Description

The adjustable concrete end mould of Tunnel Second Lining width
Technical field
The utility model belongs to Tunnel Engineering secondary lining technical field, in particular it relates to which a kind of Tunnel Second Lining is wide Spend adjustable concrete end mould.
Background technology
In Tunnel Engineering, surrounding rock supporting is generally divided into preliminary bracing and secondary lining.Secondary lining, refer in tunnel Under conditions of carrying out preliminary bracing, the inner lining built with materials such as concrete, to reach its support reinforcement, optimization route, peace Drainage system, aesthetic appeal, the convenient effect that the facilities such as communication, illumination, monitoring are set are filled, to adapt to modernize tunnel construction It is required that.
Tunnel Second Lining is usually concrete or reinforced concrete structure.Lining trolley is the secondary lining of constructing tunnel process The special equipment that must be used in block, for the concrete- liner construction to tunnel inner wall.The construction technology of traditional secondary lining cutting is to serve as a contrast After platform building cart is in place, using wooden end mould by between arch template and preliminary bracing face space block, from bottom to top annular according to It is secondary to reinforce wooden end mould, then carry out pouring operation.After pouring completion and form removal, wooden end mould is not reaching to recycling, makes It is serious into waste of material;In addition, wooden end mould reinforces, activity duration length low with form removal work efficiency, and race mould is serious, construction quality It is poor.
At present, for above-mentioned wooden end mould the drawbacks of, there is a kind of new secondary lining concreting work in industry Skill is to replace wooden end mould using steel end mould, steel end mould is divided into outboard end mould and medial extremity mould, and both are mutually cut with scissors by hinge Connect, buried water stop during crevice place is set.But due to holding the width of mould to fix, it is non-telescoping, and then chassis mould is not adapted to Change width between plate and preliminary bracing face, outboard end mould can not find stress point, and ultimately resulting in back-adhering waterstop can not have Effect is reinforced, and sealing effect can not be played by often resulting in back-adhering waterstop damage or embedded concrete, influence waterproof effect.
Tunnel Second Lining circular construction joint waterproof construction quality is the important step of tunnel integral construction quality, and its is direct Operation security after being related to.The application of above-mentioned steel end mould secondary lining casting craft is not strong, more Tunnel Second Linings Medial extremity mould is used only in construction, and outboard end mould is still reinforced using traditional wooden end mould.Therefore, the wooden end mould used in the past And fixed type steel end its construction quality of mould construction party decree can not ensure, circular construction joint is set to turn into the weak link of percolating water.
Utility model content
The purpose of this utility model is:It can not be stretched for steel end mould in the prior art to fix back sticking type sealing Band, the problem of causing back-adhering waterstop can not play sealing effect, there is provided a kind of Tunnel Second Lining width is adjustable mixed Native end mould is coagulated, the width of the end mould can be according to the width adjusting between trolley formwork and preliminary bracing face, with effective fixed back of the body patch Formula waterstop, reach its due waterproof effect.
To achieve these goals, the technical solution adopted in the utility model is:
The adjustable concrete end mould of Tunnel Second Lining width, including the medial extremity mould and outboard end mould being hinged, The medial extremity mould is connected on chassis body, and an extension plate, and the relative side slided are slidably connected on the outboard end mould To the radial direction along outboard end mould sector.Because preliminary bracing layer Internal periphery out-of-flatness, extension plate can be to the outer of chassis body Side or interior Slideslip, so that the overall width of end mould can adjust, meet that different preliminary bracing slice width degree, different secondary lining cutting are wide Back-adhering waterstop, can be fixed well by the construction demand of degree, realize its due waterproof effect.
As preferred scheme of the present utility model, the concrete structure being slidably connected includes:It is arranged on extension plate Elongated hole, the fixing axle to match with the elongated hole is provided with the outboard end mould, the fixing axle passes the elongated hole and covered If extension plate is fixed on outboard end mould by nut.By unscrewing or tightening nut, elongated hole can be made to be moved relative to fixing axle, entered And realize the width adjusting of end mould.
As preferred scheme of the present utility model, in addition to telescope support, the telescope support includes pole and expansion link; One end of the pole is fixed on chassis body, and one end of the other end and expansion link is hinged, the other end of the expansion link with Outboard end mould is hinged, and the pole, expansion link and medial extremity mould and outboard end mould surround a triangle.Using chassis as matrix, make Outboard end mould is held out against with three-legged structure, the reinforcing of end mould and secondary lining chassis can be completed.
Further, the expansion link uses flower basket bolt.Using common components, operation is familiar with beneficial to worker, and save Cost.
As preferred scheme of the present utility model, the medial extremity mould is hinged by hinged ear I and chassis body.By In end, mould generally use 6mm steel plates are made, and weigh about 25Kg, are mounted and dismounted using traditional bolt, on the one hand easily fall Cause danger, on the other hand time and effort consuming is installed, influence operating efficiency.Compared to by the way of bolt fixation, it is articulated and connected Mode beneficial to safety in production, and shortens the duration without dismounting.
As preferred scheme of the present utility model, it is provided between the medial extremity mould and outboard end mould for being buried in placing The crack of formula waterstop, and both are hinged by being arranged on the hinged ear II of crevice place.Medial extremity mould and outboard end mould are adopted Connected with hinge mode and buried water stop in clamping, make middle buried water stop installation straight, smoother, really play waterproof work With.
As preferred scheme of the present utility model, medial extremity mould gusset is provided with the outside of the medial extremity mould.Serve Tie up the effect that shape is reinforced.
As preferred scheme of the present utility model, extension plate gusset is provided with the outside of the extension plate.Serve dimension shape The effect of reinforcing.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are:
1st, hold the width of mould can adjust, thoroughly solve the fixation problem of back-adhering waterstop, so as to ensure construction matter That measures is reliable, while has very strong dissemination.
2nd, operating efficiency is improved, the installation and removal efficiency of secondary lining end mould is effectively lifted, and substantially reduces the duration.
3rd, waste of material is avoided, saves construction cost.
4th, construction environment security improves, and is homogeneously connected between each part, in the absence of stand-alone component, no falling risk.
