Abstract
The utility model relates to deep foundation pits, in particular to the bursting of underground continuous wall lithosphere. A protective device for the bursting of deep foundation pit lithosphere comprises a bursting quilt made of junked tires, wherein the bursting quilt is formed by cutting the junked tires into strips, performing mutual lap joint on the strips and waving the strips; and the lap joint parts are fixedly connected by means of bolts. According to the protective device for the bursting of the deep foundation pit lithosphere, the junked tire strips are waved into the bursting quilt, so that the protective device is easy to manufacture; and the tire strips are fixed by means of the bolts, so that the bursting quilt is firm, safe and reliable.
Description
Technical field
The utility model relates to deep basal pit, relates in particular to the explosion of diaphram wall lithosphere.
Background technology
Along with China's building cause development, deep-foundation pit engineering is more and more, some lithosphere deep basal pits appear thereupon, the most tops of such foundation ditch are that the dirt bed bottom is lithosphere, dirt bed excavation rear lower lithosphere need carry out blast working, splash phenomena can appear in the rubble of foundation ditch bottom during blast working, brings safely hidden trouble for engineering-environment.
Current, bring hidden danger that the employing protection network is arranged in order to prevent the foundation ditch explosion to Environmental security, the measures such as bamboo net, but the lithosphere explosion all is hard rubble, existing safeguard procedures can't satisfy safety requirements.Have report to adopt junked tire to be made into protection and be coated on the explosion face and can play certain protective role, but the blast that explosion causes during the lithosphere explosion is lost protective action with the rubble that splashes is easy to protection quilt rushed.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of deep basal pit lithosphere blasting protection device is provided.The utility model adopts waste tire bar braiding explosion quilt, makes simple; Adopt bolt to fix between the tyre strip, explosion is by strong, safe, reliable.
For achieving the above object, a kind of deep basal pit lithosphere blasting protection device, it comprises the explosion quilt that junked tire is made, and described explosion is formed by the slivering of mutual overlap joint and braiding after the junked tire cutting slivering, and this overlap is fixedly connected with bolt.
Explosion of the present utility model is used waste rubber tire cut growth strip; be woven together mutually; form an integral body; overlapped rubber tyre makes and is joined with bolts, and can guarantee globality and the fastness of explosion quilt, and explosion is coated on the explosion medicine hole; behind explosive initiation; blast and the impulse force of rubble can direct effect to explosion by upper, explosion by itself with elasticity rubble and the impulse force alleviation that can produce because of explosion, play the protective effect to engineering-environment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of deep basal pit lithosphere blasting protection device, it comprises the explosion quilt that junked tire is made, and described explosion is formed by the slivering of mutual overlap joint and braiding after the junked tire 1 cutting slivering, and this overlap is fixedly connected with bolt 2.
Claims (1)
1. deep basal pit lithosphere blasting protection device, it comprises the explosion quilt that junked tire is made, it is characterized in that, described explosion by by after the junked tire cutting slivering mutually overlap joint slivering and braiding is formed, this overlap is fixedly connected with bolt.
