Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention, i.e., the described embodiments are only some, but not all embodiments of the invention.
Example 1
Referring to fig. 1, a lining trolley for fire prevention and fire retardation in secondary lining construction of a gas tunnel comprises a portal assembly, a template assembly, a traveling system, a hydraulic system, fixed air wall units 1-10 and an air door passing door hole 11. As shown in the figure, a main framework is formed by a portal assembly by processing 16# I-steel, the main framework is supported on a walking wheel frame, portals are all in threaded connection with lower longitudinal beams, foundation jacks are arranged on the bottom surfaces of the lower longitudinal beams, and during lining, concrete load is transmitted to the portals through templates and is transmitted to the ground through the walking wheels and the foundation jacks respectively.
The running system consists of a running frame, wheel pairs and a power driving device, and the running system is a total bearing component of the trolley and a driving device for the trolley to run. In this embodiment, the traveling system is composed of an active part and a passive part, and four sets of devices are respectively installed below the four gantries. When the trolley travels, the front two sets of driving traveling mechanisms provide power, the traveling motor drives the speed reducer, the driving traveling mechanisms are driven by chain transmission to drive the trolley to travel, and the rear two driven traveling mechanisms follow the traveling.
The main task of the hydraulic system is to lift and stretch the template in place, and the hydraulic system has a small amount of supporting effect, in the figure, the main telescopic rod and the auxiliary telescopic rod are controlled by the main telescopic rod and the auxiliary telescopic rod, and the upper longitudinal beam is pushed to perform translational adjustment through the main telescopic rod and the auxiliary telescopic rod, so that the purposes of adjusting the vertical positioning of the template and demoulding are achieved. The main telescopic rod of the vault adopts 16# I-steel, and the auxiliary telescopic rod adopts
Seamless steel pipe.
The trolley walks to the lining position to erect the mold, and the formwork erection is carried out according to the following steps:
1. starting a hydraulic motor, and adjusting the trolley template to be close to a preset height by using a telescopic rod;
2. adjusting the trolley template to horizontally translate through a telescopic rod to align the template with the lining central line;
3. finally, the trolley side template reaches a preset position, so that the side template reaches a pouring state;
and grouting can be carried out after the mold erection is finished. Before grouting, a release agent needs to be coated on the outer surface of the trolley to reduce the surface adhesion during demoulding. During grouting, grouting is firstly carried out from the lowest row of working windows, when the concrete is about to be flush with the working windows, the working windows are closed, grouting is then carried out from the second row of working windows, and finally top sealing is carried out through grouting openings.
And after the demolding is finished, the demolding is carried out after the concrete is solidified for a certain time, and the hydraulic system is started to separate the side mold plate from the lining surface. After demoulding, the walking system is started to walk and transfer.
During construction, the fixed air wall units 1-10 can isolate overflow of gas, the air door passes through the windproof cloth installed in the door hole 11, the adopted sealing material is fireproof and flame-retardant material with good air tightness, and the door hole air cloth adopts zipper type design, so that the use is convenient.
In this embodiment, the fixed air wall unit and the wind-proof cloth installed in the door opening 11 of the air door are made of fireproof flame-retardant materials, including but not limited to glass fiber materials, fireproof mastic, etc., as long as the purposes of effectively blocking inflammable gas and avoiding gas overflow can be achieved.
The lining trolley provided by the embodiment finishes the whole operation of moving the air wall trolley by repeatedly cycling four working processes of formwork erection, grouting, demoulding and walking.
The above-mentioned embodiments only express the specific embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for those skilled in the art, without departing from the technical idea of the present application, several changes and modifications can be made, which are all within the protection scope of the present application.
