the cut slag through the rake pawls on the conveyor belt and transfers it to the tail section of the excavator machine, the excavating machine conveys the slags to the dump truck to convey it to the outside, thereby excavating the excavator machine in time.

After trimming for the contour of the tunnel surface in step S4, an erection work is to be carried out by means of a self-made initial support stand for the excavated parts, the self-made primary stand has a length of 6m, a width of 5m and a height of 5m and is l18 T -Stahl produced, this consists of an upper work surface and a lower work surface, before dredging the stand is first pushed by the excavator to the rear of the excavated work surface, after complete excavation of the tunnel surface, the excavator machine is withdrawn, at the same time the stand by means of the excavator to the work surface pushed the stand, after ensuring the stability of the stand, the excavator machine is withdrawn.

As in 2 shown, the excavator machine has a relatively large size and can just run in the tunnel. If the excavator machine still remains on the tunnel surface after excavation of a tunnel surface, the expected working efficiency of the excavating machine can not be achieved, at the same time the erection and the concrete spraying of the tunnel surface are severely impaired, due to which an adequate conversion between the respective working steps in the tunnel can be carried out in order to ensure the construction progress and full use of the excavating machine and to fully develop the working efficiency of the excavating machine, at the same time, emphasis should be put on the maintenance of the excavating machine in this process, to avoid that mechanical damage leads to unnecessary waste of time, The concrete implementation method is as follows: Two excavator machines are each arranged at a left center position and a right center position to perform dredging. After completion of excavating by the excavating machine, the excavating machine pushes the initial support stand to the proper position, then the excavator machine returns to the cross passage and turns around, entering each of the left extension and right extension to perform dredging, simultaneously performing erecting and concrete spraying work in the left center position and right center position, in order to essentially ensure that in the time period for erecting and concrete spraying the excavator machine can dredger another tunnel surface ready to ensure a coupling between the respective steps in the tunnel. When the excavation distance of the inverted arch of a tunnel surface satisfies the relevant requirements, the excavator machine enters a different tunnel surface after the dredging of a tunnel surface has been completed to perform excavation of the inverted arch. If the other tunnel surface also meets the requirements, a similar method is used for the alternating work.

In a preferred embodiment, in the pit design in the digging process of the excavating machine, in step S2, ground monitoring is constantly arranged to monitor the data and perform dynamic feedback, with the excavation length being controlled by each excavation cycle.

In a preferred embodiment, in step S2, in the construction process of the excavating machine, aeration and exhaust dedusting operation is carried out, wherein the ventilation is a press-in ventilation and the suction is a suction by means of a dedusting machine, since the back-up machine uses a large amount of dust produced, the dust is blown into the tunnel using a conventional press-in ventilation. In the dredging process of the excavator machine, the inside of the tunnel is always in a state of high dust concentration. In order to ensure that during the construction process of the tunnel the dust does not affect the employees and that there is a good construction environment in the tunnel, the requirements for the construction work environment can not be met by the spraying device on the cutting head of the excavating machine Effective dust control measures should be taken, such as adding a 22KW dedusting fan behind the excavator machine, changing the original press-in vent to a combination of press-in vent and suction vent. The location of the dedusting fan is determined as follows:

unter der Annahme, dass die Schnittfläche des Tunnels 38 m² beträgt, kann ein wirksamer Ansaughub des Entstaubungslüfters von etwa 18,6 m erzielt werden. In der tatsächlichen Lüftungskonstruktion beträgt die Menge an eingepresster Frischluft 6-8 m/s, der Durchmesser der Ansaugöffnung beträgt 1,2 m, die Luftgeschwindigkeit des Einpresseinlasses beträgt etwa 6 m/s, während der Durchfluss der Ansaugöffnung des Entstaubungslüfters 4 m/s, der Durchmesser der Ansaugöffnung 0,6 m und Luftströmungsgeschwindigkeit der Ansaugöffnung 14,1 m/s beträgt. Die Wirkung des lokalen Unterdruckes ist sehr offensichtlich. In the tunnel, the dedusting fan can absorb a large amount of dirty air through the suction port, filters the dust in dirty air through its own internal dedusting device and releases the fresh air to trap the dust in the tunnel. The strong air flow in the suction port of the dedusting fan will form a local negative pressure zone in the environment. The presence of the local negative pressure zone plays an important role in the confluence of dirty air, the effective intake stroke of the confluence through the suction port is calculated as follows: $L_e=3\sqrt{S}.$

assuming that the cut surface of the tunnel 38 m ² , an effective suction stroke of the dedusting fan of about 18.6 m can be achieved. In the actual ventilation design, the amount of injected fresh air is 6 - 8th m / s, the diameter of the suction port is 1.2 m, the air velocity of the injection inlet is about 6 m / s, while the flow rate of the suction port of the dedusting 4 m / s, the diameter of the suction port is 0.6 m and the air flow velocity of the intake port is 14.1 m / s. The effect of the local negative pressure is very obvious.

This is also the basis of the confluence of the dedusting fan. In order to control the dust as much as possible within the smallest possible tunnel zone, it should only be ensured that the effective intake stroke can cover the tail section of the machine body. Because of this, there is a better effect when the dedusting fan is located at a position about 18 m behind the backhoe machine. With an adjusting calculation according to the actual situation, it can be found that the air pressure of the tunnel fan is 1.5 times as much as the air pressure of the dedusting fan, moreover, an optimal dedusting effect can be achieved when the dedusting fan is positioned at a distance of 30 m far from the tunnel surface.

• c: Infrared water exploration: 20 points are arranged on the tunnel surface, each forming a cycle for 20 meters, and the depth of exploration 25 m, and wherein the overlap length between two adjacent exploration holes 5 m is.

Since the tunnel is in high karst and high water content area, the difficulty in the excavation process is higher in comparison to ordinary areas, and an appropriate cutting method should be found in the context of the result of the advanced geological prediction system. From the results of the survey, when dredging the lines where the exploration results in front of the tunnel surface are abnormal, a dredge method is usually used as follows: from the abnormal position, a small hole is drilled, then the hole becomes spiral from one circle to another extended to ensure that the dredging process minimizes disruption to the front containment rocks, thereby preventing unpredictable mud and water bubbling and other accidents.

The present invention has a wide range of uses and is applicable to building sites with relatively complex construction environments and greater safety risks, e.g. The routes or tunnels pass through the buildings, rivers or roads, etc., laterally or underneath, as well as similar tunnel projects in which explosive dredging can not be used for a variety of reasons.
