Description
Technical Field
The utility model relates to a tunnel construction field, concretely relates to tunnel mould pouring platform truck concrete placement observation device.
Background
In the tunnel construction process, need pour the concrete and form secondary lining behind the pilot tunnel excavation to support rock, soil etc. around the pilot tunnel, present secondary lining has three kinds of modes of pouring in pouring: pour from the template bottom, pour from the hole of pouring of lateral wall about the pilot tunnel earlier, pour from the template top and pour from the template top again, the requirement of the pumping equipment that needs when pouring is relatively lower for the last kind of pouring, and need not to change pouring position when pouring, the operation of being convenient for, so the last kind is poured the mode and is comparatively commonly used.
However, the height and width of the existing tunnel are usually large, taking the height as an example, the height of the common road tunnel is basically required to be larger than 3.25m, the height of the tunnel used for the trains such as high-speed rails and light rails to pass through is larger, when pouring is carried out, concrete can enter the bottom of the pouring cavity only after flowing downwards for a long distance from a pouring hole at the top, and at the moment, if gas exists in the pouring cavity, bubbles can be formed in the formed secondary lining, the strength of the secondary lining is greatly reduced, and potential safety hazards are easy to generate. At present, in order to promote the gas in the pouring cavity to be discharged and enable the concrete to be completely filled in the pouring cavity, the concrete vibrator is used for vibrating the concrete while pouring, and whether the concrete is filled in the pouring cavity or not can be judged only by whether bubbles emerge around the concrete vibrator and whether the concrete can be continuously pumped into the pouring cavity or not. However, the pouring of the secondary lining is different from the pouring in the construction of common buildings, the secondary lining still has the problem of long length, and the concrete entering the pouring cavity flows downwards from the two sides of the pouring cavity and simultaneously diffuses towards the two ends of the guide tunnel close to the excavation, so that the flowing directions of the concrete in the pouring cavity close to the two ends of the guide tunnel are different, and whether all the positions are filled with the concrete is difficult to accurately judge only through bubbles.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a tunnel mould pouring platform truck concrete placement observation device that can survey concrete poured to whether the improvement is full of the concrete to each position of pouring the chamber and observes and the accuracy of judging.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a tunnel mould pouring trolley concrete pouring observation device comprises an arched head template, wherein the head template comprises an observation unit and two sealing parts, and the two sealing parts are respectively positioned on two sides of the observation unit and detachably connected with the observation unit; the observation unit comprises a plurality of transparent blocks and a plurality of reinforcing blocks, and the plurality of transparent blocks and the reinforcing blocks are distributed at intervals along the width direction of the end socket template.

Further, the transparent block is an acrylic block.
The beneficial effect of this scheme does: the acrylic block has high transparency and high strength, is suitable for machining and easy to thermally form, has low processing difficulty, and is not easy to crack in the processes of transportation, installation and use.
Furthermore, an observation gap for installing the transparent block is formed between every two adjacent reinforcing blocks, and the width of one end, close to the pouring cavity, of the observation gap is larger than that of one end, far away from the pouring cavity, of the observation gap; the width of the transparent block is larger than the width of one end of the observation gap far away from the pouring cavity.
The beneficial effect of this scheme does: according to the scheme, the transparent block is arranged in the observation gap, the section of the observation gap along the horizontal direction is trapezoidal, when the transparent block is arranged between the reinforcing blocks, the reinforcing blocks can deform, and the reinforcing blocks extrude the transparent block, so that on one hand, the phenomenon that the gap is formed between the transparent block and the reinforcing blocks to cause concrete leakage in a pouring cavity is avoided; on the other hand, the transparent block can be prevented from falling outwards when being subjected to the outward pressure of concrete in the pouring cavity, and the concrete leakage can be avoided.
Further, adjacent reinforcing blocks are detachably connected.
The beneficial effect of this scheme does: before the transparent blocks and the reinforcing blocks are installed on other templates forming the pouring cavity, the observation units can be assembled on the ground, and then are uniformly hoisted to the position opposite to the upper part of the pouring cavity for installation.
Furthermore, a connecting plate is arranged between the adjacent reinforcing blocks, and two ends of the connecting plate are respectively detachably connected with the two reinforcing blocks; the connecting plate is opposite to one end, far away from the pouring cavity, of the transparent block.
The beneficial effect of this scheme does: the connecting plate can be connected two adjacent bosses, and the connecting plate in this scheme can not shelter from the bottom of transparent piece completely, and external light can be followed the bottom transmission of transparent piece to the concrete of pouring the intracavity, and the convenience is surveyd the concrete from the tip of transparent piece.
