Description

A kind of Super-large-section tunnel secondary lining automatic spray health trolley

Technical field

The utility model relates to highway tunnel construction technical fields, and in particular to a kind of pair of Super-large-section tunnel secondary lining The trolley of concrete progress automatic spray health.

Background technique

Tunnel Second Lining needs to carry out spray maintenance to concrete after the completion of pouring.Since tunnel vault height is higher, Artificial spray is more difficult, and costly using fog gun machine spraying health promotion, easy maintenance is not in place, and secondary lining concrete is caused to support Raw initial stage heat loss is slow, and surface temperature is constantly in higher state, and part is cracked, and intensity rises slow.Chinese patent Shen Numbers 201620331513.5 the device of a kind of entitled " Tunnel Second Lining spraying health promotion trolley " please be disclosed, use one Formula frame is able to achieve in gate-type frame two sides and top installation water pipe and spray head to the automatic health of tunnel double-lining.But the device is only suitable for Ordinary crossing, to Four-Lane Road Super-large-section tunnel, since tunnel side is equipped with wind band and other attached settings, if gate-type frame Its too big supporting leg of span is easy to be interfered by affiliated facility, and span is too small and easy maintenance is not in place.

Summary of the invention

The purpose of this utility model is that the problem difficult for the maintenance of Super-large-section tunnel secondary lining, provides a kind of special Door is used for Super-large-section tunnel secondary lining automatic spray health trolley, not only realizes automatic maintenance, but also can guarantee that health is imitated Fruit.

The technical solution of the utility model is as follows:

A kind of Super-large-section tunnel secondary lining automatic spray health trolley, it is characterised in that: including two it is vertically arranged, It is parallel to each other and arch at regular intervals, each arch includes the crossbeam of a certain altitude from the ground, and every crossbeam passes through perpendicular Supported to the first leg of setting and the second supporting leg, wherein the upper end of first leg and one end of crossbeam are welded, first leg with The first hound is welded between crossbeam, the lower end of the first hound and the lower end of first leg are welded, the upper end of the first hound It is welded on the position between crossbeam and first leg；The upper end of second supporting leg is welded in the middle part of crossbeam between the crossbeam other end Position is welded with the second hound between the lower end and the crossbeam other end of the second supporting leg；The lower end of first leg and the second supporting leg point It An Zhuan not traveling wheel；More vertically arranged perpendicular struts, more perpendicular strut parts from crossbeam are welded at the top of the crossbeam It is not reduced successively to crossbeam both ends height, between every two adjacent perpendicular strut ends, and the perpendicular support close to crossbeam both ends Between boom end and beam-end, connecting rod is respectively welded；Divide between the crossbeam of two arches and between the connecting rod of two arches It is not connected by more lateral bars；Between the connecting rod of two arches, it is erected with from crossbeam both ends to crossbeam middle part top successively Raised step；Two arches first leg outside be arranged a ladder, the two sides of the ladder pass through respectively singletree with The first leg of two arches connects；More upright bars are set in the connecting rod of an arch, and more upright bars are from face tunnel vault It is successively reduced to height on both sides, the end of every upright bar is welded with an arch sparge pipe respectively, the arch sparge pipe and tunnel Arch radian it is consistent, arch sparge pipe is closed at both ends, is arranged one on arch sparge pipe at spacing intervals towards tunnel double-lining The spray head of concrete；A water supplying pipe is connected on the outside of the first leg of an arch, described water supplying pipe one end sets an external water pipe and connects Mouthful, the other end is connected to the sparge pipe.

The utility model is designed for Super-large-section tunnel, and the maintenance of entire tunnel double-lining, knot are able to satisfy on horizontal span It is avoided that on structure and conflicts with adjuncts such as the air hoses of tunnel-side setting again, preferably solve especially big Tunnel Second Lining health and ask Topic, improves construction efficiency, ensure that two lining health quality.
