Description

Technical Field

[0001] The present invention relates to the field of anti-seepage and water-stopping technologies in underground projects, and in particular to a construction technology for constructing a vertical underground continuous thin film water-stopping wall by means of a composite membrane material, specifically an integrated machine for drilling, grooving and film planting and an integrated drilling, grooving and film planting method. Background Art

[0002] In underground projects, in order to ensure the overall safety of the building, "anti-seepage" and "water stopping" are very critical links; water-stop curtains, as a technical means of waterproofing and isolation, have been widely used in engineering practice.

[0003] Earlier, the water-stop curtain process mainly adopted the form of concrete grouting, but a large number of practical processes have shown that its construction quality is easily affected by geological characteristics and there are many uncontrollable and unknown factors in the construction process: for example, bubbles and sand appear on the concrete surface during the grouting process, and even the interaction between cement slurry and the surrounding soil, resulting in uneven internal stress. Although the rotary jet pile forming process can make the grouting more uniform, it will inevitably produce many bubbles in the soil, resulting in uneven pressure distribution, making the grouting strength unable to be guaranteed, and the water-stop effect cannot meet the requirements. The equipment of deep mixing technology has problems with uneven mixing and groundwater flow, which can easily lead to local pile erosion when the cement soil has not yet formed or the strength is insufficient. In addition, in the formation with good permeability, due to the large water level difference inside and outside the pit, the water-stop curtain will have local leakage and damage. In addition, due to the construction depth, construction quality, construction site and site engineering geological conditions, the loss of cement soil slurry in the water-stop curtain is very likely to cause broken piles and vulnerable areas. The compaction grouting and freezing method is only applicable to specific soil conditions and has great limitations. However, if the underground continuous wall only serves as a water-stop curtain, it becomes over-constructed due to the limitations of its construction technology.

[0004] In recent years, in some construction projects and contaminated soil treatment, membrane materials such as high-density polyethylene membrane (HDPE membrane) and sodium-based bentonite waterproof blanket have been used as anti-seepage membranes and vertically implanted underground (hereinafter referred to as "planted membranes") as anti-seepage structures for groundwater or pollutant isolation, and have achieved certain application results. The membrane structure has high economy and impermeability due to its small thickness and dense polymer structure. This new waterproof curtain technology effectively avoids the common problems of traditional cement soil waterproof curtain technology.

[0005] When implementing the new waterproof curtain using the above-mentioned membrane planting technology, it is first necessary to use a trenching machine or other large equipment to dig the soil and form trenches, set up multiple continuous unit trench sections, and then use membrane laying equipment to vertically lay the anti-seepage membrane in the unit trench sections, and finally connect the unit trench sections to form an underground continuous waterproof curtain. This process has the defects of low construction efficiency and discontinuous process, which are specifically reflected in the following aspects: 1. The traditional grooving and film planting process mainly includes the steps of trenching, mud wall grooving, frame film spreading and lowering. Among them, grooving and film planting are two independent working conditions, which require the equipment of grooving and film laying for front and back construction. Therefore, the work efficiency of the whole process is low (< / d), and the construction depth generally does not exceed; after increasing the construction depth, the work efficiency will be further reduced.

[0006] 2. Relying on the ground wall slotting machine to dig slots and plant membranes, it is necessary to construct the guide wall first, and the slotting machine will have a construction surface after the maintenance is in place. In addition, the slotting width of this method is generally greater than, while the thickness of the membrane itself is generally not more than. After the membrane is placed, a large amount of mud in the slot needs to be replaced or solidified, which is poor in economic efficiency, cumbersome procedures, and waste mud will cause environmental pollution.

[0007] 3. Various anti-seepage films are generally made of flexible materials. When they are lowered into a trough section filled with mud, they are affected by external forces such as mud buoyancy and trough wall resistance. It is difficult to control the verticality of the film after grooving and then planting the film, which directly affects the anti-seepage effect of the water-stop curtain after the film is planted.

[0008] Therefore, it is necessary to develop a new type of integrated equipment for opening holes, sawing grooves and film planting to meet the requirements of the "film planting" process. Summary of the invention

[0009] The purpose of the present invention is to overcome the above-mentioned defects and to propose a construction device that can complete the three operations of drilling, sawing grooves and planting membranes at one time, synchronously and continuously to realize an underground membrane water-stopping continuous wall.

[0010] In order to achieve the above object, the present invention is achieved in the following ways: A machine for drilling, sawing grooves and planting films, comprising a walking chassis with tracks, a drilling module, a sawing groove module and a planting film module; wherein: The drilling module includes a drilling tool assembly and a double mast system.

The drilling tool assembly includes a hole-drilling drill for drilling holes. The hole-drilling drill is driven by the power head 2 of the double mast drive system to perform a hole-drilling step of drilling underground to a designed depth. The hole-drilling step is used for subsequently inserting a hollow connecting column 4 underground. The saw slot module includes a flexible rope saw 5, a traction system, a down-the-hole traction drill 7 with a steering traction wheel 6, and a hole guide wheel 3 arranged on the mast 1 and located beside the mast 1. The traction system includes a pair of double-drum rotating mechanisms 8 controlled by differential linkage and capable of independent movement. The flexible rope saw 5 reciprocates under the traction of the double-drum rotating mechanism 8. When the flexible rope saw 5 reciprocates, one side drum of the double-drum rotating mechanism 9 actively pulls one end of the flexible rope saw 5, and the other side drum actively pulls the other end of the flexible rope saw 5. The end implements passive traction with adjustable tension. At the same time, the flexible rope saw 5 is also connected through the steering traction wheel 6 of the down-the-hole traction drilling tool 7. When the down-the-hole traction drilling tool 7 is driven by the double mast drive system and vertically penetrates into the connecting column 4, the flexible rope saw 16 and the double drum rotating mechanism are guided by the hole guide wheel 3 and synchronously fed with the up and down movements of the down-the-hole traction drilling tool 7 and ensure that the flexible rope saw 5 is always located beside the axis of the connecting column 4, and then cooperates with the slurry gas positive and reverse circulation system to realize the underground cutting saw groove function; The film planting module includes an impermeable membrane 10 and a film spreading frame 11.

The working platform 13 is arranged on the walking chassis; the walking chassis is used to transport the working platform equipped with each module to the designated construction area, and the precise positioning of the buried hole of the connecting column 4 is achieved through the cross-boat assembly 15 and the movable mast system. After the working platform is lifted as a whole and adjusted to a horizontal state by relying on the lifting cylinder 14, the drilling module, the groove sawing module and the film planting module work in turn, thereby realizing integrated hole opening, groove sawing and film planting operations.

[0011] The drilling tool assembly of the hole-making, groove-sawing and film-planting machine also includes a guide rod 16, which is used to lengthen the hole-making drill in the drilling tool assembly or the down-the-hole traction drill 7 in the traction system so that the two can reach the working depth required by the design; the guide rod 16 is a continuous type, and the requirements of different hole-making or guiding depths can be met by splicing multiple guide rods 16 to each other and further splicing them with the hole-making drill or the down-the-hole traction drill 4.

[0012] The described all-in-one machine for drilling, groove sawing and film planting has a double mast system comprising a pair of masts 1 which are vertically arranged on a working platform and can move relative to each other to shorten or increase the distance between them. Thus, the drilling tool assembly and the guide rod 16 can adapt to the drilling operations and film planting guiding operations of different widths of thin film water-stopping continuous walls under the guidance of the mast system.

[0013] The double-drum rotating mechanism 8 in the traction system of the said hole-drilling, groove-sawing and film-planting integrated machine respectively implements active traction on one end of the flexible rope saw 5 and passive traction with adjustable tension on the other end, wherein the drums on both sides are in a group of left and right spirals, used in pairs, and move independently in the same direction, with the rope coming out from the bottom, and cooperating with the hole guide wheel 3 to ensure that the flexible rope saw 5 is always located beside the axis of the connecting column 4; at the same time, the flexible rope saw 5 has a vertical feed redundancy under the differential action of the double-drum rotating mechanism 8, and also in its Under the action, the horizontal tension force is maintained, and finally horizontal reciprocating cutting is formed; at the same time, the down-the-hole traction drill 7 is fed synchronously with the up and down movements of the guide rod 16, and the flexible rope saw 5 is pulled to form a vertical up and down feed; at the same time, the slurry and pressure gas are transported to the bottom ends of the down-the-hole traction drill 7 on both sides along with the drill assembly, and a jet and flushing force is formed at the bottom of the cutting groove of the connecting column 5, thereby lifting and discharging the debris at the front end of the down-the-hole traction drill 7; the underground hole-forming and continuous bottom-clearing sawing steps are realized.

[0016] The integrated hole-drilling, groove-sawing and film-planting machine is provided with a steering traction wheel 6 in the down-the-hole traction drill 7.

During the operation of the drum, the double-drum rotating mechanism always plays a pulling role and maintains the predetermined tension of the flexible rope saw 5. Step 8: When the drilling module is working, a faucet is set on the mast 1 and the gas source and the slurry water source are connected to the hollow guide rod 16 through an external connection; thus, when the guide rod 16 is moving downward, the bottom of the groove is sprayed and flushed to realize the slurry gas positive circulation or reverse circulation operation; Step 9, when the guide rod 16 descends to a predetermined depth, the traction cleat release trigger 31 is activated to disconnect the unhooking device 22 from the traction cleat release trigger 31, so that the traction cleat 32 is separated from the down-the-hole traction drill 7, and the traction cleat 32 and the anti-seepage membrane 10 are left at the designated position; in the double-drum rotating mechanism on both sides of the traction mechanism, the drum at one end releases the rope head of the flexible rope saw 5, and the drum at the other end recovers the flexible rope saw 5; Step 10, pouring curing agent into the connecting column 5 through the guide rod 16, sealing the anti-seepage membrane 10 and the port of the connecting column 4 until the ground; Step 11: The double mast system pulls up the guide rod 16 and the down-the-hole traction drill 7 respectively, cleans the guide rod and the drill assembly, and the operation is completed.
