工地安全通道的生產(chǎn)要點(diǎn)主要包括以下幾個(gè)方面：

The production key points of construction site safety passages mainly include the following aspects:

一、設(shè)計(jì)與規(guī)劃

1、 Design and Planning

確定尺寸與規(guī)格：

Determine dimensions and specifications:

安全通道的凈空高度和寬度應(yīng)根據(jù)通道所處位置及人、車(chē)通行要求確定。一般來(lái)說(shuō)，高度不低于3.5米，寬度不低于3米。

The clearance height and width of the safety passage should be determined based on the location of the passage and the requirements for pedestrian and vehicular traffic. Generally speaking, the height should not be less than 3.5 meters and the width should not be less than 3 meters.

對(duì)于高度在15米以下的建筑物，其進(jìn)出口通道長(zhǎng)度不低于3米；高度在15-30米的建筑物，其進(jìn)出口通道長(zhǎng)度不低于4米；高度超過(guò)30米的建筑物，其進(jìn)出口通道長(zhǎng)度不低于5米。

For buildings with a height of less than 15 meters, the length of the entrance and exit passages shall not be less than 3 meters; Buildings with a height of 15-30 meters shall have an entrance and exit passage length of no less than 4 meters; Buildings with a height exceeding 30 meters shall have an entrance and exit passage length of no less than 5 meters.

結(jié)構(gòu)選型：

Structural selection:

工地安全通道常采用鋼結(jié)構(gòu)搭設(shè)，如工具式安全通道防護(hù)棚，其型材規(guī)格需根據(jù)荷載進(jìn)行核算，并編制專(zhuān)項(xiàng)方案。

Steel structures are often used to construct safety passages on construction sites, such as tool type safety passage protective sheds, whose profile specifications need to be calculated based on the load and a special plan needs to be prepared.

防護(hù)棚地面需硬化處理，立柱與地面可靠連接，確保結(jié)構(gòu)穩(wěn)固。

The ground of the protective shed needs to be hardened, and the columns should be reliably connected to the ground to ensure structural stability.

二、搭設(shè)與安裝

2、 Construction and Installation

基礎(chǔ)處理：

Basic processing:

立桿基礎(chǔ)必須硬化處理，防止地面沉陷。

The foundation of the pole must be hardened to prevent ground subsidence.

立桿沿通行方向通長(zhǎng)設(shè)置掃地桿和剪刀撐，以增強(qiáng)整體穩(wěn)定性。

Install sweeping poles and scissor braces along the direction of traffic to enhance overall stability.

搭設(shè)要求：

Installation requirements:

常規(guī)安全通道立桿縱距不應(yīng)超過(guò)1200mm，防護(hù)棚懸挑尺寸為300～500mm，雙層防護(hù)棚層間距為500～600mm。

The vertical distance of the regular safety passage poles should not exceed 1200mm, the overhanging size of the protective shed should be 300-500mm, and the interlayer spacing of the double-layer protective shed should be 500-600mm.

寬度超過(guò)3.5米或高度超過(guò)4米的安全通道，立桿間距應(yīng)加密或使用雙立桿、型鋼、腳手架管格構(gòu)式立柱，縱向橫桿應(yīng)采用型鋼制作或搭設(shè)承重腳手架。

For safety passages with a width exceeding 3.5 meters or a height exceeding 4 meters, the spacing between uprights should be increased or double uprights, steel sections, and scaffold lattice columns should be used. The longitudinal crossbars should be made of steel sections or load-bearing scaffolds should be erected.

防護(hù)設(shè)施：

Protective facilities:

安全通道頂部采用雙層頂棚形式，間距700~1000mm，滿(mǎn)鋪不小于50mm厚腳手板等硬質(zhì)材料。

The top of the safety passage adopts a double-layer ceiling form, with a spacing of 700-1000mm, and is fully covered with hard materials such as scaffold boards not less than 50mm thick.

頂部正面設(shè)置企業(yè)標(biāo)識(shí)、安全通道和警示標(biāo)識(shí)，標(biāo)語(yǔ)為藍(lán)底白字，上、下弦張貼50~100mm寬紅白警示帶。

The top front is equipped with enterprise logos, safety passages, and warning signs, with blue background and white text slogans, and 50-100mm wide red and white warning tapes posted on the upper and lower strings.

通道側(cè)邊應(yīng)設(shè)置隔離欄桿，引導(dǎo)行人從安全通道內(nèi)通過(guò)，必要時(shí)滿(mǎn)掛密目網(wǎng)封閉。

Isolation railings should be installed on the side of the passage to guide pedestrians to pass through the safe passage, and if necessary, a dense mesh should be hung for closure.

三、維護(hù)與檢查

3、 Maintenance and Inspection

定期檢查：

Regular inspection:

定期對(duì)安全通道進(jìn)行檢查，包括連接件是否松動(dòng)、防護(hù)設(shè)施是否完好、警示標(biāo)識(shí)是否清晰等。

Regularly inspect the safety passage, including whether the connectors are loose, whether the protective facilities are intact, and whether the warning signs are clear.

發(fā)現(xiàn)問(wèn)題及時(shí)整改，確保安全通道始終處于良好狀態(tài)。

Identify problems and rectify them promptly to ensure that the safe passage is always in good condition.

維護(hù)保養(yǎng)：

Maintenance and upkeep:

對(duì)安全通道進(jìn)行必要的維護(hù)保養(yǎng)，如清理雜物、修復(fù)損壞部件等。

Perform necessary maintenance on the safe passage, such as cleaning debris and repairing damaged parts.

定期對(duì)鋼結(jié)構(gòu)進(jìn)行防腐處理，延長(zhǎng)使用壽命。

Regularly carry out anti-corrosion treatment on steel structures to extend their service life.

四、其他注意事項(xiàng)

4、 Other precautions

荷載驗(yàn)算：

Load verification:

在搭設(shè)安全通道前，需進(jìn)行荷載驗(yàn)算，確保通道承載力滿(mǎn)足要求。

Before setting up a safety passage, load verification is required to ensure that the passage's bearing capacity meets the requirements.

防雷措施：

Lightning protection measures:

根據(jù)現(xiàn)場(chǎng)情況做好防雷措施，確保安全通道在雷電天氣下的安全使用。

Take lightning protection measures according to the on-site situation to ensure the safe use of the safe passage in thunderstorm weather.

標(biāo)識(shí)與宣傳：

Identification and Promotion:

在安全通道內(nèi)張掛安全宣傳標(biāo)語(yǔ)，提高施工人員的安全意識(shí)。

Hang safety propaganda slogans in the safe passage to enhance the safety awareness of construction personnel.

綜上所述，工地安全通道的生產(chǎn)要點(diǎn)涉及設(shè)計(jì)與規(guī)劃、搭設(shè)與安裝、維護(hù)與檢查以及其他注意事項(xiàng)等多個(gè)方面。只有嚴(yán)格按照這些要點(diǎn)進(jìn)行操作，才能確保工地安全通道的質(zhì)量和安全性能。

In summary, the production points of construction site safety passages involve multiple aspects such as design and planning, construction and installation, maintenance and inspection, and other precautions. Only by strictly following these key points can the quality and safety performance of the construction site's safe passage be ensured.
